PIPE-COLLAR.

sPEcIFIcATIoN forming' para of Letters traitent No.6o8`,o6o, dated July as, 189s. `Application filed January 24, 1898, Serial No. 667,799. (No model.)

' To if/ whom t may concern:

scription.

My inventionrelates to` pipe-collars especally adapted for exposed piperisers that' pass through finished ceilings, floors, and walls.

rThe object of the invention is to construct such a device in a simple, durable, and economic manner and so that the device may be expeditiously and conveniently applied to hot# water or steam supply, steam or hot-Water return, and air-vent pipes in`pipe-risers;without marring the ceiling or wall.

A further object of the invention is to so constructthe device that it will admit of eX` pansion and contraction and obviate cutting the templets, as the portions ofthe collar can be adjusted to suit any riser whether out of4 line or square.

A further object of the invention'is to provide a pipe-collar which will admit of the filling of fireproof material around the pipes and which will prevent the dropping of any dirt and the passing ot' anynoise or any bad odors from one iioor to another.

The invention consists in the novel 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 in which similar characters of reference indi` cate corresponding parts in all the figures.

Figure l is a verticalsection on the line 1 1 in Fig. 2 through a portion of the iioor and ceiling, illustrating the application of the device. device constructed for application to a ceiling, the pipes passing through the device being shown in horizontal section.V Fig. 3 is a horizontal section taken substantially on the line 3 3 of Fig. 1, and Fig. 11 is altransversesection taken substantiall y on the line 4 lof 5o Fig. 3.

A represents a section of flooring, D a por- Fig. 2 is a bottom plan View of the` tion of the ceiling, and C the casing, vwhich eX- Be it known that I, EDWARD J. IVIALLEN, of the city of New York, borough of Mamv hattan, in the county oi' New York and State of New York, have invented a new and use-, ful Improvement in Pipe-Collars, of which the following is a full, clear, and exact de-` tends through correspondingopenings made in the floor and in the ceiling, through which casing the steamsupply pipe D is passed, the return-steam pipe D', and the air-vent D2. `The body of the device may be` given any desired shape. Preferably, however, it is of i somewhat elliptical form and is in the nature of a plate 10, made in itwo sections a and ct',

yeach section of the body being provided with a marginal flange l1 and with an inner opening 12. One section ofthe body is further provided with lugs 13 at its ends, the said lugs being formedat the inner face of the section, and the lugs are arranged to extend over the corresponding surface of the opposing sectionof the body, the two sections of the body being connected by screws 14, which pass through the outer4 face of the section Aoverlapped by the lugs 13 and into said lugs only when` the device is to' be applied to a ceiling; but when the device is to be applied.

to a floor the screws 14 pass through and beyond the lugs and are made of sufficient length to enter the floor, as shown at the upper portion'of Fig. 1.

Upon what may be termed the inner "face of the body lugs 15 are formed at the end at each side of the center, the lugs extending inwardly or in direction of the center, and at each side of each section, also upon the inner face, a lug 16 is formed, extending from the flange inwardly or in direction of the cenyter of the body.

`In connection with the body usually three clamping- plates 17, 18, and 19 are employed, the clamping- plates 17 and 18 being at the plate 19 at the center. The clamping-plates are held between the lugs 15 and 16 and the. inner face of the body.

.The clamping-plate 17 is provided with an opening 17 a, adapted to receive, for example, the steam-supply pipe D, and `spurs 17'b are formed at intervals at the margin of the said openingl to engage with the said pipe and allow of the expansion `and contraction thereof. The clamping-plate 1S is similarly provided with an opening 18, receiving, for example, the return-steam pipe D', and at the margin of this opening 1S spurs 18b are also formed to engage with the end portions of the body and the clampingi pipe; but in the central clamping-plate 19 an uninterrupted opening 19a is formed, which is adapted to receive an air-vent D2.

The clamping-plate is provided with a cut 2O or is divided from one side to the opening 17a. The clamp 18 -is similarly provided with a cut or a division 21, and the central plate 19 also has a out or a division 22 produced therein, extending; from one of its edges to the opening 19, as is clearly shown in Figs. 2 and 3. The clamping-plates are made of a spring material-as, for example, sheetbrass-and by. reason of the cuts made therein the sections of the plates adjacent to the cuts may be carried in opposite directions and the several plates readily slipped upon the pipes they are` designed to receive. After the pipes have entered the openings in the plates and the plates are released they will assume their normal position and be perfectly fiat.

The end plates 17 and 18 slide over or rest upon the central plate 19 when the device is attached to a ceiling; but when the device is attached to the floor the central plate will rest upon the end clamping-plates, as shown in Fig. 1. To this end recesses 23 are made in the central portion of 'each section of the body, as shown in Fig. 4, into which recesses the central plate 19 is introduced. Under this arrangement the upper faces of the several lugs 15 and 16 may be in the same horizontal plane.

When the device is to be used upon a ceiling, in order that the ceiling shall not be unduly marred or broken the screws 14 are not carried into the ceiling, as heretofore stated. Instead of screws clamps E are employed, these clamps consisting of two upright members 24, each having a base member 25, the base members of the clamps being secured by screws 26 or other fastening devices to the central lugs 16. The upper portions of the members of the clamps diverge, and at the upper extremity of each member or section of a clamp a toothed jaw 27 is formed, the jaws facing in direction of each other.

In the application of the device to a ceiling a suitable opening is made at opposite sides of the casing C to admit the, clamps, and the body portions of the clamps are forced upward, receiving between their sections or members the casing C, the jaws 27 of the clamps firmly engaging with the casing by reason of the clamp being made of springsteel or a similar material, as is fully illustrated in Fig. 4C. The clamps Will have sufficient hold upon the casing to maintain the device in the position required. In order that the clamping-plates shall not have sufficient play to cause such displacement as to produce an opening in the device, projections 28 are formed upon the several clamping'- plates, which by engagement with the walls of the opening 12 in the body-plate will limit the side movement of the clamping-plates.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Ina pipe-collar, a skeleton body-plate, clamping-plates having pipe-receiving openings, each clam ping-plate being provided with a cut extending from an edge to the pipe-receiving opening therein, and means, substantially as described, for holding the clampingplates in the body-plate, as and for the purpose specified.

2. In a pipe-collar, the combination, with a body-plate, of clamping-plates adjustably held in the body-plate, the said body-plate being provided with pipe-receiving openings, and cuts extending from the said openings to the outer edge of the several plates, as and for the purpose speciied.

3. The combination, with a body-plate constructed in detachable sections, the said sections being provided with lugs, of clampingplates held to slide in the body-plate between the said plate and its lugs, the clampingplates being of a ,spring material and provided with pipe-receiving openings, and cuts leading from the pipe-receiving openings of the plates to the outer edge thereof, for the purpose specified.

'4. A pipe-collar consisting of a bod y-plate constructed in removable sections, and clamping-plates adj ustably and removably held in the body-plate, the clamping-plates being of a spring material, end clamping-plates being mounted to slide in engagement with a central clamping-plate, each clamping-plate having a pipe-receiving opening, and each clamping-plate being likewise divided at a portion in its surface, the division extending from the pipe-receiving openings to the outer edges of the said plates, as and for the purpose specified.
