Patented New, 191?? means for actuating the bottle distributing mechanism. a 1

Fig. 5 is a sectional view taken on the line 55 of Fig. 3.

Referring now more particularly to the accompanying drawings, 5 designates each of the side walls of an elongated annealin oven 6 designates the bottom Wallthereo and designates the top wall thereof which terminates short of the side walls ,at the receiving end of the oven, the space between the end of the topwall and the ends ofthe side walls being closed by a journal plate 8 for the bottle distributing mechanism.

The. bottom 6 of the oven carries a longitudinal pair of tracks 9 for the wheels 10016 aseries of'bed trays and each of these-bed trays comprises apair of longitudinalw-heel carrying sills 11 and a plurality of ,transverse floor plates 12 preferably formed, of

sheet iron and having their edgeportions bent downwardly, aS shoWn- -more: particularly at 13 in Fig. 1 to-seat into notchesyoi the sills 11 whereby to'stifi'en said plates".

The detachable connection of the trays is procured by lugs 14: on the rear endsfiof. the side sills engageable in sockets 15 of-the forward ends of said sills, and thus aslthe bed trays are moved through the oven, the

endmost trays may be readily connected and disconnected to afi'ord a'continuous movable bed inthe oven. For procuring movement through the oven of the series of trays thus connected, each tray is provided with arentral longitudinal toothed-rack 16 'andythese racks are successively eng'age'able' with a gear 17 carried by a shaft 18 journaledij' in the bottom 6 of the furnace andin a bracket carried by a transverse beam ,l9' zthereheloyv.

The racks areheld inmeshGWith the gear by an idle pulley 20 mounted 0n=the bottom 6 at the opposite sides of the racks;

,For feeding and distributing bottle 'e oven, a chute 21 is provided at one ide'bf the feeding end of the oven and thischutemay be fed in any manner. procurifigia' ositive movement of bottles -tliereoI -a suite is: con

veyer, (notl shown') being preferablyiipr w Vided to copve. 7 bottles tofithe (grate-r seedy on th plate 8. an in thel racket of a t beamflfl sm d bathe. w sidej fwalls verticaljshaftgg nat'es iintrie'diaftely rabovevth pv th wh h e iess a 1 swear p jfovided with oil 1 eda'in discharged from the cylinder after each actuation of the ripheral fingers having their ends laterally curved in the direction of rotative movement of the wheel and defining a peripheral series of consequent pockets adapted to successively receive bottles as they are forced from the chute 21, which asshown is provided with upstanding guide walls at its sides. For

procuring successive rotative'step movements Iof this wheel as bottles are supplied thereto,

a wheel 25 is fixed on the shaft 23 above the top plate 8 and carries a double series of ratchet teeth, one series being engageable by a feed awl 26"carried by a lever 27 intermediate y pivoted on the shaft and having its other end in link connection with the stem 28 of a piston 29'disposed in a cylinder 30 from which apipe 31 extends to a valve 32 "disposed adjacent the discharge end of the chute, this valve being connected in turn by the pi e 33 with a suitable source of compressed air. The valve is operated by a spring urged roller carrying stem 34 rojecting therefrom into the path ofthe ot- .tles as they are discharged from the chute and thus as ,the bottles successively move from the chute, the valve will be 0 ened to impart successive rotative steps to t e wheel carryingshaft through the medium of the cylinder andpiston and the pawl 26. For stopping the shaft subsequent to each rotative impulse, an arcuate pawl 35 is pivoted on the plate Sand is resiliently urged to en- I gagement with the other ratchet teeth of the wheel 25 by a spring urged link. 36 connected therewith. The lever 27 carrying the pawl 26 is resiliently urged to initial position by a spring 37 on the piston stem 28, and air is piston by any suitable means and preferab y by providing the valve 32 of a two-way type normally open with respect to 'the cylinder, the structure of this valve being not shown, as any preferably conventional valve may be used.

Thus upon a plurality of bottles being fed into'the oven, they will be disposed along the inner side of the periphery of the wheel, as shown moreparticularly m Fig. 3. To

' clear the .bottles fromthe wheel when an inder 42 from whence a pipe 43 extends to a arcuate series thereof has been fed into the oven, an arcuate sweep 38 is provided which normally extends transversely over the wheel, and which is carried by a vertical shaft 39 at theside of the wheel opposite the chute 21, thisfshaft being journal'ed in the top plate 8 and in the transverse beam 22. For actuating the shaft to cause an inward sweeping movement of the sweep 38 a crank-arm 40 is provided at its upper end which is in link connection with the piston stem 41 of a cylvalve44 connected also with a suitable source of air pressure 45, this'valve being operable by a roller carrying spring urged stem 46 which projects into the rotative path of the bottles carried by the wheel 24, and thus upon engagement of the bottles therewith procures t e swinging movement of the sweep to clear the bottles from the wheel and dispose them in a substantially angular line on the movable bed, it being noted that the action of the '-s eep is comparatively rapid inasmuch as it must return to initial position prior to the engagement of subsequent bottles with the wheel. In view of the very slow feeding movement of the bed of the oven, the successive rotative movementsof the wheel serve to retain the bottles in the pockets thereof, particularl by reason ofthe forward inclination of the wheel fingers with respect to their direction of travel. For

returning the' sweep in a rapid manner, a

relativsly strong spring 47 is connected with the era -'arm 40 thereof.

For closing the receiving end of the oven, a hood 48 is hinged to one side wall thereof above the movable bed trays and this hood comprises an arcuate vertical wall providing clearance for the wheel.

As-the bottles arefed into the oven from the molding machine they are at a considerable heat, and to provide for a proper heating of the bedtraysprior to engagement of the bottles thereon, a compartment is formed in the forward end of the furnace by the rovision of a partition wall 49 below the ottom 6 of the oven and disposed in this compartment are supply coils 50 which may form part of any heating means, the bottom 6 of the oven immediately'above the compartment being provided with series of apertures, and it is noted that the heatin of the bed travs is facilitated by reason 0 the relatively thin metallic floor plates thereof. The rotation of the shaft 18 which carries the gear wheel 17 for procuring feeding movement of these bed trays is procured through the medium of a worm gear connection 52 with a countershaft 53 rojectin outwardly of one of the side wafils 5 an driven in any suitable manner.

While I have shown and described a ferred embodiment 'of my invention, 1t is obvious that to meetidifiering conditions of use, various changes and modifications of structure may be resorted to without de arting in any'manner from the spirit 0 my invention.

I claim:
