19 Claims.

This invention relates to casters and has particular reference to one designed for use on the floor of a hearse for the easy and quiet operation of the casket table thereon.

Caster devices for use under casket tables have heretofore been so constructed that it was necessary to drill large holes in the floor to mount the same, owing to the fact that there is very little space between the floor and the bottom of the table. These earlier casters, furthermore, did not give true anti-friction operation in all directions and the tablewould actually slide instead of roll on certain of the casters, with the result that the operation of the table was not as quiet and easy as desired. It is, therefore, the principal object of my invention to provide a new and improved caster which, besides being so constructed that it will give true anti-friction operation in all directions of table movement, is of such compact design that the entire assembly is above the floor line and may be fastened to the floor by screws, instead of having to be set into the floor.

In the carrying out of my invention, I provide a roller for the table to operate upon and this roller is set in a revolving support to one side of the center thereof so as to give a true caster action-the roller being arranged to come into line automatically with the direction of movement of the table. The center of the roller is, furthermore, in the same planewith the ball bearing for the revolving support, thus eliminating any tendency whatever for binding and making for the best obtainable compactness. The construction is also substantially dust-proof, as hereinafter described.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a horizontal section through the body of a hearse showing the casket table therein with the casters indicated in dotted lines therebeneath and also shown in plan on both sides of the front end thereof;

Fig. 2 is a section on the line 2--2 of Figure 1 showing the caster in cross-section substantially full size;

Fig. 3 is a bottom view of the caster taken on the line 3-3 of Fig. 2 and showing certain parts broken away to better disclose the construction, and.

Fig. 4 is a sectional detail on the line 4 l of Fig. 2.

The same reference numerals are applied to corresponding parts throughout the views.

Referring .first to Figure 1, 5 is the casket table movable relative to the floor 6 along guides, not shown, either by hand using the handles '3, or by the operation. of power operated means, not shown, to extend the table from the hearse body 8 through the opening at either side afforded by the opening of the doors 9. The table, while moving along the guides into and out of the hearse, is arranged to ride on the casters it provided at the various points indicated in Figure 1.

Figs. 2, 3 and 4 illustrate the caster ill, as made in accordance with my invention. Briefly stated, it comprises a table supporting roller l l operating on a horizontal pintle l2 in an off-center hole H3 in a revolving support M that is carried on a ball bearing it on a base it suitably secured to the floor *5, as by screws ll. The line :cy in Fig. 2 indicates that the roller l l operates on'a center H2 in the same horizontal plane with the centers of the balls of the bearing it. In that way, the construction is made as compact as possible, being hardly any larger in over-all height than the diameter of the roller l i. This enables use of the caster in the small space available between the floor ii and the bottom of the table 5, and obviates the necessity for either recessing the floor or making a'hole in it, as was necessary heretofore. Furthermore, since the center 52 is not oiiset with relation to the centers it, there is no tendency for canting of the revolving support it when lateral thrust is imposed upon the roller ll, and consequently no likelihood of the parts binding. The extent to which the roller l l is offset from the center of the support M is indicated by the dimension 2 in Fig. 3. This eccentricity is sufficient to insure good caster action; the roller ll will cause the support it to turn immediately just as soon as there is any side thrust upon the roller l l due to a change in direction of movement of the table. As a result, the rollers ll of the various casters are always pointed in the direction of movement of the table and are accordingly allowing the table to roll thereon instead of sliding. The table will, therefore, move quietly and easily in every direction since it operates on anti-friction bearings at all times-it operates on the ball bearing it in the turning of the support M and on the ball bearing It in the turning of the roller l l.

The parts i l and it are, for the purpose of economy in construction, made as die castings. The pintle i2 is entered through a hole It in the central cylindrical boss 2% provided on the support it, there being a hole H in the depending rim portion 22, as indicated in Fig. 3, to permit such assembly. After the pintle is entered, a hardened race ring 23 for the ball bearing I 5 is placed in position located by an annular shoulder 24, as appears in Fig. 4, and then another hardened race ring 25 is pressed over the boss 28 to hold the ring 23 in place and also cover up the ends of the hole If). The balls of the bearing l5 operate between the ring 25 as an inner race and the rim 2% of the base It as an outer race, and between the ring 23 as an upper race and another hardened ring 2'! as a lower race. The ring 27 is supported in the base 86, as shown. An annular internal flange 28 on the base 55 has its bottom surface nearly in the same plane with the bottom of the boss 22) so that washers 29, fastened by screws 30 to the boss 20 and overlapping the flange 28, will serve to hold the assembly together, that is, keep the support it retained on the base It. An outwardly and downwardly projecting flange 3| is provided on the rim 22 to enclose the base it both for neat appearance and to exclude dust and dirt from the bearing l5. This construction necessitates holes 32 in the flange 3! to afford access to the screws I! when fastening the caster to the floor or removing the same. A finishing ring 33 of angular cross-section fits over the rim 22 of the support l4 and down onto the flange 3! to cover these holes 32 and at the same time cover the hole 2! in the rim 22 for good appearance and to further seal the bearing [5 against dust and dirt.

While the caster has been described as applied to use in a hearse for support of the casket table, it should, of course, be understood that the invention is not limited to that specific ap plication but may be employed wherever a caster of such compact design and easy running characteristics might be desired. Furthermore, while the caster is shown mounted on a stationary part to support a movable part, the arrangement might be reversed, if desired.
