DAVID PHILBRICK, OF MANCHESTER, NEW' HAMPSHIRE, ASSIGNOR TO HIMSELF, AND ELMER TOWNSEND, OF BOSTON, MASSACHUSETTS.

ROTARY LAST-HOLDER.

To all whom it may concern:

Be it known that I, Davie PHiLRIcK, of h/Ianchester, in the county of Hillsboro and State of New Hampshire, have invented an Im'p'roved Rotary Last-Holder; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, denotes a side elevation of it. Fig. 2, a front elevation of it, Fig. 3, a longitudinal and central section made so t-o represent the plane of the jack as in the same plane with the rotary arm.

In these drawings A represents the jack on which the last is supported by means ot' the toe and heel rests, a., Z), it being confined thereto by a screw c, acting against a movable or turning heel pin (Z, which turns o n a pin c, and is inserted in the rear part of the last, as shown in Fig. 3.

This last holder is hinged to a joint pin B, by a clamp hinge C, of peculiar construction. The clamp pin f, of the hinge is formed with a cylindrical enlarge-nient'or head g, which rests against the end of the male or entering part L, oit' the hinge, and turns in the adjacent projecting part i of the female portion ot the hinge. Besides this, the clamp pin has a male screw 71, arranged on it (as seen in Fig. upon which clamp nut Z is tted. On screwing torward the clamp nut, the male part of the hinge will be drawn against one projecting portion only of the fork or female part ot the hinge and thus may be clamped thereto. By means of the clamp hinge, the last holder can he turned laterally in a plane passing longitudinally through the axis of the joint pin, B. This joint pin B, is so applied to one end of a curved arm E as to be capable of revolving' thereon and of being clamped thereto by means of a clamp nut and screw as shown at F, in the drawings. The curved arm E, also turns on a horizontal pin H, and against a circular bearing plate I, and a separate recessed concentric bearing plate K. This latter plate K) is intended to be affixed to the side of a bench and is formed with a circular recess for the reception ot the circular plate I, and so as to make between the two, a circular groove for the reception of the head and part of the shank o1" a clamp screw, L, which extends through the curved arm and carries a clampA nut, M, as shown in, the drawings. The circular plate, I, is separate from the recessed plate K, and is confined in position by means ot' the center pin H, and a screw and nut ap plied thereto, as shown at O.` in the drawing. This construction of the bearing and support piece of the curved arm enables the said arm and the clamp screw to be easily removed at any time from their recessed bearing plate, this being occasionally necessary for cleaning pegs, chips or dirt, out of, and oiling the groove in which the head of the clamp screw may move.

F rom the above it will be seen that by means of the revolving arm the last holder may be turned around so as to'be either inverted or have its curved radial supporting arm fixed in any desirable position in the path of its revolution; also that the last holder may be revolved in a plane at right angles to the plane of revolution of the supporting arm, and that besides this, the last holder may be tipped or turned laterally either way with reference to the pin which sustains it on the supporting arm. All these motions are of great advantage in enabling a workman to properly adjust the last in the positions most favorable for either pegging or sewing a shoe to advantage and particularly for sewing it.

I do not claim a cylindrical journal, and a circumscribing socket held together, not only by a groove ruiming around the joun nal but a pin or screw extending from the socket into the groove. Nor do I claim at taching the radial arm to a revolving plate held to the circular face of a support or standard by a clamp but- That I do claim isl. My improved support piece of the radial arm, viz., as made of a. standard plate K, recessed as specified, and a circular plate, I, formed to enter the recess of the plate K, and to make with such a dovetailed groove or its equivalent for receiving the head of the clamp screw, L, the two plates being confined together by a screw and nut, constructed and operating as and for the purpose set forth.

2. I also claim the improved last holder hinge and Clamp as made essentially as above described, viz.7 with its clamping and hinge pin Constructed with a head to bear against one enel of the male part of the hinge and to turn and be Supported in one of the prongs of the forli of the hinge 1S explained.

In testimony whereof I have hereunto set my signature this 5th day of November,

DAVID II-IILBRICK.
