METAL-BREAKIN G DEVICE.

Application filed August 15, 1924. Serial No. 732,335.

operation.

Another object of the invention is the provision of a new and improved shield or mantle mechanism for a wheel breaking device and means for automatically raising and lowering the same during the breaking operation. 1

1V hile the device is adapted to break into smaller pieces metallic articles of various kinds, it is especially adapted to break discarded car wheels and the like into smaller particles in order to facilitate the melting of the same. For simplicity of illustration and convenience of description a car wheel breaking device has been selected. to disclose one embodiment of the invention.

()n the drawing, the reference character 10 designates an anvil on which the car wheel or other metallic article 11 is adapted to be placed preparatory to breaking the same.

The anvil 10 is supported in any convenient manner, as by means of the base 12.

The wheel. is adapted to be broken by a falling weight 13 which is elevated androleased in pile driving machinery. As shown, a suitable tower comprising the up rights 1 1 and bracing members 15 is mounted over the anvil and forms a support for the vertically extending guides or leaders 16 and 17 which may be in the form of I-beams spaced apart as shown in Fig. l, and which constitute a gnideway for the hammer or weight 13. The guides 16 and 17 are connected together by the members 18 and are braced from the tower by

suitable braces

19 and 20. In order that the hammer or weight may be readily removed torreplacen'lent or repairs or for removing small particles 01 the broken metal that may be projected up wardly and become wedged between the guides and the hammer or weight, one of the guides or leaders as 16 is pivoted at its upper end as at 21 whereby the same may be swung outwardly and the piece of broken metal, or the weight, removed when desired.

Suitable. means are provided for raising the weight or hammer 13 and for automatically releasing the same when it reaches a undetermined height. As shown, the weight is reduced at its upper end. to form a head 22 having oppositely arranged shoulders 23. thereon. The shoulders may be formed by steel inserts asshown in Fig. 5. The shoulders 23 are adapted to be detaclt ably engaged by a pair of weight ei'igaging members or tongs 2 1 pivoted to the tong housing 25 slidably mounted in the guideway formed by the leaders 16 and 17. The housing 25is raised by means of a cable 26 which is connected to said housing and is trained over suitable sheaves or pulleys 27 on the top of the tower under a pulley 28 at the base of the tower and over a pulley 31 mounted on the piston 32 of the hydraulic lifting motor The lower end oil" the cable 26 is secured by any suitable means at the base'ot tl'ie-motor 33. The motor 38 is controlled by a valve operating lever 30 in the usual or any well known manner, the water entering through the pipe 380 and being discharged through the pipe 39 as is usual in such constructions.

The tongs 24 are so constructed that when the housing 25 is lowered they will auto matically engage the shoulders 23 as is usual in such constructions. The tongs are providedwith the extensions bent to form inclined surfaces for

engaging release blocks

36 and 37 at the upper end of the guideway for automatically releasing the weight 13 and permitting the same to fall by gravity on to the anvil 10 for breaking metallic articles placed thereon.

In breaking metallic articles in this manner, broken particles are likely to be projected in all directions,and in order to prevent injury to persons or property, means are provided for surrounding the article on theanvil during the descent of the weight.

In the form of the device selected to illustrate one embodiment of the invention, a shroud or shield 38 is employed'for this purpose. The shroud is provided at its lower end with an enlarged recess 39 which is adapted to extend over and about articles placed on the anvil, and its upper end is provided with a guide 41 which is adapted to conform to the contour of the outer surface of the guideway formed by the leaders 16 and 17, as clearly shown in Fig. 4 of the drawing. The shroud is adapted to engage the anvil 10and form a housing or shield for the Wheel 11 or other metallic article during the breaking operation.

Suitable means are provided for automatically'elevating the shield for permitting removal of the broken article and the insertion of a new one. Any suitable means may be employed for this purpose. As shown, the

guides 41 of the shield are provided at oppo site sides thereof with dogs or

latches

42 and 43 which are adapted to engage

shoulders

44 and 45 secured to the weight 13. The

latches

42 and 43 are provided with weights 46 which are adapted to hold the said latches in retracted position. Suitable stops 46 limit the downward -movement of the Weights 46. A lever 47 is provided at each side of the leaders for engaging the

latches

42 and 43,. These levers are pivoted to brackets 48 extendingin opposite direction from the said leaders. Each lever is provided With an arm 49 for engaging the cor responding latch and with an upwardly extendmg arm'51' for engaging cam surface 52 provided on each side of the tong housing 25. The arms 51 may be provided with suitable anti-friction rollers for engaging said cams. In the operation of the device, the shield is lowered in position over the article to be broken and the weight is re leased, which will break the article into fragments. The tong block 25 is now lowered, and the tongs will automatically engage the shoulders 23 for raising the weight. In the meantime the arms 51 will engage the cam surfaces 52 as the block 25 descends thereby moving the

latches

42 and 43 inwardly to engage the

shoulders

44 and 45.

broken wheel off of the same.

The tong block 25 is now elevated, carrying with it the weight 13 and the shield or shroud 38. The shield or shroud 38 continues to be elevated until the inclinedsurfaces 53 of the

latches

42 and 43 engage the cams 54 secured to the runners (3 and 17. lefore the latch members come in contact with the cams 54 the cam surfaces 52 will have passed upwardly beyond the arms 51, therebypermitting the latches 42 and -13 to move outwardly when they engage the cane; 54, to thereby release the shield and to permit the same to drop back on the anvil It).

Suitable means are provided for recharging or for moving metallic articles on to the anvil and for removing the same after thev have been broken. Any suitable means may be employed for this purpose. As shown. a. hydraulic motor 55 is employed. The motor may be of the usual or any weltknown construction and comprises the stationary pis ton GO and the movable cylinder 57 to which is attached the plunger 58, operating in the guideway 59. The cylinder 57 is retracted by means of a weight 61 connected thereto by a cable 62 extending over a pulley (33. The weight (31 is adapted to be raised and lowered in the well 64 provided for that. purpose. The motor is controlled by the operator by meansof the lever 56 (see Fig. 4), in the usual manner. lVhere the device is employed for breaking car wheels as in the form of the apparatus illustrated, the front end. of the plunger 58 is curved as at 61 to conform to the curvature of the wheel.

In the operation of the device, after a wheel has been broken by the descent of: the weight 13 and the wheel has been placed in the guide 59 in front of the plunger 58, the operator moves the valve 33 to raise the weight and shroud above the wheel and anvil. The upward movement of these memhers is stopped when the same is above the wheel 11 and the valve lever 56 is operated to cause the plunger 58 to advance, moving the wheel (34 on to the anvil and forcing the After the plunger 58 has returned, the block 25 is again moved upwardly, which causes the latches 53 to engage the cams 54 to release the shroud, which will thereby descend on theanvil over and about the wheel 11. The parts are now in position for the descent of the weight 13, which occurs when the extensions 35 engage the cams 3G and 37.

It is thought from the foregoing taken in connection with the accompanying drawings that the construction and operation of my device will be apparent to those skilled in the art. Various changes in size, shape. proportion and details of construction may be made without departing from the spirit and scope of the appended claims.
