ARBOR-PRESS.

Specification of Letters Patent.

Patented Feb. 9, 1915,

Application filed January 2, 1914. Serial No. 809,883.

To all whom it may concern:

Be it known that I, JOHN B. FLINT, a citizen of the United States, residing at Boston, in the county of Sufiolk and State of Massachusetts, have invented new and useful Improvements in Arbor-Presses, of which the following is a specification.

This invention relates to improvements in arbor presses and has for its object to provide a simple and easily operated arbor press which will be capable of receiving and positioning a large variety of arbors, as to different diameters thereof, and a large variety of sizes and shapes of pieces into which the arbors are to be forced. In order to position this large variety of arbors and pieces of work into which they are to be forced, or from which they are to be removed, I employ a plate upon which the work directly rests and this plate, which may be termed a supplementary workplate or support rests upon a stationary work-support having a notch therein.

The supplementary work-support is provided with a V-shaped slot extending thereinto from the front edge thereof so that a large variety of diameters of arbors may be accommodated by said V-shaped slot while the pieces into which these arbors are forced, or from which they are to be forced are securely supported and rest upon the supplementary worksupport in which said V-shaped slot is provided. In addition to the supplementary work-support being provided with a V-shaped slot, this work-support has its efliciency greatly augmented by being transversely movable upon the stationary work-support of the arbor pressthat is, the supplementary work-support can be moved forward and back or sidewise or at any angle so as to bring the V-shaped slot at any desired position relatively to the plunger of the press, and by this combination of the supplementary work-support with the v-shaped slot and by the capability of moving this supplementary work-support to any desired position relatively to the plunger of the press I obtain a press capable of taking practically all sizes of arbors, from large to small, within the extreme capacity of the arbor press employed.

The supplementary work-support hereinbefore referred to is so attached to the press that the same may be quickly positioned and still at the same time its movement may be limited, and furthermore the same is so at tached to the press that while the supplementary work-support is universally slidable upon the bed of the press it is not detachable therefrom and will always be found 1n convenient position to be adjusted relatively to the plunger of the press to receive the work.

In addition to the V-shaped slot in the front of the supplementary work-support,,I also provide a series of holes of different diameters which are to be used in cases where it is desirable to support the Work into which the arbor is to be pressed or from which it is to be removed close to said arbor and entirely therearound, and these holes are preferably arranged in such manner that they may be quickly positioned relatively to the plunger of the press, this positioning being obtained by sliding the supplementary work-support forwardly or backwardly, as the case may be, beneath the plunger, the operator being assisted in this positioning operation by the specific construction hereinafter clearly set forth in this specification.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a side elevation, partly in section, of an arbor press embodying my invention. Fig. 2

is a sectional plan taken on line 2-2 of Fig. 1, with the supplementary work-support or plate shown in two positions, one of said positions being illustrated by dotted lines.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 4 is the frame of an arbor press, the same being provided with a work-support 5 notched at 6 to receive the ends of arbors which are to 'be forced through work placed on said work-support. A plunger 7 of the usual type, is reciprocatorily arranged in a bearing 8 in said frame 4: and adapted to be reciprocated by a pinion 9 engaging teeth 10 on said plunger and a hand lever 11 connected with said pinion to rotate the same.

The plunger 7 is arranged to be reciprocated at right angles to the surface of the wor -support 5 for the purpose of forcing arbors or mandrels from or into the work. A supplementary work-support or plate 12 is mounted on and movable transversely of said work-support 5, said plate being preferably formed of two layers of material 13 and 1a, the lower layer 1 1 being preferably formed of material such as cast iron, while the upper layer 13 is formed of relatively harder material, such as steel, and is prefe erably hardened to prevent chipping or wear caused by contact with the work into which the arbors are forced, said layer 13 being secured to the portion 14 by screws 15.

The layer 13 is formed in two parts for convenience in manufacture and is preferably joined along the line 16. The plate 12 has a V-shaped slot 17 extending there through from top to bottom and opening at the front edge 18 of said plate and is adapted to be adjusted to fit various sizes of man drels alining with the plunger 7, said V- shaped slot being employed when it is de sired to force a mandrel or arbor from a piece of work which is of such a thickness that it does not require a support entirely around said arbor. This, however, would not always be the case, as it is often necessary to force arbors or mandrels into work of such a thickness that the support must entirely surround and fit said mandrel; otherwise said work would be bent or in jured by the pressure applied thereto. For this purpose the plate 12 has been provided with a plurality of holes 19 extending laterally through said plate, each of which is of a different diameter, thus adapting said plate to substantially all sizes of arbors, said holes being arranged in such a manner about said plate that they may be severally brought into alinement with the plunger 7. It will, however, be observed that said holes 19 are arranged at a suilicient distance from the edge of the \l-shaped slot 17 and the sides 20 of said plate in order that said plate will extend completely across and rest upon each said of the notch 6 in the worksupport 5, whereby said plate will be supported simultaneously upon opposite sides of each of the holes 19.

It is essential that the plate 12 be permitted to move freely on said work-support 5 in substantially all transverse directions, that is, both transversely and longitudinally of said plate, in order that the holes 19 may be quickly moved into alinement with said plunger, and a handle 21 has been pro-- vided to facilitate the adjustment thereof. In addition to the desirability of having the plate 12 move freely on the work-support 5 in substantially all transverse directions, it is also desirable that said plate should be at all times connected to the frame of the press in such a manner that it will be in position for the operator to employ and will not be liable to become detached therefrom and lost. To accomplish this result an arm 22, preferably consisting of a rod, extends from the rear of the plate 12 through an opening 23 in the front wall of the frame eland into a recess 24 formed in said frame. A stud 25 is adapted to slidably engage said rod 22 and has a cylindrical stem 26 projecting upwardly therefrom and pivotally engaging the frame 4, permitting said plate to be moved on the work-support 5 substantially in all directions transversely thereof, but preventing the upward movement of said plate relatively to said work-support.

The movement of the plate 12 is suflicient to permit any one of the holes 19 and the slot 17 to be placed in alinement with the plunger 7, but beyond this said plate is prevented frombeing moved by the ends of the opening 23 against which said arm 22 is adapted to strike, while a screw 27 limits the outward longitudinal movement of the rod 22 relatively to the stud 25.

It will be seen that the holes 19 are arranged in two series 28 and 29 upon opposite sides of the V-shaped slot 17, each of said series being radially disposed relatively to the cylindrical portion 26 of the stud 25. Thus when the arm 22 is. at the end 30 of the opening 23, as shown in dotted lines, the forward and rear movements of said plate will cause the holes in said series 28 to substantially aline with the plunger 7 providing said arm is kept in contact with said end of said slot, and should the plate 12 be moved transversely of said work-support until said arm 22 is at the end 31 of the opening 23, the series of holes 29 may likewise be successively alined with said plunger by the forward and rear movement of said plate.

In the operation of the device the plate 12 is adjusted or moved until a hole of the proper diameter or the portion of the slot 17, which corresponds to the diameter of the mandrel or arbor which is to be forced into or removed from the work, is brought into alinement with the plunger 7, after which. the handle 11 is revolvedto move said plunger down against the arbor to force the same through the work-supported by said plate, as illustrated in Fig. 1'.

Having thus described my invention what I claim and desire by Letters Patent to secure 1s:
