Opinion

GROSSCUP, District Judge.

The bill is to restrain infringement of letters patent No. 879,550, granted to complainant, on application of S. P. Welch, March 13, 1888, and also to restrain infringement of letters patent No. 380,068, granted to complainant, on application of S. P. Welch, March 27, 1888. Both of these patents relate to road scrapers. Patent No. 379, 550, with the claim relied upon, is as follows:

To All Whom It .may Concern.: Be it known that I, S. Frank Welch, residing at Mt. Pleasant, in the county of Henry and state of Iowa, and a citizen of the United States, have invented a new and useful improvement in road graders, of which the following is a specification, reference being had to the accompanying drawings, in which Fig. 1 is a plan. Fig. 2 is a rear elevation. Fig. 3 is a side elevation. Fig. 4 is a detail, being a longitudinal section through the rings, F, 6, and pinion, e. Fig. 5 is a detail, being a section at line, x, of Fig. 1. My invention relates to that class of road graders in which the scraper is supported by a frame mounted on wheels, and in which it can be adjusted vertically and laterally, and can be set at different angles of diagonal adjustment to the roadbed. The leading object of my invention is to provide convenient and efficient means, by the use of which the various adjustments desired can be secured, which I accomplish as illustrated in the drawings, and as hereinafter fully described. Those things which I claim as new will be set forth in the claims. In the drawings, A, A', represent the front and rear wheels of the road grader, which wheels are supported on axles as usual. B, B', are the front and rear bolsters. The front [195]*195holster is pivoted on the front axle, and the rear holster is rigidly attached to the rear axle. G is a frame suported by the holsters. D is a draft hook which passes through the front axle, and is pivotally secured thereto by a king holt, a is a loop which passes through the forward end of the draft hook, D, the forward end of the loop being connected with the tongue, b is an upward projection from the rear end of the draft-hook, D. E, E', are two bars of a bifurcated beam having an eye at its front end, which is loosely attached to the projection, h, upon the draft-hook, D. F is a flat metal ring rigidly secured to the under side of the bars, E, E'. This flat ring has a flange, e, at its lower inside edge. G is another flat ring, which has a flange, d, at its outside upper edge, which flange, d, rests loosely on the flange, c, of the ring, F, and this ring, G, can rotate freely within the ring, F, and it is held in place by the bars, E, E', beneath which it is located. H, H', are arms, the inner ends of which are rigidly secured, respectively, to the bars, E, E', and they are also secured to the plate, F, and being located above the ring, G, they aid in holding it in place. T, I, are two curved arms, the upper ends of which are rigidly secured to the flat ring, G. ,T is a transversely curved scraper blade, which is rigidly secured to the free ends of the curved arms, I. K is a toothed rack, which is rigidly secured to the lower side of the flat ring, G, and the rack extends nearly one-half the circumference of the ring. The rack may be made integral with the ring, G, or it may he bolted or riveted thereto, e is a pinion at the rear of the flat ring, F, and journaled thereto, which pinion engages with the rack, K. f is a shaft upon which the pinion, e, is secured, and g is a. hand wheel at the upper end of the shaft, f. h is a pin arranged to engage with and lock the pinion, e, in any desired position; the pin, h, being operated by the hand lever, i. j, j, are chains attached at one end to the rear ends of the bars, E, E', or to the ring, F, which chains cross each other, and, after passing around the sheaves, k, k, are attacked to the opposite ends of a spiral-grooved spool or drum, 1. This drum, 1, is journaled to a crosspiece, m, which forms a part of the main frame, and is secured to a shaft, n, to the upper end of which is secured a hand wheel, o. p is a pin used for locking the drum in any desired position, which pin is operated by a treadle, q. L, I/, are bars loosely attached at their lower ends to tlie outer ends of the arms, H, H', and their upper ends arc loosely attached to the opposite ends of a guide bar, M. This bar, M, can slide freely up and down in guide slots in the uprights, X, X', which are bolted to opposite sides of the main frame. 0 is a crosspiece secured to the upper ends of the uprights, X, N\ r, r, are brackets secured near the upper ends of the njirigkts, X, X', in which brackets are journaled short shafts which carry the gear wheels, s, s, and pinions, t, t. I', P, are rack bars secured to the bar, M, with which the pinions, (, t, engage, u, u, are pinions attached to the ends of the shafts, v, v, which shafts are journaled at one end near the upper ends of the uprights, X, N', and, extending rearward, are again journaled-in the uprights, Q. The pinions, u, n, engage with the gear wheels, s, s. The shafts, v, v, are provided with cranks, a', and upon each shaft, v, is secured a notched wheel, b'pwith which notched wheels dogs, c', engage. Risa spring bar pivoted at one end to a cross spring, S, the ends of which are secured to opposite sides of the frame, G. The rear end of this spring bar, R, is connected with a chain, d', attached to the rear ends of the bars, E, E', or to the flat ring, F. In use the scraper blade, J, can be adjusted diagonally to tiie main frame by means of the hand wheel, g, and pinion, e, which engages with the rack, K, which is secured to the ring, G. which carries the scraper blade, and by means of the pin, h, the pinion, e, and hence the scraper blade, can be locked in any desired position. The desired lateral adjustment of the scraper can be obtained by means of the hand wheel, o, drum, 1, and chains, j, and the drum, and lienee the scraper, can be locked in any desired position by means of the pin, p. The scraper blade can also be adjusted vertically by means of the cranks, a', shafts, v, gear wheels, s, pinions, t, rack bars, P, and bars, M and L, 1/. By operating either one of the cranks, a', either end of the scraper blade can he elevated or depressed Independently of the other, as the ground to be operated upon may require. The position of the scraper blade can be changed from right to left, or from left to right, by means of the chains, j, j, drum. 1, and hand wheel, g, so as to deliver the earth either outside or inside of the wheels, and as may be required by the various classes [196]*196of work to be performed. The position of the scraper blade may be changed so as to throw the earth either to the right or to the left, and all of the necessary adjustments can be easily and. conveniently made, by means of the devices Shown and described, by an operator suitably located on the machine. The springs, E and S, sustain a portion of the weight of the scraper blade and Its attachments, thus making it more easy to adjust the blade vertically without interfering with its lateral movement.
I am aware that letters patent of the United States have been issued (one, No. 363,342, dated May 17, 1887; one, No. 370,035, dated September 27, 1887; and one, No. 370,806, dated October 4, 1887), and I do not intend to claim as my invention anything which is shown and described in either of the said patents. Neither do I intend to claim broadly the use of chains .for the purpose of giving lateral adjustment to the scraper.
