ATTILIO B. PIATTI, OF NEW YORK, N. Y.

HOD-ELEVATOR.

SPECIFICATION forming' part of Letters Patent No. 271,118,

dated January 23, 1883.

Application filed October 12, 1882. (No model.)

` ployed, passing around a windlass at the bot- Ioni and' over pulleys at the top, and the hods are provided with hooks, so as to he hooked directly onto the links or rounds ofthe ladderchain, and thus raised by the motion ofthe chain. In the other type a car or platform is used which moves in Xed guides and is suspended from a hoisting-cable which extends to a winding-drum or hoisting-engine, and the hods are placed directly on the car. My invention applies to this latter form ot' hed-elevator, and it aims to so construct the parts as will support the hods firmly and yet admit of their very quick and easy placement on and removal from the car, and also to insure the smooth and easy motion ot' the carin the guides.

To these ends my improvements may be stated to consist in brace rods or rails rising from the car in position to admit the handles of the hods. between them, while the hod reclines against the top cross-bal" of the carin cups or sockets near the outer edges of the car, between said rails, to receive the ends of the reclining-bod handles; also, in certain arrangement of guide-rollers and slides at top and bottom of the car, whereby a smooth, easy movement ot' the car in the guides is insured, notwithstanding the fact that the car may be tilted in the guides or bear unevenly therein, dueto a greater weight on one side than the other, as hereinafter fully set forth.

Figure l of the annexed drawings presents a front elevation of my improved bod-elevator,

` showing hods placed thereon. Fig. 2 is a` cross-section of the same on .r m. Fig. 3 is a sectional plan on line y y of Fig. l. Fig. 4 is a vertical section through the upright frameheam of the car at the guide-roller and slide. Fig. 5 is an inner view of the roller and its box or bearin g.

In the drawings, a c indicate the fixed ways or guides in which the elevator-car B moves.

c d indicate the base or platform of the car, which is preferably formed of a ystrong marginal wooden frame, c, joined transversely by a number of cross slats or beams, d, which are placed at such intervals as to leave slots or yopenings of about their own width, which al-v low any mortar overiiowing or slopping over from the hods-to fall through Vto the bottom of the shaft, and thus prevent accumulations on the platform.

From the ends ofy the platform strong upright beams arise in line with the guides a, and of about equal width, as seen in Fig. 2, and these uprights are connected near the top by the crossbeam or head-piecef of the car, to the center of which the hoisting-cable g connects, as shown in Figs. l and 3. The cable does not connect directly to the head-piecef, butto an iron rod, h, which has an eye or socket on its upper end to receivethe end'of the cable, and which passes down through the center of the cross-beam, and is threaded to receive the nuts i i, which embrace the beam between them, and thus rmly connect the rod with the beam, as seen in Figs. 1 and 3. The rod his reduced in diameter below the head-'beam f, and is thence continued down through the central bar, oi, in the platform, andits extremity is threaded to receive a nut,j, which hears upon the under side of the platform, so that the rod thus makes a firm suspensory-connection from the cable with both the top and bottom of the car. The reduction in the diameter of the lower portion ofthe rods is for the purpose of readily admitting the nuts, as will be understood.

Now, the car is made preferably of such a size as will admit two hods on each side ofthe head-beam, as seen in Figs. 1 and l3, the design being such that the hods, when placed on the car, will rest against thehead-beam, so as to recline thereagainstby their own gravity, and at a sufcient inward inclination to render their position quite tirm and stable, as willbe understood from Fig. 3. The degree ofinward inclination of the hods will be determined by the width of the platform, and in order to give the hods the greatest available degree of incliuation the ends of the bod-handles are sup- IOC v I i ported at the extreme edge of the platform in depressed sockets or cups k 7c, sunk into the marginal frame of the platform, as shown best in Figs. 2 and 3. The cups 7c are preferably made of cast-iron, suitably screwed or fastened in the platform,with their front and sidewalls perpendicular, to form stops to receive and restrain the ends of the hed-handles, and with their bottoms inclined upwardly and inwardly, so that when the bod-handle is inserted in the cup it will at once slide down the incline against the upright side of the cup, and thus allow the hod to recline firmly against the head-beamat its utmost inclination, while firmly holding the hod on the platform at this inclination, as will be understood. The cups 7c thus firmly support the vertical strain of the hods, -Whiley the head beam j supports the lateral strain thereof, due to their inclination against the same, which being equal on each side of the head-beam, there hence exists no tendency to force the beam one way or the other.

Bracketsl project from the middle of the head-beam on each side between the hods, and also from the uprights b b on each side at the outer ends of the hods, and thus efi'ectually prevent the longitudinal .displacement of the hods, as will be readily appreciated, while the straight vertical sides of the cups k prevent the possible displacement of the hed-handles at the base, thus rendering the arrangement of the-hods very secure. The position of thehods is still further secured by guard-rails or bails m fm, which rise from the platform on either side of the bod-handles, and are braced at the middle by a brace-rod, n, which extends longitudinally across the center of the car at one side of the central rod, h, and is fastened at each end to the uprights b of the car, as

fully shown in Figs. l and 3.

'.l`he rails m and brace-rod 'n may be formed of iron pipe and pipe-fittings, or of rod-iron forged into the proper form, and the ends of the rails are of course firmly secured to the margins of the platform on each side of the cups 7a, as best shown in Figs. l and 2.

It will be noted that the rails are arranged in pairs at each set of cups, the rails of each pair being sufficiently separated to readily admit the hod-handle between them, and the rails rise to a height above the platform, preferablyjfrom one-half to two-thirdsthcheight of the handles, so thatthe exposed part of the handles above the rails admits of being readily grasped by the hand in placing the hods on the'car or removing them therefrom, as will be understood. It may therefore be now seen that the constructions for receiving, holding, and steadying the hod on the car are very simple and secure, Without requiring any addition to the hods or any special construction thereof,and are of such a nature that the hods can be placed on the car or removed therefrom very easilyand quickly Without detaching any fastenings, which greatly facilitates the work of supplying the building materials, and reduces, as far as possible, the chances of loss or accident in the handling of the hods.`

Referring to Fig. l, it will be noted that the uprights of the carproject some distance above the head-beam f, and near the top of these uprights rollers o o are mounted thereon and project through openings therein and bear upon the guides a c. A second set of rollers o o are mounted in a similar manner in the lower ends of the uprights and bear upon the guides near the base of the oar. This second set of rollers is preferably placed just above the platform; but they may be placed below the platform if the uprights b project below the same, as will be understood. These rollers, as may now be seen, in bearing upon the guides, prevent the uprights or the platform from making direct contact therewith, and thus form a rolling-bearing between the car and the guides, which avoids friction and insures a smooth and easy motion of the car and greatly reduces the wear of the guides. It may also be noted that as these rollers are placed at nearly the extreme top and bottom of the car, hence, no matter howv much the car might tendv to tilt in the guides by being loaded heavier on one end than the other, two rollers at diagonally-opposite corners will always bear upon the guides and prevent any sliding contact of the car therewith, thereby insuring a smooth and easy motion, even when the car is unequally loaded and slightly tilted, and thus avoiding the jerky motion which ,commonly occurs under the same conditions with the car as heretofore equipped, and which tends to displace the hods or spill the contents.

In addition to the rollers o, clasps or slides p p project from the uprights b upon each side of the guides, and thus prevent the lateral motion of the car in the guides, as will be understood. Instead of these clasps, rollers similar to the rollers o may be employed; but the clasps are deemed preferable. These clasps p are preferably formed of cast-iron-screwed to the outer face of the uprights b, and they are preferably located on the uprights at top and bottom, coincident with the rollers. o o, the peripheries of which project through an opening in the base-plate ofthe clasps and bear upon the guides at the middle of the clasps, as best shown in Figs. l and 4, while the guide-rollers are journaled in a metal plate which is screwed to. the inside of the upright coincident with the base-plate of the clasps, as also shown in Figs. l, 4, and 5. The construction and attachment of the rollers and clasps are thus very simple and strong.

I do not wish it to be inferred that either clasps or rollers on the car are new in themselves; but usually-the rollers have been located at or near the middle of the car, or at one end only, and not at the extreme top and bottom of the same with coincident clasps, as in my case, so that in the former arrangements the tilting of the car would cause either top or bottom to make IOC IIO

mao

sliding contact with the guides, and. thus produce great friction, which obviously cannot oc cur in my arrangement. I would also remark that clasps are of course commonly used to embrace the guides, and at top and bottom of the car; but they have not been used with rollers in coincident position, as in my case, which is a nfuch more simple and compact arrangement, and is also stronger, as the clasp serves to strengthen and brace the uprights Where they are perforated to admit the rollers.
