UNITED STATES PATENT OFFICE.
ROBERT SCOTT, OF GLENSIDE, PENNSYLVANIA.
FIREPROOF PIPE-SLEEVE.
SPECIFICATION forming part of Letters Patent No. 576,899, dated February 9, 1897.
Application filed March 3, 1896. Serial No. 581,681. (No model.)
tion of pipe-sleeve which is made of suitable c. fireproof material and provided with openings extending longitudinally therethrough, provision being made for holding said sleeve in proper position relative to the ceiling and floor and for retaining and guiding therein the pipe to which said sleeve is applicable, all as will be hereinafter set fort-l1, and specifically pointed out in the claim.
Figure 1 represents a perspective view of pipe-sleeve embodying my invention. Fig. 2 represents a vertical sectional view of said sleeve placed in position with a portion of a floor and ceiling and fastening devices applicable to the same, the section being taken on line mm, Fig. 3; Fig. 3 represents a plan View of Fig. 2.
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawings, A designates a pipe-sleeve, the same consisting of the body portion B,whicl1 may be rectangular or other shape, and h as extending longitudinally therethrough the passage 0, through which the pipe L passes.
D designates openings extending longitudinally through said sleeve in substantially parallel direction to the passage 0.
E designates a portion of a ceiling, and F designates a portion of a floor, to which said pipe-sleeve is applicable.
G and H designate floor and ceiling plates, respectively, which are held in position relative to the fioor, ceiling, and sleeve by means of the bolts K, each of said plates having an opening M therein from which extends inwardly the spurs or projections J, which abut against the pipe L and serve to hold the latter in position when the parts are assembled.
The manner of assembling the parts is as follows: An aperture having been out in the fioor and ceiling F and E, respectively, of sufiicient diameter for the insertion of the sleeve A the same is placed in position, so as to inclose the pipe L. The plates G and H are then placed in position over the ends of said sleeve, so as to contact with the floor and ceiling, respectively, and are held by means of the bolts K, which pass through said openings on the plates and the openings D in the sleeve, the pipeL being held in position relative to said plates and to the sleeve A by means of the spurs or projections J, the caps G and H being preferably made in sections, as indicated in Fig. 3.
It will be seen from the foregoing that by my invention a cheap and serviceable fireproof pipe-sleeve is produced which reduces to a minimum the danger of fire and is at the same time easy of access and readily placed .in position.
ROBERT SCOTT.
