CASTER DEVICE FOR STOVE-LEGS.

Application filed October 27, 1915.

To all whom it may concern:

Be it known that 1, CHARLES G. OVER- MYER, a citizen of the United States, residing at Hartford City, in the county of Blackford and State of Indiana, have invented a new and useful Caster Device for Stove-Legs, of which the following is a specification.

The present invention appertains to caster devices for stove legs, and aims to provide a novel and improved appliance of that nature applicable to a stove leg, whereby the leg can be raised and supported upon a caster when it is desired to move the stove about, each of the legs of the stove being equipped with one of the devices.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a front view of the stove leg, with the caster device in normal position, the cover of the stove leg being swung open. Fig. 2 is a rear view of the leg with the caster lowered. Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1. Fig. 4 is an elevation of the wrench for operating the device. Fig. 5 is an elevation of a modified form.

In carrying out the invention, the stove leg 1 which is in the form of a casting, is provided with a suitably located opening 2, and rear lugs 34 at the lower and upper ends of said opening. The leg 1 also has a rear lug 5 at one side of said opening, and the leg is provided below the opening wlth a web 6 having an aperture or opening 7. The lugs 3, 4 and 5 and web 6 are readily cast integral with the leg. The opening 2 is normally closed by a cover or closure plate 8, which is pivoted, as at 9, t0 the exterior of the leg above the opening 2, whereby the cover 8 can be swung downwardly to close the opening, whereby the opening does not impair the appearance of the leg, but on the other hand, the closure 9 provides an ornament for the leg so that it is not objectionable. A vertical spindle or rod 10 is slidable through the aperture 7 of the web 6, and a caster 11 is swiveled t0 the lower end of the spindle 10 in any suitable manner, it being preferable to provide anti-frict1onal bearings for the caster, so that the caster Wlll swing readily about the vertical axis of the spindle 10. The spindle 10 has a flattened upper terminal portion 12 which rests snugly against the lugs 3- 1, and which is provided with an upwardly opening slot Specification of Letters Patent.

13 in rear of the lug 4. A retaining screw 14 is threaded into the lug 4 and extends through the slot 13, the head of the screw 14- hearmg against the rear side of the portion 12 to hold said portion slidably against the lugs. The spindle 10 is thus guided for vertical reciprocation within said leg, the leg housing the spindle and accompanying parts, so that they do not render the leg unsightly in appearance.

As a means for raising and lowering the spindle, an eccentric or cam 15 is pivoted to the front side of the portion 12 by means of a rivet or pivot element 16, and the eccentric 15 is disposed snugly between the lugs The eccentric 15 has a forwardly pro- JGCtlllg boss or lug 17 around the rivet 16, and said boss or lug is preferably of trapezoidal contour for engagement with the trapezoidal socket 18 of a wrench 19, whereby the wrench can only be applied to the boss 17 in one position. This provides for the proper application of the wrench to the caster device, so that said device can be operated readily and properly. The wrench is preferably in the form of the stove shaker, and is equipped with the socket 18 projecting therefrom for engaging the boss 17.

Ordinarily, the eccentric 15 which is carried by the spindle 10 is swung downwardly,

and bearing upon the lug 3, will raise the spmdle 10, to retract the caster 11 above the lower end of the leg 1. The leg can therefore rest on the floor or base. When it is desired to move the stove, it being understood that one of the caster devices can be used upon each leg, the cover 8 of the leg is swung open, and the Wrench 19 is then ap plied to the boss 17, so that the wrench projects to the left, as viewed in Fig. 1. The wrench is then swung upwardly through an arc of 180 degrees, and the eccentric 15 hearing upwardly against the lug 4, will force the spindle 1O downwardly, to project the caster below the lower end of the leg, whereby the leg will now be supported upon the caster. The eccentric 15 swings against the lug 5, which prevents the eccentric from swinging farther, and the eccentric is preferably swung slightly beyond dead center against the lug 5, whereby the eccentric will not turn back to normal position under the weight of the stove which is imposed upon the eccentric. hen all of the caster devices of the legs are lowered, the stove can be readily moved about, and to set the legs down upon the floor again, the eccentrics 15 are swung backwardly to normal position, so that the legs are let down onto the floor and the casters retracted. It is to be noted that the eccentric or cam is pivoted to the spindle and merely bears against the lugs of the leg, so that it is not necessary to pivot the eccentric to the leg itself, which would be objectionable in that it would weaken and probably fracture the leg due to the strains.

In the modified form illustrated in Fig. 5, the caster device is applied to the casing 1 of a stove adjacent the corner thereof, and upon the inner side of the casing. The device embodies acasting 1 attached to the stove casing 1, and having on opening 2, lugs 3 and 4 and an apertured ear or flange 6 resembling the similarly numbered parts above described. A spindle or rod 10 is slidable through the ear 6 and has a caster 11 swiveled to its lower end, the upper portion 12 of the spindle 10 having an upwardly open slot 13 receiving a screw 14 which is attached to the lug 4, the same as the similarly numbered parts above described. The eccentric or cam 15 is pivoted to the spindle 10, as at 16, and is disposed between the lugs 34, the casting 1 also having a lug 5' against which the eccentric 15 rests when the eccentric is swung upwardly. The modification illustrates how the device can be applied within the corner of a stove casing, to raise the casing off of the floor so that it can be supported by the caster, and in this form, the corner of the stove is equivalent of the leg 1 above de- Gopies of this patent may be obtained for scribed. The casting or plate 1 can be readily secured to the stove casing for applying the device thereto.

Having thus described the invention, what is claimed as new is:

In a device of the character described, the combination with a leg having an opening, a rear lug at the upper end of said opening, a rear lug at one side of said opening, and a rear web below said opening, of a removable closure in front of said opening, a vertical spindle slidable through said web and having its upper terminal bearing slidably against the first mentioned lug, the spindle having a caster at its lower end and a vertical slot in its upper terminal, a securing element extending through said slot and engaged with the first mentioned lug to hold the spindle thereagainst, an eccentric between said spindle and opening, a pivot connecting said eccentric and spindle, the occentric having a forwardly projecting boss around the pivot and adapted for the engagement of a wrench inserted through said opening, the first mentioned lug being scatable on said eccentric, and the eccentric being adapted to bear against the second 1nentioned lug when the eccentric is swung upwardly and slightly past dead center.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
