MACHINE FOR REPAIRING PIGKER-APRONS.

Specification of Letters Patent.

Application filed September 20, 1909.

Patented June 13, 1911. Serial No. 518,639.

To all whom it may concern:

Be it known that I, NEWTON VVILLIAMs, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented a new and useful Machine for Repairing Picker- Aprons, of which the following is a specification.

The present invention has reference to improvements in machines for repairing picker aprons. These aprons, as is generally understood, consist ordinarily of a canvas belt spanning a pair of spaced leather belts and arranged upon the upper faces of the same, the canvas belt being in turn provided at intervals with spiked battens. During use, it frequently happens that these battens become broken or otherwise injured, and hence must be removed, and new ones substituted. The detachment of the battens under such circumstances is, however, a matter of extreme difliculty, owing both to the very considerable weight of the belt and to the fact that rivets are employed for securing the battens to the belt, it being necessary to cut off the tops of the rivets in order to remove the battens.

It is the object of my invention, therefore, to produce, a machine whereby the repairing of the belts will be materially facilitated.

A structural embodiment of the invention is illustrated in the accompanying drawings, wherein:

Figure l is a plan View of the improved machine, Fig. 2 is a side elevation thereof, Figs. 3 and 4 are end elevations of the same, Fig. 5 is an enlarged detail View of the movable foot and its associated adjusting devices.

In said drawings, a and A indicate the two upright legs which are mounted on a suitable base A and support upon their upper ends the table B, the leg A being rigidly secured to said base. Said table is substantially rectangular in shape, and its floor is formed with a similar opening 7) into which the panel H, hereinafter referred to, is arranged to move. At opposite sides of the *table are arranged the longitudinal shafts D and (Z provided, respectively, with pulleys c and C connected by a belt 0', the pulley 0 having a crank handle 0 attached thereto. Intermediate their ends, the shafts D and (Z are studded with spikes as indicated by the characters (Z and (Z, the spikes being designed to engage the picker belt, (not shown), and advance or retract the same according to the direction in which said shafts are rotated. There is also connected to the table a pair of adjustable transverse guides E and 6 arranged in spaced parallel relation, the fastening bolts 6 and e of said guides being slidable in the slots f and F formed in the table floor. The above-mentioned panel H is likewise rectangular, and its dimensions are appreciably smaller than those of the opening Z). Said panel is revolubly connected to a pair of vertical racks z" and 2' by means of its trunnions 7L and It which are fitted in open ings in the upper ends thereof. To impart the requisite vertical movements to said racks, there is provided a pair of pinions 2' and I mounted on a longitudinally arranged horizontal shaft 2' journaled in openings in the legs a and A and rotated through the medium of a hand wheel or the like. Panel H is faced on one side with wood and on the other with metal, and is adapted to be fastened in raised position by means of suitable latches J, j, 7' and j In order to permit the accurate positioning of the picker belt with respect to the machine, the leg a is provided with a movable foot K, (Figs. 3 and 5), the stem of which is slidably fitted in a groove formed in said leg and is retained in position by means of a set screw or similar device. To raise said foot, a strip 70 formed at its'upper end with a finger piece is fastened thereto. Owing to the provision of this foot, it will be possible, when the'same is raised, to introduce one edge of the picker belt therebeneath, and then position the upper stretch of said belt between the guides E and e which have been previously adjusted in conformity with the width of the belt. After the introduction of the belt beneath said foot, the latter may then be depressed and fastened in place, to clamp the belt in posi tion.

The table floor, at opposite sides of the opening 5 is formed with holes Gwhich are so located as to lie directly beneath the rivets in the picker belt, when said belt is in position on the table, such arrangement enabling the cut rivets to be forced through said holes with a punch or other suitable implement.

The operation is as follows: The-panel H, with its wood face uppermost, is first raised into position in the opening I) and locked by means of the latches J, j, i and j', (which are pivoted to the side members of the table and below the fioor thereof). In this position, the upper face of said panel will lie substantially flush with that of the table floor. The picker belt is then introduced beneath foot K and its upper stretch passed over the table and between the previously adjusted guides E and e. The rivets lie at that time above the wooden face of the panel and may be cut in any suitable manner, the said wooden face afiording a surface that will not turn the edges of the cutting tools, after which the belt is shifted by the spiked shafts D and (Z so as to bring the cut rivets directly over the holes G, whereupon they may be punched out through the belt and its battens, and through said holes. The broken batten is then removed and replaced by a new one which is placed in position above the panel, said panel having been lowered at the completion of the removal of the rivets and subsequently raised with its metal face uppermost. The new batten is then riveted to the belt, the panel constituting a work plate during this operation If the belt is to be repaired at another point, it is shifted into proper position by the rotation of shafts D and d and the afore-mentioned cycle of operations again takes place; otherwise the belt is removed from the machine.

WVhat I claim and desire to secure by Letters Patent of the United States, is:

1. In a machine of the class specified, the combination of a table across which the upper stretch of the belt is adapted to extend, a pair of legs for supporting said table, a base to which one of said legs is rigidly secured, and a foot connected to the other leg and adapted to be raised above said base to permit the lower stretch of the belt to be introduced beneath it.

2. In a machine of the class specified, the combination of a table across which the up per stretch of the belt is adapted to extend, a pair of legs for supporting said table, a base to which one of said legs is rigidly secured, a foot connected to the other leg and adapted to be raised above said base to permit the lower stretch of the belt to be introduced beneath it, and means for clamping said foot in adjusted position.

3. In a machine of the class specified, the combination of a table across which the upper stretch of the belt is adapted to extend, a pair of spaced guides adjustably mounted on said table and arranged to engage the opposite side edges of said stretch, a pair of legs for supporting said table, a base to which one of said legs is rigidly secured, and a foot connected to the other leg and adapted to be raised above said base to permit the lower stretch of the belt to be introduced beneath it.

4. In a machine of the class specified, the combination of a table across which the belt is adapted to extend, said table being formed with holes through which the rivets in said belt are adapted to be forced after the same have been cut, and means for shifting said belt into position to aline said rivets with said holes.
