UNITED STATES PATENT Erica- HENRY DREsEs, or cINcINNATI, OHIO.

METALAsl-IAPING MACHINE.

SPECIFICATION forming part of Letters Patent' No. 544,569, dated August 13, 1895.

Application filed January 21, 1895. Serial No. 535 ,685. (N o model.)

in@ all whom it may concern.:

Be it known that I, HENRY DRESES, a citizen of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Shapers; and I do 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, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form a part of this specication.

This invention relates to improvements in shapers, crank-Shapers, and all similar machine-tools where a cutting-tool carried by a reciprocating tool-carrier or so-called ram acts upon the work supported in a fixed position within the range of its movement. The tool is adjustable to various positions, particularly to and from the work, to cut more or less deep, while the stroke of the ram is adjustable in a manner to vary the length over which the'tool acts upon the work.

By reason of the peculiar construction of these machines, particularly of their frame and the location of the parts thereon which support the Work, only work of limited size, or such where the cutting is to be done near the end lines thereof, can be shaped on them,

while otherwise where the portion to be cut is remote from the end lines such part cannot be brought close enough to come within the reach of the tool. When cutting keyseats in shafts, for which purpose these machines are well adapted and extensively used, this limitation makes itself felt when such keyseats are located remote from the ends of the shaft, which causes the intervening shaft part to interfere by preventing the part to be cut out from coming within reach of the tool. To overcome this defect and adapt such machines for working pieces of metal of limited thickness, but of considerable lengths and at any point of the latter, is the object of my invention, which latter is described in the following specification, together with its operation, parts, and construction, and illustrated in the accompanying drawings, in whichm Figure 1 is a central longitudinal section of the upper part of a crank-Shaper, being a well-adapted representative type of this class of machines. Fig. 2 is a vertical cross-section, and Fig. 3 an end view, of Fig. l. Fig. 4 is a topview of internal details removed.

8 isv the upper part of the frame of such a machine, carrying at one end the adjustable work-support 9. Inside at its top are pro,- vided two grooved guideways l0, opposite each other and adapted to receive the flanges or slides 1l of the tool-carrier or ram 12. One end of this latter overhangs the Work-support and'is provided with the .tool-holder 13 and' the tool 14, secured to it adj ustably with reference to the work. This latter may represent in this case a shaft 15, requiring the cutting of a key-seat located at a considerable distance from the end. This shaft is supported' struction of the ram and the adjustable toolholder thereon, do not form any features of my invention.

The upper end of vibrating arm 16 is forked,

each branch 19 connected to a link 20, the other ends of which connect each to a ange 2l, depending from a nut 22, bored and threaded lengthwise and supported on a screw 23, which is longitudinally confined within the ram.' By means of these links 20, nut 22, and screw 23, the vibrating armis connected to the ram. The position of thislatter on nut 22 may be adjusted by turning screw 23, which then moves in either direction, according to the manner of its operation, through said nut and assumes a dilferent position therein. Being longitudinally con fined to the ram, this latter moves with the screw, and by its position determines the location of the points on the work between which the tool cuts. This adjustment is independent of and is not aected by nor does it affectthe adjustment-of the length of the stroke. ing of screw 23 for this adjustment is by a suitable implement turning an upright spindle 24, having its bearings in the ram and connecting to screw 23 by unter-gearing 25. To prevent nut 22 from exerting anyunequal binding or springing strains Within and against the sides of the ram, induced by its tendency to turn with screw 23, feathers 26 are provided on each side of the former, which take into grooves 27 ou the inside of the ram, by which parts ram and uut 22 are confined to a longitudinal movement on each other and on which parts they slide. The adjusted position of ram 12 or nut 22 is fixed by a washer 2S, caused to im pinge on the former by'lneans of a lock-nut 29, operated by a handle 30 on a lock-screw 31, which reaches through a slot 32 in the rain and passes into nut 22, to which it is secured.

As will be seen, by reason of the forked upper end of the vibrating arin 16, the two links 20, and the two flanges 21 on nut 22, a clear passage is provided centrally below the toolcarrier. This passage is lengthwise extended byproviding openings 33 33 at proper height and in line therewith in the opposite ends of the upper part of frame 8, so that no obstruction Whatever intervenes to the introduction below the tool-carrier of Work of any length which maybe passed in and readily adjusted to any position wherever it may be required.

Having described my invention, I claim as l. In a Shaper or similar machine-tool, the combination ot' the reciprocating tool-carrier, the vibrating arm 16, and the two links 20, to connect the vibrating arm to the tool-carrier, said vibrating arm spreading at its upper end in two branches or forks to the outside of each of which links 20, connect, to provide an open clear space for the purpose described.

2. In a Shaper, or similar machine-tool, the combination of a tool-carrier or ram 12, a nut 22, adj ustably supported Within ram 12, anges 2l depending therefrom on each side, a vibrating arm. 1G, having the two forkbranches 19 at its upper end, two links 20, each connecting one of the fork-branches 19 to one of the depending iianges 21 of nut 22, to connect it to arin 16 for the purpose of .reciprocating it with rain 12, a traine S, on which this latter is supported, having openings 33, in opposite ends in line with each other and inline with the open space between the forked end of arm 16, links 2O and fianges 21 depending from nut 22, thereby providing a continuously open and unobstructed passage clear through the machine. i

In testimony whereof I hereunto affix my signature in presence of two witnesses.
