EUGENE lWI. DUNPHE AND CHARLES BLOOKHOUS, OF EAST BRIDGEVVATER,

MASSACHUSETTS.

LSEATHER-SPL'ITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,697, dated June 25, 1889.

Application filed March 18, 1889.

Serial no. 303,942. on) model.)

To all whom it may concern:

Be'it known that we, EUGENE M. DUNPHE and CHARLES BLooKHoUs, of East Bridgewater, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Feed-Roll Attachments for Leather Splitting Machines, of which the following, taken in connection with the accompanyingdrawings, is a specification. To The object of our invention is to connect with a leather-splitting machine a brush-belt adapted to automatically free the lowerfeedv roll from all accumulations of debris, dirt,

&c. This object we attain by the mechanism :5 shown in Y the accompanying drawings, in

which- Figure l is a cross vertical section showing the feed-rolls and a part of the frame-work of a leather-splitting machine with brush device attached. Fig. 2 is a longitudinal section of the same taken on line as a; of Fig. 1. Fig. 3 is a view in plan, showing parts of the machine. 4is a view in perspective, show ing the parts in which our invention is em- 2 5 bodied.

In Fig. 1, A represents the main frame of the machine; B and B, the upper and lower feed-rollers, the lower feed-roll being fluted. The flutings are much exaggerated for the purpose of illustrating the use of our attachment.

0 represents the knife.

We will not explain the other well-known details of this device, as they are common to machines of this class.

Our cleansing attachment works automatically and consists of a brush made up as a belt, (see D and is adapted to be driven by one of the pulleys that supports it. The bru sh-belt D is driven by the pulley D, which is hung on a pin D, fitted to a bracket K,

which extends from the box. K.

In Fig. 2 we have shown both of the pulleys D and D that support the belt D The pulley D is connected to a sliding bracket-piece D 5 which can be adjusted byathumb-nut D", by the aid of which the brush-belt D? may be drawn taut.

D is a screw working in a slot formed in the end of the sliding bracket-piece D and serves as a guide for the movement of the bracket -piece D and also as a clampingscrew to hold it firmly in place after being .adjusted. i

The brush-beltD is driven by the following mechanism: B Figs. 1 and 3, is a gear-wheel attached to the shaft of the feed-roll B. (See Fig. 2.) This gear-wheel engages with a gearwheel E on the shaft E, and through itand its beveled gear E driving the beveled gear E, which in turn gives motion to the attached 'pulley D on the pin D. Thepulley D, as has been stated, gives motion to the brush-belt D? As the bracket K is rigidly attached to the boX K, in which the shaft B of the feed-roll B runs, it will be understood that in raising or lowering the box K for adjusting the feedroll 13 the brush-belt D will also be raised and lowered, so that the brush part will always be in working contact with the fluted feed-roll B. The brush-belt D running parallel with and in con tact with the feed-roll B, frees it of all accumulations of debris of all kinds, and thus always keeps it in good order for doing its work.

To aid the brush-belt D in its work, a 1ongitudinal supporting-piece H, Figs. 1,2, 3, and 4, is used. This supporting-piece is held by bracket-pieces ll, attached to the frame of the machine by adjustingscrews H 1. In a leather-splitting machine, the combination of the feed-roll B" and the brushbelt D adapted to operate substantially as described, and for the purpose set forth.

2. In a leather-splitting machine, the combination of the feedroll B and brush-belt D with the adjustable box K and bracket K, substantially as and for the purpose set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 14th day of March, A. D. 1889.

EUGENE M. DUNPHE. CHARLES BLOOKHOUS.
