GEORGE S. HERRICK AND CHARLES J. HERBICK, OF SYRACUSE, NEW YORK.

WILLOW-STRIPPING MACHINE.

To all whom it may concern:

Be it known that we, GEORGE S. HERRIOK and CHARLES J. HERRIOK, citizens of the United States, and residents of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Willow-Stripping Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and eXact description.

This invention relates to machines which are designed to remove the bark from willows whereby said willows may be woven into baskets and other articles, and it has special reference to the class of machines embodying a pair of parallel traveling belts beween which the willows are passed by means of a suitable feeding device, said belts cooperating with the feeding device to strip the willows.

The chief object of this invention is to produce a willow-stripping machine which will have greater capacity and shall be more efficient and reliable in its operation, and to provide cooperating feeding and stripping devices which shall be capable of automatic adjustment to compensate for the variation in thickness of the willows to be stripped.

A further object of the invention is to produce a machine which shall be simple and compact in construction whereby all of its moving parts may be completely housed if required, so as to protect the person in charge from injury by his or her clothes being caught.

Other objects of the invention will be apparent from the novel arrangement and combination of the component parts of the machine hereafter fully described and claimed.

In the accompanying drawings Figure 1 is a front elevation of the willow-stripping machine constructed in accordance with our invention; Fig. 2 is a plan view of the same; Fig. 3 is an end view of the machine minus the driving pulley and loose pulley; Figs. 4- and 5 are vertical sectional. views taken on the dotted lines ac0c and g respectively in Fig. 1; and Fig. 6 is a longitudinal section on the dotted line za in Fig. 2.

Like numerals of reference indicate like parts in the several views of the drawings.

-1 denotes the frame of the machine which may be of any suitable style or construction.

2- denotes the. main shaft which is journaled in suitable boxes 33 mounted on the base of the frame, to which shaft areprovided the usual driving pulley 4 and loose pulley 5, and 6- is the driving belt which may be shifted from one pulley to the other by any of the well known devices employed for this purpose, (not necessary to show). The stripping means comprises essentially a pair of horizontal belts -77 arranged in the same vertical plane with the lower portion of the upper belt traveling in contact with upper portion of the other belt which belts receive the willows transversely between them. Said stripping-belts 77 run on grooved wheels 88-8 8 which are keyed or otherwise secured to shafts 9-99"9*' journaled in suitable boxes 10--lO1O l0 fastened to the frame 1, motion being transmitted from one of the lower shafts 9 to the adjacent upper shaft --9* by gears 1112-- secured to the respective shafts. This lower shaft 9 is connected to a counter-shaft -13 by means of sprocket-wheels 1415- secured to the respective shafts and a chain 16, so as to drive the shaft 9 at a 1 t0 2 ratio. Said counter-shaft 13- is journaled in suitable boxes 17-17- secured to the base of the frame and is driven by means of a bevel-gear -1 secured there to and meshing with a bevel-pinion -l9- secured to the main shaft -2. We prefer to gear the shaft 13 to the shaft -2 at a l to 1 ratio, and thus drive the stripping belts 77 at comparatively low speed.

To allow the butt-end of a willow to be readily inserted transversely between the stripping-belts 7 7 we bevel the outer or contacting faces of said belts approximately from the center of their widths toward the front or feed-side and preferably make the lower bolt wider than upper belt. By thus beveling the said belts, two converging surfaces are obviously produced on the respective belts as indicated at -2021- and more clearly illustrated in Figs. 4 and 5 of the drawings. To normally maintain the stripping portions of the belts in intimate contact, we provide the lower belt -7 with a bed-plate -22 fastened by means of bolts 23--23 to brackets --2424 attached by bolts -2525t0 the standards 26 which support the willow feeding devices which devices will be shortly explained. Longitudinally over the stripping-portion of the upper belt 7 is provided a plate 27 which presses the said belt on to the lower belt. a This presser-plate --27 1s sustained yielding on the belt -7" by means of spiral-springs -2828- interposed between said plate and a parallel bar 29- arranged thereabove, which latter is secured to or formed integral with brackets -30- fastened to the aforesaid standards 26 by means of bolts -313 1-. These springs are preferably disposed in tubular posts 32-32 fastened to the top of the plate -27 and each bears with its opposite ends against the plate and a collar -33 secured to the lower end of a vertical adjustingscrew "34- working in the bar 29*. By means of said screws the tension of the springs can be regulated so as to cause the plate 27- to press the belt -7 with greater or less force upon the lowerbelt 7 as the apparent average thickness of the willows to be stripped may require, to obtain the best results. The plate 27 and bar 29- are connected by spiral-springs 3535 which serve to draw the plate away from the belt 7* when the tension of the aforesaid springs on the plate is decreased. To sustain the stripping portions of the belt laterally we provide the plates 22 and -27 with guides consisting of flanges 36-36 formed at the longitudinal edges of said plates as clearly illustrated in Figs. t and 5 of the drawings.

To insure the entrance of the butt-end of the willow between the stripping-belts and to protect the beveled surfaces of the belts from injury by contact with sharp edges in protuberances on the willow we provide two guards -3737 consisting preferably of thin steel plates arranged correspondingly with said surfaces to partly cover the same. These guard-plates are secured by means of screws 38-38- to the flanges 36-86 on the bed-plate and presserplate and the forward edges of said guardplates are deflected from each other.

The willow-feeding means consists of two pairs of parallel rubber-faced rollers 3939 of uniform size disposed at opposite sides of the belts -7-7 the rollers of each pair being keyed or otherwise secured to shafts -1040 arranged in the same vertical plane and at right angles to the shafts of the pulleys, between which pairs of rollers the butt-ends of the willows are introduced. The shaft of each of the lower feedrollers is rotated by means of a chain l1 running on sprocket-wheels 42-43 secured to said shaft and main shaft -2 respectively, the relative sizes of said sprocket-wheels being such as to drive the rollers at a 2 to 1 ratio. Motion is transmitted from each lower-feed roller to the adjacent upper feed-roller by means of gears -4445 fastened to the respective rollershafts as more clearly shown in Fig. 3 of the drawings. The shafts of the lower feedrollers are journaled in suitable boxes -46t6- rigidly supported in vertical slots at7-47 formed in the standards -26-26- hereinbefore referred to, said standards being fastened to suitable parts of the frame 1 by means of bolts l8- l8. The shafts of the upper feedrollers are journaled in similar boxes l94:9- disposed longitudinally movable in the slots d7-47 of the standards. To allow the said upper rollers to yield to compensate for the variation in the sizes of the willows being fed, we supportthe journalboxes 49-l9 on the upper ends of spiral-springs 505() which rest with their opposite ends on posts -515l secured upon the lower journal-boxes --t6t6- by bolts 5252. preferably extend through the upper ends of the standards to allow the journal-boxes to be readily applied to and removed from the standards. At the upper ends of the standards are disposed horizontal bars 5853 secured by means of bolts and extending across the slots. To said bars are applied vertical screws -5%54- bearing upon circular-shaped plates 5555-, be-

tween which plates and aforesaid journalboxes 4949- are interposed spiralsprings 5656. By the described arrangement of screws and springs the upper feed-rollers are allowed to. yield for the purpose stated.

By providing the front feed-rollers with faces of rubber having the proper degree of elasticity, the bark of the willows is split or cracked throughout the length thereof, and by driving the rollers at a very high speed in relation to that of the traveling belts 77 the bark will be completely stripped from the willow without danger of injury to willow.
