This invention relates to that kind of 'means for supporting spring floors which comprises rubber supporting blocks mounted in sockets in a floor beam supporting member having below the level of the top of the rubber blocks a supporting surface for the underside of the beam to rest on.

The object of my invention is to provide a novel construction of the said means which enable the degree of spring to be readily suited to requirements, is light and easy tohandle and can be mass-produced cheaply and with great accuracy.

Means of the said kind for supporting floors in accordance with my invention comprises a beamsupporting plate having bosses projecting from its upper surface, each of the said bosses having a cylindrical vertical hole or socket which extends through the said plate and the top of the boss and is of smaller diameter at the upper end and contains a non-resilient spacing disc or block arranged between the said upper end and the top of the rubber block mounted in the said hole or socket.

We attain the said object by the means illustrated in the accompanying drawing, wherein- Figure 1 is an end view, partly in section of a resilient support for floor beams.

Figure 2 is a plan view of the said support.

Figure 3 is a plan view of a resilient support for floor beams and illustrates another construction.

Figure 4 is a fragmentary view in cross-section on a reduced scale of a floor showing two supports in use.

Referring to the drawing, in the construction shown in Figures 1 and 2, l is a metal plate which has two bosses 2 cast integrally with its upper side and projecting upwardly therefrom. The bosses 2 are spaced apart sufficiently to permit a floor beam of standard upright rectangular cross-section and standard cross-sectional dimensions to rest between them with the upper surface of the beam at a slightly higher elevation than the top surfaces of the bosses 2 so as to provide a small amount of clearance between the said top surfaces and the under side of the floor boards supported by the beam. A'fragment of the beam is indicated in dot-and-dash lines in Figure 2. The beam sits on the plate I between the bosses 2 and is secured thereto by nails or screws engaging holes 3 in known manner. The plate I is of greatest width where the beam sits on it and lessens in width towards its ends. The plate I can be made comparatively thin without danger of breakage due to its form and the 1 presence of the bosses 2 above it.

Each boss 2 has a cylindrical hole4 which ex-' tends through it and is continued through the plate I. The hole 4 has a portion 5 of reduced 5 diameter to form an annular shoulder 6 In each hole there is inserted a cylindrical disc or block 1 of wood or other comparatively non-resilient but non-squeak producing material of less diameter than the main portion of the hole 4. 10 The disc or block 1 is prevented from passing upwards through the hole by the annular shoulder 6. A cylindrical block 8 of resilient rubber is inserted in each hole 4 with its upper end abutting against the disc or block I therein. Its lower end forms a supporting foot in the usual manner.

Supports of the hereinbefore described construction are arranged in the usual manner at suitable distances apart beneath each floor beam to rest on the ground or sub-floor and support the beam.

The support is light in weight and yet of ample strength for its purpose. It therefore is not costly to produce and adds a minimum of weight to the parts sprung by the rubber blocks and consequently does not materially increase the inertia of the said parts and produce sluggishness of response of the floor to the shifting weight thereon.

The extension of the holes 4 through the tops of the lugs, by permitting the cores used in casting to be firmly held at both ends, enables true and perfectly vertical holes 4 to be produced by casting with great regularity and certainty. Consequently a correct fit of the rubber blocks 8, which due to their cylindrical shape can be produced with a maximum of economy, is ensured without adjustment of the holes after casting and the verticality of each block relative to the plate is ensured. The reduced portion 5 of the hole 4, permits the free entrance and escape of air from the upper part of the hole 4 and thereby makes for perfect freedom of the rubber block 8 to contract and expand as required. The disc or block I does not make an air-tight junction with the shoulder and therefore does not prevent the said entrance and escape of air. The inter- 7 position of the disc or block 1 between the top of the block 8 and the shoulder 6 avoids the damage to the top of the block 8 which would occur if the weight were transmitted by the annular shoulder 6 direct to the block 8.

The hole 4 enables a rubber block 8 of maximum length and therefore maximum resiliency to be employed, and employment of a. disc or block I in each hole enables similar castings to be employed for floors having difierent degrees of springiness or different heights above the ground or sub-floor, because by employing discs or blocks 1 of different lengths, rubber blocks 8 of different length can be substituted in the same casting to give diiferent degrees of resiliency of support, or blocks of the same length can be employed in producing floors of different heights.

The construction shown in Figure 3 differs from that shown in Figures 1 and 2 in the provision of three integral bosses 9 on the upper side of the plate l0 and in the shape of the plate N3, the Width of which lessens at one end only. The arrangement of holes in the bosses 9 and plate l0 and of disc or block is the same as that described with reference to Figures 1 and 2.

Figure 4 illustrates the use of the supports, the construction shown in Figures 1 and 2 being taken in Figure 4 to illustrate the said use. The supports are seen in Figure 4 in endview similar to Figure 1. The lower ends of their blocks 1 rest on the sub-floor II and the said blocks support the bosses 2 with their plates I clear of the sub-floor there are as many as is necessary, arranged parallelly and each supported as shown in Figure 4.

I claim-- Means of the hereinbefore specified kind for supporting spring floors, wherein the said means comprises a beam-supporting plate having bosses projecting from its upper surface, each of the said bosses having a cylindrical vertical hole or socket which extends through the said plate and the top of the boss and is of smaller diameter at the upper end and contains a non-resilient spacing disc or block arranged between the said upper end and the top of the rubber block mounted in the said hole or socket 7 JAMES FRANCIS BUCKLEY.
