IMPROVEMENT IN TURN-BUTTONS FR STOVE--DOORS Specification forming part of Letters Patent No. 167,853, dated September-Q1, 1875; application led July 6,1875. I

tain new and useful Improvements in Stove- Doors, of which the following is a specification, reference being had to the accompanying drawing, in which- Figure l is a view of the outside, and Fig. 2 a view of the inside, of a stove-door and its casing fastened together, and embodying this invention. Fig. 3 is a partial section of a part of the same, on a larger scale, at the line z z,- and Fig. tis a like section, but with the fastening turned so as to release the door. Fig. 5 is a partial section of the same, on the saine enlarged scale, at the line y' y in Figs. 2 and 3, and viewed in the direction of the arrow 5v. Figs. 6, 7, 8, 9, and 10 are views of parts of' the device shown in Figs. 3, 4, and 5. Fig. 1l is a sectional view of a part of a stove-door secured toits casing, and showing a portion of my invention in a modilied form; and Fig. 12 isA a plan of a part of the same below the line w w. Fig. 13 is a sectional view of a part of a stove-door and its casing secured together, and showing one form of a part of this invention. Fig. 14 is a sectional view of a part of va stove-door and its casing, secured together' by a turn-button of the kindheretofore commonly used.

Like letters refer to like parts in the dierent figures.

ln the turn-button heretofore often used on stove-doors, and shown in Fig. 14, a round stem extends through, and turns in, a socket through the door, and has a hand-piece and collar fast on the stem on the outer side of the door, and a finger fast on the stem on the inner side of the door, and arranged to engage with, and be disengaged from, an inclined bearing on the casing of the door, so

Y as to thereby fasten and unfasten the door on the inside by turning the stein by its handpiece on the outside. In such cases the collar end of the hand-piece bears directly and rigidly against the outer side ofthe door, and the button-nger is rigid o'n the stem, so that it is very difficult to fit the same to the door and to the inger-bearing on the door-Casin g, and so that the device turns hard in fastening the door, and will not hold the door' tightly closed whenever the parts are not very accurately' iitted together, or become much Worn; and, by reason of the direct bearing of the handpiece collar against the door, the handpiece is liable to be highly heated, so as to burn the hand of a person taking hold of it in fastening and unfastening the door.

To overcome or lessen the aforesaid defects is the primary object of this invention; and I accomplish that object by having the stein A extend through, andformed so as'toturn and slide endwise within, the socket b through the door C, and with the iin ger D fast on the stein on the inner side of the door, and the collar E and hand-piece F fast on the stem outside and away froml the door, and with a spring, G, surrounding the stem, and compressed between and against the door and the collar on the stein, and the whole constructed andarranged so that very little care or accuracy is required in iitting the parts together, and so that, by reason of the yielding of the spring Gr, and theendwise Inovability of the stern A, the latter can be easily turned so as to engage the finger D with any suitable inclined part or bearing h on the door-casing I, and so that the reaction of the compressed spring Gr will then keep the door tightly closed, but will still permit the stem A to be easily turned, so as to release the finger D from the bearing h, and so that the spring G shall also constantly isolate the collar E and hand-piece F from the door C, and thereby effectually lessen the heating of the hand-piece.

Fig. 13 shows the spring G exposed to View, and unconned on its outer sides, andwith the stem A supported wholly by the one socket b near one end of the stem, so that the spring G, when formed of ordinary rough steel wire, as usual,.would present an unsightly appearance in connection with the usually polished and plated hand-piece F, andthe stem A would be liable to wabble unless the socket b should be made longer than is desirable.

To overcome those defects is the object of a part of my invention; and I accomplish that object by means of the shield-piece or socket J, which extends outward from the door, and incloses the 'spring Gr laterally, and forms a lateral socket-bearin g at k for the collar E of the stem A, so that the latter may be snpported by the two bearings, b and 7c, one at each end of the spring.

In Fig. 11 the part J is shown4 in one and `the same piece with the body of the door C,

, thereby produce friction, and somewhat affect the strength or action of the spring by torsion of the latter.

To overcome those. defects is the principal objectof a further part of this invention, which I attain by making the shield-socket J, socket b, and bearing fm, for the inner end of the spring G, all in one separate thimble-piece, L, and tted into, but not quite through, the socket n in the door-body, and retained, so that it may turn therein, by the reaction of the compressed spring G in connection with the stem A, and its finger D bearing against they inner rim o of the socket n, as shown in Fig. 4, or against the bearing h of the doorcasing, as represented in Figs. 2, 3, and 5.

Inv Figs. 6, 7, 8, and 9 the finger D, thimble L, spring Gr, and stem A, with its collar E and halrlid-piece F, are shown separate from` each ot er.

In Fig. 10 the stem is inserted in the spring I in the thirnble L ready to be inserted in the socket u in the door-body, and after such insertion the iinger D is to be fastened to the inner part of the stem A by riveting down the end of the latter, as indicated at p in Figs. 3, 4, 5, and 13, or by a screw and nut, as represented at q in Figs. 1l and 12, or by any other suitable means.

What I claim as my invention is- 1. In combination with a stove-door having the socket b therein, and door-casing having the button-bearingh thereon, the turningand endwise-moving stem A, with its button-iinger D, collar E, hand-piece F, and spring G, all arranged to operate as shown and described.

Y2. In combination with a door having the socket b, and doorcasing having the finger! bearing h, the turning and sliding stein A,

with its nger D, collar E, and hand-piece F, the spring Gr and the shield-socket J, all arranged together substantially as shown `and specified.

3. In combination with a door having the socket b in a turning thimble, L, Fig. 3, in the socket n in the door, the stem A, with its finger D, collar E, and hand-piece F, and the spring Gr, surrounded with the collar by the thimble, and all arranged to operate as shown and described.
