FLOOR-PLATE.

Specification of Letters Patent.

Patented J an. 5, 1915.

Application filed January 30, 1914. Serial No. 815,344.

To all whom it may concern:

Be it known that 1, CHARLES FRANKLIN CHRISTIAN, a citizen of the United States, residing at New York city, in the county and State of New York, have invented new and useful Improvements in Floor-Plates, of which the following is a specification.

My invention relates to floor platesthat is, to plates used in connection with steam pipes or pipes of other kinds, at the points where the pipes extend through the floor or through the ceiling or a wall as the case may be, for the purpose of preventing direct engagement between the pipe and the member through which the pipe extends.

My invention, while admitting of general use and adapted for various purposes, is of special value in the case of steam pipes extending through ceilings and floors.

More particularly stated, my invention comprehends a floor plate made in halves, each half having the general form of a semi-ring, the two halves being provided with means for locking them together and holding them when thus locked, the semiring being further provided with means for detachably holding it upon the pipe independently of any other part, and in such manner that, by separating the two halves of the ring, it may be instantly disconnected from the pipe.

My invention further contemplates the use in connection with the semi-rings, of spring fingers having such form and so located as to prevent the floor plate, after being placed in position upon the pipe, from creeping in the general direction of the length of the pipe, owing to expansion and contraction of the pipe due to changes in its temperature.

Reference is made to the accompanying drawing forming a part of this specification, and in which like letters indicate like parts.

Figure 1 is a perspective, showing my device as employed in two separate relations that is, in connection with afloor and in connection with a ceiling. Fig. 2 is a perspective, showing the two halves of the floor plate as separated from each other.

Two semi-rings 3, exactly alike, are each provided with a substantially semicircular outer flange 4, and a substantially semicircular inner flange 5. Each of the semirings 3 is further provided with two locking plates 6 and 8, which extend flush with the outer or free edges of the flanges 4: and 5. The locking plate 6 is provided with a slot 7, and the locking plate 8 carries a V-spring 9 made in this instance of a' single piece of spring wire, and bent at 10 so as to form a notch.

The V-spring 9 of each semi-ring 3 mates a slot 7 of the opposite semi-ring in such manner that when the two semi-rings are brought into registry, each V-spring 9 readily enters the slot 7 mating it, and when this is done, if the two semi-rings be forcedtoward each other, the bent portions or notches 10 of the V-springs, by engaging the adjacent portion of the locking plate 6, securely hold the semi-rings together, as shown in Fig. 1. Each semi-ring is further provided with two spring fingers lll2, carried by the flange 5, and extending slightly oblique in relation to the geometrical axis of the semi-ring. Moreover the spring fingers 11 and 12 are bent slightly toward said axis, or in other words, they converge to some exten l/Vhen the two semi-rings are fitted around a pipe 13 and secured together as above described, and as indicated in Fig. 1, the spring fingers 11, 12, press firmly against the pipe, and thus secure the floor plate thereupon. In order to remove the floor plate from the pipe, the two semi-rings are simply pulled apart by hand.

The construction above described admits of the device being made easily and cheaply. All parts of each semi-ring except the spring 9, being integral, can be stamped, struck up, or drop forged, and thus easily formed. Again, if desired, they can be readily cast, or worked up in various ways from scrap material. The V-springs 9, owing to their simple form, can be rapidly formed one after the other in succession, from a single wire. The V-springs may be secured to the semi-rings by welding, brazing, soldering or by any other approved means for securing a small bit of metal to a larger body thereof.

The device, when complete and in position, presents a neat appearance and is not liable to get out of order. Either of the semi-rings may be removed and replaced independently of the other. That is to say, either semi-ring may be removed, and the remaining semi-ring will remain self-supported upon the pipe. This is because the spring fingers of each semi-ring are disposed substantially at opposite ends of a line representing the general maximum diameter of the pipe. the spring fingers thus located, the tendency of the floor plate to creep, in the general direction of the length of the pipe, owing to expansion and contraction of the pipe in consequence of changes in itstemperature, is completely avoided. The result is that my floor plate, being secured upon a pipe, will remain indefinitely in the position in which it is thus placed. As the semi-rings are exactly alike, they are interchangeable, and their manufacture is rendered simpler than it would be if they were unlike.

I do not limit myself to the precise mechanism shown, as variations may be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by- Let'- ters Patent is as follows:

1'. As an article of manufacture, a semiringprovided with a male looking member at one end and a female locking member at the opposite end, said male looking member consisting of a V-spring having the general form of an arrow head.

2. As an article of manufacture, a semiring provided with an internal arcuate flange and two diametrically opposite spring fingers oblique to the aXis of the Moreover, by having' semi-ring and integral with said flange, whereby said semi-ring may be sustained upon a pi p'e'by spring compression of said spring fingers upon said pipe, said semiring being provided with a V-spring at one end' having the general form of anarrow head, and at the other end with a slot.

3; A- fio'o'r: plate consisting of two semirings, each provided with a male locking member at one end" and a female locking memberat the oppositeend, said male looking-- members'consisting of V-spring's having the general form of arrow heads;

4; A floor plate consisting of twosemirings, each provided with an internal arcuate fiange and two diametrically opposite spring fingers oblique to the axis of the semi-rings and integral with said flanges, wherebysaid fingers of each semiring are adapted to impinge a pipe at substantially diametrically opposite sides thereof when the parts are' assembled, whereby said semi rings may be" sustained upon a pipe by spring compression of said spring fingers, said" semi rings each being providedwith a V-spring at one end and having "the general form of an arrow head, and at the other end with a slot.
