LEAK STOPPING GLAND.

BEST AVAlLABLE COP v UNITED STATES PATENT OFFICE.
LEAK-STOPPING GLAN D.
To all whom. it may concern.-
Be it known that I, JACOB PATRICK HANSON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Leak Stopping Glands, of. which the following is a specifica tion.
My invention relates to leak stopping glands, and belongs directly to that type or class of devices comprising a divided frame adapted to encircle a steam-pipe near a joint and to be clamped upon the pipe and devices arranged to compress suitable packing against the joint or portion thereof where the leak is situated.
- The object of my invention is the production of a contrivance of the character mentioned having particular construction and arrangeme-nt of parts believed to render the in ,vention more eflective in stopping leaks in f-pipe-joints whatever pressure may be on the pipes and which cheapens the cost of the invention by providing substitute portions that may be employed in place of more expensive parts. For example, where leaks occur at intervals entirely around the pipe at the joint it is necessary to use the pipe-clamping ringframe of my invention entire; but where there is but a single leak at one point the user need only purchase and use a portionordinarily one-fourth partof the entire pipe-clamping ring-frame, substituting for the remaining parts a cheap metal member, as fully described .hereinbelow.
I accomplish the objects stated by fashioning and associating parts as illustrated in th accompanying drawings, of which Figure 1 is a side view of a pipe-joint having my invention shown in section applied thereto. Fig. 2 is a front view of the divided presser-ring having its parts pivotally connected. Fig. 3 is an edge view of the members composing the spring and the securingkeys. Fig. 4 is a front or interior view of the pipe-clamping ring-frame, the pipe within it being shown in section. Fig. 5 is a front view of the pipe-clamping ring-frame, showing the position of a modified spring-ring about the pipe. The pipe is in section, and in this view appears a one-quarter substitute fractional clamp member. I Fig. 6 shows the application of one-quarter of the pipe-clamping ring-frame with a fractional spring-ring and a three-quarter substitute clamp member.
Specification of Letters Patent.
Application filed August 17, 1905. Serial No. 274,531.
Patented Dec. 19, 1905.
Like letters are employed to refer-to like elements throughout.
Considering Figs. 1, 2, 3, and 4, the parts will be seen which constitute the entire invention as shown assembled in Fig. 1. The let tcrs A and B designate two pieces of steampipe coupled by the elbow 0. Assuming it is desired to stop one or more leaks in the joint between the pipeA and the elbow C, I first place next to the joint a ring of packing D of any chosen substance in the form of a ring having a rectangular cross-section. be unnecessary to show thatthe ring of packing must be divided at some point to enable it to be placed around the pipe. The letters E and F mark the upper and lower twin members of spring metal, which engage each other and form the springring,'as best shown in Fig. 3, and are placed around the packing D exteriorly. The letter G marks a flat ring comprising two halves pivotally secured to each other by the pin H and having overlapping ends J and K, which when closed one upon the other after the ring has been placed around the pipe make practically a continuous fiat annular band resting against the ver-" iical outer face of the packing D, as shown in The part termed in this description the pipe-clamping ring-frame is designated by letter L. It may be divided into separable parts, as illustrated. Two sets of screws pass through the ring L, and the ring may have relatively thickened portions to give the threads of the screws sufiicient hold. The radially-disposed screws are marked M, and these exert pressure at intervals around the spring-ring members E and F. The screws arranged parallel with the axis of the ring are referred to by the letter N, and these screws act upon the divided ring G. It is believed to be now shown and explained that if ringL be clamped about the pipe A the spring-ring It is thought to and the divided ring G constitute a stulfingbox within which the packing Dmay be compressed against the pipe-joint by the action of screws M and N.
In assembling my inventionI have arranged that the halves of ring Land the halvesE and F' of the spring-ring, which are placed together, as stated, upon the outer curved surface of the packing, may be handled as single piecesthat is to say, the upper half of ring L and the upper member E-of the sprin ring may be joined together and hand" plvvidened to the diameter of the pipe.

one piece, and the same is true of the lower half of ring Land the member F of the springring. I effect such arrangement by providing the members of the spring-ring with turnkeys 0, having conical retaining heads 1?, flush with the inner surfaces of the springring members. The keys are shown in Fig. 3 turned edgewise and broadside to the ob- When turned broadside, the keys pass through slots R in ring L and are then turned to retain the spring member and ring L together, as will be'understood from Fig. 5.
The pipe-clamping ring-frame L is relatively an expensive piece to make, and when leaks are located at one or more points throughout-for example, three-quarters of the circumferential joint-the user may purchase three-quarters only of ring L, substituting for the remaining one-quarter a cheaper complementary clamp member 8. Under these conditions the spring ring element T need be but a plain band T, as shown in Fig. 5, or if only one-quarter of ring L is purchased and used the spring-ring no longer-is employed 'and the quarter-lengthband U is all that is 'needed with a corresponding extent of packing. Under those circumstances the substitute cheap clampingmember V must obvi-' ously possess suflicient'flexibility to permit the opening between its extremities to be It is my purpose to construct the ring L of brass or bronze and the substitute membersof iron and steel, thus making them much more cheaply. v Having now described my invention and explained the mode of its operation, what I claim is 1. In a leak-stopping gland, the combination with adivided pipe-clamping ring-frame, of the spring-ring members E and F, a diframe whereby said spring-ring members and flat ring are pressed upon, substantially as described.
2. In a leak-stopping gland, the combination with a divided pipe-clamping ring-frame, of spring-ring-members, and means for removably connecting the ring=frame divisions and spring-ringmembers, substantially as described. p
3. In a leak-stopping gland, the combinavided flat ring, and screws borne by said ringtion With a divided pipe-clam ping ring-frame,
of spring-ring members, the said ring-frame being provided with slots R, and the springring members having the turn-keys O adapted to be passed through said slots whereby the divisions of the ring-frame and said springring members are separably connected, substantially as described.
4:. In a leak-stopping gland, the combination with pipe-clamping-frame divisions, of a substitute complementary clamping member constructed andarranged substantially as described.
5. In a leak-stopping gland, the combination with pipe-clamping ring-frame divisions, of a divided spring-ring and adivided fiat ring coextensive with the ring-frame divisions, and screws borne by said divisions arranged to press upon the said spring-ring and flat ring, substantially as described.
In testimony whereof I affix my signature in presence of-two witnesses.
