IMPROVEMENT IN RESAWlNG-MACHINES.
Specification forming part of Letters Patent No. 165,436, dated Ju y 13, 1875; application filed December 19, 1874.
To all whom it may concern:
Be it known that I, EDWIN BENJAMIN, of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement, in Resawing-Machines, of which the following is a specification:
The nature of the present invention consists in the combination of a friction backgear with the feed-gear and an internal gear, whereby stuff to be resawed may be run rapidly back from the saw in case of accident or otherwise, a lever attachment being used to reverse the feed or take off the feed at will.
In the drawing, Figure l is an elevation of a resawing-machine embodying my invention 5 Fig. 2, a sectional elevation thereof on line :10 m, Fig. 1, looking in the direction indicated by dart 2; Fig. 3, Sheet 2, a top or plan view of the improved machine.
A B represent a substantial frame of suitable form, for supporting the mechanism shown and hereinafter described. 0 D E F is the tilting frame, which supports the feed-rollers G and their attaching-plate H. The means for hanging this frame to the supportingframe A consist of elbows I J, which turn on pivot-bolts K K when operated upon by an adjustingscrew, L, so as to give to the feedrollers G any desired pitch relative to the plane of the saw M.
I do not claim to have invented the tilting frame, but conline myself to the means described and shown for hanging it.
N represents a shaft, which is supported by a box, P, atone end, and by a box, Q, at the other. The box Q is cast solid to or is a part of a plate, R, and supports a bearing, S, for receiving the pivot of a cog-gear, T. The plate R supports bearings U of a cog-gear, WV, aud is arranged, by means of one or more slots and bolts, V, to have a short vertical reciprocating movement for reversing the feed, as hereinafter described. The shaft N supports a friction-pulley, a, and a band drivepulley, O, and the shaft of the cog -gear W supports a friction-pulley, 11, Figs. 1 and 2. 0 represents an external and internal friction- Wheel, which is. hung in bearings e e in the tilting frame O'D E F, and supports a bevelgear, f, meshing into a spur-wheel, g, which, by means of cog-gear h i j, drives the feedrollers G. The shaft of the wheel 9 is supported by a sliding table, k, which is arranged to be moved to or from the saw M, the long.
bevelgear f permitting the spur-wheel g to move some little distance without slipping the gear when in use. On the top of the bed part G is attached a standard, Z, to which is pivoted a lever, m, provided with a connecting plate or rod, n, which is pivoted to the bearing Q of the shaft N, and the lever is provided with an arm, 1, which is weighted to bring the friction-pulley a on the periphery of the wheel 0.
The arrangement of this lever and gearing is such thatwhen the weight 2 controls the lever the pulley a drives the wheel 0 in the proper direction to feed stuff to the saw M, and when the lever m is moved back it operates to bring the friction-pulley 1), Figs. 1 and 2, against the internal periphery of the wheel 0. The feed-rollers G will be turned rapidly back, and carry a board from the saw.
By giving the lever on a medium position the wheel 0 will run without turning either of the pulleys c b. The pulley b, in practice, maybe larger than the pulley a, so that the backward movement of the rollers G may be the quickest.
To bring the feed-rollers G to any desired angle relative to the plane of the saw a collar, 3, is placed on a shaft, 4, which is provided with a spring, 5, placed between the collar and, one of the bearings, 6, of shaft 4., so that the collar may yield and allow the rollers G to permit uneven stuff to be fed to the saw without injury to the machinery. The shaft 4 enters the bearing 6 by means gt a screw-thread, so that by turning the thumbnut or wheel 7 the collar 3, fitting in the bedplate H, will swing the plate on its axis, which is the shaft of spur-wheel g. The saw is driven by means 'of a band on pulley 9, in the ordinary manner, and the wheel 0 is driven by a band running from the wheel 10 on the same shaft as the wheel or pulley 9.
I here state that resawing-muchines are old combination with the friction-rollers a I), wheel and well known; therefore 1 confine myself to 0, pulley O, slotted plate R, and gear 1 9 W f, thepen-ts end'eoinbinationsclaimed. as and for the purpose set forth. 7
I have described mechanism which in some Signed the 15th day of December, 1874. respects is old, better to enable a machine to be built. EDWIN BENJAMIN.
I claim as new and desire to secure by Let- Wiinesses:
ters Patent- JOHN H. ELLIOTT,
The lever m, with its weighted 21-11111, in G. L. OHAPIN.
