MACHINE FOR TAPPING MAINS.
A TTOHNEYS.
Unire STATES JOHN HEARNE, OF NEW YORK,` 4AND ELMER F.. CISCO, OF BROOKLYN, NEW YORK.
MACHINE FOR TAPPIN'G MAINS.
SPECIFICATION forming part of Letters Patent No. 534,881, dated February 26, 1895. Application led October 24,1894. Serial No. 526,840. (No model.)
'7.70 all whom t may concern.:
Be it known that we, JOHN HEARNE, ot' the city and county of New York, and ELMER E. CISCO, of Brooklyn, in the county of Kings, State of New York, have invented a new and Improved Machine for Tapping Mains, of which the following is a full, clear, and exact description.`
Our invention relates to a gas-tapping machine, and it has for its object to provide a machine adapted to be fastened upon a pipe, and so constructed that a hole maybe drilled, reamed and tapped in the pipe without the escape ot' gas from the machine during the operation, with no loss of gas from the pipe itself, and also without danger of asphyxiation.
A further object of the invention is to provide a gas-tapping machine which will comprise but few parts, and be very light and durable and capable of ready application to a pipe without the use or aid of wrenches, and by means of which drilling can be done at any angle.
The invention consists in the lnovel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.
Figure 1 is a central vertical section through the machine, and likewise a longitudinal section through a pipe to be tapped, upon which the machine is secured. Fig. 2 is a partial side elevation of the machine, the pipe being in transverse section, and Fig. 3 is a plan View of the ring carrying the attaching device.
In carrying out the invention the machine consists of a cylinder A, which virtually constitutes the body of the machine, the said cylinder being open at the bottom, and is provided with a stuffing box 10 at the top. The cylinder is provided further with an exterior thread 11, and with an interior thread 12 at its bottom portion. A hand wheel 13, or its equivalent, is secured upon the exterior of the cylinder, and the hub of the said wheel is provided with an exterior groove or channel 13a, in-which aring 14 is loosely fitted,
whereby the ring may turn upon the wheel. This ringis shown in detail in Fig. 3,in which it will be observed it is made in two sections a and a', each section at its ends being provided with a lug 15. Bolts 16 are passed through opposing lugs of the sections when they are in place upon the hand wheel, and a hook 17 is pendent from each of thesaid bolts. The said hook, however, may be substituted by an eye or au equivalent, the hooks being adapted to receive links of a chain 18, after said chain has been passed around the pipe B to be tapped.
A standard 19 is erected preferably upon the top portion of the cylinder, and said standard is curved at its top inwardly over the box 10, and at its upper extremity the standard is provided with a feed screw 20, turned usually by means of a hand wheel 21,01' like de vice. A drill or combination tool C, is passed into the cylinder and through the stufngbox 10, and the lower portion of the said tool is formed with a drill point 22, a reaming section 23 and a tapping section 24. The upper portion of the shank of the tool is squared or rendered polygonal, as shown at 25 in the ....drawings, to receive, for example, a ratchet wrench 26, and the feed screw is adapted to have bearing upon the upper portion of thiswrench when in place, as shown in Fig. 1.
A collar 27 is provided with a iange 28, which is fitted to the outer contour of the pipe, and the said flange, or the collar proper, is provided with a suitable packing 2,9. The exterior of the collar iange is threaded in or der that the cylinder of the machine may be screwed thereto. Thus, in operation, the collar is made to fit upon the exterior of the pipe around the surface that is to be tapped. The chain 18 is attached to one of the hooks 17, and is then passed around the pipe and secured to the other hook, and the hand wheel 13 is thereupon manipulated to tighten the chain in a manner to hold the machine firmly upon the pipe, the packing 29 in the collar 27 preventing the escape of gas from the machine. The ratchet is then manipulated together with the feed screw 20, and after the drill point has made a proper hole in the pipe the roaming section 23 will ream the said hole, while the tapping section 24. closely following will tap the hole. Meanwhile any gas IOO thatmay have escaped will be contained Within the chamber A, from which it can not escape, and consequently no odor of gas occurs where the tapping is carried on.
The machine, after the tapping is completed, may be quickly removed and a plug placed in position, to close the tapped hole.
This machine is light, simple and durable, it is portable and is capable of ready application to a pipe, or disconnection therefrom.
Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a tapping machine, the combination of the body having a screw threaded portion, a hand-wheel threaded to screw on the screwthreaded portion of the body, and a ring loosely carried on said hand-wheel and provided With means for attaching achain thereto, substantially as set forth.
2. In a tapping machine, the combination of the body having a screw-threaded portion, a hand-wheel threaded to screw on the screwthreaded portion of the body and provided with a peripheral groove, and a ring loosely mounted in said peripheral groove and provided with means for attaching a chain thereto, substantially as set forth.
3. In a tapping machine, the combination of the body having a screw-threaded portion, a hand-wheel threaded to screw on the screwthreaded portion of the body, and provided with a peripheral groove, and a ring composed of two sections connected together at, and having hooks arranged between their adjacent ends, said ring being arranged inpsaid peripheralgroove in the hand-Wheel, substantially asset forth.
4E. In a tapping machine, the combination of a hollow exteriorly screw-threaded body adapted for air-tight connection with the pipe to be tapped, a feed mechanism, a tool operated from the feed mechanism and located in the hollow. body, and a hand-Wheel having a threaded portion adapted to screw on the eX- terior screw thread of the body and provided with means for attaching a chain thereto, substantially as set forth.
5. In a gas-tapping machine, the combination, with a collar provided with aseat adapted for gas-tight connection with a pipe,a cylinder connected with the co1lar,a hand wheel adjustable upon the cylinder, a ring loosely mounted upon the wheel, and a clamping chain adapted to be carried by the said ring, of a feed device, a tool entered into the said cylinder in a gas-tight manner, terminating at its lower end in a drill point, a reaming section land a tap section, and means, substantially as shown and described, for rotat- 6o ing said tool, as and for the purpose specified.
