To all whom it may concern,.-` i

Be it known that I, LEOPOLD BAUMEISTER, a citizen of the Grand Duchy of Baden, residing at Bridgeport, in the county of Fairfieldv and State of Connecticut, have invented certain new and useful Improvements in Machines for Polishing Wire; 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.

My invention has for its general object to produce a machine that will perfectly polish all qualities and shapes of wire, from the coarsest to the finest, either before or after it is tempered.

With these ends in view I have devised the simple and novel construction of which the following description, in connection with the accompanying drawings, lis a specification, numbers being used to denote the several parts.

Figure 1 isa plan view of the entire machine, the covers of the emery-boxes being removed; Fig. 2, a longitudinal section on the line .fr a: in Fig. 1; Fig. 3, an enlarged cross-section on the line y y in Fig. 1, looking toward the left; Fig. 4, an enlarged cross-section on the lineazin Fig..1; Fig. 5, an enlarged crosssection of one of the boxes; Fig. 6, a detail sectional view illustrating the construction of one longitudinal section corresponding with Fig. 2, showing the carriage arranged to swing instead of slide.

1 denotes the frame-work, which may be of any preferred construction; 2, tension devices at the front of the machine regulatedby screws 3; 4, winding-drums at the rear of the machine, Land 5 a reciprocating carriage at the central portion thereof. Upon each side of the carriage is an cmery-box, 6, through which a strand of wire (denoted by 7)` is passed to polish it. It will of course be apparent that any number of these boxes may be provided in each machine. In the present instance I have shown two, that being the number ordinarily used.

The construction and operation of the parts of the machine upon the carriage constitute an important part of my invention, which I will now proceed to describe in detail.

Each vbox is provided with upper and lower sets of polishing-rolls, (designated,respectively, as 8 and 9.) The rolls in either or both of the sets may be made adjustable. In practice I ordinarily make the lower set stationary and the upper set adjustable, and have so illustrated the construction in the drawings. The

lower rolls are carried by shafts 10, which are journaled in the sides yof the boxes, stumps 11 being cast upon the sides of the boxes to increase thebearing-surface and strengthen the machine. The outer ends ofthese shafts are squared, and gears 12 are placed upon the squared portions, as is clearly shown in Fig. 6, this portion of the arrangement of both upper and lower rolls being identical. These rolls may be made of any suitable material--l for example, wood, leather, lead, o r felt. For ordinary iiat wire I, preferably use a number of thicknesses of heavy felt, which are slipped over enlargements on shaft 10, and are held firmly in position bywashers 13 and screws 14, engaging the inner ends of the shafts. In

order to preventl emery in the boxes `from working into the bearings of shafts 10, I pro-` vide collars 15 upon said shafts, which tclosely in corresponding recesses in the sides of the boxes, and leather washers 16 between r the feit' and the sides of. the boxes. The screw and washer at the other end of the roller act to press the felt or other material firmly againstv the' leather washer, which, in connection with the collar, prevents the entrance of any emery whatever into the bearings. Theupper' rollers are constructed in precisely the same manner, but vthe shafts 10 Vare journaled in slides 17, having stumps 18. These slides have vertical movement in corresponding grooves in the sides of the boxes. (See Fig. ll.)

Any number of rolls may of course be used in each set. shown four rolls in the under set and three in In the present instance I have' the upper set. The stumps and slides yin which porting-pieces 20by screws 21, passing through Y slots 22'* in the sides of the boxes'. Both supporting-pieces are provided with lugs 23, and set-screws 24, passing through these lugs, en-

gage the top and bottom ofthe side of the motion may be imparted to the carriage in any suitable manner.

In Figs. 1, 2, and 3 I have shown the carriage provided with rollers 25, which travel upon tracks 26, and are held in position by strips 27, said tracks and strips being fixed to the frame-work in any suitable manner; and in Fig. 7 I have shown the carriage supported by oscillating levers 28. Y

29 denotes the main shaft of the machine, to which power is applied by a belt, (not shown,) and 30 denotes a crank, which may be upon the main shaft, as in Fig.'7, or upon a secondary shaft, yas in Figs. 1 and 2, in which the main shaft is shown as provided with a pinion, 31, and the secondary shaft with a gearwheel, 32, meshing therewith.

30"l is a link connecting the crank with the oscillating lever.

In Figs. 1, 2, and 3 but a single oscillating lever is used, which is pivoted to the frarnework. At the upper end of this lever is a yoke, 33, and 34 is a sliding block carried by the yoke. A cross-piece, 36, having arms 35, holds the block in position in the yoke.

37 denotes cross-bolts which extend through both emery-boxes and entirely across the carriage from side to side. One of these bolts passes through sliding block 34, whereby the oscillations of lever 28 are caused to impart reciprocatory motion to the carriage.

In order to insure continuous change of the polishingsurface of rolls 8 and 9 upon the wire, I cause a partial rotation to be imparted to each of the polishing-rolls at each reciprocation of the carriage. This may of course be accomplished in any suitable manner.A In the present instance I provide endless chains 38, which engage all of the gears 12 upon the shaft of the rolls in each emery-box, passing over and under alternate lower and upper gears. Upon one of the lower shafts in each emery box I provide a ratchet, 39, -keyed thereto.

40 is a lever which turns on said shaft, and is provided with a pawl, 4l, which engages the ratchet. A link, 42, connects each pawl-lever with one of the arms 35, which project from cross-piece 36. It will be seen that each time the carriage moves toward the right pawls 41 are moved backward over one or two teeth on ratchets 39, and when the carriage is moved toward the left this movement must carry the ratchets forward an equal distance, and, through their shafts and the endless chains which engage all of the gears 12 belonging to each emery-box, impart a corresponding ro tary movement to each of the polishing-rolls, so that a fresh polishing-surface comes in con tact with the wire at each reci procation of the carriage.

It will of course be understood that the emery-boxes are covered, so that it is impossible for the contents to iiy out, and, as already described, I have so constructed the parts that it is impossible for emery to work into the bearings. Even if emery should fly out from the boxes it could not come in contact with any of the operative parts of the machine, but would drop upon the floor. When it is necessary to put in new polishingfrolls, it is simply required to remove the outer sides (denoted by of the emery-boxes and remove gears 12 from shafts 10, when the latter may be readily drawn out and the rolls removed.

The tension devices (denoted by 2) at the front of the machine require no description, as any ordinary or preferred devices of this class may be used.

The winding-drums are carried by a shaft, 43, at the opposite end of the machine. 44

denotes switch threads or worms mounted on this shaft, and 45 travelers mounted on arms 46, projecting from the framework. These travelers engage the switch-threads and cause longitudinally-reciprocating movement to the shaft,` so that the wire is wound evenly upon the drums. The rotary movement of the drums is imparted from lever 28 by means of a pawl, 47, which engages a ratchet, 48, on shaft 43. In Fig. 2 this pawl is carried by a bell-crank lever, 49, pivoted to the framework, and connected by an adjustable link, 50, to oscillating lever 28.

5l is a weight acting to hold the pawl in engagement with the ratchet. It will be seen that each movement of the oscillating lever toward the right will draw the upper arm of the bell-crank lever downward, and consequently draw the pawl backward over the ratchet, while the return movement of the oscillating lever will raise the upper arm of the bell-crank lever, and with it the pawl, forcing the ratchet forward and imparting a rotary movement to the drums. In Fig. 7 the pawl is carried by a lever, 52, the opposite end of which is provided with an incline, which is engaged by a roller, 53, on one of the oscillating levers. A spring, 54, acts .to draw the forward end of the lever downward and hold the pawl in engagement with the ratchet.

55, in both forms, is a pawl which engages the ratchet and acts to hold it against back ward movement. The operation is the same as in the other form. It will of course be apparent that the slower the wire is wound upon the drums the more times the polishingmolls will pass over its surface. The amount wound at each reciprocation of the carriage may be readily adjusted by moving the point of attachment of link 50 to the oscillating lever up or down, in the form illustrated in Fig. 2, or by moving roller 53 up or down, in the form illustrated in Fig. 7. In practice I usually wind about four inches of polished wire IOO IIO

IOl

380.162 Y g w at each reciprocation of the carriage. In order to reduce the wearupon the rolls to the minimum, I provide an adjustable guide, 56, at the front of each emery-box, having an aperture, 57, of suitable size and shape to permit the wire to pass through it freely, butl at the same time to hold it against lateral movement. As the machine is shown' as acting upon a flat wire, the guide illustrated is shown as provided with a corresponding aperture.

- 58 denotes set-screws passing through slots in the guide, whereby it is locked in any desired position.

Each time a new coil of wire is placed in the machine to be cleaned and polished guide 56 is moved so that the wire comes in contact with an unused portion of the surface of the polishing-rolls.

The operation of the entire machine has been so thoroughly described in detail as to require but a brief recapitnlation.4 In starting the machine the strands of wire are passed through thetension devices, then through the emeryboxes between the upper and under sets of polishing-rolls, and the ends are attached to the winding-drums. Theboxes are filled with emery, and the pressure of the polishing-rolls. upon the wire is then adjusted, and the machine is ready for the application of power.' In use the carriage lreciprocates backward and forward, causing the wirev to be thoroughly cleaned and polished by the action of the emery and the rolls between which it passes. The rolls have no movement, except as actuated inthe manner described for the purpose of continually changing the surface that is acting upon the wire. The movement of the carriage is sufficient, so that several movements of the polishing-rolls take place over each portion of the surface of the wire. A

The machine is adaptedfor all sizes, shapes, and qualities of wire, and is found in practice to perfectly removea heavy oil-scale after tempering, and to impart to the wire a perfect polish.

It will of course be understood that the details of construction are subject to almost unlimited variation without departing from the principle of my invention.
