WARPING AND BEAMING MACHINE.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed March 9, 1917. Serial No. 153,562.

To all whom it may concern:

Be it known that I, GRANT SIPP, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and use ful Improvements in Warping and BeamingMachines, of which the following is a specification.

This invention consists in improvements in machines for warping and beaming, the same having for their objects, first, so to construct a carriage structure for such machines with relation to the usual pair of rods or other ways on which it travels as to reduce to the minimum both friction and lost motion, thus to obtain a free and perfectly rectilinear movement of the carriage structure and more accurate disposition of the warp; second, to provide a certain novel adjustment of the reed in the reed or warping carriage; third, to provide means wherebyto facilitate the control of a warping machine reel, and, fourth, to provide a means whereby, in section Warping, the attendant can with increased facility accurately gage the resetting positions of the warping carriage.

In the accompanying drawings,

Figure 1 is a side elevation of. the warping means, embodying my improvements, of a machine of the kind indicated;

Fig. 2 is a plan view of the warping carriage, the gage, a part of the means concerned n the control of the reel, and the means for supporting'and'causing traverse of the carriage;

Fig. 3 is a rear elevation of the carriage and said means;

Fig. i is a sectional view on the line 4-4 of Fig. 2; V

Fig. 5 is an end elevation of the gage;

Fig. 6 shows a side elevation, as seen from the inside of the frame in Fig. 1, of the means for controlling the reel;

Fig. 7 is a plan view of said means; and,

Fig. 8 is a vertical sectional view thereof.

a is the frame of the machine, vb'the reel, and c a suitable brake engaging the brakeband (Z of the reel. According to a wellknown construction, the reel is driven by the peripheral contact of friction wheelc .with the band d of the reel, the friction wheel 0 and a cone pulleyj being fast on shaft 9 which is journaled in a fulcrumed arm h. The parts e, f, 9, during Warping,

sure being removed from the treadle and the friction wheel falling out of contact with the band cl, the brake brings the reel immediately to a stop.

There is the usual pair of parallel stationary shaftsm affording ways on which travels, parallel with the reel axis, the warping carriage at, its traverse being effected from a rotary screw ovjournaled in the frame between the shafts m and having a sprocketandl-ihain connection 2) With the shaft of the rec The carriage n is equipped on the under side with a bracket structure q cored to receive the rear shaft on, and in each end thereof are journaled. four rollers 1" engaging the top, bottom, front and rear sides of said rear shaft. Forward ofthe two-point anti-friction bearing means thus afforded there is arranged in the carriage another rollers which runson the top of the front shaft m. The rollers r and 8 permit the carriage to travel substantially without friction along its ways, while the two sets of rollers 1' also serve to hold the carriage from any lost motion whatever-an item of great importance in warping, since the slightest unintended movement of the carriage other than perfect rectilinear movement is likely to lead to serious defects in the warp, as by overlapping or undue spacing of the threads, in laying it on the reel; further, the construction is such that the carriage can, if necessary in effecting repairs, beelevated on the rear shaft m as a fulcrum, having first removed the screw, 0.

For the adjustment of. the reed t, toward and from the reel said reed is mounted in a bracket a arranged to slide on the elevated longitudinally slotted portion of a bar go bolt d t the t p of arriage n ne pendicular relation to the reel, said bracket being equipped with suitable means to for clamping it to the bar.

The warp carriage is disconnectively con nected with the screw 0 by the worm-wheel y arranged on a spindle 2 on which isthe. hand-nut 2, the spindle being set in a bracket 3. depending from the carriage and which is abutted on either side by the worm-wheel and nut. When the carriage is to be traversed by the screw the worm-wheel is clamped fast to the carriage by tightening upthe nut; in order to render the carriage movableindependently of the screw, the nut is loosened, permitting the worm-wheel to turn freely on the spindle a.

In section warping, the sections of warp aresuccessively laid on the reel side by side, and due to the traverse each is wound helicallyvon the reel. The start of the winding of each section should begin in such relation to the beginning of the preceding section that, their two adjoining lateral threads will be spaced exactly the same as any two threads in either. The gage shown in Figs.

, 2 and 5 is designed to promote accuracy in re-setting the carriage to the proper starting point following the winding-on of one section and before beginning to Wind the next. There is a member l formed with a collar 4: to embrace one shaft m and a fork 4 (penetrated by but not engaged with-the threading of screw 0) to engage the other (Fig. 5'), and projecting laterally from it, parallel with said shafts, a rigid rod 5. There is also a device in the form of a collar 6 slidable on one shaft on and penetrated by said'rod', and between this collar and member 4 and also penetrated by said rod another member 7 Members 4 and 7 have set screws 8 and 9, respectively, to bind them immovably to the shaft m; collar 6 has a set screw 10 to secure it in fixed relation to the rod. In the present instance, the carriage traverses from left'to right, and is adapted to be re-set from right to left. Be fore. starting the first traverse collar 6 is secured to the rod, and member 42 to the shaft by, adjusting their set screws, collar 6 abutting the carriage (at bracket 3) and being spaced from member l so that withmember 7 abutting either member a or collar 6 there would be a space between the other of these latter and member 7 equal to they width of each section. After the first traverse, of the carriage is completed 1nemher 7 is made to abut member 4 and secured by its screw 9 and then, having released screw 8, member 4 is shifted to the left, carrying with it collar 6, until the latter abuts member 7 2 The carriage is now re-set until it abuts collar 6, thus covering its traverse distance plus the width of each section and comingin its new position exactly where it should'be for properly starting'thenext secnaeases tion. When the secondv traverse is completed, member 7 is re-set and secured to the shaft in contact with member 4, then mem her 4 shifted again to the left until collar 6 abuts member 7 and finally the carriage moved back into contact with collar 6, being then in exact position for the winding of the third section. This operation is repeated for gaging the new position of the carriage following each traverse.

In order to keep the reel rotating by automatic. means for holding the lever depressed and yet provide for facile and quick release of the treadle and prompt stopping of the reel I provide the following mechanism: The free end of the'lever 2' plays in a vertical slot of a bracket 11 and is overhung by alug 12 011 the bracket. lhere is a latch 13 fulcrumed in this bracket on a vertical axis, one endunderlying the lug 12 and having a lateral projection 14 formed with an under-- neath shoulder 15; theother arm-of the latch is connected with a pin 16' projecting from the bracket by a light spring 17 which holds the latch normally in the position shown in Fig. 7, and connected-to it is a horizontal op erating rod 18 which extends across the machine andmay be supported bya hook19depending from the warping carriage. If the operator desires to leave the reel in motion without holding his foot on the treadle, he depresses the treadle and by'shifting rod 18 -to the right swings the end of the latch having the projection 14: into such position that such projection will. overlie the (depressed) lever i, upwardly abutting the lug 12. The friction offered by lever z and lug 12'wil1 be sufiicient to prevent spring 17 from retracting latch 13. The friction wheel 6 will thus be held against the band of the reel',,keeping the latter in rotation. To stop thereel, the operator has only to move rod 18 tothe left to clear projection 14' from'lever' i' so that spring Z will cause the free end of'l'ever i to be'raised and the friction wheel to fall out of contact with the band d," or' the same result can be accomplished by depressing and immediately releasing the treadle j, the spring 17 operating in the interim between depressing and releasing the treadle to 'retract latch 13 out of detent relation to lever i. j

Having thus fullyvdescribed my invention, what I claim as new and desire to secure by Letters Patent is 1.
