ARTHUR IV M. FREEMAN, OF NEWARK, NEW JERSEY.

HAME-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 498,469, dated May 30, 1893.

Application filed July 12, 1892. Serial No. 439,753. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR WM'. FREEMAN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hams-Bending Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,referencebeing had to the accompanying drawings, and to letters of reference marked thereon,which form a part of this specification.

The object of this invention is to facilitate the operation of bending and fitting hames to collars, and to secure other advantageous results, hereinafter referred to.

The invention consists in the improved hame bending machine and in the arrangement and combination of the several parts thereof, as herein set forth and finallypointed out in the claims.

Referring to the accompanying drawings,

in which similar letters of reference indicate corresponding parts in each of the figures where they occur, Figure 1. represents, a top plan view of a hame bending machine embodying my improvements and Fig. 2 is a transverse section taken through line at. of the same.

In said drawings A. indicates a bed plate, upon which the working parts of the machine are mounted or of which they form a part,

provided with apertures b. to admit the pas-' sage of screws or bolts for fastening it to a suitable platform orsupport. Mounted upon said bed plate are blocks B. which may be either movable or stationary but preferably movable, and a block 0. movable longitudinally and operated, in the present instance by means of a screw, D. the inner end of which is fitted and works in a socket, in said block 0, wherein it is held by means of a pin or key 0, which registers with an annular groove 0'. formed in said inner end of the screw, as indicated in Fig. 2, and by dotted lines in Fig. 1. Said screw works in athreaded hub, E, formed or mounted upon said bed plate; and in said hub, as also in the block 0, is formed an aperture, f, to admit of the introduction of a lubricant, as will be understood. Said blocksB and Care also provided on the bottom with tongues, g, as indicated in Fig. 2, which work in correspondinggrooves or slots h and t, in the bed plate and are held in position by means of set-screws j and hand bars, Z, as indicated in the drawings. They are also provided with cushions F and G, which are made, preferably, of hard wood, and are secured in sockets formed in the ends of the blocks by means of set-screws, s, so as to be removable and replaced by others at pleasure.

Instead of the wood cushions the faces of the blocks may be covered with leather, rawhide, or other material, softer than iron, the object being to avoid marring the hames in the operation of bending, and more especially when bending hames which have been plated, galvanized, or japanned, as is frequently the case. The faces of the blocks or cushions, as will be observed, are made slightly convex, as a further means to the same end.

The operation of bending is as follows:- The hames are first placed in position between the blocks 13 and G, and are then bent by the pressure exerted thereon by turning up the screw D; the hames being moved longitudinallyfrom time to time during the operation until they are properly fitted to the collar; the said blocks B, may also be adjusted farther from or toward one another, as the circumstancesof the case may require, as will be readily understood.

In cases where the bonding is uniform or no adjustment of the blocks B is required they may be permanently secured to or be cast integral with the bed plate. The form of the latter is not material and may be changed in this respect as desired. It willbe evident, also, that a lever or cam may be substituted for the screw, to operate the block, 0.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a hame bending machine, the combination, with a flat bed plate, of bearing and pressure blocks secured thereto, each of said blocks being provided with a recess in its front or operating end, and the pressure block being located opposite to and intermediate the bearing blocks, a cushion for each block having a stem for securing it in the socket of the block, and also having a rounded operating surface, a" set screw in each block for engaging the stem of the cushion and means for moving the pressure block between the bearing blocks, whereby a hame placed upon the bed plate may be bent into the desired shape, substantially as set forth.

2. In a hame bending machine, the combination, With a fiat topped bed plate, having recesses in its under surface and a threaded hub upon its upper surface, said plate being further provided with means for securing it in position and with three slots, two of which slots are substantially in line with each other and the other slot is located at right angles I 5 thereto a block adj ustably secured in each of the slots, a bar and a set screw for each block,

ARTHUR \VM. FREEMAN.
