WAGON-HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 313,803, dated March 10, 1885.

(No model.)

To all whom it may concern/.-

Be it known that I, JAMES E. BIRD, a citizen of the United States of America, residing at La Monte, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in \Vagon-Hoisting Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention is an improved hoist, more especially adapted for country use, and embraces the following novel features: A leverbeam working upon the top of a pivot-standard, and having on its burden end an intercrossing bar, to each end of which is mid-hung. a transverse swing-bar, to the ends also of each of which are attached a pair of pendulous rods, which have their lower ends bent into hookeyes, in and between which knotted bearinglashers are end-caught and swung; also, on the power end of said leverbeam a fixed pulley, and on the counter end an extension-bar, to the outer end of which is fastened a regulative rope; also the beanrstandard, having its foot cut into a long and square tenon, thelower portion of which is tapered to a blunt point, and extends for a suitable distance below the bottom of the standardsleeper, into which said foot is stepped and mortised; and, finally, a steadying-post is mortised into the end of said sleeper,directly below the outer end of said extension-bar, and into the other end of said sleeper there is set a counter fixed pulley, through sheave of which, together with that of the pulley overhead, the lever-beam-tackle fall is rove, all of which and their purposes are hereinafter more fully described, and illustrated by the accompanying drawings, in which like letters designate identical parts of my invention in the different figures, respectively.

Figure 1 is a perspective elevation of my device, showing the several parts of the same in normal position and ready for use; and Fig. 2 is an end section of the lever-beam, showing the intercrossing bar, its transverse swing-bars in section, and sectional portions of the bearing-lashers.

The letter A represents the lever-beam, and B the sleeper, into which the beam-standard P and the steadyiug-post O are respectively I mortised. Said beam is made of suitable timber of proper size and length, and squared. It is fitly mortised, so as to tenon-pivot upon the top of the standard P, and make the power-conuective arm of the lever-beam normally overbalance the burden arm, together with its elemental parts, as shown. This may be done either by making the powei arm consid erably longer than the other arm, or by counter-weights. The burden-arm of said leverbeam is furnished with an intercrossing bar, (1, which is made of suitable timber, cut square, flush-jointed at the middle into and squarely across the beam end, as shown, and has both of its ends extended and braced squarely outward, so as to suitably suspend, at a proper distance apart, a pair of transverse swingbars, f, to the ends of each of which are suitably coupled the pendulous rods g, which in their turn having their lower ends bent into the hook-eyes h, serve to hold in suspension, as shown, the knot-catching lashers Z, together with any burden which may be adjusted and triced upon them. The standardpost 1, upon which said lever-beam is pivoted, is a correspondingly-squared piece of timber of suitable size and length, and furnished at the top with the pivot-tenon 15, whereby the standard and beam are pivot-jointed, and at the foot with a stepping-tenon, t, by which the standard is mortised and vertically supported above the sleeper B, while it is equally supported below said sleeper by the tapering elongation of said foot-tenon, as shown, being thrust into a suitable post-hole made in the ground directly under said standard-mortise.

The sleeper B, into which the post 1? is I stepped and chiefly supported, is a suitable piece of ground-timber cut square, of suitable size and length, and is suitably located either upon the ground, in the flooring, or wagonway of a barn or other storage-house of a farm, or sufficiently below the surface of said wagonway to protect the material of said sleeper or sill from harm or wear. The post 0 is inortised also into said sleeper and counterbraced, as shown, in a vertical position, and directly below the end-or the outer end of the extension-bar nof the lever-beam A, which purposely gives additional steadiness to both standard and sleeper. Said BXtQdJSlOlLbiLI is suitably dovetailed endwise into the burden as shown, to be readily end of the lever-beam,

adjusted in place, and provided with a suitable ring-bolt, to which is secured the upper end of the regulative rope T, which serves to lower or loosen the normally overweighted end of said beam, and to make fast the same, as shown, to a cleat suitably fixed upon said hitching-post.

In order to suitably and co operatively Work said lever-beam, so as to raise any Weight or burden lashed between the hanging rods 9, a fitting tackle is provided, which consists of a fall rove through the sheaves of a pair of fixed pulleys, p and 10, respectively counterplaced, the one in the power-connective end of the lever-beam, and the other directly'be-- low in the end of the standard-sill.

The operation of my device is as follows: WVhenever or wherever necessary or desirable to be intermittingly raising any unhandy bur den-for instance, an overweighty wagon body, or a load of timber-from its carrier or running-gear,saidgear is run under the burden-arm of the lever-beam A, the counterpendulous rods 9 are swung outside said body or load, the lashers Z suitably passed underneath the same and caught by any of the said latchet-knots in their respective hook-eyes h.

Then loosen the rope r and haul upon the aforesaid tackle-fall of the pulleys p and p, when, said burden having been raised the desired distance, the carrier can be run out, leaving the burden suspended upon said lashers. \rVhenever desirable to lower said burden upon its own or another carrier, the reverse order of the hoist will be practiced. Thus the above-described machine supplies a very convenient, economical, and effective hoist in any of the oftentimes-required processes similar to those above stated, and in p aces remote from the means usually obtainable in such cases. Again, in order to give greater conveniency and practical effectiveness to said hoist, a duplicate of the aforesaid suspensory portion of the same may be counter-adjusted upon the power-arm of the lever-bean1,which will allow the lifting-tackle to be more easily worked by merely balancing the counterburden weights, and will double the capacity of the above-described mechanism, without changing or limiting the characteristic features or elements of my invention. Therefore,

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the lever A, the standard P, and the sill B, of the intercrossing and suspensory bar d, supplied with the swing-bars. f, the pendulous and hook-eyed rods and the knotted lashers Z, and made adj ustably cooperative with the lifting-tackle p and p, and the counter-working rope 1*, substantially as and for the fied.

2. The combination of the lever-beam A with the standard P, having the pivot-tenon t and the supporting-tenon t, and with the sill B, having the counter-braced post O, substantially as and for the purposes herein specifled.

3. The combination, with the intercrossing and suspensory bar d upon the lever-beam A, of the suspended swing-bars f, the pendulous and hook-eyed rods 9, and the knot-catching lashers l, substantially as and for the purposes herein specified.

4. The combination, with the lever A, the pivot-standard P, and the sill B, of the lifting tackle p andp, and the counter-working rope I r, substantially as and for the purposes herein specified.

' In testimony whereof I affix my signature in presence of two witnesses.
