IMPROVE!) HOISTING-APPARATUS.

The Schedule referred to in these Letters Patent and making part of the'same.

'To all whom it may concern:

same, reference being had to the accompanying drawings, forming part of this specification, in whichm Figure l is a front elevation or" the improved hoistin g-apparat us.

Figure 2 is a vertical transverse section of the same. Figure 3 is a detail horizontal section of the elevator orhod-rack. l l Similar letters of reference indicate corresponding parts.- f l This invention relates to a new and improved apparatus, which is adapted for elevating building-ina teria] from the street, or from a lower to an upper story of a building, in portable receptacles, and which is so r constructed that the laborious part of the operation can bc performed by horse or steam-power, as will be hereinafter described.

Another object of the invention is, to so apply an elevator or bod-rack, which is adapted for receiving port-able receptacles or hods, to an elevatingapparatus, that said rack will be automatically caught and retained in an elevated position when carried up to its fullest extent. as'will be hereinafter described.`

In the accompanying drawings- A A represent two vertical guides or posts, which are sustained iu an upright position by means of the iioor-joists end cross-beams, which are secured thereto, or by other suitable devices.

.llhe pivots may also be substituted by r'opcs that can be stretched in any suitable manner.

The upper ends of the guides A' A are secured to a frame, B, which may be arranged to any one or two sheaves, a b, over which passes a rope or chain, c.

One end of said rope or chain is suitably connected to. a hed-rack, Cl, which is, or should be, grooved at theends to receive the edges of the guides A A, so that these guides will keep thc rack in a proper horii zontal position while itis being elevated orlcrwered.,l

The opposite end of said rope c is carried down and connected to admin, f, which is hung or keyed to a shaft, gz, that has its bearings in a frame, l), or in the lower parts of thc posts, or in amis projecting therefrom.

This frame should be so constructed that it can be readily secured in place, and removed whenever'it is found necessary;

" A draughtrope, h, may be secured to a smaller drum, 'er mountedon the shaft f/nnd is wound aroun d it in l such manner that when the rope'is unwound, by means of a horse or otherwise, it willI rotate the series shaft' g?, or at least the drum j; and wind up the rope c, upon its drum, f, thus elevating the bod-rack.

If it'is desired to move the bod-rack very rapidly,

the horse moving slowly, the ropenc may 'be carried around a larger drum', g, arranged on g.

Another drum, g1, on g2, is intended to receive a brake-strap, li, to which a rope, j, is attached.

By pulling this rope j, the brake can be drawm tightly about its drum', which will stop the bod-rack,

either in its ascent or descent.

By means of this brakearrangement the attendant can stop the hod-rack at any` desired height, or he` can regulate 'its descent. v

The arrangement for rotating the drum f or g, fnay be considerably varied, as any other suitable mechanism canbe applied to the same purpose. In fig. 2 is represented a counter-weight, c', applied to the rope c, for counterbalancingn the weight of thel hodraok and its contents, and for thus relieving the horse of much of the weight of this hed-rack. Such` counterweight may, however, be dispensed with.

At or near the upper end of the guides, and sustained by the frame B, are, or maybe, two boxes, Ick, i arranged in a horizontal plan directly -opposite each other. l

These boxes contain spring-latches m an, whiclnaro actuated by levers In n, and a rope, p, as shown in 1i r. 1. A,

These latches have their noses or catching-ends so formed as to be thrust back by the projecting ends of the top of the hod-rack, when the latter is elevated to its fullest extent, and then to spring back under said projectiiig ends, thus catching and supporting the to be elevated or lowered, may be placed directly upon" the rack.

That shown in. the drawing, is adapted to receivel the common portable hods s s s s, which are usually carried upon the shoulders of laborers.

In iigs. l, 2, and 3, are rep .sented such hods ap-f plied to the rack O, in such manner that thcycau be readily removed therefrom for iilling oremptyin'g. The rack shown in the drawing, is constructcdlas follows y t t are two horizohtalledges, securedt'o the' sides of a box, O, and notched to receive-and supportone. end of the hods.

Between theseltwo ledges t t,-is another-ledge, u,

which4 is notched on both sides` to' receive the opposite ends of the hods.v i

The notches in the ledges are of a V-shepe, und

hence preventthehodsfrom tilting when seated in them,

and at the Sametime allow the hods to be applied to or readily removed from the hodraek. The said hodmok may, however, be constructed in other suitable manner, as, for example, without a' platform; and we do not confine ourselves to the form herein shown.

The apparatus is operated b'y revolving the shaft g2, or, if the drum f is loose on it, the drum itself, thereby winding orl unwiudug the rope c, and lowering or raisthe mok C. a

The brake, when applied, Ina-ny be used to stop the ,ascent ofthe elevator at any desired height.

The rope o need not necessarily be ,woundl upon a drum,`as it may he directly applied to the elevating or loweriug-meehanism, or il; may be pulled by hand, il' desired. Whet'we claim, :is the invention of GEORGE AM- BROSE, and desire to secure by Letters Patent, ism' l. The upper catches, in eoinbimrtion wi Isla vthe hodreoks and frame all arranged with respect to erich other, :is and for the purpose specified.

2. Spring-lamelles 'fn-m, and levers n n, in eornbination with thefguidesA A, and elevator orhod-rek, C, substantially :is described. u The above specification signed by us, this 24th dey of February, 1869.
