LEWIS E. LEAROY-D, OF DAN-VERS, MASSACHUSETTS.
LEATHER DRESSING OR FINISHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 484,029, dated October 11, 1892.
Application filed July 16, 1891. Serial No. 399,732. on model.)
To aZZ whom it may concern.
Be it known that I, LEWIS E. LEAROYD, of Danvers, county of Essex, State of Massachusetts, have invented an Improvement in Leather Dressing or Finishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
This invention has for its object to improve the construction of leather dressing or finishing machines.
My invention comprehends a worktable, preferably made adjustable, and one or more dressing or finishing rollers adapted to be moved over the surface of the table, and means for positively rotating said dressing or finishing rollers as they are advanced over the table, and a liquid-containing tank or vessel from which leads a suitable pipe arranged to supply the dressing or finishing rollers with any suitable liquid. The work-table is made to rock, so that first one and then the other end may be raised and lowered A suitable valve is provided for the pipe leading from the liquid-containing tank, which is automatically operated.
Figure 1 shows in side elevation aleather dressing or finishing'machine embodying this invention; Fig. 2,a rear end view of the machine shown in Fig. 1; Fig. 3, a sectional detail of the carriage which supports the dressing or finishing rollers, taken on the dotted line w at, showing one of the rollers in elevation; and Fig. 4., a sectional detail of the dressing or finishing rollers and supporting-carriage therefor.
The main framework comprises a base A and an inclined arm B. A shaft a, having its bearings in the main framework, is driven by a belt-pulley a, thereon and carries a wheel a provided with a wrist-pin b, which is con nected with a slide-block c by a pitman b. The slide-block o is mounted on a guide-rod c, secured to lugs c c on the main framework. A roller-carrying frame It is attachedto the slide-block c by screws 120 or otherwise. A belt-pulley b is secured to the wristpin 1), over which passes the belt 6 which in turn passes over a pulley I), mounted on a Stud 6 which, as herein represented, is a continuation of the stud on the slide-block, to
which the pitman is connected. A sprocket wheel b is secured to said pulley b over which passes a sprocket-chain 22 which engages with and drives two sprocket-wheels b b, secured to shafts b b ,'having their bearings in the roller-carrying frame and carrying dressing or finishing rollers Z9 19 To the opposite end of the shaft 19 another sprocket-wheel b is secured, which is connected bya sprocket-chain 19 with a sprocketwheel Z2 (see dotted lines, Fig. 4,) secured to a shaft I)", also having its bearings in the roller-carrying frame, said shaft b" carrying a dressing or finishing roller 19 It will therefore be understood that the slide block a and roller-carrying frame serve as the carriage which supportsthe dressing or finishing rollers 12 ,19 and 6 and also I desire it to be understood that one or more dressing or finishing rollers may be employed, as desired, although three are herein shown, and, further, that said roller-carrying frame may be detached and any other suitable form of dressing or finishing tool provided.
By means of the crank motion herein shown the carriage supporting the dressing or finishing rollers will be reciprocated over the surface of the work-table d, and also by means of .the belt-pulley b and its connections with said dressing or finishing rollers, the latter will be rotated very rapidly independently of the movement given to them by the carriage, to thereby work into the leather laid on the work-table the dressing, coloringmatter, or other material desired, said rollers acting as calender-rollers.
A liquid-containing tank or vessel 0 is supported in any suitable manner, from which leads a flexible pipe 6, connected to a valvecase e, provided with a delivery-nozzle 6 which is adapted to deliver the liquid material to the dressing or finishing rollers.
The valve-case e is borne by the carriage c, and the valve in said valve-case has an arm a projecting from it, which as the carintegral with or secured to an arm 4 of a bellcrank lever pivoted to the main framework at 5, the opposite arm 6 of said bell-crank lever being connected by a connecting-rod 7 with a hand-lever 8, pivoted to the main framework at 9. When the arm a strikes the pin 3, the Valve is opened and the liquid material will be delivered to the rollers as the carriage is moved in the direction of the arrow. By moving the hand-lever 8 and ment of the arm a the valve. will not be opened as the carriage is reciprocated.
The work-table d is inclined,.'as shown in Fig. 1, or it may be horizontal, and is adjustably arranged on an inclined or horizontal bed 01', as the case may be, which bed issu'pported on independent toggle arms or levers d d at the front and rear ends, said arms or levers being connected to the top side of the base d adapted to be moved Vertically in guide-frames d d and resting on cam-levers These levers d d are pivoted to the guide-frames, as shown, and are connected to a foot-lever d pivoted at 61 to one of the said guide-frames.
By depressing the foot-lever the base-plate (1 may be. raised to raise the inclined tabled vertically.
The toggle-levers d are connected by a se ries of levers with a lever f, pivoted at f, and the toggle-levers d are connected by a series of levers f pivoted at f, said levers ff extending vertically and lying in the path of movement of pins, as12 13, on the wheel a Springs f f are connected to the levers f f and act to normally keep the toggles d and d in perpendicular position or alignment.
As the wheel a revolves in the direction of the arrow thereon the lever f will be moved and the toggle d shortened to drop the front end of the table a short distance, and thereafter the pin 13 will strike the pivoted lever f and shorten the toggle d and dropthe rear end of the work-table a short distance. Hence said table will be made to rock. At such time the table will leave the leather dressing or finishing tool, so that the skin may be moved along.
I do not desire to limit my invention to the particular means herein shown for reciprocating the carriage 0, although the construction shown I deem preferable nor do I desire to limit myself to the particular means herein shown for revolving the dressing or finishing rollers, as it is obvious that they may be revolved by other means; nor do I desire to limit myself to the particular means herein shown for rocking the work-table.
I claim 1. In a leather dressing or finishing ma.- chine, a work-table, supports at its ends, and means, substantially as described, for positively moving said supports independently and alternately to thereby raise and lower-the ends of the table at different times, combined with one or more dressing or finishing tools and means for moving them over the table, substantially as described.
2. In a leather dressing or finishing machine, a work-table, independent movable supports at its ends, and means to positively move said supports independently and at different times to thereby cause the table to rock, combined with one or more rotatable dressing or flnishing tools, means for moving them, and a straight guide, substantially as described. throwing the pin 3 out of the path of move- I 3.

5. In a leather dressing or finishing machine, a work-table, independent toggles at each end supporting it, and a rising and falling base supporting said toggles, combined with pivoted levers, as ff respectively connected I to said toggles, and controlling-springsf f to normally retain said toggles extended, and devices to. turn first one and then the other of said levers on their pivots, substantially as described.
