To @ZZ whom, t may concern,.-

Be it known that we, VINCENT A. TAYLOR, of Bedford, and JAMES D. OLOUGH, 'J r., of Cleveland, in the county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Traverse Sanding-Machines; and we do hereby declare the following to be a full, clear, Vand exact description of the invention, such as will enable others skilled in theart to which it pertains to make and use the same. Our invention relates to improvements Vin vertical traverse sandpapering, smoothing or polishing-machines, the Vprimary object being to construct a machine wherein one or more vertically-arranged sand-papering or polishing-drums are employed, which drum or drums have bearing at either end, and wherein the upright frame that carries said bearings and the drum or drums, is reciprocated vertically during the rotation of the drum or drums in the operation of the machine, by which construction the edges of irregular Work can be accurately squared, smoothed or polished, the

sand-papering, smoothing or polishing-drum' or d rums not being liable to vibrate in the Operation of the machine.

A preferable construction of machine embodying our invention is illustrated in the accompanying drawings, wherein- Figure l is a front side elevation of the same, and Fig. 2 is a left hand side elevation relative to Fig. 1. Portions are broken away and in section in said figures to more clearly show the construction. Fig. 3 is an enlarged top view in section on line 3-3, Fig. l.

Referring to the drawings, A A designate two upright standards, frames or housings` that are located a suitable interval apart and connected at the top and bottom by crossbeams or girders C and D. The sandpaperin g, smoothing or polishing drum or drums are located at the front side of 'the machine. The machine illustrated has two of said drums marked E E that are arranged vertically and located a suitable distance apart. Each drum is operatively mounted upon a shaft G that, at or near each end of the respective drum, has bearing in a box g rigid with a frame H that is adapted to slide up and down between the pairof housings or upright frames A A,

said reciprocating-frame engaging suitable slide-ways a formed in the supporting-frames or housings. The arrangement of parts is such that the forward side of the sand-papering, smoothing or polishing drum or drums is somewhat forward of the upright supportingframes or housings, and a table I, suitably supported from said frames or housings, is provided at the forward side of the machine for receiving the work whose edges are to be squared, smoothed or polished, said table being cut away or slotted vertically, as at l', to accommodate the location and operation of thesandpapering or polishing-drum or drums.

Suitable means are employed foreffecting the reciprocation of the drum-carrying frame H during the rotation of the drum or drums. Preferable means for the purpose consists of a verticallyarranged double-feed-screw K that is shown located centrally between the two sand-papering, smoothing or polishing drums, and, at its upper end, terminates in a plain or unthreaded portion K' that extends upwardly through the top cross-beam C, and has two collars k fixed thereon above and below said beam, respectively, to prevent endwise movement of the screw. The feed-screw also has'bearing in a box K2v rigid with reciprocating-frame H, said connection of the feed-screw with said frame also assisting in guiding and steadying the frame in the operation ,of the latter. Feed-screw K being of the double-feed variety,-the same having a right handed and a left handed vspiral groove,-is adapted to feed frame H in oppo` site directions alternately, frame H carrying' a swiveled dog L adapted to engage the grooves of the screw. Said grooves are in open relation with each other at their ends and the arrangement of parts is such that dog L will ride up the one groove in the screw, and down the other groove, said dog carrying frame H with it. Feed-screw K, preferably at its lower end, is intergeared, as at M, with an upright shaft O that is located a suitable distance rearwardly of and arranged parallel with the feed-screw. Shaft O is suitably supported from frames or housings A, and, at its upper end, 'is provided with a drivlng-pulley 0. Shaft O is provided witha drum, O2, the

IOO

length whereof is equal to the traverse of the sand-papering, smoothing or polishing drums and the pulleys on said drums. Drum O2 is shown operatively connected, by means of a single belt, P, with pulleys R R, operatively mounted, respectively, upon the dierent smoothing or polishing drum supportingshafts, said pulleys R R being provided, respectively, with an external' flange R at either end to prevent automatic displacement of the belt from the pulleys. The belt, of course, must travel with the sand-papering, smoothing or polishing-drums in the reciprocation of said drums. Frame H and the sanding-"drums are counterbalanced to facilitate the reciprocation of the same. A preferable manner of counterbalancing said drums is by means of weights, S. Two weights S are employed in the machine illustrated and are attached to the one end of a cable, rope or chain, T, that leads thence upwardly to and over a pulley U suitably supported by the adjacent supporting-frame or housing A, and thence leads to reciprocating-frame l-l to which it is suitably attached, as at T.

The pieces of wood or work whose edges require squaring, smoothing or polishing are placed upon table l and fed in a horizontal plane back and forth across the lrevolving sanding or polishing surface of the sandingdrum or drums.

Our improved machine is not only exceedingly simple in construction and durable, but the facing or polishing surfaces cannot possibly Vibrate during their operation, and hence the edges of the work can, with great facility, be accurately squared, smoothed or polished.

Vhat we claim isthe combination of two upright supportingframes or standards, a reciprocating frame located between and adapted to slide up and f down said frames or standards, said reciprocating-frame bearing one or more vertically arranged sand-papering, polishing or smoothing drums, means for actuating said frame,

, and means for rotating the drum or ydrums y K engaged by said dog, suitable means for rotating said screw, and suitable means for roy tating the aforesaid drum or drums, substantially as set forth.

3. In a machine of, the variety indicated, the combination of two upright supportingframes, housings or standard-s located a suitable interval apart, a vertically arranged reciprocating frame located between and adapted to slide up and down said housings or standards, two vertically-arranged sand-papering, smoothing or polishing-drums borne `by said reciprocating-frame and located a suitable interval apart, a vertically-arranged rotating drum or elongated pulley suitably supported rearward of the sand papering, smoothing or polishing-d rums, a pulley operatively connected with each of said smoothing f or polishing-drums and operatively connected with the aforesaid elongated pulley by a single belt, a table for receiving the Work to be sand-papered, squared or smoothed, and suit- 3 able means for actuating the aforesaid recip- 1 rocating-frame, thev arrangement of parts be- A;ing substantially as shown, for the purpose ispecied. l. In a machine of the variety indicated, s

In testimony whereof we sign this specilication, in the presence of two witnesses, this jolst day of March, 1894.
