This invention relates to those leather-creasing machines which include two distinct trains of rolls or revolving creases between which the strapor other piece of leather is run; and my improvement consists in providing such machines with a pair ofidler gear-wheels that communicate motion from one train to the other and yet permit a proper shifting or adjustment of either of the trains, so as toadmit thick or thin straps. These idler gear-wheels can'be very conveniently applied to the peculiar forinof leather-creasing machine seen in Letters Patent No. 357,230,. granted to me February 8, 1877-, or they may be fitted to an ordinary creasiugmachine, as hereinafter more fully described, v e
In the annexed drawings, Figure 1 is an end elevation of a leather-creasing machine embodying my improvements. Fig. 2 is a plan ofsaid machine. 4 a y v The end plate or'standard, A, lower shaft, B, lower train of rolls, 0, upper shaft, D, upper train of rolls, E, rock shaft F, swinging arm G, and pin H, being the same in construction and operation as in my patent above referred to, require no further description ,in
Rock-shaft F is pierced near its end to admit a spring-pin, f, that rethis specification;
tains a washer, I, against the face of a master idler-wheeLJ, which wheel revolves freely around said shaft. This master-idler gears with an idler-pinion, K, journaled on a stud shaft, L, that projects horizontally from the standard A. lis a spring-pin that prevents the pinion slipping off the shaft; Idler-pin ion K engages with agear-wheel, M, keyed to the lower shaft, B, which shaft has asquare arboryb, to which the crank N is applied. The upper shaft, D, has a gear-wheel, 0, keyed to it, which wheel engages with the master From the above description it is apparent thatby properly turning the crank N the gear-wheel M,--idler*-pinion K, master-idler J,
o and gear-wheel 0 will revolve in the direction idler J is represented as being considerably twheels may changeposition orbe otherwise the train of rolls 0 Fill such amanner as to drawthe strap in and crease it inthe usual manner. p i 3 It is also apparent that when the front end of arm G is raised to elevate the shaft D pm paratory to admitting a thickstrap between, the rolls the wheel 0 will still remain in-gear with the master idlerJ, and thus insure the proper. action of: thecreasers when the crank is turned. Furthermore, it is evident that when this arm is swung up to the, position" indicated by the dotted line G the gear wheel of the upper rolls will still engage with the master-idlerJ, as. shown by the dotted circleO.
on WYOMING, OHIO, AssIeNoR 0F ONE-HALF To 1 of the arrows seen'in Fig. :1, andthereby turn 55 It, will thus be seen that the upper train of '70 7 rolls is always in a'po'sition to be driven by v the lower train, nomatter how far apart said rolls may be set. -In the drawings the master larger than the other idler-wheel,K, which arrangement is due to the peculiar construction 1 of machine illustrated; but in some cases these disposed to suit circumstances, ortheimprovement may be applied to a-creasing-machine in which the lower roll is swung instead of the upper, also, although not so advantageously, to m'achinesin which the moved 1:911", whether upper or lower, is moved ina straight line instead of an arc. Finally, it is to be understood that the swinging 'arm- G is duplicated at-the otherend of the machine, but theidlerwheels need beapplied-onlyto one end of the rolls. f
I claim as my invention p The combination, in the herein-described leatli'e'ncreasingmachine, of an unadjustable L creasing-roll havinga gear-wheel atoneend, an adjustable creasing roll having a'gearwheel at one end, a rock-shaft arranged longitudinally of the machine, aswinging arm rigidly secured to each end of said rockrshaft, which 7 armscarry the adjustable creasing-roll, and a pair of idler-wheels that co'mmu'nicate motion from one roll-gear to the other, oneiof said idler-wheels being journaled upon-said rock-' shaft, for the purpose set forth,
In testimony whereof I affixniy signature-in presence of two witnesses.
