To all who/n may col were.

Be it known that 1, Pain. A. hirer-iiiis citizen of the United States, and resident New Castle, in the county of Lawrence and State of Pennsylvania, have invented oertein new and useful improvements in. Car Movers for ilunnel-Kilns, of which the following is e. specification.

My present invention relates to tunnel kilns of the type in which the goods to he treated by the kiln are mounted on trucks or cars a train of which normally fills the kiln or the body portion thereof and this train is periodically advanced a car length at a time as fresh cars are. inserted one after another at the entrance end of the kiln, by some sort of our pushing mechanism which ordinarily engages the rear cor oi the train.

, In kilns of this character it is "frequently necessary to advance the forward car of the train to separate it from the main train oi cars behind it and by means of which it has been brought into its forward position. For example, in many tunnel kilns the :lorwerd goods carrying car of the train must he so arated from the lhitlfi of the trein at the exit end of the kiln in order to ren'love this forward car from the molin stationery track in the kiln onto a movable track mounted on e transfer or turn table preparotorv to moving the forward car laterally awe}; iroin the kiln. Vaherc the kiln has at its exit end an exit chamber with an egress door from this chamber to the external atmosphere, and a second door between the chem-- her and the body of the kiln so as to vide an air look permitting the removal of cars Without establishing free coinniunicetion at any time between the body of the kiln and the external atmosphere, it is necessary to advance th forward car and separate it from thelood i' of t e train of cars in order to permit the closure of the door between it chamber and the body of the kiln after the forward car has been moved into the exit chamber.

The general object of present invei tion is to provide simple and efieeti'vc insane for separating a forward car "from the fol lowing cars of the train moving through the tunnel lriln when conditions such cstion of Letters 1 or the escape of the kiln atmosphere to the external atmosphere. Adventsgeously I may provide means actuated by the move mentoi"? the cars for indicating when the ear advancing; means should be operated on Where the cor advancing means are power actuated I may provide automatic means for setting the cor advancing means into operation end for stopping its operation I'FlEQRO Bl the mo ement of the cars rushes this desirable.

The Vz'i'iiods features of nov lty which characterize in; invention are pointed out with. particularity in the claims annexed to and forming it part this specification. For a better understeiidin of the invention, however, and the advantages possessed by it reference should be loud to the accompanying drawings and descriptive ineiiter in which I have illustrated and described various embodiments of my invention.

The forwardcar in the train of cars in the body of the kiln is periodically moved past the door l) with the latter in its open position onto a transfer table 'F after which the door D is closed and the door E opened and the transfer table then moved along the track rails G to bring the car into the position from which it may be moved oil the transfer table onto the return track 1. Subsequently the turn table F is returned to the exit chamber, the door E is closed and the door D is opened so that the then forward car in the train may be moved onto the transfer'table- The mechanism provided in accordance with present invention as shown in Figs. 1. t2 and 3 for separating the forward car (3 from the train of cars 0 filling the body oil the lriln and advancing this forward car to center it on the transfer table F, cornprises. a reciprocating element K passing through a stufiing hot: or hearing A in the end wall of the kiln. The bar K is formed at its inner end with a hook K adapted to engage the rear side of a lug-"C formed on the under side of the car body when the hook: is raised as shown in Fig. 2. The bar K may be rotated however to turn the hook into a horizontal position and thereby to permit the passage of the hook beneath the lug C preparatory to engaging the latter. To rotate the bar K the latter is provided externally of the kiln with an oper- To reciprocate the bar K the latter is swiveled to a reciprocating element in the shape or a rack bar form in; a part of a jack L shown as comprising gearing and a crank arm L for'manual actuation.

reac es apparent from the foregoing description, With the, transfer table F in place in the exit chamber and with the door D open and thedoor E closed, the forward car (lief the train of cars" is brought into the position shown in Fig. 2 in which it is partly on the transfer tablttF and partly on. the stationary kiln. rails B." The bar K is then manipulatedto bring the hook K back or the lug C of the forward car as shown in Fig. 2. The device L is then operated to retract the bar it and therebv advance the car '6 engaged bpthe hook K until the then front wheels of the car engage the stops F- on the transfer table F. The door-=1) is then closed. The apparatus in this stage is illustrated in Fig. 2.' The door E is next opened and the transfer table F is moved to bring the car. resting" on it into an alinement with the transfer rails I and the car is moved onto the latter. Thereafter the transfer table F is returnedto its position in the exit chal n her. the (1001' E" is closed, and the doorD is opened whereupon the apparatus is in posi-v tion for a repetition of the. operation of advancing and removing from the kiln the to pass under the lug C and its subsequent engagement with the lug G I may employ the automatically adjustable hook M shown in Figs. 4 and. 5. In this construction the op erating bar KA passing through the front wall of the kiln may be regarded as a nonrotatable extension of the bar K of the ap- {paratus shown in Figs. 1, 2 and 3. The hook member M is inthe form of a yoke pivoted to the her KA by the pivot pin M The hook Mis norina 1y gravity held in the position shown in Fig. 4 in which the upper end of its legs ar in position to engage the lug C onthe car 0. It is prevented from turning in the COIIHlJGIrfilOClIWlSB direction from this position by the'stop lugs K carried by the bar KA. "Lie hook M is free to turn in the clockwise direction to permit its upper portions to slide under the car lug G when the bar'KA is moved inward to enas shown, the upper portion of the hook is beveled ed as indicated at M to facilitate tus shown in Figs. 6 and 7 the bar KB is :Mgage a car to be advanced. Advantagously,

mounted wholly within the exit chamber of the kiln and is a rack bar reciprocated by the rotation in opposit directions of the gear wheel P in mesh with the bar and car'- ried by a rotating shaft P The latter pro jects through the side wall of the kiln and is externally gear-connected to a driving motor Q shown as an electrical motor. With this apparatus it is possible to make the operation of the car advancing mechanism purely automatic. For this purpose a switch is shown in Fig. 6 in position to be actuated by th forward car C of the train of cars as which the door I) should be opened. The switch R is connected to the automatic controller S for the motor Q and to start the motor Q in operation when thus actuated a second switch R1 is actuated by a car C moved into the exit chamber when the lat ter comes into the position in which the door D may he closed. The switch R is connected to the motor controller S and serves when actuated to stop the motor Q. In the apparatus shown in Figs. 6 and '7 the kiln AA proper difl'ers from the kiln A pre viously described in having the doors D and. E both transverse to the kiln proper, the stationary track rails B extending from the kiln through the antechamber to the exterior of the latger,

The apparatus shown, in Fig. 8 differs from that shown in Figsffi and 7 in that the shaft P which may be driven as is the shaft P of Figs. 6 and 7, carries a plurality of arms T. These engage the lugs C of successive cars CA. each giving the car engaged by it the necessary advance movement on a quarter rotation of the shaft P The apparatus shown in Fig. 9 dillers from that shown in Figs. 1, 2 and 3 primarily in that'the bar V corresponding generally to the bar K of Figs. 1, 2 and 3 is reciprocated by means of a lever W connected by a link W to a fulcrum block W secured to the end wall of the kiln. The lever W is adapted to engage a collar V carried' by the rod. The latter is formed with a handle V by which the bar may be rotated to bring the hook lugs Vzi'nto, and out of the position in which they-straddl the car lugs C A lug V in position to en age inner end of the stuffing box or bushlng A through which bar V passes and thus limit the outward movement of the bar V and consequently of a car engagedby the latter.

ile in accordance with the provisions of the statutes I have illustrated and described the best forms'of my invention, now known to me, it will be "apparent to those skilled in the art that changes may be made in the .forms of the apparatus disclosed without departing from the spirit of my invention as set forth in the appended claims.-
