DEVICE FOR TAPPING MAINS.
SPECIFICATION forming part of Letters Patent No. 378,116, dated February 21, 1888.
Application filed October 1, 1887. Serial No. 251,264. (No model.)
To all whom 2325 may concern.-
Be it known that I, CHARLES H. SIMMONS, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Pipe-Tapping Devices, of which the following is a full, clear, and exact description.
This invention relates to an improvement in pipe-tapping devices wherein a support for a drill-press is carried bya saddle adapted to sit upon the pipe and provided with a binding chain for clamping it thereto.
The object of the improvement is to provide for a more convenient and secure adjustment of the saddle to the pipe by means of the binding-chain, and to obtain greater strength and simplicity with economy in cost.
To this end theinvention consists of certain novel details and features of construction and combinations of parts hereinafter fully described, and distinctly pointed out in the claims.
Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figurel is a side elevation ofapipetapping device embodying my improvement in use with a ratchet-drill. Fig. 2 is an end elevation of the same. Fig. 3 is a detail plan view of a part hereinafter described.
A. saddle, E, having its top and bottom V- shapcd in cross-section to adapt it to sitfirmly upon pipes of different sizes, is formed on its top with a rigid standard, A, from the upper end of which. an arm, B, projects. A drillpress, O,preferably of the common form shown, is mounted on the arm 13 to hold a ratchet-- drill, D, to its work on the pipe. The saddle E is also formed integrally at one side with a pair of eye-lugs, F, to which a chain, I, is connected by a pin, H, passed through the eye-lugs F, and the eyes of a elevis, G, on the end of the chain placed between the eye-lugs. The pin H is also passed through a pivot-hole in the end of a lever, J, interposed between the eyes of the elevis G, and arranged trans The lever J is V-shaped to conform to the top of the saddle, and its free end, which projects slightly past the opposite side edge of the saddle, is formed with a forked hook, K, so as to engage with any of the links of the chain I,when the latter is passed around the pipe to bind the saddle thereto.
A hand-screw, L, is mounted to work in a threaded hole in the inclined end portion of the lever J,against and perpendicularly to the correspondingly-inchned part ofthe saddle top as a bearing, so that by properly adjusting the screw the binding -chain can be conveniently tightened to clamp the pipe securely to the saddle, or as readily loosened to allow its disengagement from the hooked end of the lever and the release of the pipe.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, in a pipe-tapping device, of a saddle carrying a drill-press support, a pipe-binding chain, a pivotal chaintightening lever, and an adjusting-screw for the lever, substantially as described.
2. The combination, in a pipe-tapping device, of a saddle carrying a drill-press support, a binding-chain having an end elevis, a chain-tighteninglever, and a pivot-pin connecting both the elevis on the chain and the lever to the eye-lugs on the saddle, substantially as described.
3. A chain-tightening lever formed with a pivot-hole at one end and a forked chain-hook at the other end,as and for the purpose specified.
4. The combination of a pipe'saddle having a V-shaped top and bottom, a binding-chain, a V-shaped chain-tightening lever pivoted transversely on the saddle-top, and an adj ustingscrew working in the inclined part of the lever against and perpendicularly to the correspondingly-inclined part of the saddle-top, substantially as described.
