WHEEL-BREAKING MACHINE.

Application filed September 8, 1922'. Serial No. 586,962.

T 0 all whom it may concern:

Be it known that we, FREDERICK R. LONG and JAM s A. HARRY, residing at Berwick, in the county ofColumbia and State of Pennsylvania, and being citizens of the United States, have invented certain new and useful Improvements in a \Vheel- Breaking Machine, of which the following is a full, clear, and exact description, such as will enable others skilled in the artto which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Fig. 1 is a side elevation, with part shown in section and part broken away, of our improved wheel breaking machine;

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 3, the base being shown in elevation;

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1;

Fig. i is a detail view, partly in elevation and partly in section, showing the means for automatically releasing the drop weight; and

Fig. 5 is a view in elevation of the cam wheel which controls the operation of our device.

It is an object of our invention to provide an improved machine for breaking car wheels and it is also an object of our inven tion to provide a machine in which the action proceeds automatically after a wheel is placed upona platform adjacent the anvil of the machine. It is also an object of our invention to provide a machine of the type described which shall be continuously operated and in which the various operations shall follow in predetermined sequence at predetermined intervals.

ith these and other objects in View, our invention comprises a substantially rectangular base 1 of concrete or other suitable material upon which is supported an anvil 2 substantially rectangular in shape and having a rounded portion 3 provided with a series of projections at adapted to engage in depressions 5 in the base. Upon opposite sides of the anvil 2 are placed uprights 6 and 7, joined together at their tops by a cross piece 8 and which carry guides 9 upon which a drop weight 10 is adapted to travel. To one side of the anvil are pivotally secured the connected arms 11 having a wheeled axle 12 at their outer ends adapted to travel upon tracks 13 carried upon uprights 14; mounted upon base 1. Mounted upon the arms 11 is a platform 15 upon which a wheel 16 is placed by a crane or other suitable device (not shown). To the other side of the anvil 2 there is pivotally secured a chute 17 which at its lower end rests upon a projecting supporting and guiding member 18 carried by the base 1. The anvil 2 is adapted to be tilted about the rounded portion 3, the projections 1 engaging the depressions 5 and serving to guide the anvil 2 upon the base 1 in its tilting movement and to insure its return to the proper normal position. To operate the anvil-2 there is provided a main drive shaft 19 mounted in bearings in pedestals 20-and having a pulley 21 to which power is supplied from any suitable source (not shown). Loosely mounted upon the shaft 19 is a combined gear, and clutch member 22 comprising a gear 23 and clutch portion 2%. The gear 23 is adapted to mesh with a gear 25 mounted upon one end of a shaft 26 carried in bearings on pedestal 2?. Upon the other end of the shaft 26 is a crank disk 28 and on the crank disk 28 and gear 25 are studs 29 to which are pivotally connected rods 30 which serve to connect the gear 25 and crank disk 28 to the anvil 2 the rods 30 being pivotally connected to the anvil 2 also. Splined upon the shaft 19 is a clutch member 31 adapted to cooperate with the clutch member 24 and operated by a yoke 32which is pivotally mounted in a bracket 33 carried by the base 1. of the yoke 32 is secured a rod 3 1 slidably mounted in guide brackets 35 and having at its other end a roller adapted to be engaged by a cam 37 on the toothed cam wheel 38. The cam wheel 38 is rotatably mounted upon the shaft 19 and is provided with gear teeth which mesh with a gear 39 To the lower end Cir til)

carried by a shaft 19 mounted in bearings in pedestals 41 carried by the base 1. The shaft a is driven by a gear 12 which is in engagement with a gear sit mounted on the shaft The gears 13. 42. 39 and cam wheel 38 .t'orm a reduction gearing which serves to drive the cam wheel 38 at a predetermined speed less than the speed of the shaft 19. Engagement of the cam 37 with the roller so will cause the bar 3t to be shifted, operating the yoke 3.2 to engage clutch member 81 with the clutch member 2. L- causing rotation of the gear 23 and gear and crank disk thereby causing the tilting of the'anvil 2. The length 01" the cam 37 is sullicient to hold the clutch members 31 and 2% in engagement long enough to cause a complete rotation of the gear 25 thus causing the anvil 2 to be tilted to it extreme position and returned to its normal position which the cam 37 will be moved past the roller 36 and permit the clutch members 31 and 21 to be disengaged by the action of the spring llwhich surrounds the bar 31 and which is confined between a guide bracket 35 and a fixed stop a on the bar 3%.

The drop weight is provided at its upper end with an eye to which is adapted to be engaged l a hook 17 pivotally mounted in a counterbalance weight -18. The counterbalance weight 48 is provided with an eye 49 to which is secured a cable 50 which paszes over a pulley 51 mounted in a bracket 52 secured upon the cross member 8. The other end of the cable 50 is wrapped about a drum 50 which is rotatably mounted on the shaft 19 and is provided with a clutch portion 54. The clutch portion 5% is adapted to be engaged by a cooperating clutch member 55 splined upon the shaft 19 and operated by a yoke 56 which is pivotally mounted at its other end upon a bracket 57 carried by the base 1. Secured to the yoke 56 is a bracket 58 in which is mounted a roller 59 adapted to be engaged by a cam lit) carried by the cam wheel 38. Engagement of the roller 59 by the cam will cause the engagement of the clutch members 55 and 54. causing the drum 50 to be operated by the shaft 19 and the cable 50 to be wound about the drum 53 raising the drop weight 10 in its guides 9. The cam 60 is of sutlicient length to hold the clutch members 51 and 55 in engagement until the drop weight 10 is raised t'ar enough to cause the projecting end (51 of the hook 17 to be engaged by the weighted end 62 of an arm 64 which is pivotally mounted on the side member (3. Engagement of the weighted end 62 with the hook l? will cause the hook to be rotated about its support and disconnected from the eye d6 of the drop weight 10 permitting the drop weight 10 to fall. The arm 6% is normally held in a position in which it will engage with the hook 17 by an extension of one of the guides 9. To insure. that the weighted end (32 will operate the hook =17 there is provided a stop (it; secured to the cross piece 8 whicn will engage the weighted end 62 when the ct nterbalance weight -18 is at the upper limit ot travel. The cam (30 will be clirsengaii'crl from the roller 59 as the Cotill'r'tflljzllilllee weigh" reaches its upper limit of travel whrreupoi spring 61' will operate the yoke in; to dis engage the clutch n'icinbers in and i5 pcrinitting the coiuuerhalance we ght 1* to E l unwinding the cable from the drum and bringing the book 17 into eng enieni with the eye 16 in the drop weight i l.

The cams 37 and (it) are so positioned on the cam wheel 38 and with respect to tilt rollers 36 and .39 that, in operation. the clutch members and 551 will be eng M d slightly in advance oi. the e 'cment oi the clutch membe s 91 and ..i that the drop weight 10 will be raised irom the anvIl 2 a short distance betore the tilting ot' the anvil 2 is started. As the anvil 2 tilted from the position shown in full lines in Fig. 1 to the position shown in dotted lines in the same figure by the operation of the crank disk 28 and gear 25. the arms 11 are raised. as the corner of the anvil to which llaends of the arms are connected rai d and at the same time they are moved lo;-

ward the rollers 12 traveling on the tracks 13 so that a wheel 16 placed upon the platform 15 will be brought into engagement with the inclined surface t; oi a shield to which is slidably mounted in guide TH carried by the side members (3 and T. The wheel 16 is prevented from sliding on platform 15 by stops T2 so that as the plat'lorni and wheel are moved forward the shield (19 is raised and the wheel pas. l

The wheel which had een previously placed upon the anvil 2' and which had been broken by the (hopping oi" the drop weight 10 is discharged troni the anvil 2 down the chute 17 by the lihing oi the anvil 2. the anvil in its tilting movement raising a guard Tl pivolally re cured to the uprights (i and T. is: the anvil 2 is returned to its normal position. iiic arms 11 will travel along the rails 1 bringing the wheel 16 into engagement with the shield (55) and causing the wheel in to inslid along the platform 17 and on to the anvil 2. the wheel as being held in a position between the uprightmembers (3 and T so that upon the return ot the anvil 2 to its normal position, the wheel in will have been shifted from its position on the plattorm 15 to a position on the anvil 2 beneath the drop weight 10. Upon the return of the anvil 2 to its normal position the clutch members 31 and 24 are disengaged by the movement of the cam 37 beyond the roller 36. Thedrop weight 10 is meanwhile being raised to a position in which the hook 47 will be disengaged from the eye so as to release the drop weight 10 to fall upon the wheel 16 which has been placed upon the anvil 2. Upon release'of the drop weight 10 the cam member 60 moves beyond the roller 59 permitting the spring 67 to disengage clutch members and 54: and allowing the counterbalance weight 18 to bring the hook 47 into engagement with the eye 46 in the drop weight 10. Meanwhile another wheel has been placed upon the platform 15 and engaged with the stops 72 so that upon the engagement of the cams and 37 with the rollers 59 and 36, the device is ready to repeat the operation. It will be noted that in the operation of our device it is only necessary to place the wheels to be broken upon the platform 15, all the other operations of the device taking place automatically in the proper sequence at predetermined intervals so long as power is applied to the drive shaft 19.
