GEORGE V. ANDERSON, WILMINGTON, DELAWARE, ASSIGNOR OF SEVEN- SIXTEENTHS TO CHARLES W. GOUERT, OF SAME PLAGE.
MACHINE FOR vSTAKING AND SOFTENING SKINS.
SPECIFICATION forming part:V of Letters Patent No. 380,239, dated March 27, 1888.v v
I Application filed December. 24, 1887. Serial No. 253,892. (No model.) l I v To aZZ whom it may concern:
Beit known that I, GEORGE V. ANDERSON, a citizen of the United States, residing at Wilniington, in the county of New Castle, State of Delaware, have invented a new and useful Improvement in- Machines for Staking and Softening Skins, which improvement vis fully set forth in the following specification and accompanying drawings.
My invention consists of -a machine for staking and softening skins, embodying novel means for operating the clamp which holds the skins while being staked and softened, vnovel construction of the knives, novel means for opening and closing the knives, and novel means for adjusting the pressure of the knives against the skins.
Figure 1 represents a side elevation of a machine for staking and softening skins embodying my invention. Fig. 2 represents a vertical section thereof. Fig. 3 represents a frontl view thereof, partly broken away; and Fig. 4 represents a bottom plan view of one ofthe knives.
Similar letters of reference indicate corre-y sponding parts in the several figures.
Referring to the drawings, A represents the frame of the machine, and 1 the driving-shaft thereof mounted thereon and carrying the pulley 2. On the top of the frame is mounted the counter-shaft 3, carrying a pulley, 4, and cam 5. Passing around the pulleys 2 and 4 is a belt or band, 6, whereby motion is communicated to said cam. The shaft 3 also carries a crank-wheel, 7, to which is attached the rod 8, the lower end whereof has pivoted to it the carriage 9, which is guided in the uprights 10 ofthe frame A. Entering the groove of the cam 5 is a pin, 11,which is secured to the vertical bar 12, the upper endof said bar being slotted to embrace the shaft 3, and the lower end passing freely through the carriage 9. Rising fromthe carriage are supports 13, on which is mounted a horizontally-arranged slide, 14, which is'connected by a rod, 15,with' has a horizontal axis on the support 17 rising from the carriage 9. rlhe lower limb of said lever 16 is slotted, andpassing through the same is a pin, 18, which is connected with the said bar is vertically slotted to permit the of said lower limb of the elbow-lever 16.
K B represents thestationary knife, and Othe movable knife,of the machine, said knives be- 'ing arranged horizontally and projecting to ward each other. The knife B is secured to the standard 19, connected with the carriage 9. The knife Gis secured to the standard 20,0011- nected with the slide 14, whereby said knife C may be moved to and from saidf knife B'. Mounted on the slide 14, and journaled in attachments secured to the standard 20, is a horizontally-arranged rock-shaft,'21, having openings in its ends for the passage of the guiderods 22 of the clamp D of the machine, said clamp consisting of the bar 23, which is secured tot'heswinging frame 24, pivoted or hinged vat its upper ends to the cross-head 25, supportedon the frame A, said frame having opposite to the bar 23 a bed, 26, which constitutes part of the clamp mechanism,"it being noticed that the faces of the bar and bed are tongued and grooved, so that one may enter the other. The bar 23 is connected with the frame 24 by bolts 27 and nuts 28, said bolts being circled by springs 29, which bear against the back of the frame 24 and nuts 30 on saidbolts, whereby the bar of the clamp play .is held properly to its work, and maybe adjusted and ispermitted to yield under eXtraordinary strain. l In the carriage 9 are slots 31, which permit the passage of the ends ofthe guide-rods 22 when said carriage is raised, .it being noticed that the guide-rods depend from the frame 24. The knife B consists of an upper blade, 32, of curved form, and pads 33 below said blade 32. The knife C consists of blades 34 35, both of curved form, the lower blade, 35, being splity or divided `at itscenter and adapted to come between the pads 33 of theknife B, the upper blade, 34, engaging with the blade 32 of said stationary knife B. Y l
lThe operation' is as follows: Powerv is supplied to the shaft 1,whereby the machine is set in motion. A s the clampyD is opened, askin is placed between the bedr 26 and bar 23, and said bar advances, whereby it forces the skin against the bed and firmly holds the saine, it
lower end of the bar 12, it being noticed that' IOO being noticed that the skin depends between the knives B C. Owing to the elevation of the bar 12 and the position of the pin 11 in the groove of the 'cam 5 the bar 12 is now raised, whereby as the elbow-lever 16 is raised by said bar the slide 14 is advanced, and with it the knife C, so that the knives B C grip the opposite sides of the skin. The carriage 9 now descends, and as theknives are held closed together against the sk in the latter is work-ed or staked and softened. When the carriage has made its full descent, the bar 12 is lowered by the cam 5 and pin 11,whereby the elbow-lever 16 is lowered and the slide 14 returned, thus withdrawing the knife C vfrom the skin and releasing the latter. The motion of the slide also withdraws the clamping-bar 23, whereby the skin is released, said withdrawal being accomplished by the action of the slide 14, rockshaft 21, and guide-rods 22, said rock-shaft being connected with the slide, and said rods passing through the rock-shaft and secured to the swinging frame 24. The carriage again rises, and when to its full height the clamp and knives again close on the skin, so that on the next descent of the carriage the skin as held will again be subjected to the staking and softening operations of the knives. Owing to the pads 33, the knives are prevented from beginning the work on the skin with severity, thus avoiding tearing or injuring the same.
In order to adj ust the pressure of the knives on the skin,the rod 15 has the end connected with thc elbow-lever screw-threaded and the same passed through a rock-shaft, 36, whose bearings are on the upper limb of said elbowlever. Fitted on said rod are nuts 37, which occupy positions on opposite sides of the rockshaft 36, and by means of which the throw of the slide 14 may be varied and motion of the knife C consequently adjusted so as to advance to a greater or less extent,thereby regulating the pressure of the knife on the skin. During the motion of the slide and elbow-lever the shaft 36 rocks on its bearings on said lever. The driving-shaft 1 has a power or'fly wheel for evident purposes.
In the operation of dressing skins it is importantto remove the bag,` as it is termed, from the center toward the edges, thus making the skin as nearly level as possible. This is accomplished by my improvement in a reliableand uniform manner.
The lower blade is preferably split or divided, making two blades when that number is required; but a single blade may be employed, the blade or blades in either case being preferably curved,so as not to be injurious in their action.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
