PORTABLE DERRICK.

SPECIFICATION forming part of Letters Patent No. 482,528, dated September 13, 1892. Application filed June 25, 1892. Serial No. 38.045. (N model.)

To all whom it may concern.-

Be it known that I, GEORGE V. PATNOE, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois,

5 have invented new and useful Improvements in Portable Derricks, of which the following is a specification, reference being had to the annexed drawings, four sheets, in which- Figure 1, Sheet 1, is a longitudinal eleva- IO tion of a derrick in which is embodied my invention and improvement, with the wheels of the truck removed; Fig. 2, Sheet 2, a vertical central longitudinal sectional elevation of the same; Fig. 3, Sheet 3, a plan or top View %f Fig. 1; Fig. 4, Sheet 4, an end elevation of The nature, construction, and operation of my improvement in derricks will be fully comprehended by the following detail dezo scription.

My purpose is to constructa derrick which is mounted on a truck, and thus can be made available for general light work in stone-yards, but more especially in yards or works Where the stone handled is to be crushed or broken and is to be speedily handled.

A 13 represent the bolstersupports, by means of which the bed of the derrick is mounted on two axles 17 17 and wheels 14.

F F F represent three angle-irons, which are even distances apart and are firmly secured to the bolster A B and support all the operating devices above, and they are also securely bolted to an angle-bar 12 underneath, 3 5 which is placed transversely to the longitudinal bars F, and its ends project out from the bars F at both sides of the derrick. An angle-bar D is joined to each outer bar F at E, so as to swingin eitherdirection and to serve as a support to prevent the tilting of the derrick when loaded, and to relieve the joint from undue strain a sliding stirrup 11, Fig. 4, is made to inclose the support D and the pro jecting end of the bar12, and under the outer portion of each support is placed a prop 13. By detaching the stirrup 11 by sliding it out on support D the latter may occupy positions at other angles relative to the bars F. To the upper faces of angle-bars F F F is securely bolted a bed-plate I, on which is formed a track for the inclined wheelsJ J to travel on.

The turn-table consists, substantially, of two lower angle-bars F F and two trussframes G G, securely bolted thereto. Thetop of the two trusses are secured by a cap-plate 5 5 9, whose ends W are turned down and bolted to the inner portions of the trusses, and Within the cap-plate centrally is placed a strong bearing 10, which turns with the truss on a pivot formed on the top end of a strong post S. This post at its bottom portions is firmly keyed in the base-plate I, and it supports substantially the whole weight of the turning portion of the mechanism, and the wheels J J may travel entirely round the bed I on a 6 5 horizontal circular track formed for that purpose; but the track and wheels serve as a guide rather than other support. Firmly secured to the inside of the top portion of one truss is a hanger-plate 14', with a boss on which is formed a bearing for a horizontal shaft 9. On the inner end of this shaft is affixed a vertical bevel-pinion U, and this pinion meshes into a bevel-pinion V on a vertical shaft Q, which has one bearing affixed 7 to a fixed plate T, which is supported by the truss and a vertical post 2 and has the other box fixed to the angle-bar F. The shaft Q is hung to have no vertical movement and on its lower portion is aflixed a pinion P, which 8o meshes into a gear-wheel O, surrounding the post S and secured to the bed-plate I.

L L are hanger-plates, which are rigidly secured to the truss at each lower portion thereof, and pivoted to them, respectively, are 8 5 the rollers J J.

The spar is composed of two plates M N, so forked at their lower ends M that each fork lies against a truss-plate and so that both forks are pivoted to the two trusses by one 0 rod or shaft h, Fig. 4. The outer end of the spar is provided with a sheave f in the ordinary manner and is supported and adjusted, as described, by a wire rope or chain c, attached to outer portion of the spar, brought 5 over the cap-plate 9, and secured to sliding collar 5 on shaft S, and round the shaft above the collar is placed a sliding ring 3, which is held in any desired fixed position on the shaft by a set-screw 4.

Y is a drum, to which is rigidly affixed a gear-wheel X. The shaft of the drum has bearings secured to the inclined sides of the truss. Apinion Z meshes into the gear-wheel X, and its shaft also has bearings secured to the inclined side of the truss, and cranks a b are affixed to the shaft to be turned to rotate the drum Y.

d (I represent a simple form of tackle for elevating stone.

L' 2' 1' represent a Y-shaped clutch, the upper prongs of which are pivoted to the rod or shaft h, so as to swing, Figs. 2 and 4, and the lowerend consists of two jaws, which may engage either of the bars F, and thus lock the truss as a fixture to preventa swinging movement of the spar.

K K represent the angle-irons which are employed by means of suitable bolts to support the ends of the bars F F.

7 represents a brace, two of which are required to be attached to the cap-plate 9 and the base F when the derrick is required to raise very heavy loads.

To turn the spar round, raise the clutch z' 2' 2' and turn the shaft g by placing the crank a thereon. Then reset the clutch. The further operation is not essentially different from that of other derricks.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. In a portable derrick, the three anglebars F, mounted on the bolsters of a truck, and lateral supports hinged thereto, in combination with a fixed under cross-bar and a slidable stirrup embracing both the bar and the support, as and for the purpose specified.

2. The combination of the spar with a rotating truss, a central bed-plate, and a central post-support, rollers interposed between the truss and bed-plate, and a slidable collar 5 on the post, a sliding adjustable ring on the post above the collar, and a supporting-rope attached to the collar and to the spar, as and for the purpose specified.
