METAL PLANING MACHINE.
UNITED STATES PATENT OFFICE.
LUCIUS NV. POND AND FREDERICK E. NORTON, OF WORCESTER, MASSA- CHUSETTS, ASSIGNORS TO HENRY C. FISH, OF SAME PLACE.
METAL-PLANING MACHINE.l
SPCIPICATON forming part of Letters Patent No. 380,692, dated April 10, 1888.
Application filed August 15, 1887. Serial No. 247,605, (No modet) To all whom it may concern,-
Be it known that we, LUCIUS WV. POND and FREDERICK E. NORTON, citizens of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Metal-Planing Machines, of which the followingis a specification, reference being had to Y the accompanying drawings, in which- Figure l represents a side View of a metalplaning machine embodying our invention. Fig. 2 is a rear view of the friction-feeding device, partlyin sectional view. Fig. 3 is a sectional view on line X X, Fig. 2, looking inthe direction ofthe arrow l. Fig. 4 is an enlarged view of one of the driving-dogs, shown partly in section. Fig. 5 is a front view of the device for disengaging the driving-dogs and for applying a friction to the oscillating disk. Fig. 6 :is a side of the same, partly in section; and Fig. 7 shows a modification of the device for applying friction to the oscillating disk.
Similar letters indicate similar parts in the different iigures.
Our invention relates to that portion of a metal-planing machine known as the frictionfeed 5 and it consists in certain improvements in the friction-feed which was made the subject of Letters Patent No. 335,744, granted to Fred F. Dennis, February 9, 1886, as hereinafter described, and set forth in the claims.
By the mechanism forming the subject of the above-named patent, to which reference may be had fora full and detailed description, the motion of one of the reciprocating shafts of the planing-machine is imparted to a disk turning on said shaft, so the reciprocating motion of the shaft, which is varying in its extent and duration according to the movement of the table or platen, is converted into a rotary reciprocating motion of said disk, which is determinate anduniform in extent.
In the accompanying drawings, A denotes the bed of the planing-machine; B, one of the upright sides; and O, a disk having a reciprocating rotary motion by which a feeding motion is given to the cutting-tool through a rod, C', in a manner common to machines of this class.
The disk C is provided with a I"-slot, by which the radial distance of the rod C is varied, thereby varying the amount of the feed of the cutting-tool.
The disk C turns on a shaft, D, Fig. 3, which is journaled transversely to the bed of the Inachine, and which has a rotary motion in op'- posite directions corresponding to the linear reciprocating motion of the table E, which will vary with the length of the work to be planed.
The motion of the shaft D is imparted to the disk O through mechanism described in detail in the Letters Patent to said Dennis, above referred to, and which consists in its main features of a disk, D', attached to the shaft D, and provided with a iiange, D, passing through the openings a a in the dogs D3. The dogs Ds are arranged, as shown in Fig. 2, in a radial position, with their inner ends entering pockets b b in the hub c of the disk C. Each of the dogs D3 is connected bya spiral spring with a stud, di, in the disk C. As the hanged disk D moves in opposite directions, the flange D2 is alternately engaged by first one and then the other of the dogs D3, causing the disk G to be also carried around with the disk D until the dog which is in engagement with the fiange D2 is brought in contact with a pin, F, heldin a plate, F', Fig. 5, attached to the rigid portion of the machine, whereby the pin F is held in the path of the dogs D3 as they are carried around by the flange D2. As the dogs D3 are brought in contact with the stationary pin F, they are disengaged from the flange D2, which then is free to rotate through the opening a in the dog until the reverse movement of the disk D and flange D2, when the opposite dog will engage the ilangc and the reverse motion of the ange be imparted to the disk C until the opposite dog is brought in contact with the stationary pin F, disconnecting the dog from the flange and permitting the continued rotary motion of the flange through the dog. This part of the driving mechanism is substantially the same as that forming the subject of the patent to Dennis, above referred to; but in our present invention We add to the efficiency of the mechanism by adding to the dogs D3 the steel pins d d, which project slightly from the jaws d d of roo the dogs, and which in the patent to Dennis aforesaid were made to engage the iiange directly, and which were liable by continued use to become worn.
By the employment of the pins d d we are able to secure the certain engagement of the flange and also to change them readily when worn. We also cause the inner ends of the dogs to be brought in contact with the pockets at the sides of the dogs, (indicated in Fig. 2 at e 6,) leaving the bottom ofthe pockets free from the dogs. This allows the radial position of the dogs to be determined by the pins d d on the flange D2, which is not the case when the inner ends of the dogs touch the bottom of the pockets. By this means the dogs are rendered self-adjusting, as the pins d d are always held in contact with the flange D2 by the tension of the springs which connect the dogs with the pin or stud d2.
We hold the dogs rmly against the disk C by means of the springsfinserted in a cham ber in the dogs opposite the opening a in the dog. A portion of the flange D2 is broken away in Fig. 2, in order to show the position of the spring in one of the dogs, which is also shown in the sectional view in Fig. 3 and in an enlarged view in Fig. 4. The end of the spring is made to bear directly against the edge of the iiange D2, and thereby press the dogs against the inner surface of the disk C, preventing any lost motion of the dogs in the line of the tension of the springs f. As the dogs are brought in contact with the stationary pin F, the blow is deadened by the strips ot' rawhide or leather g, which we insert in channels running lengthwise of the pin F, allowing the batting-blocks, of leather or similar material, to be drawn out lengthwise the pin and new ones inserted. We also apply a friction to the outer face of the disk C, which is flanged at C2 to increase the friction-surface and also to form an outer shell extending over the inner flange, D?, and prevent the access of dirt or chips from the planing-machine. Our mode of applying this friction to the disk C is shown in Fig. 5, and also what we consider a preferable modication in Fig. 7. A pin, G, projects from the plate F', which is attached to the bed or other rigid portion of the machine, and in a longitudinal groove, h, in the pin G we place a strip of leather, rawhide, or similar friction material, which we bring to bear upon the outer surface of the flange C2 by means of screws h h', Fig. 6. We consider it preferable, however, to omit the groove h and to place a shoe, H, between the pin G and the outer surface ofthe Iiange C2. The shoe H is provided with a recessed surface next the iiange C2 to receive a block of leather or suitable friction material, and the opposite side of the shoe has a concave depression fitting the convex surface of the pin G, a set-screw, h', with a pointed end and countersunk depression in the shoe, allowing a slight rocking motion of the shoe around the pin G in order to secure a uniform pressure over the entire surface of the friction-block in contact with the flange C".
We are well aware that the use of buftingblocks to deaden the noise is well known; also, that the employment of friction devices to moving parts of machines is old, and we do not herein intend to claim such devices broadly; but
What we do claim as our invention, and desire to secure by Letters Patent, is-
l. The combination, with the rotating flange D2 and the rotating hub c, carrying dogs, as described, of the pins d d, placed in said dogs in position to engage the rotating flange, substantially as described.
2. In a friction device consisting of a disk,
C, having a hub, c, a rotating flange and dogs seated in said hub c and arranged to engage said flange, the spring f, in combination with said dogs, substantially as described.
3. In a friction device, the combination, with a rotating disk provided with a flange, a pair of driving-dogs arranged to engage said fiange` and a stoppin held rigidly in the path of said dogs and provided with longitudinal grooves, of the friction-blocks removably held in said grooves, substantially as described.
4. The combination, with a rotating fiange, D2, dogs D3, and disk C, of the plate F', attached to the stationary portion of the machine and having a pin, F, held in the path of the dogs D3, and a pin, G, with connected friction devices, substantially as described.
5. The combination of rotating flange D2, dogs D3, arranged to engage said liange, rotating hub c, provided with pockets b b, holding the inner ends of said dogs, said pockets being deeper than the entering ends of the dogs, so the radial position of the dogs will be determined by the flange Dl, substantially as `described.
