CLAMP.

SPECIFICATION forming part of Letters Patent No. 702,416, dated June 17, 1902.

Application filed November 17, 1900. Serial No. 36,852. (No model.)

To ctZZ whom it nuty conocrm.

Be it known that I, JOSEPH FELLO WS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvementsin Clamps, of which the following is a specification.

The object of my invention is to provide a view showing the clamp secured to the head of the barrel and to the pump. Fig. 4 is a plan view of the clamp. Fig. 5is a detached perspective view, and Figs. 6 and 7 are views of modifications of details.

Referring to Fig. 1, A is a barrel, B is a molasses-pump, which is inserted through a hole in the head a of the barrel. The bottom of the pump has, preferably, one or more spurs which enter the lower head of the barrel and hold the end of the pump in position.

D is the clamp for securing the pump to the upper head of the barrel. The clamp passes between the edges of the opening in the head and the pump-tube. The clamp is made in two sections, D D Each section has a flange d, a ribbed portion 02', and an extension d which enters the barrel. This we tension has a fianged which bears against the pump-tube. In the section D is a setscrew E. This set-screw bears against the pump-tube and forces the sections D D apart,

as shown in Fig. 3. On the flange d of the section D in the present instance are lips c c, which overlap the flange d of the section D and hold the sections in position. The ribs of the portion d of each section are preferably made as shown in the drawings, the lower edge of each rib being tapered more than the upper edge, so as to prevent the pump being lifted off of the bottom of the barrel when once in place.

It will be noticed in referring to Fig. 3 that there are two points 00 at Where each section of the clamp bears against the pump-tube, and between these points the ribbed surface cl bears against the edges of the hole in the barrel head. Consequently when the setscrew E'on the section D is turned, its end presses against the pump at m, and the other bearing-point :r' acts as a fulcrum, and as the clamp is expanded its ribs d are forced into the wood of the barrel-head, thus holding the pump rigidly in the barrel.

Other means than the set-screw E may be used for spreading the clamp. For instance, a wedge E, Fig. 6, may be used, the wedge having a slot e, through whicha securingpin 6 passes, so that it will not become detached. After the clamp is in position the wedge can be driven so as to force the section D out against the edge of the opening in the barrelhead. y

In Fig. 5 I have shown the clamp made of two independent sections; but they may be secured together by a chain or by a loose pivot, as in Fig. 7. A

While I have shown ribs to engage the head of the barrel, it will be understood that any suitable projections may be used on the clamp which will engage the barrel and prevent the pump moving when once secured in position.

I claim as my invention- 1. The combination in a clamp, of two sections, each section having internal bearingpoints at top and bottom only and a single external bearing-point between the two internal bearing-points, one of the internal bearing-points on one section being adjustable, substantially as and for thepurpose specified.

2. The combination in a clamp, of. two sections adapted to be inserted in the hole in a barrel, and to encircle a pump, each of said sections having an outer bearing-surface engaging with the barrel, an extended portion engaging the pump, and means for forcing one of said sections out at the top, the lower bearing acting as a fulcrum whereby the clamp is securely fastened to the barrel and to the pump, substantially as described.

3. The combination in a clamp for securing pumps to barrels, of the two sections adapted to be inserted in a hole in a barrel and encircling a pump, each of said sections having a flange, and a ribbed or roughened portion directly under the flange to engage the barrel and having an extended portion, the lower edge of said extension bearing upon the pump, and means carried by one of said sections for forcing the upper portion of the said section out, thus expanding the clamp and securing the pump to the barrel, substantially as described.

4. The combination of a clamp made in two sections,each section having a fiange,a ribbed portion under the flange arranged to engage the barrel, the upper edge of each rib being abrupt and the low edge inclined, each section having an extension with an internal rib arranged to bear against the pump,and means carried by the upper portion of one of the sections for forcing the upper end of said sec- JOSEPH FELLOWS.
