eminence APPARATUS.

To all whom 'it may concern.' g

Be it known that I, FRED H. DANIELS, of VVorceste'r, Worcester county,.Massachusetts, have invented a new and useful Improvementin (hargin'v Apparatus, of which the following is a fu, tion,ireference.being had to the accompanyfication, in which v l y Figure l is a plan view of a billet-charging apparatus embodying' my invention; Fig. 2 is a longitudinal sectionof thesame; Fiv. 3 is an end elevation.

l/[y invention has relation to apparatusy for charging heating furnaces-and is de'- signed to provide apparatus of y'this' character -which will always be in condition Ato operate regardless of weather conditions and which isl so arranged as topi-Ovide for the storage of billets or other blanks at the extreme end of the apparatus, which may be outside of the building in the storage yard of the plant, thus saving room in the building itself. y

Other objects and advantages of the invention will hereinafter appear.'

In the embodiment of my invention shown.

in the drawings, I have lindicated a'double width fur-nace'2, together with two 'inde-l 4veyer, preferably a car 6,'running on the'.

tracks 7 arranged transversely. at thel outer end of the apparatus.

8 designates the pusher bar having hinged l to its outer end an arm 9, which, upon-thel forward stroke of the bar 8, is arranged' to engage the billets on the car, as indicated in Fig. 2, and push the same on to the slideway 4, the arm being held rigid during this movement of the bar by its engagement with the shoulder 10 thereon. During the reverse movement of the bar, the a'rin swings out of the way and slides over the'bille'ts until'the end of the row is reached. The bar is actuated by means of a rack 11, secured thereto and engaged by a pinion 12, on a shaft 13,

clear, and exact descrip-I driven through the chain y.of gears 14,"f01'ming the slow-down gearing, by an electric motor 15. The bar 8 is suspended at one end by the wheels or rollers 16, which travel'on Patented May 3, 11910.

are su ported from "the vfurnaoe'2, as in dicate at 19. The pinion 12 also forms fa' su port for 'the bar, and ai roller 20 vjour-l -naledvon the xed franiefmember 21 and bearing on' the .upper surface of the4 bar,f. serves to take the upward .thrust yfrom-the gears.

The operation will be readily understood#` When' the motor 15 lis operated, the arm 8 isreciprocated and Aeach forward stroke pushes aseries of billets from. `the car 6 on to the sl'idewayJl, at the same time moving the entire series of billets continuously alon the slideway and through the furnace whic j is of the continuous type. During the reverse movement of the pusherbar, the arlnv 9 slides freely over the supports in theman-,f-

ner before described. y 4 l i :The shafts of the two motors may becon-4 nected, if desired, as shown in' Fig. 1.V The advantage of connecting the shafts ofthe two motors .in this 'manner is that the two'f pushers may be made to act- `as one, in'qcase long` b1lletsare, charged luto the furnace,

that is to say, the 'two racks will travel tol' gether in the same direction'. and at the 'same time, and thefbillet which extends 'clear'- across the `furnace, or which is twice. the length of the billets ordinarily used, can be charged through the furnace.

The 'advantages of my invention will be apparent to those skilled inthe art. The,

customary way heretofore of charging a' bilp let-heating furnace has been by means of af' hydraulically-operated pusher, which forces a numbero billets into the'furnace from a car placed between it and the usher or from a stationary support on whic layers of bil. lets are successively placed, by means of a suitable overheadicrane. The serious disadvantage of this .arrangement is that 1n vcold weather), the pusher 1s liable to be rendered; inoperative, dueto freezing lof the f water.. As the furnaces should be placed4 Y inside the buildinglbut as near the outside 4 e, the useof a hydraulic billet yard as poss pusher `of this common type necessitates either running the track for the carsinto.

' .building itself. l@

lt Will be obvious that various changes may be made in the details of lconstruction andarrangement of the several parts, Without departing from the spirit and scope of my invention,"as defined in the appended claims.v Flhus, the manner of supporting the pusher bar may be changed, any suitable arrangement .of actuating gearing between the motor and the pusher har may be lemployed, and various other changes may be made. The pusher bar and arm or linger may also bel actuated Aby other means, such as a hydraulio or pneumatic cylinder placedover the billet slidevvay, and inside the building. lnstead of employing the apparatus with a double Width furnace, tivo single Width furnaces maybe used when preferred but to move one charging mechanism being employed with each furnace in such case, andA the chargin mechanisms may be connected so in unison or not is desired.

l claim:` q l 'll-Furnace charging apparatus comprising a reciprocating pusher bar having means arranged to contact with and push blanks supported beneath said bar into the furnace, a track for said pusher bar, a rotary driving motor and gearing operatively connectings-aid motor and pusherbar; substantially as described.v

' 2. Apparatus for charging furnaces comprising a slide-way on which blanks arc transferred to the furnace, a reciprocating pusherarranged to travel above the Slideyvvay and having a pivoted pusher arm contacting with said blanks, a rotary driving 'motor and gearing operatively connecting said motor vvith the pusher; substantially as described.

3. Apparatus for charging furnaces comi prising a supporting slide-Way for the blanks, a pusher bar arranged to reciprocate over and above the slide-Way, said bar having a toothed rack attachedthereto, guides for the bar, a rotary driving motor and gearing operatively connecting said motor In both senseo with the rack y on said bar; substantially as described. f

4. Apparatus for charging 'furnaces com- ,f

prising a slide-way on which blanks are supported, a track adjacent thereto, a pusher bar arranged to reciprocate over the slide- Way and track having la pivoted pusher finger adapted to contact with the blanks, a rotary driving motor and gearing operatively connecting the motor with said pusher bar; substantially as described'.

5. Apparatus for charging furnaces comprising a slide-way onwvhich the blanks are supported and moved into the furnace, a track above the slide-Way, a reciprocating pusher bar mounted upon vand adapted to travel on said track, said pusher bar having a toothed rack secured thereto, a rotary driving motor and means operatively connecting the Amotor with .the rack on said pusher bar; substantially as described.

6. Apparatus for charging furnaces comprising a support for the blanks to be charged into the furnace, a reciprocating pusher bar, a pusher finger connected tot-he bar arrangedto contact with the blanks and means for reciprocating the pusher bar and linger above said slide-Way; substantially as described.

7. Apparatus for charging'furnaces comprising a slide Way on which blanks are ymovably supported, a reciprocating pusher bar above said support, a pusher finger pivoted to said bar, said finger being free to swing in one direction and means for reciprocating said bar above the supporting slide- Way and moving materials supported on the slide-Way forwardly toward the furnace; substantially as described.
