T all whom it may concern:

Beit known that I, ANDREW F. IIOWE,a citizen of the United States, residing at Granite Oity, Madison county, Illinois, have invented a certain new and useful Improvement in Wheel-Tempering Apparatus, ofwhich the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure 1 is an elevational View partly in section. Fig. 2 is aplan and sectional view, and Fig. 3 is a front elevational view of the apparatus looking toward the heating chamber or furnace.

The object of the invention is to produce an apparatus designed especially for tempering the rims of car-wheels, though it may be used for tempering other articles; and it consists in features of construction andrcombination of parts, all as hereinafter more fully described7 and specifically pointed out in the claims.

Referring to the drawings, A is a suitable base upon which is erected a heating-chamber 1, formed with an opening 2 in the front portion thereof, to which opening there are applied the

doors

3 and 4. To the upper portion of door 3 are connected chains 5, which are secured thereto by means of the eyes 6, while corresponding eyes G upon the lwer door 4 are used to connect said chains at the lower ends. Said chains pass over sheaves or pulleys 7, whereby said doors are balanced, while the weight S, connected to the chain or rope 9 and to said door 3 by means of the loop or eyelet 10 and passing over the sheaves 11, also counterbalances said doors and aids in opening the same, said sheaves 11 being supported above the heating chamber by brackets 12, as shown. It will be understood that the heating-chamber, or so much thereof as comes into contact with the products of combustion, is built of refractory material, such as fire-clay, rbc. Connected vat the upper left-hand end of the heating-chamber is a burner 13, (represented conventionally,) which burner is adapted by means of a blast to project a flame into and through the iiue 14 of said heating-chamber, which iiue follows a circular path, preferably about the diameter of a car-wheel, whence it turns and lextends upwardly, as shown, so as to connect with a chimney-flue, (not shown,) by which is carriedoff the spent products of combustion. The curved line 14 is inclosed upon all sides,

so that no flame will impinge the rim of the i are plates 20, to which are bolted iianged eX- tensions 21 of collars 22, within which latter is held the revoluble shaft 23, which latter is larger, preferably, within said collars and has upon its outer (the left-hand) end a sprocket-wheel 24, adapted to be driven from any suitable source-of power (not shown) for the purpose of revolving said shaft. The

enlargements 25 of the shaft 23 may be integral therewith or `may consist of collars shrunk in place, and thereby held fast to said shaft. Near the furnace end of said shaft 23 and either integral therewith or secured thereto is a double-coiled member provided with the coned face 26, shoulder 27 and retreating face 2S, the face 26being adapted to enter the axle-opening of a car-wheel 32, which car-wheel will abut against the shoulder 27, while a second conical member 29 is placed upon the end portion of the shaft adjacent thereto, where it is lheld by the nut 30, screwed upon the projecting portion 31 of said shaft, whereby the wheel is clamped in position.

Between the heating chamber or furnace and the base B isa depression or well, within which is located a hydraulic or other operable lifting device 325, vwhich carries a receptacle Y IOO rim is immersed in the tempering liquid therein, during which immersion the wheel is rapidly revolved with the carrying-shaft 23, so as to quickly present its entire peripheral face to the action of the teml'iering liquid, which latter will be carried in thin layers upon the rapidly-revolving face oi said wheel until the same is sufficiently influenced thereby, whereupon the receptacle Si is lowered and the lever 36 is thrown back, carrying with it the link 37, connected to the under side of one of the collars 22, and retraeting the carriage composed of said collars and the plates 20, to which said lianges 2l are secured. rlhe wheel and shaft in this retracted position will occupy substantially the position shown in dotted lines in Fig. l, though it will be understood that there is sufcient clearance to permit the removal of the wheel from the shaft, which is accomplished by first unscrewing said nut 30, removing said conical bearing member, after which the wheel is readily removable. Owing to the intense heat produced by the blast within said iiue it is desirable to have as large a working opening on the rear side of the furnace as possible to afford ready access to the members on that end of shaft so I there provide the circular opening 3S, through which access is afforded to the nut 30 when desired for manipulating the same. Said lever 36 is pivotally connected at ll0 to the arm 4l, which in turn is pivotally held within the yoke 4t2, so that the lever is free to operate to advance or retract the shaft 2.3, as desired. The driving-sprocket 2i is supported in position and fast to the collar 44, which latteris provided with a circumferential way or channel 45, in which is held the yoke 4G of the bracket 4-7, while a key 4S projects into a longitudinal groove 49, formed in said shaft 23, whereby independent longitudinal movement of the shaft is permitted while being driven from a iixed source of power, as shown in Fig. l in dotted lines.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Iletters Patent, is-

1. In an apparatus for tempering the rims of wheels, revoluble means for supporting the wheels, and means for moving the same longitudinally; substantially as described. 2. In an apparatus for tempering the rims of wheels, revoluble supporting means in line with a heating-chamber, and means for moving the same in the line oi its axis; substantially as described.
