UNITED STATES CHARLES \V. GLIDDEN, OF LYNN, ASSIGNOR TO JAMES \V. BROOKS, TRUS- TEE, OF CAMBRIDGE, MASSACHUSETTS.

TOP-LIFT HOLDER.

SPECIFICATION forming part of Letters Patent No 427,308, dated May 6, 1890.

Application filed January 15, 1889. Serial No. 296,376. (No model.)

To all whom it may concern.-

. Be it known that 1, CHARLES W. GLIDDEN, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Top- Lift Holders, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.-

This invention has for its object to provide a heeling-machine with a holder to hold the top lift at its breast-corners while the same is being blinded upon the heel in usual manner.

In accordance with my invention a pivoted top lift plate has adjustably mounted on it a block or plate provided with gears which engage teeeth of and actuate the movable clamps simultaneously in opposite directions toward and from the longitudinal center of the top-lift plate.

My invention consists, essentially, in the combination, with a top-lift plate, of an adjustable plate, top-lift clamps, and toothed gear to actuate the said clamps positively in opposite directions.

Prior to my invention devices have been made having arms actuated by a wedge to grasp the side edges of a top lift, and springs have been used to come in contact with the edge of the top lift, and corner-holding devices, one of which is fixed and the other is movable, have been used.

To grasp the top lift readily and hold and position it quickly the clamps used should be so constructed as to be moved positively and in unison in both directions to clamp and unclamp the top lift.

Figure l in top view represents a top-lift plate and holder embodying my invention. Fig. 2 is a side elevation thereof, with a portion of the usual nail-box, on which the toplift plate is pivoted to swing, partially broken away; and Fig. 3 is a partial section of Fig. 2 in the dotted line so.

The nail-box a, of usual construction and common to the McKay and Bigelow heelingmachine, has pivoted to it at a atop-lift plate a herein shown as having a downturned threaded lip a at one end and slotted to receive the shank b of a block or slide plate I), provided at its outer end with a downturned lip Z), in which is loosely held the annularlygrooved shank of a screw b which is screwed into the lip a rotation of the screw efiecting the adjustment of the block or plate I) longitudinally on the top-lift plate or with relation to the nail-box. The block or plate I) has two like screw-studs 2, which serve as pivots for the two toothed gears c d, which engage, respectively, the teeth 0 d of two clamps 0 d herein shown as sliding bars, having lips 3 3, which maybe serrated at their inner sides to engage the edge of the usual top lift-next the breast corners thereof. These bars have like pins 4, which are extended up through slots 5 in the block b,the said pins being connected by a strong spring 6, which normally acts to keep the lips of the clamps closed upon the edge of the top lift. The gears c d have extensions 7, either of which may be grasped by the operator and moved to open the clamps, the said gears being geared together, so that movement of one causes like movement of the other, thus in turn causing equal positive,

movements of both clamps in opposite directions.

The edge 18 of the plate 1) serves as a stop, against which is placed the breast of the heel between its corners embraced by the lips of the clamps. I

I claim-- 1. In a heeling-machine, the nail-box, the top-lift plate, and clamp-carrying plate, combined with clamps to engage and hold the top lift, and toothed gears to move the said clamps positively and in unison, substantially as described.

2. In a heeling-machine, the top-lift plate,

the clamps having teeth, and the block or.

plate carrying the said clamps, combined with gears in mesh with each other and engaging and moving the said clamps, substantially as described. I

3. In a heeling-machine, the top-lift plate, the clamps having teeth, and the block or plate carrying the said clamps, combined with gears in mesh with each other and engaging and moving the said clamps, and with the spring 6, substantially as described.

4. The nail-box a, the top-lift plate 0. piv oted thereon, and a block or plate I), and

Ice

means to adjust the said block longitudinally upon or with relation to the said plate, combined with clamps shaped to grasp and hold the breast corners of the top lift, and with means to simultaneously and positivelymove the said clamps toward and from each other for equal distances, substantially as described.

5. The nail-box a, the top-lift plate a pivoted thereon, and a block or plate I), and .means to adjust the said block longitudinally upon or with relation to the said plate, combined with clamps shaped to grasp and hold the breast corners of the top lift, and with means to simultaneously and positively move CHARLES V. GLIDDEN.
