STOVE-CASTER.

.readily adjusted from a position where the stove rests wholly upon its own base to a position where the weight of the stove will be borne by the caster, and, second, to provide a caster that may be readily used either inside of the base of the stove, where the base is sufficiently clear of obstacles, or may be attached to the outside of the stove when ovens, partitions &c. are located in the base oi the stove near the bottom. I attain these objects by the mechanism illustrated in the accompanying drawing in which Figure 1 is a vertical section of a stove on the line :1; x of Fig. 2, showing the caster in place at the Sides with the connecting bars shown in section. Fig. 2 is the same on the line y y of Fig. 1 showing the casters set at the back oi the stove. Fig. 3 is an elevation of a stove showing the casters attached to the outside. Fig. 4 is a detailed view of the lever by which the casters may be manipulated. Fig. 5 is an elevation oi' the lever and eccentric with which the casters on the outside of the stove may be manipulated, and Fig. 6 is the same showing the eccentric inside of the stove and the handle outside.

Similar letters refer to similar parts throughout the several` views.

In the several views A represents the stove frame or side and B re resents the base of the stove. The casters are supported in pairs in vertical tubular posts D which are so se cured to the sides of the stove A that they may be readily moved up or down, as represented at l) b, and these posts are connected by a cross bar D. When these casters are used inside the base of a stove, as in Figs. 1 and 2, I provide for manipulating them to throw the weight of the stove upon or oiof from the casters C by means of a lever practically of the form shown at F in Fig. 4, so that the end may be passed through the hole f in the side A of the stove in such a manner that the end f will rest on the top of the Gross bar D in such a manner that when the Specification of Letters Patent.

lever F is raised to the position shown in Fig. 4 and indicated by the dotted lines in Fig. 1, it will force the casters down, as indicated by the dotted outlines of the casters in Figs. 1

and 2, so that the entire weight of the stove.

will be upon the casters and the stove may be readily moved thereon. lVith this construction it is necessary to provide some means apart from the levers for supporting the weight oi the stove when being moved, and

for this purpose I find the latches E E pivoted to the side of the stove A as at e, in position to drop back over the cross bar D when the casters are down in position to support the stove. Y

Then it is necessary to place the casters on the outside of the stove, as in Fig. 3, they may be secured to the stove A in much the same manner as when they are inside the stove, though, of course, it will require greater care and better finish to make them sightly. While the caster posts may be manipulated with the levers F, if desired, I find that an eccentric, as shown at G in Figs. 3 and 5, formed With a body G that may, or may not be grooved, as at g to form a bearing upon the cross bar D. The eccentric bearing g is designed to pass through a small aperture in the side A of the stove in such a position that when the handle G of the eccentric G is in its normal position, shown lin Figs. 3 and 5 the casters C will be up and all Weight of the stove will be removed from them, but if the handle of the eccentric is swung down to the position indicated by its dotted lines in Fig. 3 the casters will bc forced down, which will cause the stove to rise up with its entire weight .upon the casters so that the stove may be moved without diiiculty, as hereinbeiore stated..

To avert all danger of the eccentric being thrown around by the weight of the stove I find it advisable to ilatten the top or large side oi the eccentric body as indicated by the dotted lines o in Fig. 3, thus providing a square bearing upon the cross bar Dl so that it will require some exertion to turn the ec'- centric over its corners, thus insuring the stability of the casters when bearing the weight of the stove.

The handle G is a necessary appendage upon the eccentric, but the hand piece g may be dispensed with without great detriment to this appliance, and it is designed to make the eccentric readily removable by simply removing the bearing g from the aperture in the side of the stove, hereinbefore mentioned. The concave bearing g in the body G of the eccentric is very desirable as it absolutely averts the danger of the eccentric slipping H of the cross bar D or of the bearing g being drawn out of its aperture in the side of the stove.

If desired the eccentric may be used for the inside attachment of the casters by reversing it from the position shown in Fig. 5 and securing the handle G/ to the central bearing g, as shown in Fig. 6, and I prefer that this connection be made by passing an arm, as c from the side of the handle G', through the center of the bearing g', though it may be attached by any of the well known mechanical means of attaching such handles, cranks or arms, as may be.

If desired, and I find it very convenient, the crossbar D may be placed higher up on the posts I) so that both of the straps b b on each post may be laced below the crossbar, which will enable t e operator to remove the posts and casters from the stove without difficulty.

Havin thus fully described my invention, what I cIaini as new and desire to secure by Letters Patent of the United States, isz- In combination with a stove, a vertically adjustable frame consisting of posts and,a cross-bar connecting thel posts, guides secured to the stove above and below the said cross-bar for supporting the posts and allowing of their free vertical adjustment, an eccentric revolubly secured to the stove frame in position to act upon the cross bar to force the frame downward, said eccentric being flattened at the point of maximum throw to rest upon the cross bar and support the weight oit' the stove without danger of turning the eccentric and allowing the stove to drop, a crank passed through the stove frame for actuating the eccentric, and casters sup orted in the lower ends of the posts.
