This invention relates to a stereotype plant or machine in which stereotype plates "are cast in two or moreboXes 'or molds and finished in a single finishing machine which moves totake care of the products of all the casting machines. i i

The principal objectof the invention isto provide an automatic traversing device for a finishing machine in which the machine will move from one position to another in a time p less than that required to finish; the plates, so that it will be in its delivering position before the finishing operation isgcompleted and the operator can be there ready to assist in the discharge of the plate and will not have to be there merely at the" time the machine stops moving laterally; also to'provide means connected with the shaving shaft for traversing the shaving machine, and means for throwing the traversing means out ofgear automatioally at the desired times to secureithe above mentioned result; and, to provide means whereby the machine can be started conveniently from either side by hand and will then stop automatically at the other side with the shaving shaft still running. 7 Otherobjects and advantages of the inventionwill appear hereinafter.

Reference is to be hadto the accompanying drawings in'which Fig 1 is a plan of a casting and finishing plant of the twin type showing a'preferredj means of applying this invention thereto, the finishing machine itself being indicated only in dotted lines to show one of its, positions; p r

I have not illustrated or described anypar tioular form of casting box as this machine is intende'dito be used withgany ordinary kind, but I have indicated a well known formfor convenience. i a f The two casting machine frames are mounted in fixed position as shown here, with their central lines converging to a point, about which point ;the finishin machine swings to receivethe products rom them alternatelyfand finish them. lnaccordance with the present invention, thewhole machine is run from one motor, but the traversing operation is completed before the finishing operation The finishingmachine, therefore, comes to rest in line with the empty casting boxwhilethe shaving shaft and trimmers are still operating. This permits the operatoiy'before the finishing operation has been completed, to go from the point at which he starts the machine to the far end of the machine and be ready to remove the plate. a

The. finishing machine comprises a frame 10 mounted on avertical shaft or stud 16 about which it can swing. It has a concen- 'tric track 17 on which a pair of rollers 18.0n

WOOD NEWSPAPER MA- 1 tary trimming saw or saws 22. The saws are rotatable bodily about the shaving shaft 21 of the finishing apparatus. On the end of the shavingfshaft is a worm gear 23, which is driven vby suitable gearing from a shaft 24. To this shaft is fixed one of the train of gears from'themotortothe planetary saw. The shaft 24 has a pinion 25 on the end which drives a spur gear on which isfixed a bevel gear 26. Thisbevel gear meshes'with two op! posite bevel gears 27' either one of which can be. connected by a sliding clutch 28 with .a vertical shaft 29 on which they are freely machine but on the same shaft.

mounted. This shaft 29 is mounted in brackets 30 on the finishing machine, and is pro vided with a pinion 31 at the bottom meshing with the rack 19. It will be obvious that the frame 10 will swing about the center 16 in accordance with the direction of rotation of the shaft 29 as controlled by the clutch.

This clutch is controlled by a clutch lever 33, which can be operated from either side by handles 34. Each handle is on a vertical rock shaft 35. This shaft has arms 36 operating a shifter 37 on a horizontal rod 38 connected with the ends of the two sets of arms 36 at the opposite sides of the machine. The operation of either of these handles 34 will swing the clutch lever 33 on its pivot 39 and throw the clutch one way or the other.

The clutch lever is provided with a toe 40 adapted to engage one of a pair of fixed stops 41 at the ends of its traverse, these stops being located on the track. This constitutes the clutch operating mechanism.

The clutch mechanism is interlocked with a pair of handles 43 on the two sides of the They have projections 44 adapted to engage projections 45 mounted on the arms 36 or otherwise c011- nected with the clutch operating mechanism. These are arranged so that the clutch cannot be engaged when the handles 43 are in the position shown in Fig. 4; They have to be raised to allow the clutch to be brought out of neutral position.

The starting of the motor is accomplished through aswitch 46 which is operated from the bell crank operating lever 33 through a connection 47 thereon. The stopping of the motor at the end of the finishing operation is accomplished by a similar switch 48 operated by a pin 49 on the worm wheel 23 of the shaving shaft.

In Fig. 6, I have shown the rack as consisting of a chain 50 stretched taut on a curved surface 51 and engaged by a sprocket wheel 52 which I regard as the equivalent of the rack and pinion shown in the other figures.

In the operation of the device, assuming the parts to be in the position shown in Fig. l, with the left-hand box just having delivered its casting to the finishing machine, the two handles 43 are lifted by the operator stationed at the left to avoid interference of the

projections

44 and 45. Then the handle 34, which is on the outer side convenient to the operator, is turned to throw the clutch in. and close the starting switch 46. This, of course, starts the motor 20 with the clutch in so that the first. part of the operation will turn the shaving shaft and the tail cutter, and also at the same time swing the frame 10 about its pivot clue to the rolling of the pinion 31 along the rack 19. .Now when the shaving device has turned to a position in alignment with the other casting box, the

stop 41 at that time will be engaged by the toe 40 and will automatically turn the clutch to neutral position. The shaft 21 will continue to operate to complete the finishing operation, however. The attendant has time to get over into the proper position to take out the plate or receive it and place it in the cooling saddle 53 or remove it from the ma chine. Then he goes to the opposite side of the machine to start it again in the same way. It will be understood, of course, that during this period the plates are being cast and cooled in the other box ready to be delivered to the machine before it starts back. After the finishing machine stops in its second position, the levers 43 are turned down so that the machine cannot be started accidentally or by any one merely turning one of the handles 34.

This invention cconomizes in the first cost of a plant because one finishing machine can take care of the product of two casting boxes on account of the delay necessitated by the cooling of the plates. It provides automatic and efiicient means for traversing the finishing mechanism in such a way that it will come to rest as a whole before the finishing or shaving shaft has completed its entire operation, thus furnishing the advantages above mentioned.

Although I have illustrated and described only one form of the invention I am aware of the fact that changes can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.
