PUTTING-OUT ivlACl-HNE.
SPECIFICATION forming part of Letters Patent No. 310,279, dated January 6, 1885. Application filed Sei temeer 16, 1854. (No model.)
To @U 1l/tem may concern:
Beit known that I, WILLIAM M. Horrimiv, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New 5 York, have invented certain new and useful Improvements in PuttingOut Machines, of which the following' is a specification.
The object of my invention is to provide a new and effective means for striking out and i@ putting out the grain, soas to remove the Water and other imperfections from calf or other skins.
It is well known that a skin, after being raken from the tanning-vath previous to being fully tanned, is put through a process usually calle( striking-out.7 This process stretches the skin and removes the grain and other imperfections therefrom. The object of this first operation or strikingout is to make the tan- Qo ning process more rapid, and to stretch the skin to its full length or size. The skin is now returned to the tanning-vat and fully tanned, and then taken out of the vat and put through the first process again. It is then Q5 colored, after which, and previous to being hung up to dry, it is put through a process termed putting-out, which renders the grain side of the skin smooth and removes all imperfections from the flesh side.
3o The construction and operation of my invention will be fully and clearly hereinafter shown and described, by reference to the accompanying drawings, in which- Figure l is a front elevation, Fig. 2, a plan or top View. Fig. 3 represent-s a side elevation, taken from the driving-pulley side of the machine, and Fig. 4 is a vertical section through line .e fr, Fig. l, the gear-wheels being left off.
4o The frame a of thc machine may be constructed either of cast-iron or wood. a is the putting-out cylinder. It is provided with the usual spiral blades, ai. The putting-out cylinder is usually constructed ot' wood, and
4 5 the spiral blades of brass. It is provided with a central shaft, a, of iron or other suitable material, and is journaled in two arms, a, in boxes ai. The arms a are secured loosely to the driving-shaft b, which shaft is mounted in 5o boxes b.
On the driving-'pulley side of the machine is a gear-wheel, b, keyed or otherwise securely fastened to the shaft b. This gear- I wheel b gears into the pinion Zl on the put- 55 l ting-out-cylinder shaft and gives it the required movement. At the opposite end of the main shaft is a pinion, Z1, which engages .with the spur-wheel c, which is secured to a shaft, d. 1 Fitted in bearings ci c (see Fig. 2) at the l outer end of the shaft c' is a bevel gear-wheel,
l c, which gears into a bevel gear-wheel, The gear-wheel ci is rigidly secured to a shaft,
d, which shaft is mounted in bearings d d2, the bearings being on brackets or supports secured in any well-known way to the side frame. N ear the opposite end of the shaft d is a bevel-pinion, d, which gears into a bevel gear-wheel, d. This wheel d* is keyed or oth- 7o erwise secured to the shaft d5 of the lower feed roller, c.
e is the upper feed-roller.
To the arms u is jointed, to each, an arm, c2 c, by joints e* e, having their opposite ends 7 5 jointed to the treadle f by joints ff". The treadle-levers f3 are secured to a shaft, f 0, and each extends backward, so as to receive a counter-weight, In front of each of the teeding-rollers is a cleaning-roller or rotary 8o brush, g y, receiving their movement from the gearing r/4 g5,- but their movements may be given by belts and pulleys arranged in any suitable or well-known way. Y
In operating the machine the skin is thrown over the upper feedroller, d, over which it passes until it is caught in rollers e and e. A pressure on the foot-step then brings the putting-out cylinder against the skin, which cylinder is made to revolve rapidly,'(about six 9o hundred revolutions per minute, while the feed-rollers make about eighteen turns per minuta) and cleans oft" the small pieces of flesh or other matter adhering to the skin, and stretches'the same both ways, taking ont the 95 wrinkles or other imperfections, so as to leave it smooth and clear. This operation finishes one-half of the skin, which is then taken out, and the opposite end treated in the same manner, so as to complete it.
f b2 is the drivingpulley.
