Be it known that I, JAMEs-D. RANDALL,

of America,

of Hamilton and State of Ohio, have invented a new 'and useful Improvement in a Belt Finisher, of which the following is a specification'.

An object of my invention is to provide a device adapted to smoothly round the edges of beltsy and to color, burnish and enamel the rounded edges after their formation. Y.

Another object is to provide a device for the purpose stated that is simple in construction and operation and -that will do the specified work with the maximum efliciency.

These and other Vobjects are attained by the means describedl hereinandl disclosed in the accompanying drawings, in which'- l is a plan view o-f a deviceembodyf ing my invention.

My invention comprises a table over which belts are moved longitudinally of their length and suitable cutters, brushes and burnishers adapted to operate upon the plan view of the mechanism to actu'ate the belts .and the mechanisms operative thereupon.

The table or lbase A is preferably supported by suitable legs or uprghts, or as I have shown, by means of the depending flanges a so that the upper or top surface a thereof is disposed in a horizontal plane. The table is preferably rectangular and has formed in its top two parallel series of depressions, or recesses, a2, a3, a4, a5, a6 andv a7, extending longitudinally thereof.` guide or way extends longitudinally of the table intermediate the two parallel series of depressions, the table and a long-flat cover plate a8 mounted upon the brackets a disposed at each edgeV of the way and which brackets together with the cover plate, are secured upon the table by means of screws am.I The upper surface of the table functions as` the'bottoin of this guide or way. The sides of the. way are open flanges a.

of vertically alignedl transverse slots are formed in thev cover plate and the table. Ihe belts pass through .the guide or way, and a series of feed rollers a extend into the transverse slots and feed the belts through theguide..y The rollers are disposed in vertically aligned pairs, the lower of which are mounted on` the transverse feed shafts a mounted upon thedepending The shafts an have lmounted upon lthem the bevel gears a bevel gears a14 or auxiliaryv drive shafta15 the brackets al extending from 'the `side of the table.

transverse or main drive shaftu?7 suitable means such" as the worm'ct1s and the worm wheel al@ The main drive shaft is driven by any suitable means such as al suitable pulley-u20 and a suitable sourceof energy, p not shown. Above each ofthe lower feed rolls is mounted a second or upper lfeed roller having its bearings in the blocks ad? slidably mounted between pairs of vertical standards4 @22. yAlin'k L23 is mounted atop each pair ofv standards,

and a coil s rin@ L24 .is Lmounted intermediate the link and-the block mounted on .j each pair of the standards.` .The springs,

retain lthe upper feed roller. in yielding engagement upon the lower feed roller. The .upper feed rollers mayy be driven by engaging the mounted on the longitudinal mounted upon The `shaft L15 is driven from. by anyA means of the gear c25 mounted on the `forward transverse shaft al? mounted near the front or forwardA endl of the y. table, and which gear meshes with the` gear y Q26 mounted on the shaft supporting the upper feed roller of the firstV or forward pair'of feed rollers. I find thatsatisfactory results are. attained by positively driving the lower feed roller of each pair. and thenone upper feed roller of the first pairof feed rollers.

The edge rounding mechanismfB comprises suitable abraiding wheels or, las I have shown, a' pair of circular k or-fdisk cutters or knives Z), of which one is mountedI in each of the depressions a? and entendsl partly therefrom. is pivotally and adjustably mounted'onr the under surface of the table by; any suitable means such as the bolt. 52' adjustably .en-v gaging the table vand the set` screw '1.53

adapted to "lock the bolt in an adjustedk A suitable bracket t position. lf desired, suitable shims b4 may be employed to space the bracket from the table. The bracket has mounted upon it the revoluble vertical shaft the upper end of Which lies within the depression a2 and has mounted upon it the cutting disks b. A pulley 5G is `mounted on the lower end of the shaft b5( The shaft is mounted on suitable ball bearings 57. l pin ZPS is adjustably mounted on the depending flange a and a spring b9 extending between the bracket b and the flange a, yieldingly re- .tains the bracket in engagement with the pin bs. The means described permit adjustment of thev cutting disks vertically and horizontally in relation to the guide or Way on the table. The cutting` disks have preferably a central circumferential groove having the shape that is to be given the edge of the belt.

The inking or colori-ng mechanism C comprises the sleeves c and c having formed Within them vertical bores Within which boresy are revolubly mounted the shafts c2 and 03 respectively. rThe sleeves c and c are mounted upon the under surface of the table by any suitable means such as by forming lugs c4 upon the sleeves and through which lugs the bolts c extend. rlhe shafts c2 and c3 extend into the depression a3 and have mounted upon their upper ends the inlring brushes c6 and c7, to which ink is fed from a suitable container o8 mounted upon the side of the table and having a suitable feed pipe 09 With a valve 010 therein, the feed pipe and valve being adapted to direct and control the flow of ink from the container cs to the brushes. The brushes are preferably made of bristles which interengage, as shown in Fig. 1. The shafts c2 and o3 have mounted upon their lower ends the spiral lgears c11` and 012 respectively, which engage the spiral gear 013 mounted upon the shaft c, mounted transversely of the table and'belovv the upper surface thereof. The shaft 014' has mounted upon it the sprocket Wheel c15 which is driven by means of the chain 016. A pair of brushes as just described, is mounted on each side of the longitudinal Way formed over the table.

rlhe burnishing mechanism D comprises the burnishing Wheels l of Which there are three mounted on each side of the Way formed upon the table, one each of such Wheels being disposed Within the depressions at, a and a6. Each of the burnishing Wheels is mounted at the upper end of a shaft 0l revolubly contained Within a sleeve d2; rThe sleeve d2 has a flange Z3 formed adjacent its upper end, which flange is secured upon the under surface of the table by means of suitable blocks it and bolts d5. The blocks d4 and bolts (Z5 are mounted upon the flanges am formed on the under surface of the table. Sufficient play is provided between the flanges L27 and da to permit any desired horizontal adjustment of the burnishing Wheels as shown in Fig. The pulleys d, 7, d8, (Z9, d1", and d are mounted upon the lower ends of the shafts d', the driving of Which Will .be explained hereafter.

The enameling mechanism E comprises a sleeve e mounted upon the under surface of the table and revolubly mounting the vertical shaft'e, the upper end of which shaft extends into the depression 0,7 and has mounted on it a brush c2, and upon the lower end of which shaft is mounted a spiral gear e3. The sleeve e may be mounted upon the table in any suitable manner, such as by means of the lugs cAk formed upon the sleeve and through Which the bolts e5 extend. rllhe bolts c secure the sleeve upon the table. The slots in the lugs through Which the bolts c extend, may be elongated to permit adjustment of the sleeve. A suitable container e for the supply of enamel is mounted upon the side of the table and the enamel is fed therefrom to the brush e by means of a suitable pipe e7. The spiral gear e3 mounted at the lower end of the shaft e2 meshes With a spiral gear e8 mounted on the shaft e9, mounted below the table transversely thereof. A sprocket Wheel 61 is mounted upon the shaft e9 and engages the chain o16. A. Worm Wheel e is mounted upon the shaft e9 and engages the Worm cl2 mounted upon the longitudinal drive shaft @15. rlhe sleeves c and c may be mounted upon the table in the same manner in which sleeve e is mounted in'order to pern mit horizontal adjustment of said sleeves.

Motion is imparted to the shafts b5 and d as follows:

`The main drive shaft a has mounted upon it, on opposite sides of the pulley (L20, the pulleys @28 and w29 having the same diameters. A. belt f extends about the pulley L23 and about the pulley as@ mounted adjacent to the pulley d10 upon one of the shafts d. rlhe belt f extends about the pulley 0:29 and about the pulley @31, mounted adjacent the pulley Z9 on a second shaft d. A belt f2 extends about the pulley dg, one of the pulleys b mounted upon one of the shafts b5, about the pulley d8 and about the second pulley 5G' mounted on the second shaft fr, and then returns to the pulley dg. A belt f3 extends about the pulley d10, the pulleyd, the pulley du and pulley d?. The pulleys d, 7, ds, dg, d10 and di are preferably of the same diameter', therefore the burnishing Wheels l Will revolve at the same rates of speed. The burnishing Wheels have a circumferentialr groove d, into which the belts extendas they pass through the Way. rlhis groove is substantially the same as the circumferential grooves in the cutting disks. The several shafts supporting the cutting disks, the brushes and the burnishing wheels, I

revolve in the directions indicated by the arrows in Fig. l.

A casing H is mounted over the cutting disks and has a fan 72, mounted at one end thereof adapted to withdraw the cuttings 'from the mechanism B and to discharge the yarrow in Fig. 2. The shaft al? is mounted at the rear end of the table. A belt G is fed into the way at the front end thereof, and the first pair of feed rollersv grasp the belt and feed the same through the way. The feed rollers have motion imparted to them from the shaft 0515. As the belt ed es are exposed lto the cutting disks, t e edges of the belt are trimmed 0r rounded in accordance with the shape given to the cutting tool. The cuttings from the belt are withdrawn through the casing H by means of the exhaust fan It. The belt then passes beneath the second pair of feed rollers and then passes between the inking brushes 06 and 07, at which time the edges that have been worked upon by the cutting disks are inked. The belt then passles under a third pair of feed rollers, and

immediately thereafteris acted upon by two pair of the burnishing wheels al, which burnishing wheels are revolved at a high rate of speed in a direction such that the surfaces of the burnishing wheels engaging the belt edges, move in a direction opposite to the line of movement of the belt through the way, the friction resulting therefrom serving to dry the ink with which the beltedges are colored. The belt then passes between a fourth pair of feed rollers and isthen subjected to a third pair of burnishing wheels moving in the same direction as the preceding burnishing wheels. The fourth pair of feed rollers isy interposed between the 'third pair of burnishing wheels vand the second pair ofburnishing wheels solely to provide a smooth and leven feed of the belt` through the way. If desired a larger nuinber of burnishers and feed rolls may be em-l ployed. From the last burnishing wheel the belt passes to the enameling mechanism Where the brushes e2 enamel the side edges j of the belt. As the belt leaves the rear end of the way, the finishing of the side edges of the belt has been completed.

What I claim is:

In a belt trimming device the combination A of a table having a way formed in it, means to feed belts thru the way, and belt trimming mechanisms extending into the way and 'comprising a bracket, a bolt vertically adjustable on the table pivotally the bracket, a -bracket having formed on it, a revoluble shaft carried by the bearing, a cutter carried by the revolubl'e shaft extending into the way, a pin adjustably mounted on the table engaging the bracket for'moving the cutter into the way,

supporting and a spring extending between the bracket and the table yieldingly resisting movement of the cutter into the way.

In testimony whereof, I have hereunto subscribed my name this 3rd day of June,

JAMES D. RANDALL.
