Application nled November 12, 1919. Serial No. 337,602.
To all whom it may concern:
Be it`known that I, ARTHUR C. MoBninn, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Brake- Baud-Relining Machines, of which the following is a specification.
My invention relates to a machine to facilitate the relining of brake bands and the objects of my invention are: First, to prowide a machine of this class whereby the .y brake band lining may be drilled and countersunk while in osition on the brake band; second, to provi e a machine of'this class with power operated means for riveting the rivets in the brake bands; third, to provide a machine of this class in which the drill and countersinking apparatus is combined with the rivetin portion of the applaratus; fourth, to provi e an apparatus of t is class in which the separate o erating parts are contiguous and supporte by means of one supporting member; fifth, vto provide a novelly constructed drill, countersink and supporting pilot for brake bands; sixth, to provide a novelly constructed riveting apparatus and seventh, to provide a machine of thisfclass which is very simple and economical of construction, durable, easy to operate and which will not readily deteriorate or get out of order.
With these and otherobjects in view as will appear hereinaftenmy invention consists of certain novel features of construction, combination andarrangement of parts Aand portions as will Vbe hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which forms a part of this application, in which:
Figure 1 is a side elevational view of the machine and showing portions broken away and in section to facilitate the illustration; Fig. 2 is a top or plan view thereof minus the base and foot levers; Fig. 3 is a fragmentary sectional view through 3 3 of Fig. 1; Fig. 4 is a sectional view through 4 4 of Fig. 1 and Fig. 5 is a sectional view through 5 5 of Fig. 2 on an enlarged scale.
The base member 1 is preferably circular and of a suilicient size to form a base or support for the machine and is provided centrally with an upwardly flanged lug in which is supported the vertical support 2 which is an ordinary pipe of suitable length threaded on both ends and secured on the upper end is a table member 3, annular in form upon which is secured the supporting frame 4 which is preferably a cast iron frame in bifurcated form shaped as shown best in the drawings. Also mounted on this table 3 on the flange 4L of the member 4 is the motor 5. Directly connected to this motor 5 is a main shaft 6 which is journaled in a lug 4b on the side of the frame 4 and extending forwardly to near the extended end of the portion 4c of the member 4. Mounted on the extended end of this shaft 6 is a worm pinion 8 which engages a worm gear member 9 both of which are revolubly mounted in a housing 41 on the extended end of the member 4c and held in adjusted position therein by means of a sleeve 9** screwed into the lower end of the housing 4d and provided with a lock nut 9b for holding it 1n position. The worm gear member 9 is provided with a central hole 9c, the upper end of which is tapered, adapted for the combined drill and countersinking member 10 to be 'wedged therein. Mounted over the upper` end ot the housing 41 is a curved surface gauge member 11 which is supported by means of springs 11", the lower ends of which rest in recesses in the housing 4. This member 11 is provided with a central hole 11b adapted to permit the upper end of the member 10 to protrude therethrough when the sprin 11l are compressed. n the one side of e housing 4 is an adjusting screw 11, shown in Fig. 1 of the drawings. This adi'usting screw is mounted in a threaded ho e in the housing 4d and 1s provided with a hole adapted to receive .a pin 11*1 mounted on the member 11. This adjusting screw 11 is ada ted for a stop for the member V11 in its ownward moveme'nt and is adapted to re ulate the depth of the countersink in the rake lining by regulating the de ressiou of the gauge member 11. Mounte immediately over the center of the member 11 and reciprocally mounted in the head 4 is a presser foot member support 13 which is actuated by means of the lever 14 pivoted on a bolt 14, said member 13 being connected by means of a pin 13n on the outwardly extended end of which is a roller 13b whichis mounted in a slot in the end of the lever' 14. The opposite end of the lever 14 is connected with the rod 15 which extends downwardly and is secured to one end of the foot lever 16 which is pivotally mounted on a shaft 1* on the base 1. Mounted on the rod 15 is a compression spring 15 tending to hold the rod 15 downwardly which in turn holds the member 13 up in the position shown best in Figs. 1 and 4 of the drawings. Secured tothe presser foot member support 13 by means of threads 12 is the resser foot member 12 which is provide with. a hole in which is mounted a compression spring 12b, the one end of which sets against a pilot 12, the other end is adapted to protrude from the lower end of the member 12. The end of this pilot 12 is yadapted to be inserted in the hole in the brake band with the lining in position, when the lever 16 moved until the brake lining contacts with the member 11 depressing the same until the member 11 engages the adjusting screw 11 thus drilling and countersinking a hole in the brake lining, the drill and countersink 10 heilig revolved by means of the worm ear member 9 through the pinion 8 and s aft 6 op erated by the motor 5. Adjustably mounted on the member 4 in the portion 4 is an anvil 7 which is threaded on its outer surface and adapted to screw into an enlarged portion 4' of the member 4. This anvil member is provided with a lock nut 7a adapted to set up against the lower surface of the enlarged portion 4' and hold the anvil meniber 7 in adjusted osition. The upper end of this anvil mem er 7 is provided with a lug portion 7" adapted for the rivet to rest upon. Reciprocally mounted directly over this lug 7 is a riveting plunger 17 provided with a reduced portion with a cup shaped end 17a adapted for a head For the rivet on the opposite side of the brake band from the lining. This plunger member 17 is recipnavales rocally mounted in a cylinder 18 fitted into an eniar d portion 4 of the bracket 4. This cylinder 18 is provided with several diameter chambers andthe longer 17 is also provided with several iameber portions. The c yiinder 18 is provided with ports 18 Whlch extend downwardiy and communicate with the lower end of one of the intermediate chambers in the cylinder 18. The plunger 17 is provided with a plurality of exhaust ports 17c which communi.- cate with a large port 17 d, which extend upwardly through the center of the plunger 17 to the upper end to permit air to pass from above the u per end of the plunger 17 and out throng the ports 17e to the outside when the plunger 17 is in certain relative position to the cylinder 18 which would be the down stroke of said plunger. The plunger 17 is actuated upwardly by the air pressure against the enlar ed portion 17 of the plunger 17 until the p unger raises to a position so that the groove 17f communicates with the enlarged portion 18 of the cylindcr 18 when it passes throuvh the ports 17s and around the upperI end thereof to above the same causing the plunger to descend thus providing a rapid reciprocating action of the plunger 17 for riveting purposes. Communicating with the ports 18* in the cylinder 18 is an air conductor 19 which communicates with a chamber 21a to which is secured another chamber 2lb and adapted to seat on the lower end of the chamber 21h is a valve 21 which is actuated by the valve rod 22 which extends downwardly and its lower end is pivotally connected with a foot lever 23 pivotally mounted on the shaft 1 on the base member 1. Mounted on the rod 22 is a compression spring 22L tending to hold said rod 22 downwardly so that the valve 21 is seated. However, upon the depression of the foot portion of the lever 23 the valv(` 21 will be raised to the position shown h v solid lines in Fig. 1 of the drawings` whereupon the air from a compressed air reservoir will pass through the conduri'or 20 inlo :l chamber 2lh and through the valve 31. through the conductor 19 and into the ports 18 for operating the riveting plunger 17 and that when the level' 23 is released ille-spring 22 will close the valve 2l, the air pressure is relieved and the plunger 17 will stop.
Though I have shown and described a. particular construction, combination and arraugment of parts and portions I do not wish to be limited to lthis particular construction, combination and arrangement but drsire to include in the purview oi my invention the construction, combination and arrangement substantially as set forth in the appended claims.
lt is obvioi'ls that with this construction there is provided a machine for relining lim llu
brake bands which consists of means for drilling and countersinking the brake lining when in position on the brake band and guided by a pilot member engaging the hole in the brake band; that the epth of the countersinking inthe brake Alining is adjusted by means of the adjustin screw 11 which controls the movement o the member 11; that the rivets are riveted by means of the plunger 17 in the one end of the rivet, supported by means of the anvil 7' adjustably mounted in the portion 4 of the bracket 4 and both operations are regulated and controlled by the foot levers 16and 23, while the operators hands are free to hold the brake band and lining in position.
