Applicahpn-v and May 25, 189s.

Be it known that I, ZALMON G. SHoLEs, a

cago, in the county of `Cook and State of Illinois, have invented certain new and useful Improvements in Ways for Reciprocating Parts of 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 thesame, reference being had to the accompanyingdrawings, and to letters of reference marked thereon, which vMy improvement relates particularly to means for supporting reciprocating parts of mechanism, such as saws, planers, and typewriters, the object being to support reciprocating parts of machinery in such manner as to reduce friction to the greatest extent and to allow the least possible deviation of the reciprocating part fromits chosen path.

In the accompanying drawings: Figure lis a plan of mechanism embodying my improvement. Fig. 2 is avertical section in line Ct--b of Fig. 1

-In said drawings, A is any suitable base. B is'the part to be reciprocated in the direction of the arrows on Fig. 1.

C, C, are rails located at each side of the vided with a longitudinal channel, b.

D, D,:are wheels arranged in a horizontal tending into the channels, b. At each wheel in 'said recesses. Each of said wheels has an Above and below said axle, plugs, D2, are screwed through portions line with the axles, D', and each such plug the axle extends. All of said plugs may be screwed up and down to` give to the wheels, D, an accurate and firm adjustment. Each Serial No. 475,411. (No model.)

' Lvent movement other than rotation, and each wheel may be raised or loweredin prdper 5o alignment with the other wheels and all the wheels may be raised or lowered to give to the part, B, a precise adjustment. The lateral adjustment of the part, B, is "ef- 'fected by shifting the wheels, D, at one side 5 5 of said part, B, horizontally toward or from said part. This is done by shifting one of the rails, C, laterally. The rail, C, at the upper portion of Fig. l, is shown'as being secured immovably to the base, A, while the rail, C, 6o

'Aat the-lower portion is shown provided with mechanism for shifting it. Ears, C2, extend horizontally from said rails, C, over the base,

A, and each lsuch ear is provided with a slot,

c2, elongatedat right angles to said rail, and 65 a' screw, C3, extends through each of said slots. When said screws are tightened, said rail is held immovably. After loosening said screw, said rail may be moved toward and from the part, B, after which said screws may 7o be again s et. To provide for a closely measured and positive movement of said rail toward and from'the part, B, I have provided in front `of the latter a post, E, secured to the base, A, and through said post a screw bolt, 75 E', is threaded horizontally with its forward end extending loosely through the block, E2, which issecured to or is a part of said rail,

C. At each side of said block, E2, said screw bolt has a shoulder or collar, e', which is larger So than the Opening through" said block. Thus said bolt engages said block, E2, at eachside of the latter. When said bolt is retracted from the post, E, said screw bolt draws on the b1oek,E2, and moves n to the saiaraiLC, 85

1 i 95 The reciprocating part, B, may be in the n form of the part shown in the drawings or'of any other form, and it may be recprocated by the hand or by mechanism.

I claim as my invention- 1. The combination with a pieceof mechanism to be reciprocated, of wheels arranged at opposite sides of said part and in engagement therewith, and means for effecting an adjustment of said IWheels parallel to the plane of said wheels and parallel to ,their axes, substantially as described.

2. The combination with the partv B, of wheels D, located at each side of and engaging said part B, vertically adjustable mechanism supporting the wheels at one side of said part B, and mechanism for shifting said April, 1893.
