DERRICK.
SPECIFICATION forming part of Letters Patent No. 345,478, dated July 13, 1886.
Application filed February 6, 1886. Serial No. 191,103.
T0 at whom it may cor warm:
Be it known that I, WILLIAM J. BLUNDELL, of the city, county, and State of New York, have invented a new and Improved Derrick, of which the following is a full, clear, and exact description.
The invention consists of the construction, arrangement, and combinations of parts, all as hereinafter described and claimed.
Reference is to be had to the accompanying draw1ngs,formingapart ofthis specification,i n which similar letters of reference indicate corresponding parts in all the figures.
F1gure 1 is a broken front elevation of a derr1 ck having my improvement applied thereto. F gs. 2 and 3 are opposite detail sectional news showing the preferredconstruction of the means for shifting the derrick on the line m and w m respectively. Fig. 4 is a sectional detail elevation taken on the line m m, Fig. 1. Fig. 5 is a similar view taken on the hue y y, Fig. 1. Fig. 6 isla sectional View of the upper part of the derrick, taken on the line z 2, Fig. 1.
A A represent the main uprights of the derrick, which rise from the platform or base B, and are connected by the cross pieces or rods 0 G and top crossbar, D, in the ordinary way. The base B is provided at one end with a plain wheel or roller, E, and at the other end with a roller, F, formed or provided With cogs f, by which it may be revolved for shifting the derrick. The periphery of the wheel F is provided with ribs or projectionsf, which prevent the wheel from slipping.
The wheel F may be revolved byvarious means; but I prefer to employ the upright shaft G, j ournaled in suitable bearings, and to which a bevel cog-wheel, g, is attached,wl1 ich meshes with the cogs f, formed upon or attaehed to the wheel F, as shown clearly in Figs. 2 and 3. The upper end of the Vertical shaft G is provided with a crank or crankwheel, G, having ahandle, g,for-conveniently revolving the shaft G, which will communicate rotary motion to the wheel F and cause it to move the derrick. The hoisting-rope H of the derrick passes over a pulley, I, attached to the cross-bar D, and thence over the hoistingdrum J, which is revolved by the main crank-shaft K and cog-wheels L M in usual manner. The shaft J of the drum J is journaled in the bearings N N, which are made in two parts and adapted to be easily opened for removing the drum from its bear- (No model.)
ing, which enables the derrick to be more easily transported, and the main crank-shaft K is journaled in bearings O O, which are also made in two parts, and adapted to be opened for detaching said shaft from the derrick. The bearings N O are each constructed of a pillow-block, a, and a cap-piece or keeper, a, hinged to the pillow-block a by a suitable hinge, 0, so that the cap-piece or keeper a may be opened or closed for easily removing and replacing the shaft in its bearings. The pillow-block a of each bearing N O is formed or provided with a stud, c, to which the cap-plate a may belocked, when the same is closed, by a pin or key, 0, passed through an orifice made in the said stud c, as shown clearly in Figs. 1 and 4, so that any power applied to the crank it of the crank-shaft K, or strain that may be brought upon the drum J, cannot dislodge the crank-shaft K or shaft J from their bearings while the keys are in place. To one of the uprights A is pivoted the pawl d, which is kept in place and guarded, when swung t-oa vertical position,by strap a. (Shown in Fig. 1.) The pawl (Z is adapted to engage with the cogs of the small cog-wheel L for locking the shaft K and the drum J, so that the load being hoisted by the derrick may be stopped in the course of its ascent and held at any desired position, and to the cross-rods 0, which unite and brace the uprights A A, I secure the parallel bars I? P, to which are attached horizontal cross-pieces h h, which constitute, together with the parallel uprights P, a ladder by which a person can easily ascend and descend the derrick.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The platform 13, provided with the uprights A and supported at one end upon the plain wheel or roller E, and provided at the other end with thetractive roller F, formed with a beveled gear, f, in combination with the vertical crank-shaft G, andthe beveled pinion g, secured thereon, the shaft G being journaled in and above an opening in the platform, so that the beveled pinion meshes with the beveled gear f of the tractive wheel G, substantially as and for the purposes set forth.
WILLIAM J. BLUNDELL.
