The present invention. has to do with machines for nailing, stapling and rivetingarticles While it is susceptible oi-many uses, it is particularly adapted for boot and shoe making and repair shops, harness. making, and repair shops, for shops specializing in making or repairing hand bags, golf bags and the like, and for shops having to do Wi h the making and repair 015 all stich artic esis One of the important features to. be considered in connection with this machine is he fa that it is capable ofnailing, stapling and riv eting articles together. This is: accomplished. by providing the machine with three r more '25 mechanisms, each operated. independent y of Y the other, one of which. is capable of; nailing one article to another, as for instan e, h application of halfsole to a shoe; another is capable of stapling one article to another,

' for closing seams. in articles, affixing Pa che and the like; and finally, in the present ma chine, two additional mechanisms are 910-; vided, one for peening the ordinary type oi soft metal rivets, and the otherfor clin hing tubular and split shank rivets.

The fastening members above referred to, in this instance four all told, are mounted upon a slidable support at the head of the machine, This support is so. constructed that it may be moved back and forth in order to bring one or the other of the mechanisms into operative position, during which period the remaining mechanisms are inoperative. However, if at any time it is desired to. change to one of the other of the three inoperative mechanisms, it is easily done by moving the slidable support until the desired mechanism is in operative position.

The other important feature to be considered in connection With this machine, is the fact that it is capable of'operating on articles of various types and shapes. This has been accomplished, aside from the fastening means heretofore enumerated, by pro riding the machine with Work supports that 1931; Serial No. 520,033.

fragmentary de ail a s pport anvi for Similar numerals indicate similar parts throughout the several views:

Referring now to the drawings it will be noted that this machine consists of a frame which has an elongated base 1, provided with a pedestal portion 2 from which rises a vertical standard 3. The sides of the base 1 rise somewhat above its upper surface or bed 4 as flanges 8, which in connection with the bed 4 form a guideway or slide 6 for a bed plate 7. Flange plates 5, secured to the flanges by means of bolts 9, extend over the edges of bed plate 7 and maintain it within the slide.

7 The upper face 7 of bed plate 7 is pro vided with two transversely arranged portions 10 whichrise above the face of the bed plate. The portions 10 are in the nature of spaced, parallel flanges and definea transverse guideway or slide 7 for the pedestal plate 11 which is held therein by the plates 12 which are secured to the portions 10 by means of bolts 13.

Plate 11 has a sleeve or socket portion 14 in which is seated the shaft or column 15. About shaft 15 is a spring 16 upon which seats a sleeve 17. The upper end 18 of shaft 15 is threaded to receive the nut19 which bears upon the upper end of the sleeve 17. In the operation of the present machine, the sleeve 17 is subjected to blows or shocks, as will appear hereafter, and the purpose of the spring 16 is to absorbsuch shocks. The operation of the spring 16 for this purpose is controlled by the nut 19 which permits increased or decreased compression thereof, thereby regulating the rebound of sleeve 17 under blows.

Sleeve 17 has an upper and lower horizontal arm, 17 and 17 respectively. Both arms have coaxial vertical bores, not shown. The bore in the upper arm has a greater diameter than the bore in the lower. Carried within the bore in the upper arm is a horn support member 20. The bore in the lower arms is threaded to receive the threaded rod 21 which has its upper end seated within a socket or re cess in the lower end of horn support 20. The lower end. of rod 21 (Fig. 1) is provided with a handle 22 for threading or unthreading it in the arm17, while the upper end is held against removal from the lower end of member by a pin 24 held by that member in a manner to ride in a peripheral groove 23 in the upper end of rod 21. Hence when the rod 21 is raised or lowered by threading or unthreading it, the horn support will likewise be raised or lowered. The up l per arm 17 is of split construction so that it may be caused to grip the horn support against movement through the medium of the threaded member 25 which draws the split portions together. Horn support 20 has A r 1 7 1. enlarged upper end 20 in which is a socket for receiving the butts 26 of either the horn 27 or the work support member 28.

The standard 3, at its upper end, has a broad vertical face 29 which terminates at its upper and lower edges in horizontal flanges 30 and 31. A head plate 32 is mounted to slide upon the face 29, and is held thereon by the flange plates 33 and 34 which overlap its edges. Flange plate 33 is secured to flange 30, and flange plate 34is secured to flange 31 by means of bolts 35. The foregoing construction permits the head plate to be moved back and forth on the face 29. In order to aid in such movement plate 34 has rack teeth 36 out along its upper edge with which mesh a pinion 37 on shaft 38, which shaft is operated by hand wheel 39. Shaft 38 is journaled in frame 40 projecting from plate 34.

j The present machine contemplates driving and clinching nails, (in shoes and the like) driving and clinching staples, driving and clinching tubular and split shank rivets, and peening flat head and washer type of rivets. In order to do this it is necessary to provide a distinct type of driver or peening device for each purpose, that is to say, there is a mechanism for driving nails, another for driving staples, another for clinching tubular and split shank rivets and lastly one for peening the flat head and washer type rivet. These four mechanisms are mounted to the head plate 32, and one or the other may be moved into operative position by turning hand wheel 39 which moves plate 32 back or forth until the desired mechanism is in its correct position. 7 During the period that one of the four mechanisms is in operative position, the other three of course are not in position to operate.

Projecting from head plate 32 are four heads, 41, 42, 43 and 44 respectively. These heads are spaced from plate 32 and from each other. They have downwardly projecting arms 41, 42, 43 and 44, which terminate in guide heads 41", 42", 43 and 44. Heads 41, 42, 43 and 44 are bored vertically to receive plungers 45, 46, 47 and respectively. At the upper ends of the several plungers are fastened caps 49 provided with spaced ears and between these caps and the tops of the heads are springs 50 which urge the plungers upwardly until sleeves 51., one on each plunger, engage the lower end of the respective heads and arrest further upward movement.

Plungers 47 and 48 have reduced lower portions 47 and 48 respectively. which eX- tend through the guide heads 43 and 44". The reduced portion 48, which may be termed a peening hammer, has a tapered end portion 48 within the base of which is formed a cup or concave peening recess 52. In Figure 13 two pieces of material A and B are to be fastened to one another by the rivet 53 whose upper end or shank 55 is peened upon gmeees Washer 54: The upper end or shanhis enned by repeatediy striking it with the cup por don- 52 of the hammenthe plunger 458 being repeatedly raised lowered for this purpose. The mechanism for operating; the re speeti ve plungerswill be describedhereafter, Y The next; to' be considered is the; mecha nism for clinching tubular or split shank rivets-. This is shownin detail? in- Figure 12'. The lower end of the reduced portion 47', hereafter referred to as the clincheror clincher hammer, of plunger has an axial bore 56' within which is seated the cone tipped spreader bar 5?.- Bar 57 is subject to upward and: downward movement the bore 56, limitedhowever by pin 58 in its upperend which travels in slot59 in the wall oi the clincher. Upward movement or the spreader is resisted by the spring 60 seated between it and the end of the bore. The purpose Oftll'lS construction is to allow a slight movement of the spreader While the work isbeing centered thereunder. the illustration a split shank rivet 61= is being used to fasten two pieces ofwork, C and D to ,one another- It is to be understood that during the operation of clinching the rivets-the work is resting on a solid work support which will be described in detail later. in the operationof this machine the plunger 47 is moved downward, the cone end of the spreader contacts with the end of the rivet shank, the tip of the cone within the shank, and at contact momentarily remaining stationary, the clincher continues to move downward during the interval o-finaction of the spreader, until the upper endot. slot 59 engages pin 58-, whereupon. both spreader and clincher travel together, The spreader separates or curls outwardly the upper vends of the shank and provides the impetus for it" to curl downwardly, which downward curling or' bending of the shank is aided byithe hammer face 62 of the'clincher, which assists in bendingthe ends downand finally clinches them on the face of the work.

The next to be considered are the two mechanisms for nails and staples, and with the exception that onedrives" nails and the other staples, their mechanisms are alike and they will be described together. Pl'ungertfi operates the nail driving mechanism, and plunger 46' operates the stapling mechanism. Plungers 4:5 and 46 have reduced lower pertions 45 and 46 respectively, which a chore- 7 after referred to asdrivers or hammers The lower portionsof the drivers travel in the interior of the barrel, driver 45 within bar'- rel 6'3, driver 46 in barrel" 64. Barrel 63 is vertically movable in guide head ll and 64 in head 42".. Each barrel has an elongated slot 65, and each driver has a pin 66" which travels in the slot of its barrel. Between the tops of the barrels and the undersides of the heads 45 and 4:6 as the case may be are arranged springs 67 which urge the barrels or" staples are tedinto the interior" of the respective barrelstlirough the chutes 63 and 64 connecting therewith. The lower portion 73 otdrivertfi is reduced in diameter to allow it to enter pas agew y 70, and likewise the lower portion 74E of driver 46 is flattened to permit it to enter passageway 71.

In View of the tact that the operation of the stapling mechanism is identical to that of the nailing mechanism, a description thereof will be limited to the latter. The work G'H is centered beneath the passageway 7 0' and downward movement is imparted to plunger 45 this', of course, moves driver 45 downward. As the driver moves downward, barrel 63 moves with it, urged by the spring 67, so; that their positions with regard to each other do not change until the lower end of the barrel contacts with the work After the barrel contacts with the work its downward movement is arrested thereby, at the same time downward movement of plunger and driver are'momeutarily arrested to enable anail 75 to be fed into chute 63, down which it travels to com'e torest on the work, it is still in passageway 70 as indicated by the outline 7 5". The nail is] then ready to be driven into the work, which is done by sharply lowering; the plunger and driver, the latter strikes the nail with su'iiicient force to drive it through the work. During the driving of the: nail or the staple, as the case may be, the work rests upon a clincher head, which clinches the nail. As before stated. the operation o'fi the'stap lin z mechanism is identical to the nailing mechanism. In Figure 11 this mechanism is shown stapling the work EF.

In this view the staple 17 6" is fed through chute 64;" where it drops to the bottom of the passageway 71, to the position shown by ou line 176. liter the nails or staples have been driven, the springs 50 and 67 return the plungers, drivers and barrels to normal, raised inoperative position.

The next to be considered is the means for operating the several mechanisms just dcscribed. This is of the foot operated or treadle type and consists of a bell crank treadle 76 pivotall'y' mounted at its elbow to the bracket 77,- which bracket is mounted to the base 1. The free arm of the treadle is pivotally connected to one end of the link 78, and the other end of such link is pivotally connected to one armor the bell crank 79, which is pivotally mounted at its elbow to the, standard 3. The free arm of crank 79 is pivotally connected to one end of link 80. The other end of link 80 is pivotally connected to one end of lever 81. Lever 81 is arranged to be pivotally supported midway its ends on the upper end of the rocking support 82, which is pivotally mounted at its lower end to the standard 3. Each cap 19 has two ears 49 which are spaced apart sufficiently to permit the free end of lever 81 to enter therebetween. This end of such lever and the ears are provided with corresponding pin holes for receiving the pin 83, which is held in place by cotter 841. In View of the fact that the caps and ears form the upper part of the respective plungers, it will be seen that the foregoing mechanism provides the operative means for depressing the plungers when. treadle 76 is depressed. However it is to be understood that lever 81 is connected to but one plunger at a time. In Figure 2 the lever is connected to plunger l7 operating the mechanism for clinching split or tubular rivets. In the event it is desired to operate one of the other mechanisms, the lever 81 is disconnected with the plunger to which it is attached, head plate 82 is moved, either one way or the other as the case may be, by means of hand wheel 89 until the desired mechanism is in position, and then the lever 81 is connected to the plunger of this mechanism. The proper position for the desired mechanism is directly in front of the vertical center line of the standard 3, which position, as shown in Figure 2, is occupied by the mechanism for clinching tubular or split rivets.

Two types of work support members are shown in the drawings. One is the horn 27, mostly used in shoe repair work, and being well known in the art, does not need any description. 'The other indicated by the numeral 28, consists of an elongated horizontal portion 85, hereafter termed an arm, and a downwardly curved butt portion 26 to seat in the socket in the portion 20 of the horn support member. This member is hereafter termed a work support. In the drawings but one support of this type is shown." However in actual practice, it is contemplated that several of these supports shall be used in connection with one machine, and that they sh all differ mostly in the length of their arms 5. The supports 28 are substantially made in order to resist the shocks which they undergo. The outer end of arm 85 is cut down below the normal upper surface thereof to provide a seat 86 for removable anvils hereafter described, and a vertical socket (not shown) is provided therein for the shanks of such anvils. On referring to the drawings, five of these removable anvils are shown. In Figure 4, 87 is an anvil for clinching staples. It is provided with a shank 88 which seats in the socket of the arm heretofore referred to. The upper face 89 is concave, and when the legs of a staple 177 are driven'on it by the staple driver heretofore described, they are bent toward each other and clinched.

Figure 5illustrates a clincher anvil 90 for clinching nails driven by the nail driving mechanism. This anvil has a convex face 91 to aid in clinching nails, and a shank 88 for seating on the arm 85. It is to be understood that these anvils support the work which is being nailed or stapled, as the case may be, and that the nails or staples are driven through the work and clinched on these anvils. In Figure 6 is illustrated an anvil 92 for supporting the ordinary copper or soft metal rivet wherein its shank is peened over a, washer. This anvil is provided with the usual shank 88, and its upper face has a recess 93 in which the rivet head is seated with its shank directed upward. The anvil 9 1, for tubular rivets as shown in Figure 7, includes a shank 88 and a centering pin 95 on the upper face thereof which enters the base of the rivet shank as the rivet rests head downward thereon. igures 8 and 9 illustrate an anvil 96 for split shank and slotted head rivets. This anvil also has a shank 88, a recess 97 in its upper face is provided for the rivet head. Across the face of this anvil is arranged a slot bar which fits into a slot in the head of some rivets of this type. In the event that the heads of the rivets used are not slotted, then the bar 98 may be dispensed with, or an anvil of this type used that is not provided with such bar.

With respect to the different classes of rivets which may be used in connection with this machine, it is sometimes necessary that they be held on their anvils during the interval they are being inserted in the work. Provision is here made for so doing, and such is in the nature of a bar 105 which rests upon the upper surface of arm 85, and is held in that position for sliding back and forth by the straps 106 which are fastened to the arm. The bar 105 extends the full lengthof the arm, and its outer end is provided with a cut out portion 107 which slips over the rivet head and partially embraces the shank. This is done by moving the bar outwardly, which is easily accomplished by grasping the upturned handle portion 108. After the rivet has been inserted in the apertures provided therefor in the work, then the bar 105 may be withdrawn from the rivet head. In Figure 2, the numeral 109 indicates the outline of a golf bag which is about to have a rivet inserted in its wall. It is here evident, that if it were not for the fact that the rivet is firmly held on its anvil by bar 105, it would become dislodged as the. bag is being positioned on the arm 85.

When a work support member with a long semis t lized, i m y be ioundadri-s e to b ase it to s te a d d st ngth Thi i i eneby rr viding a remov l bra ng ba whi h ha on a d se u ed by be 5. 0 to arm and the o h r en se ur d by olt 10. t h m suppor m mb r 20.- 2111 tion to this it may be found adyisabie to eliminate the lEG'bOllIlGl of the work support occasioned by thespring'16, and this is done by providing the sleeve 17 with apertures 102 four in number, which are arranged in pairs diametrically opposite each other, and the alignment of each pair is at right angles to the other pair. The column 15 is pro vided with a diametrical aperture (not shown) which upon revolving sle-eve17 on its axis, will coincide with one or the other pair of apertures 102. When this has been done, two wedges, 103 and 104 are driven on one another through the coinciding apertures, as shown in the drawings, and this in efiect solidly unites the sleeve 17 to the column 15.

The foregoing completes the description of this machine. It will be seen therefrom that it is a general utility machine, by that is meant that it is not confined to any particular class or work upon any particular class of objects. It may be used in connection with shoemaking and cobbl-ing, bag making and repairing, bootmaking and repairing, harness making and repairing and other work. In shoe repair Work, for instance, half soling, the column 15 is moved close to the standard 3. This is done by moving the bed plate 7 and the pedestal plate 11 in their respective slides. In this class of work the horn 27 will probably be found more suitable as a rest for the shoe than the work support 28. In case of making repairs to boot legs, such as stapling seams, it will probably be found desirable to use a work support 28, possibly one with a medium size arm 85. In this event the stapling mechanism is substituted for the nailing mechanism as heretofore .described, and the boot leg is drawn on arm and the work accomplished. It is necessary to position the column 15 so that the anvils which seat upon the seat 86 are positioned directly below the stapling mechanism. In other work, a work support with an extreme- 1y long arm may be required, as, for instance riveting the seam in the wall of a golf bag, in which event it will be necessary to position the column 15 a considerable distance from the riveting mechanism to allow or compensate for the length of the arm 85. In-

Figure 2 an outline of a golf bag 109 is shown as'having been drawn upon arm 85 in order that it may be riveted in a region proximate its base. This is but one of the many examples illustrating the versatility of this machine.
