. :10F SOMERVILLE,:NEW YORK; :sgg f IMPROVEMENT IN BEER-PUMPS.

Specication forming part of Letters Patent N o. 184,475, dated November 21, 1876; application led May 4, 1876.

To all whom it may concern Ae it known that we, RICHARD MUDD, of Elizabethport, in thecounty of Union and State of New Jersey, and EDWARD MUDD, of Somerville, in the county of Richmond and State of New York, have invented au Improvement in Beer-Pumps; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which forms part of this specification.

Our invention is applicable to beer-pumps, either arranged upon a counter or upon a cabinet behinda counter; and it is designed to obviate the objectionable slots in the upper curved part of the cabinet or case which incloses the working parts of beer-pumps as ordinarily constructed, which slots admit dust and dirt to the interior of the cabinet or case, and render the apparatus more uncomely and uncleanly than a cabinet without visible openings in the interior. A

The invention consists in a peculiar construction ot' the pump-lever which operates the pump-rod and piston of a beer-pump, and of the opening through which such lever or handle protrudes through the cabinet or case, whereby the hole is closed both while the pump is in use and out of use.

Figure l in the accompanying drawing is a vertical section through the cabinet or case of a beer-pump, showing the lever or handle thereof and its connections and attachments. Fig. 2 is a section through the lever on the line a: a', and a top view of a part of the cabinet. Fig. 3 is a detail view, illustrating the manner in which the invention is applied where two or more pumps are arranged in a single cabinet or in a single case on a counter.

L is the pump-lever, provided with the ornamental handle h, and pivoted to the pumprod 1' at p, and to the top T of the case or cabinet C, or to lugs projecting from said top or attached thereto by a pivot, h. That part of the lever L which lies between the pivot p and the handle h is curved, the curvature being that of an arc of a circle whose center is the center of the pivot lo.

That part of the said lever lying between the pivots p and p may be either straight or curved; but it is so constructed that a line joining the centers of the pivots 10 p is a radius of a circle drawn from the center of the pivot p.

The hole o in the top T of the cabinet, through which the lever L passes, may have its front and back correspondingly curved in arcs or" a circle whose` center is the center of the pivot p', and the hole through the plate P may have its front and back sides similarly curved; but in any case the curved lever L is made to fit either the entire length of the said curved hole o, or the external orifice thereof as closely as possible, and yet permit an easy sliding through said hole of that part of said lever lying between the pivot p and the shoulder or flange S, formed on the lower end of the handle h.

When the handle h is in the vertical position shown in Figs. 1 and 3, the at under side of the shoulder or flange S tits closely upon the upper side of the plate P, which plate is attached to the upper side of the top T of the cabinet or case C.

When the handle h is drawn forward toand the shoulder or ange S slides upward and outward through the hole o in the top of the cabinet or case, all thewhile filling and stopping said hole, and preventingthe entrance of dust or dirt from the exterior of said case or cabinet, both while moving, as described, and when the motion is reversed.

When a number of pumps are required in one cabinet, or in a case on a counter, we prefer to use a stationary shaft, R, Fig.3, as a common pivot to the levers of all the pumps, said levers playing freely on said shaft, and' being kept in position laterally by collars o, secured to the said shaft by set-screws or otherwise.

We claiml. The combination of the curved lever L,

constructed substantially as described, and' hole o formed therein, substantially as dehaving its fulcrum p attached to the cabinet scribed.

or case C of a beer-pump, with the pump- RICHARD MUDD rod 1' and the hole o substantially as set l forth7 A H f Wm EDWARD MUDD.

2. The shoulder or ange S, provided on Witnesses:

the curved lever L, in combination with the MICHAEL RYAN, i

plete P on the cabinet or case, having the FRED. HAYNES.
