IMPROVEMENT IN APPARATUS FOR AITACHING PUMPS T0 BUNGS OF BARRELS.

Specification forming part of LettersPatent N0. 40.082, dated September 22, 1863.

To all whom t may concern.-

Be it known that l, FRANCIS A. PRATT, of the city and county of Hartford, in the State of Connecticut, have invented a certain new and useful Fastening for BarrelPumps; and I do hereby declare that the following` is a full, clear, and exact description thereof, ref erence being had to the accompanying drawings, making part of this specification, and to the letters ot' reference marked thereon, in Which- Figure l represents a cross-section of a bar rel with my invention applied thereto as a means of fastening for a. rotary pump. Fig.

2 is a side elevation of part of the suctionpipe of a pump and the apparatus for fastening the pipe to a barrel. Fig. 3 is a plan view of the same; and Figs. 4, 5,6, 7, and 8 illustrate an invention for which I am about to apply for separate Letters Patent.

Similar letters of reference denote the same part in the several gures.

My invention relates to an'apparatus by which a portable pump may be secured to a barrel.

Previous to my invention much inconvenience and waste of time and labor have been experienced in the use of barrelpumps on account of the insuiicient means which have been employed to secure the pump to the barrel, and in consequence of which the pump has been so loosely held that it is liable to change its position with every effort to work it. A

lt is the object of my invention to furnish a device by which a pump may be rigidly fastened to a barrel, in such a manner as to permit the rapid and advantageous working' of the pump, and which may be adjustable to various sizes of barrels.

To these ends my said invention consists in the employment, in combination with the rigid suction-pipe of a portable pump, of a saddle or crab, a hooked bolt for clamping the crab to a barrel, and a setscrew for clamping the suction-pipe to the crab, or their respective equivalents, constructed, arranged,

and operating substantially in the manner hereinafter clearly set forth.

To enable others skilled in the arts to make and use my invention, I will proceed to a description thereof.

In Figs. l, 2, and 3, to which the following description refers, a is the rigid suction-pipe of a rotary pump, B. c is a four-footed crab, of which d d d d are the legs or feet. The hub of this crab loosely encircles the suctionpipe a of the pump. bis a bolt, the lower end of which is formed into a hook,f. Its upper part is threaded, and passes through a hole made in the hub of the crab o, parallel with its axis. The nut g of this bolt b bears on the top of the hub of the crab. h is abinding-screw, which is screwed into one side of the hub of the crab c and reaches through the side, so that its point may be made to press against the suction-pipe a, and thus firmly clamp the suction-pipe to the crab c.

To make use of the apparatus which I have described, the hooked end f of the bolt I is thrust into the bung-hole of a barrel, and is hooked under the edge of the hole. (See Fig.

l.) The crab c, supported on its four feet, which straddle the bung-hole, is iirmly clamped down onto the surface of the barrel E by screwing down the nut g of the bolt b. The suction-pipe a of the pump is now thrust through the hub of the crab down as far into the barrel as it may be desired, and the binding-screw h is then turned so as to clamp the pipe securely to the crab, by which means the pipe a, and consequently the pump B, are immovably secured to the barrel, and cannot be drawn out nor in any way displaced bythe act of pumping.

The threaded part of the bolt b should be of sufficient length to adapt the apparatus for use on barrels having different thickness of staves.

The feet d of the crab c may be made very much shorter than represented, as they need only be long enough to support the crab steadily upon the curved surface of the barrel, or a curved square plate-like a saddle-a bined, arranged, and operating to secure a barrel-pump to a barrel substantially in the `manner hereinbei'ore described.

In testimony whereof I have hereunto set my hand this 24th day of August, 1863.
