OTTO CZARAN, OF LONG ISLAND CITY, NEW YORK.
APPARATU FOR MAKING- BELTING.
Application filed January 28, 1919.
1 0 aZZ "Ml/b07711 may concern Be it known that OTTO CZARAN, subject of Austria Hungary, and resident of Long Island City, in the county of Queens and State of New York, has invented certain new and useful Improvements in an Apparatus for Making Belting, of which the following is a specification.
The present invention relates to belting and particularly to the making of light belt ing such as is used for driving sewing machines and such other light machinery.
The object of my invention is to provide apparatus for making such belting from a side of leather, the apparatus being so arranged and embodying such means as to continuously feed the material in at the fore end of the machine and pay the same out at the rear end in the form of finished belting of desired cross-section, smoothened, hardened and polished.
My invention embodies means for cutting the leather strip into a predetermined width to form a strip square in cross-section, means for shaping this into a belt of circular or other desired cross -section, means for stretching the belt when finished from stretching unduly under strain; means for smoothening, hardening and polishing said belt, and means for winding the finished belt on a spool removable from the machine and from which it may be paid out in desired lengths.
Referring to the drawings which form a part of this specification,
Fig. 1 is a plan view of a machine embody ing my invention and showing a table upon which are mounted the specific devices for performing the several operations required in making the round belt and preferred means for driving said mechanism.
Fig. 2 is a side elevation of the structure illustrated in Fig. 1 and partly in longitudinal section.
Fig. 3 is a longitudinal view partly in section illustrating a construction for holding the disc of leather while it is rotated between a pair of rollers prior by the dividing knife and referred to in Fig. 1 by line 38.
Fig; 4 is a cross-sectional view set line 44 of Fig. 2.
Fig. ,5 is a cross-sectional of the offview on line to being cut Serial No. 278,648.
5-5 of Fig. 2 disclosing the removable sp'ool in longitudinal section.
Fig. 6 is a detailed vertical sectional View on line 6-6 of Fig. 1 showing the means whereby the roller which is held to permit of lateral adjustment to provide for cutting the belt to a desired width.
Referring in detail to the drawing, A indicates a table made preferably of cast iron upon which are mounted rollers A, A, A, upon which is placed a disc of leather from which the belt is to be formed. 13 and B indicate two rolls, the lo er one B, of which is driven from the countershaft C through the miter gearing G and the edge of the leather disc is held between the said rolls and propelled thereby against the knife D which cuts it to the proper width, said width being determined by the position of the rolls D, Das will hereinafter more fully appear. The upper roll B is held in a frame B which in turn is journaled on the pins B B which have their bearings in the outer frame 13 which in turn is held on one end of the lever B and is pressed toward the roll B by the spring 13 as will be readily understood. This construction permits the leather disc to be firmly held and propelled by the roller B and is made to conform to the variations in the thickness of the leather and in case the leather is uneven or warped, to force the same into sure contact. After the strip has been cut by the knife 1) it passes between two pairs of guide rolls, E, E, disposed in planes trans verse to each other, to the cutting knife or trimmer F consisting of a conically formed tube, the small periphery of which is sharpened to provide a circular cutting edge to round the square belt strip into circular crosssection. The top rolls of the rolls. i P) are also provided with a spring F/ for tensioning them against the lower rolls. The belt then passes between the glOOVECl rollers G, G, which are held closely together by a spring G located in the lionsing r and is then led between the rollers H, H. which are submerged in an oil bath I and thence between the rollers J, J, and K, K, and into the spool L on which it is wound in successive layers and may. beremoved at this point if however, the spool L servesto pull the belt desired. Ordinarilv.
- disconnect shafts through, the latter being wound several turns thereon and being driven through the l the belt is drawn shaft C and gearing through by the spool L as it is being cut and shaped. The belt is then carried over the spool M and between the rollers m, m, to the friction wheels, N N, and polishing wheels N, h, respectively. faces are the polishing wheels are covered with raw hide or other suitable material to polish the surface of the round belt by friction. The friction wheels N, N, are driven at a high speed and serve to smooth and harden the surface of the belting. These sets of fiction and polishing wheels are driven from the shaft 6 through the gearing O, and the first set of polishing rolls is driven by means of the belt P and gearing P. The wheels N, N are mounted on shafts N N respectively, supported in standards N N and the polishing wheels N N are held in a housing N. The belt then is passed successively between the rollers R, R, S, S, T, T, and U, U and on to the spool driven through the miter gearing N which is driven from the ft as will be clear from the drawing Clutch means X, X are provided to connect and C and O respectively from the main driving shaft Y.
The kni e D is held in bracket D which bracket also supports one of the rollers and said roller and knife D are therefore adjustable with the bracket and held in ad justed relation by the screws ll passing through the slot D formed in the uiaclret.
The rollers D. D and the roller held by the bracket E are adjustable to and from the strip of leather which to be formed and the adjusting means consist of a plurality of wedge members (Z which clamp the end of the journal (Z firmly in any desired lateral adjustment.
Mounted on the table A is a which is adjustable longitudinally of table by reason of the slots (1 and held in. adjusted position by bolts Z), I), 0, indicates a drum having a continuous cam groove e formed therein. is an arm f one end of which is pivoted on the bracket as at c while the other end car ries the guide pulleys K, K which are made to swing in the arc of a circle by the travel of the arm in. the groove 0 by means of a stud i secured. to the arm f and free to slide in the slot f formed in the arm The drum in turn is driven from the worm gear 7.1 which by reason of its slow transmission moves the bracket a the the pulley to be swung back and forth to wind the belt on the spool ll in successive layers, if desired. Ordinarily. however, the stud i is removed and the belt permitted afterhaving' a. few turns taken on the spool to continue on to the spool M and thence to The contact sur Mounted on the bracket a.
drum slowly and in turn causes the polishing rolls. By a longitudinal adjustment of the bracket a the are through which the pulley K, K swings may be varied within limits to accommodate belts of different diameter to be carried back and forth the entire length of the spool. For large variations the gearing may be changed as will be readily understood. hen winding the belt after polishing on the removable spool L a similar drum n and like cam mechanism as just described is employed. The guide rolls H H are carried on the lower end of a rod H. the arm and which is free to slide in a guide formed in the casting H secured on the underside of the arm 7" and the belt can be placed under any required tension by means of the lever H and held. in the adjusted position by means of the bracket ll also carried by the arm f. As the arm swings back and forth the rolls H, H also swing back and forth through the bath. The rolls J, J are slidably mounted on shafts extending across the bed A. to the width substantially of the bath to permit the belt to remain in alignment when leaving the rolls H, H and passing to the rolls K, K. I preferably use a bath of oil but may use any other suitable fluid.
The detailed construction of the removable spool is illustrated in Fig. 5, in which L represents the spool and h, hindicate flanges which carry pins it, h to engage corresponding openings in the flanges of the spool. A bolt 72/ extends through an opening 71- formed in one of said flanges and screws into the tapped socket h of the opposite fiange. So that. by removing said bolt 71. and sliding, the right hand flange it can be moved in the bearing 7L5 a distance corresponding to the length of twice the length of the pins it, thus freeing the spool as will be readily understood.
It brake is provided to prevent the reel M from unwinding except as the belt is drawn to the polishing rolls. this consists of a belt r, one end of which is held to a post a and the other end of which carries a weight 1'. the friction of the belt preventing the reel from unwinding except as the belt is withdrawn therefrom.
