In tlfe' figures, there are three supporting structures to the operating mechanismthe trestle 1, supported from the ceiling of the operating room; and the two standards 2 and 3 resting upon the fioor 4. The trestle 1 is suspended by rods 5 from the ceiling beams 6. Sprocket wheels 7, 8 and 9 engage a continuous double chain 10, and they are journaled on stub shafts fixed in the respective brackets 11, 12 and 13, mounted upon opposite sides of the trestle 1. The chain is held in tension by means of a carriage 14, which is constantly pulled by a weight 15, connected thereto by a cable 16 passing over a pulley 17, journaled upon a shaft 18, fixed in the trestle 1. The carriage 14 is provided with rollers 19 engaging tracks 20 on the trestle 1. The chain 10 passes around sprocket wheels 21, fixed on the shaft 22, journaled upon the frame of the carriage 14. The chain 10 is supported in its length by the guide 23. In the forward end of the trestle 1 is journaled a shaft 24, upon which is fixed a pair of spaced sprocket wheels 25.

Referring now to the standards 2 and 3, there are mounted thereon, the respective brackets 26 and 27 adjustably fixed upon the respective ways 28 and 29. integral with the respective standards 2 and 3. Journaled in the sides of the bracket 26 is the shaft 30, upon which are spaced and fixed a pair of sprocket wheels 31, engaging the double chain "10. Similarly, journalcd in the sides of the bracket 27 is the shaft 32, u on which are spaced and fixed a pair of sproc et wheels 33, which also engage the double chain 10. Upon releasing the brackets 26 and 27 from their fixed relation to the respective ways 28 and 29, they may be adjustab y positioned vertically by means of the threaded shafts 34 and 35, which the brackets 26 and 27 engage. The shafts 34 and 35 are turned by the respective hand wheels 36 and 37 fixed to them. The various sprocket wheels 31, 7, 8, 33, 9, 21 and.25, in succession engage the chain 10, which in'motion, passes over these sprocket wheels in the order just mentioned, so that the lower parts ofthe chains 10, pass forward, as they turn about the lower parts of the respective pairs of spocket wheels 31 and 33. The two lengths of the doublechain 10 are joined together and equally spaced throughrespectiveout their length, by means of the plurality of gripping units 38. An individual gripping unit 38 is illustrated in detall in Figures 6, 7, 8, 9 and 10, wherein there are fixed to the opposite links 39, of the chains 10, tubular pieces 40, in which is fixed the shaft 41. Journaled upon the shaft 41, and hanging beneath it, is the yoke 42, in the central part of which, are journaled, at 43 and 44, the respective legs 45 and 46, which are normally drawn together by means of the tension spring 47. At the lower ends of the legs 45 and 46,.are feet 48, to each of which is attached, by means of the screws 49, a refractory jaw 50, having notches 51, where they engage the neck of the bottle. To the upper ends of the legs 45 and 46, are journaled the rollers 52 and 53, which engage the wedge 54, of the tubular rocking element 55 which is journaled upon the shaft 41.

The rocking element 55, has a shoulder 56, positioned to engage a lug 57, integral with the yoke 42. There is provided between flanges 58, integral with the rocking element 55, an annular recess 59, concentric with the shaft 41, which recess 59, is engaged by the lug 60, which is integral with the yoke 42, the purpose bein to maintain the rocking element 55, in a Iongitudinal position'uponv the shaft 41. The rocking element 55, has a crank extension 61, to the outer end of which is journaled a roller 62, whose axis is parallel to that of the shaft 41.

' Integral with the yoke 42, is a crank extension 63, positioned at an angle therewith and having ournaled at its outer end, a roller 64, the axis of which is parallel to that of the shaft 41. A horn is fixed in the yoke 42.

A set of stationary cams, for operating the gripping units as they pass around the sprocket wheels 31 and 33, is provided in connection with each of the brackets 26 and 27. A detailed description of these cams is given below, in connection with the description of the operation. The cams of the set, in fixed relation to the bracket 26, of the receiving end of the device, are shown in Figure 11, and are numbered 66 and 67. The cam 66 is contacted by the roller 64, and the cam 67 is con tacted by the roller 62 of the gripping unit 38, to position thejaws 50 to travel in a certain defined path and to open the jaws 50, and then permit them to close upon the neck of the bottle, as the gripping unit passes the same. The cams of the set, fixed in relation to the bracket 27 and shown in Figure 12, are numbered 68 and 69. The cam 68 being positioned for contact with the roller 64, and the cam 69 being positioned for contact with the roller 62, of the gripping unit 38, so as to define the path of the jaws 50 to let the bottle down practically vertical in the lower end of the path and to hold the jaws open as they pass the bottle just released. In connection with the operation of the roller 64, on the beveled gear 85, which is in mesh with an- *jvithjthe fhorn 65, to keep- 5 1701181 necting the shaft-32, of the sprocket wheels 33, with the driving shaft 73, journaled in the standard 3, (see Figure 13) there is fixed upon the shaft 73, a pulley 74, adapted forblt'connection to a motor. Fixed on the oposite end of the shaft 73 is aleft hand worm 5', which meshes with a worm gear 7 6, {fixed upona vertical shaft '77, which is journaled upon the shaft 77 and to be turned therewith.

The gear 81 meshes with another gear 82, fixed upon the shaft 83, which is j ournaled in an extension 84, of the bracket 27. The 0pposite end of the shaft 83, has fixed thereto a other beveled gear 86, fixed upon the shaft 32, thereby com leting the connection between the pulley. 4 and the shaft 32, and permitting the vertical adjustment of the bracket 27, while the gears remain in mesh.

Considering 110w the distributor 87, at-

' tached to the standard 3, a post 88 is positioned in fixed relation thereto by means of the pieces 89 and 90. Integral with the post 88 is a bracket 91, having a flat track portion 92 on top thereof. Within the post 88, is journaled a vertical shaft 93, having fixed at its upper end, a shoe 94, which rests on.

the top of the post 88. Fixed at the lowerend of the shaft 93 is a crank 95, having on the arm 96 the gear segment 97, concentric with the shaft 93. Upon the arm 98 is a slotted rim section 99, concentric with the shaft 93 and having slots 100 and 101 adjustably engaged, respectively, by the long pins 102 and 103, these pins being fixed to the section 99,

by means of nuts,'threaded thereon.

Referring to the upper part of the distributor, there 'is fixed upon theshoe 94, a

' plate 104, having the end next the shoe 94,

broadened out. This plate 104 extends away from the shoe 94 and is strengthened by longitudinal members 105 and the bridging 106,

" ment 97. The worm 109 is fixedupon the on each side thereof. Beneath the plate 104,

there is fixed a roller bracket 107, having journaled therein a roller 108 which rides upon the curved flatptrack 92. For swinging the plate 104, there is provided a right hand worm 109, in mesh with the gear segshaft 110, which is journaled in an extension 111 of the piece 90. The shaft, 110-is also journaled in the bearing 112, fixed upon the standard 3. At this hearing. 1112, there. is

atha tah s-provided a leaf s ring 70,, fairly curved to "coordinate in 'pressedf .i j contact with the cam 68, as the 'unit'f r iterate .t iwh T e leaf Spr ng 701's aa eat aa albar '71, which is adjustablyj ffixed by the screw 7 2,to the upper part of the bra'Qket27. Considering now the part confixed upon the shaft110, abeveled gear 113,

which its in mesh with another'beveledf gear? 114, fixed upon the shaft ,115"(see.,F. i'gure '17)..'

the shaft 115 has journale'd thereon the cone pulley 116 which is positioned longitudinally y the 'collars 117 ,and' 118, fixed upon the shaft 115. Spaced from the cone '116'journaled upon the shaft 115, is the lutch-ing ele ment 119, positioned longitudinally, by the sprocket wheel 122. The shaft 115 .has a: s uare portion 123, in sliding engagement collars 120 and 121, fixed upon the shaft 115, concentrically fixed upon the clutchin elewlth the annularly-grooved collars 124 having teeth 125 integral with each end thereof,"

and adapted for engagement with the teeth v126 of the cone 116 and the teeth 127 of the clutching element 119. The collar 124 has a square hole engaging the square'portion 123 of thesha-ft 115.

The sprocket wheel 122, on the clutching element 119, is connected by the sprocket chain 128, with the sprocket wheel 129, fixed to the shaft 73, so that the clutching element 119 runs at a constant speed due to that of the driving shaft 73, and revolves upon. the shaft" 115, unless locked thereonbyfthe clutching collar 124. The cone 116 is revolved by means of a belt 130 connected with the cone 131,-fixed upon the shaft 132, which is jour-'- naled in the standard 3. The shaft 132 runs at a constant speed,-being connected with the shaft 73, through the worm 75, the gear 76, the

shaft-77, the beveled gear 133. fixed upon the shaft 77, the smaller beveled gear 134, in mesh with it, and journaled upon a stub shaft 135, fixed upon the standard 3, the sprocket wheel 136, fixed concentric with the beveled wheel 134, which is connected b the sprocket chain 137, with the sprocket w eel 138, fixed upon the shaft 132. By changing the position of the belt 130, upon the pulleys 116 and 131, the speed of the cone pulley 1 16 is changed.

Referring now to the clutching device upon the shaft 115, the clutching element 119 revolves in an opposite direction to that of the which is fixed upon the shaft 140, j ournaled 1n the standard 3. The opposite end of the shaft 140, has fixed thereon the piece 141,

which has a lower extension 142, upon which is fixed the horizontal pin 143, positioned to be I engaged by either of the verticalpins 102 or 103. The piece 141 also has an upward extension 144, in which is fixed a-rod 145, to the upper end of which is fixed a weight 146, which serves to quickly and forcibly rock the shaft 140, one way or the other, to throw the clutching collar 124 into engagement with the cone pulley 116 or the clutching element 119. when started in either direction by means of either of the vertical pins 102 and 103, engag ing the pin 143.

Positioned below the distributor 87, is a traveling conveyor belt 147, which turns about the wheel 148, fixed upon the shaft 149, journaled in the standard 150. The conveyor being rovided to carry the bottles away from the distributor 87, to a leer, or if desired, the bottle handling device may be so designed, as to have the standard 3 in close proximity to the leer, having the bottles pass from the distributor 87 directly to the moving bottom of the leer oven.

Considering now the means provided for moving the bottles along the l'ate 104, to make room for the successive eposlting of the bottles a on the late 104, and at the same time to disc ar e tie bottles intermittently from the distri utor, there are adj ust-ably fixed upon the face of the standard 3, above the plate 104, two guides 151 and 152, the same bein adjusted relative to one another to accommodate bottles of different diameter. Positioned between the plate 104 and the guides 151 and 152, and back of the spot where the bottles are deposited, is a rod 153 which has connection with the cam 154, which is fixed u on the shaft 32, oscillatin the rod 153 throug the cam lever 155, which is pivoted on a stub shaft 156 fixed in the bracket 27. A rod 157 is adjustably fixed in the lower end of the lever 155. Upon the rod 157, is adjustably fixed the block 158, in which is adjustably fixed the rod 153. The cam arm 155 is oscillated by means of the engagement of the roller 159, with the cam groove 160.

In operation, assume that bottles are regularly supplied at the receiving end of the bottle handling device, in a iven position, where they are successively pic ed u automatically, by the gripping units at t e standard 2, and carried to the standard 3. Motion is given to the chain 10 b means of the connection of the sprocket w eels 33 with the driving shaft 73, through the shaft 32, the bevel gears 86 and 85, the shaft 83, the bevel gears 82 and 81, the shaft 77, the gear 76 and the worm 75, fixed u on the shaft 7 3. An adjustment of speed 0 the chain 10 is effected through the size of the pulley 74 and its connection with a motor, or by varying the speed of the motor.

To better explain the functioning of the gripping unit parts with the cams, as the bottle is gripped and released, parts of F igures 11 and 12 are drawn diagrammatically. Considering the action of taking hold of a standing bottle by the neck, assume that a table top, the surface of which is represented by T in Figure 1, is placed directly under the sprocket wheels 31, in proximity thereto, and that the bracket 26 has been so adjusted in position, by means of the screw 34, that a bottle of a given size, will have its neck in the path of the jaws 50, at a point, in this path, where the jaws automatically close. The bracket 26 is then fixed upon the standard 2 for this position, during a run of a given size of bottles,

by arrows 162 on the cam 67.

bottles having necks of different diameters within certain limits, which is made possible by the elastic grip, due to the spring 47. Having adjusted the device for a given size of bottle, assume that the chain 10 moves, taking the unit 38 down from its position shown, through successive positions, wherein the small circles 41 represent the successive positions of the shaft 41 as the unit 38 turns about the sprocket wheels 31 and the large dot 50, on the jaws 50 travels through the path taken by the dots 50 as governed by the action of the cams 66 and 67 upon the parts of the unit 38. The lines 42" drawn between the circles 41 and the respective dots 50", represent the tilting or vertical positions assumed by the plane of the yoke 42, passing through the shaft 41 and the dot 50' on the jaws 50, in passing around the wheels 31. Points of contact of the rollers 62 and 64 on the respective cams 66 and 67 corresponding with their positibns relative to those occupied by the shaft 41, by the small circle41, are represented by arrows 161, on the cam 66, and

The cam 66 has a curved surface 66 which draws nearer the shaft 30 on-the way down, the surface of the cam 66 then changes at a point 163 to a surface 66", concentric with the shaft 30 and merges into a curved surface 66 of short radius which changes at the point 164 to a surface 66, concentric with the shaft 30, but of shorter radius than the surface 66. There are three surface formations on the cam 67, viz, the vertical surface 67', the curved surface 67*, concentric with the shaft 30, and the curved surface 67, most of which is circular, having a center near the path of the shaft 41 and terminating in a small reverse curve. The surfaces 67 and 67 connect at the point 165 and the'surfaces 67 and 67 connect at the point 166. Asv the roller 62 passes down the surface 67, the rocking element 55 is turned out of the vertical and the roller 64 traveling along the surface 66 'assiststhis turning and tends to hold the place as the roller 64 passes the point 163 of.

the cam 66 and is held so as the rollers 64 and 62 travel the concentric portions 66 and 67", of the respective cams 66 and 67, the roller 64 enters upon the portion 67 of the cam 66 and the aws 50 remaining open approach the j about by the co-action of the spring 47, and

causing the jaws 50 to snap onto the bottle B at its neck, after which the rollers 62 and 64 leave the earns 67 and 66, and the bottle bemg spring gripped, is carried up and around the sprocket wheels 7 and across to the :procket wheels 8, when it descends toward;

e sprocket wheel 33 at the standard 3. Previous to starting the device, the bracket 27 is adjusted in position with respect to the plate 104 of the distributori87, or to any horizontal surface adjoining the standard 3, upon which the bottles are landed. The adjustment of the bracket 27 is effected by means of the screw 35 and is made with res ectto the height of the bottle B, being han led e by the device.

Referring now to Figure 12, the same system of dots, small circles and arrows is used as those in connection with Figurell, but the dots and arrows follow different lines. The

V, series of dots ofFigure 12, follow a reverse curve, so designed, that the lower part of this curve is nearly vertical, indicating that the bottle B, in its movements is brought directly over the spot where it is subsequently deposited and let down upon that spot in a vertical position, having been given a chance to be righted to a vertical position during its movement in dwelling in the lower vertical part of the-path of the jaws 50. The cams 68 and 69 are designed, as are the .cams 66 and 67, to cause the jaws 5O to'travel and operate in the path indicated by the large dots 5O and 50 respectively. The cam 68 has a surface, the curved portion 68, of which, draws nearer the shaft 32 on the way down,

A and changes'tothe concentric portion 68 at the point 167.

The cam 69 has a short vertical surface portion at 69, for contact with the roller 62. The portion 69 is concentric with the shaft 32 and is connected by the curved portion 69, of short radius, with the portion 69. The portion 69 terminates at the point 168, directly under the shaft 32.

Considering now the functioning of the parts, as the shaft 41 passes around the wheels 33, afterthe unit 38' leaves the full line position shown in Figure 12, the horn 61 comes in contact with the leaf spring 70, which causes a tilting of the unit 38 from a, vertical plane, as shown by the lines 42", as the jaws 50, pass down through the successive positions of the dots 50 and the shaft 41 lines radiati n from each of the small circles, in the path of the shaft 41, connect with the points of contact of the rollers 62 and 64 with the arrows 169 and 17 0, on the respective are wide open, leaving the bottle B to rest in the broken line position BB, upon the surface of the plate 104, or any other horizontol' flat surface desired. The jaws 50 remain open as the rollers 62 and 64 traverse the concentric portion 68 and 69 of the respective cams 68 and 69, so that the jaws 50 pass clear of the bottle. In both cases of picking up a bottle and of depositing it, the chain 10 runs constantly uniform, consequently, the shaft 41 of each unit 38 travels at a uniform, speed while the cams modify the. move-mcnt of the jaws confining them to the paths indicated by the dots, besides opening and closing the jaws 50 as explained above. In the design of the device, there preferably passes a unit 38 for each revolution of the sprockets 31 and 33. k v v The chain 10 is maintained in tension by the carriage 14 which adjusts itself in posi-- oo is close to the belt 147, the movements of the same are derived from the driving shaft (0. Referring to Figures 13 to 18 inclusive, the

oscillating movement of the top plate 104, is

caused by oscillations of the shaft 93 through the connection of the gear segment 97 with the worm 109, which turns first in one direction then reverses, according as the collar 124, slidingly keyed on the shaft 115, engages the pulley 116 or the clutching element 119. If the clutching element 119 is engaged, then the plate portion ,105 swings rapidly from the dotted position 105 to the full line position, while if the teeth 126 on the pulley 116 are engaged, then there is a slow movement from the full line position to the dotted osition 105, the rate of the latter movement eing fixed bythe position of the belt 130 upon the cone pulleys 116 and 13 In Figure 17 the belt 130 is shown connected with the pulleys 116and 131 for the fastest speed, during the distribution of the hottles on the conveyor belt 147. The movement of the swing top 105, is regulated for the diameter of bottle carried, and for the rate at which they are deposited from the units 38, of. the conveyor. The changing-of engage'ment of the clutch collar 124, from the clutching element 119 to the cone pulley 116 and vice versa, is effected by the pins 102 and 103, which alternately and slowly push the, pin 143, to one side or the other, so that the weight 146 passes through a vertical position from which it falls, rapidly changing the position of the clutch collar 124 from its partial engagement with the cone 116 to full engagement with the clutching element- 119 or vice versa. Adjustment of the position of the pins 102 and 103 on the slotted segment 99 is made to regulate the amount of angle through which the extension 105, of the plate 104, swings.

The bottles are deposited u on the plate 104 between the guides 151 an 152 in front of the rod 153, and as each bottle is deposited, the cam 154 causes the cam lever 155 to move, giving a forward movement to the rod 153 to push the bottle from the position B to the broken line position B of Figure 15,

as the bottle moves forward between the' guides 151 and 152, pushing previously deposited bottles ahead of it along the extension 105 and out of the end upon the conveyor belt 147, to be carried further, as to a leer.
