J. H. ASH. PLUMBBRS CLAMP.

STATES PATENT OF ICE.

JOSEPH HOWVELL ASH, OF BROOKLYN, NEIV YORK.

PLUMBERS CLAMP.

SPECIFICATION forming part'of Letters Patent No. 474,713, dated May 10, 1892.

Application filed March 15, 1892.

T0 at whom it may concern:

Be it known that I, JOSEPH HOWELL ASH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Plumbers Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plumbers clamps for holding and supporting a pipe, cook, or fit. ting during the process of wiping a joint.

The object of the invention is to providea clamp that will be efficient, convenient of operation, light, simple, and capable of being packed in a small space, so as to be readily carried in the plumbers bag without materially increasing the bulk or adding to the weight of the tools usually carried when jobbin.

The invention consists of a clamp composed of two members which are adapted to be pivotally connectedtogether and grip the pipe between them, the free ends of the said members being constructed to be fastened in a proper relation and form a support for the clamp.

The improvement further consists of the novel features and the peculiar construction and combination of the parts, which will be hereinafter more fully described and claimed,

and which are shown in the annexed drawings, in which Figure 1 is a perspective view showing the application of the invention. Fig. 2 is a perspective view of a modification in which the members of the clamp are detachably connected together and showing the foot of the members apertured to receive a spike or pin. Fig. 3 is a further modification showing the pivotal connection of the members of the clamp between the gripping-jaws and the feet.

Usually there will be three clamps to a set two to support the main pipe and one to supportthe branch pipe. Obviously the number of clamps to a set may be varied. The invention residing in the construction of the clamp, the following description will be restricted to a single clamp.

The clamp comprises, essentially, two mem- Serial No. 425,021. (No model.)

bers A and B, which are similarly constructed, being rights and lefts, and which are adapted to be pivotally connected together.

In Figs. 1 and 2 the members are represented as being pivotally connected together at one ground.

The pivotal connection between the memb rs A and B may be permanent,-as shown in Fig. 1, or detachable, as shown in Figs. 2 and ,3. The latter form is preferred because it admits of the clamp being packed in a small space and because the members can be separated and placed the one on the other.

In Fig.3 the pivotal connection of the memhers is placed between the jaws aand b and the feet. The operation of this form of clamp is substantially the same as that shown in Figs. 1 and 2, although the form is somewhat changed. Of course to clamp the jaws on the pipe the footed ends of the members are separated, whereas in the form of clamp shown in Figs. 1 and 2 they are brought together.

To use the invention, the pipe E is placed between the jaws of the clamp, and if the form be that shown in Figs. 1 and 2 the footed ends of the members are brought together to grip the pipe firmly. If the feet are provided with prongs, the latter are driven into a plank or board, thereby securing the clamp in a fixed position. In the event of a board not being at hand the clamp can be set up on the ground and a long nail or wooden pin can be driven through the apert ire in the feet of the members. Should the form of clamp be that shown in Fig. 3, the footed ends of the members are'separated to clamp the jaws on the pipe, the clamp being secured in precisely the same manner as above specified.

The clamp is composed of strips of metal wide and thick enough to possess the strength required, and yet not be cumbersome or weighty. Strips of plate steel have been found best for the purpose.

It will be observed that the footed ends of the members are separated or spread apart, thereby obtaining a firm footing for the clamp. This is an essential feature in the organization of the clamp.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

1. Aplumbers clamp composed of the members which are constructed to be pivotally connected together, and having jaws to receive the pipe or fitting to be held, and having the footed ends spread and constructed to be fastened and form a support for the clamp, substantially as specified.

2. A plu mbers clamp composed of the members which are constructed to be detachably connected together by a pivotal joint, and having jaws to receive the pipe or fitting to be held, and having the footed ends spread and constructed to be fastened and form a support for the clamp, substantially as specified.

3. The hereinbefore-specified plumbers .clamp, composed of two members which are adapted to be pivotally connected together at one end, and having the opposite ends of the said members footed and provided with prongs, which are adapted to be driven into a plank to secure the said ends and fasten the clamp in a fixed position, and having jaws formed in the said members near the pivotal connection, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses JOSEPH HOWELL ASH. Witnesses:
