LEATHER SCOURING AND WRINGING MACHINE.

SPIOII'IOATION forming part of Beissued Letters Patent No. 9,824, dated August 2, 1881. Ori inal No. 23$,l3l, dated December 1, 1880. Application for reissue filed May 13, 1881.

To all whom it may concern:

Be it known that I, Jomv W. CUBBAGE, of Gallipolis, in the county of Gallia and State of Ohio, have invented certain new and useful Improvementsin Leather Scouring'and Wringing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention,\that will enable others skilled in. the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

Fi re 1 is a side elevation of my improved leather scourer, w-ringer, &c. Fig, 2 is a similar view taken from the opposite side of the machine. Fig. 3 is a longitudinal section of the same, and Figs. 4 to 8 are detail views thereof.

This invention relates to improvements in machiuesfor tannersuse,principally for scouring to aid thetanning of and'wringing leather, and for working hides out of the bate. It is further applicable for breaking and softening hard dry hides,as well as unhairing and slicking hides; and the nature of my invention consists of the combination and arrangement of parts, substantially as hereinafter more fully set forth and claimed.

In the accompanying drawings,-A A indicate side supports or castings, with suitable legs, A A, which are connected together by transverse pieces b, and the side pieces or supports by the end board, 0, all securely bolted in position.

a B is a rearwardly-incliued endless apron encompassing rolls (1 d, one journaled in fixed boxes at the rear end of the machine and the other journaled in sliding boxes 0, operated in slots in the forward ends of the supports Aby the adjusting or thumb screws F. This per-.

mits of the tightening up of the belt or apron as occasion may require, and also of slackening up on it to relieve it of strain when not in use, and that the roll d, working in the sliding boxes 0, may be taken out and the apron folded up under the front end of. the machine, when the latteris used for wringing purposes.

0 is the work-table upon which the leather (or hides) is worked or treated while being scoured or otherwise acted upon by the work- *ing-wheel, hereinafter described. This table has two side bars, 9, with their rear ends hung upon the removable rod 9' at the rear end of vertically adjustable in the side supports or pieces, A, to permit of adjusting the height of the table, when needed. The table also has a flexible or elastic surface with one end secured to a cross-bar fastened upon elevationsof the bars g, while its forward end is carried around, or'rather against, a. series of small cylinders or -rol'ls, j, slipped upona-rod or bar, j, secured in the forward ends of the bars'g, as clearly shown in Fig. 3. It is then connected to aseries of springs, k, the opposite ends of] which are secured to a board, I, of the table by means of adjustable bolts or nuts I.

The series of short cylinders J permits the flexible table to give or yield at any one or more points to lumps or from any other cause, while the springs keep the table properly stretched and tightly drawn, the tension being regulated by the bolt and nut.

The rear end of the lever is adapted to en-.

gage and be held at any desired height of adjustment by a rack,-m. The. rack m has its arms pivoted in the rear end of one of'the sup ports A, so as to permit it to be swung from one side of the support to the other, and is se-' cured in a fixed position by a spring-pawl, n. The rack, being adapted to swing, can he turned out of the way for removing the worktable.

, E is the working-wheel, with its shaft hung The'fulcrum of the lever D is a cross-bar, i,

boards or brushes F, which are capable of vertical adjustment by means of nutted screwbolts passing through slots in the boards, and formed with brackets F, fastened to the backs or boards of the brushes, as seen in Figs. 3

and 4. These brushes wipe or remove surplus water from the leather or hides. Other of these 15 boards 12 have connected to them parallel boards p by bolts with intermediate spaces to receive and permit of the clamping between them of stones or scout-era pf. These stones or scourers are disposed around the wheel-say about two consecutive rows-extending in the direction of the length of the wheel to a brush,

- by which arrangemen t,as the leather(orhides) is acted upon or secured by the scourers such will be followed by the action of a brush, and z 5 thus scour and simultaneously wipe off the sediment and the water after it has had the effect to clean, and with the scourers to open the pores and soften the leather or hides.

Upon the shaft of the scouring or working wheel is a baud-pulley, q, having an attached gear-wheel, g, and a clutch-sleeve, q, both beingloose upon the shaft, while projectingtransversely through and from the shaft is a pin,

q, and from the side of the gear-wheel q! pro 3 5 jections g. The clutch-sleeve g? has slots indeuting it to receive the pin 9 to cause it'tn turn with thescourer-shaft. Itis also capable of slidip g upon the shaft to enableitto he slid up to and its slots to receive the projections q upon the wheel q, in engagement with which itis held by asprin g, r, to cause the band-pulley q and wheel q to revolve with the shaft.

A hand or crank screw, r, working in a bracket, r, of one of the side pieces, A, is adapted by turning the screw with the hand to permit of releasing and applying the clutchsleev'e, as occasion may require.

Hung obliquely in boxes on one side of the machine is a shaft with ascrew or worm, a, and 50 a pinion, s, which engages with the gear;

. wheel 9. This gearing, in connection with a pinion on one of the feed-rolls, presently described, permits of the simultaneous operation of the feed-rolls and the scourer. I

G G are the feed-rolls, one having its shaft provided with a pinion, t, gearing with the worm a, as aforesaid, and journaled in boxes upon the upper edges of the side pieces, A. The upper roll is hung in boxes u, supported 60 and retained in position by the upper ends of bifurcatedor slotted uprights or slides H, suit ably supported upon the sides of the machine.

7 The journal-boxes u have a limited upward movement, and are yieldingly held down upon 65 the shaft of the roll by means of springs u u,

nutted upon rods or extensions of upright supas they are fed between the rolls down-under 7 held by a spring or otherwise, and the other 7 sides A. The leather or hide is fed to the feed- .rolls upon the endless apron K, encompassing 9 vrolls K. The shaft of one of these rolls-that or curved plate with a slot in its horizontal porthe' thickness of the leather or hides to be ports carried above the boxes, as shown iu' Figs. 1 and 2, to secure pressure upon and to allow for unevenness in the leather or hides the scourer and to and upon the work-table.

To prevent adherence of theleather or hides to the rolls G, scrapers I I are arranged so as to bear against the rolls, the lower one being one, which is hung by arms V, pivoted in uprights V, suitably secured in position, caused to rest against the upper roll by gravity.

J is a sprinkler hung between the feedu'olls and the scourer, to sprinkle water upon the leather or hides as they pass from the rolls under the scourer. .-It consists, mainly, of a serially-perforated tube with a pipe or nozzle, J to which a hose or-pipe may be connected leaiding from the supply of water or service-pipe 8 for supplying water to the sprinkler. The tube is provided with upwardly-extending arms J, hung upon uprights or rods J, attached to the contiguous to thelower feed -roll--bears in boxes w, which consist each of a hook-shaped tion, whereit is attached to the upper edge of 9 the sides A, to permit of the adjustment of the said roll to allow for difl'eren'ces in the thickness of the apron without its coming in con tact with the lowe'rfeed-roll. The boxes 10' of the other roll-shaft are capable of adjustment by means of the adjusting-screws w, as seen in Figs. 1 and 2, to-allow of stretching or tightening and loosening it, as occasion may require. Y

L is a trough, preferably with a semicircular bottom and a discharge-spout, L, Fig. 2, and secured under the forward end of the apron Kwith its side edges, one resting against the lower feed-roll and the other against the lowerside of the apronaforesaid, provided with any suitable material adapted to wipe off the roll and apronto free them of water .while wringingthe leather; but,ifdesired, thetrongh may or may not have attached to it means for acting on the lower feed-roll and apron, as aforesaid.

M is-a shaft hung on the side supports, A, with wheels M on its ends, whose blades or teeth are adapted to engage and revolve pin-' ions N, free to revolve upon short screw-shafts N, formed on the lower ends of the uprights 11.. As the piui'ons N are rotated they will effeet the vertical. adjustment of the standards to permitof the widening or narrowing of the space between the feed-rolls, to accommodate passed between them.

' A sprocket or rag wheel, a, fixed to the shaft M, with a'chain-belt, a, passing around it, and aisimilar wheel, a, suitably journaled upon a bracket, a, fastened to one of the side supports, A, and having a crank, a, permits of theoperation ofthe shaft M with its wheels, and the consequent vertical adjustment of the standards H with the. upper feed-roll. lower feed-roll is geared and imparts motion to the forward roll of the feed-apron'K by the gearing P P P, adapted to permit of the said roll having a relative adjustment to the said .feed-roll,as before stated.

When the operation of wringing is to be performed the-supply of water is .cut ofl from the sprinkler, the scourer put out of opera tion, the work-table removed, and the apron K folded up or under the machine out of the way. The scourer can be adapted to permit of the slicking and unhairing of the hides by accordingly substituting in lieu of the stones and brushes means suited to those ends. It is capable of breaking and softening hard dry hides.

Having thus fully described my invention, I claim anddesireto secure by Letters Patent 1. The table 0,with its flexible surface passed ar'ound a series of sectional cylinders, j, fitted upon a cross-bar,j', of the table-frame, sub.- stantially as and for the purpose. set forth.
