To all whom it may concern:
Be it known that I, EDWIN B. STIMPSON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Creasing Leather and the like, of which the following is a specification.
My invention relates to an improvement in machines for creasing leather and the like.
The object of the machine is to produce by means of heated creasers permanent markings or creases in leather or other suitable material fed through the machine. Each creasing tool has a plurality of dies thereon of different designs and is rotatable so as to present one or another of said dies at will to the work. The machine further produces any number of parallel creases simulta neously at any desired distance apart. The creasers are also individually adjustable so as to give the desired depths of crease, either all of the same depth or of different depths.
The improved means by which I accomplish the above results are shown in the ac companying drawings, although 1t w1ll be understood that the machine of said drawings is only one of the specific embodiments which my invention is adapted to take.
In these drawings Figure 1 is an end elevation of a machine within my invention; Fig. 2 is a front elevation of the upper part of said machine; Fig. 3 is a detail view on an enlarged scale, said View being taken on the line 3-3 in Fig. 2 looking in the direction of the arrows, and showing parts broken away to receive internal structure; and Fig. 4: is a section on the line H in Fig. 3 looking in the direction of the arrows.
1 designates a suitable machine frame carrying a work-supporting table 2, a driven feed roll 3, and a driving pulley 1. It will be sufficient to state that the pulley 4 is rotatable on a shaft supported by the frame and may be clutched to the shaft at will by means of an ordinary clutch device 5 operated by a lever 6. On the pulley shaft is a pinion 7 (Fig. 1) which gears with a similar pinion 8 on the feed roll 3. With this mechanism, said feed roll 3 is driven at the desired speed. The upper surface of this roll is nearly on a level with the supporting table 2.
The ends of the machine frame have each a pair of horizontal flanges 1 located one ends of the machine frame. has a pair of levers 17 projecting rigidly therefrom ust outside of the respective ends I springs 18.
over the other and having holes therein which are in vertical alinement to receive with sliding bearing fit a rod 12, one at each end of the machine. Adjustable collars 13 on these rods prevent them from dropping through these holes 1n the flanges by bearing against the upper side of the lower flanges. 141t are compression spiral springs on the rods between the upper flanges and said collars serving to keep the rods normally depressed.
11 is the vertically movable head of the machine and is connected at its ends to the rods 12. This head supports the creasing tools operatively over the feed roll 3.
The aforesaid springs 14 serve to depress the head 11 and its creasing tools against the work, vice versa, said parts are elevated by steppmg on the foot lever or treadle 15. This treadle is rigid at its rear .end with a long rock shaft 16 having its bearings in the This rock shaft of the machine frame. The free ends of these levers are connected to points above them on the ends of the frame by tension 202O (Figs. 1 and 2) are connecting rods which operatively connect the levers 17 with the horizontally disposed levers 21, which latter tilt about the pins 22 on the ends of the frame. The forward ends of these levers are semi-circular and at their extremities have horizontally disposed round studs or pins 23 which extend under the projecting ledges 2 f constituting the ends of the creaser supporting head 11.
The result of the devices thus far de' scribed is that when the operator steps on the treadle 15, he elevates simultaneously the curved or forward ends of the tilting levers 21, and consequently elevates simultaneously from both ends the head 11. This permits the operator to feed the leather under the This having been done, he removes his foot from the treadle and the heavy springs 14 carry and hold the creasers down to their work. The tension springs 18 are relatively weak and merely serve to uphold the treadle 15 and the related parts in a normal position. The adjustable bolts 19 in the levers 17 prevent these springs 18 from lifting the treadle too high by striking against the bottom of the lower cross-pieces of the ends of the machine frame. Each creasing device consists of a body portion 30 (Fig. 1) having a dove-tail slot in its top which receives endwise through it the dovetailed lower edge 11 of the machine head 11. It will be noted from Fig. 1 that the ends of the machine frame are open so that the creasing devices can be passed through said ends to insert or remove them from the clovetail portion of the machine head.
Fig. 2 shows graduations on the front of the head 11 to permit the operator to adjust the positions of the creasing devices along the head accurately as desired. To lock the individual creasing devices in their adjusted positions against endwise displacement along the head 11, each has a handle 31 pivoted between a pair of lugs 60 (Figs. 2 and 3) extending from the body portion above the front incline of the dove-tail 11 the pivoted end of said handle having a cam surface 33 which binds against said incline when the handle is pressed down as in Fig. 3 but which does not bind against it when the handle is pressed up. The body portion 30 has a pair of spaced apart forwardly and downwardly extending legs 34L (Figs. 1 and 3) connected at their base by pivot pin 41 and at their ends by a pivot pin 35.
is a hook (Fig. 3) rigid with the rotatable pin 1-1 between these legs 3%, and 12 is an operating handle at the right hand side of each creasing device in Fig. 2, (also compare Fig. 3) said handle being rigid with the end of this same pin 41.
36 is a U-shaped member for supporting the actual creasing tool. The front leg 36 of this member is pivotally connected to the body portion 30 by the pin 35 on which it is supported between the legs 34.
38 is an adjustment screw supported at the upper end of the front leg 36 to bear against the front of the body portion 30, and this screw has a lock nut 39 for use in maintaining the desired adjustment of the screw. The upper end of the rear leg 36 of this U-shaped member is connected by the coiled tension spring 37 with a part of the body portion 30 below it. This tension spring has the effect (compare Fig. 3) of pivoting the U-shaped member about the pin 35 to force the creasing tool which it supports yieldingly against and into the work L. The actual creasing tool may take the form shown consisting of a disk (Figs. 3 and i) rotatably supported on a pin or axle 50 between the bifurcated bottom por tion 36 of the U-shaped member. This disk has a plurality of creasing dies 51 around its periphery.
52 are ratchet teeth on the side of the disk and 53 is a spring pawl projecting from the U-shaped member into a position to engage said teeth. be rotated in anti-clockwise direction to bring any desired die 51 in operating position, but prevents said disk from being ro- This pawl permits the disk to tated by the passage of the work L through the machine by the feed roll 3 (Fig.
61 is a gas pipe leading from the main supply pipe 62 to deliver gas to a burner located adjacent each disk 50.
The previously described hook lO, by pressing down on the handle 1-2, is adapted to hook under a pin 4L3 which connects the sides of the bifurcated bottom portion 36 of the U-shaped member. The result is that the entire U-sha ed member and its creasing tool or disk are pivoted upwardly about the pin 35 into a non-operating position out of contact with the work, so that the disk 50 can be rotated as previously described or so that the entire creasing device can be slid .idwise off the dove-tailed supporting edge 11 of the machine head, or so that any of the creasing devices can be merely allowed to hang idly from said head. The tension of the spring 37 in each creasing device assists in giving the requisite creasing pressure to the die. On the other hand, the adjustment of the set screw 38 determines the depth to which the spring shall force the die into the surface of the work.
Of course, it will be understood that changes in construction may be made in the devices of the drawings without departing from the spirit and scope of the invention, and these are intended to be covered hereby.
What I claim is:
