To-aZZ 'whom t may concern:

Be it known that I, CHARLES K. ERNST, a

citizen of the United States, residing at Buffalo,in the county of Erie and State of New York,have invented a new and useful Improvement in Hoisting Apparatus, of which the following is a specification.

- vThis invention relates to improvements in *hoisting apparatus of that kind which is intended more particularly to be used in hoisting ashes and other material from a cellar or vaultv to the side-walk or Hoor above the same.

Theobject of this invention is to provide an apparatus of this kind which will be simpleand inexpensive in construction, which can be easily installed in the vault or cellar and will occupy comparatively small space therein, which when not in use, stands concealed beneath the side-walk or floor where it is kout of the way, and which can be easily raised to a hoisting position in which it projects above the side-walk and in this position can be readily operated for raising articles from and lowering them into the cellar.

In the accompanying drawings, consisting of two sheets: Figure 1 is a side elevation of i a hoisting apparatus embodying the invention, showing the same in its lowered position. Fig. 2 is a similar view ofthe apparatusin its hoisting position. Fig. 8 is a frag-v `mentary front elevation thereof. Fig. 4 is a fragmentary sectional elevation, on an enlarged scale, of the apparatus as shown in Fig. 1. Fig. 5 is a top plan view of the apparatus. Fig. 6 is a cross-section thereof in.

1s in its hoisting posi- Like yreference characters refer to like parts in the several figures.

The hoisting apparatus comprises right supporting member A which an upis secured in the vault or cellar beneath the openinginthe side-walk or floor, and a hoisting member B which is slidably mounted on the support A and can be elevated to project vvof the member B throughout its length.

up through the opening andform a hoist for raising articles through the same onto the side-walk. The support A is of channel.- shape having a central web portion a and parallel edge flanges a a', and the hoisting member is of T-shape and is arranged within the channel portion of the support A with its oppositely extending flanges in engagement with the inner face of the web a and its central flange projecting outwardly away from this web.

The hoisting member B preferably consists of two angle bars which extend parallel with each other and are secured together in such a manner as to form oppositely extending flanges b b which engage the web a, and parallel flanges b b which project outwardly therefrom and are spaced apart so as to leave a continuous open slot or channel between them which extends longitudinally The angle bars may be secured together in any suitable manner, as by a series of bolts b2 which connect the flanges o b and have spacing sleeves b3 which are arranged on the bolts between the flanges and retain the bars in their spaced position.

The hoisting member B is-adapted to be moved endwise of the supporting member A and for the purpose of retaining it in sliding engagement therewith, thesupporting member is provided near its upper end with suitable guide-ways c c in which the flanges b b of the member B are adapted to travel. These guide-ways may be formed in any suitable manner. In the construction shown, angle irons C C are employed for this purpose, each being riveted or otherwise suitably secured at one flange to the inner side of one of the edge flanges a with its other flange spaced a sufficient distance from the web a to admit oneI of the flanges b and form a guide therefor.

The supporting member A stands in an upright position in the cellar and is preferably secured in such' position so that it can turn freely in a horizontal direction. Any suitable meansy may be employed for this purpose. That shown comprises a base plate D upon which the support A rests and with which it has pivotal connection by means of a dependingpost d which engages in a hole in the base plate, and a hinge D of usual construction which connects the upper end of the support A to the side-wall of the cellar, being preferably bolted or riveted to the frame which surrounds the door or opening therein. This permits thelioisting member which is carried by the supporting member to be turned in a horizontal direction in both its raised and lowered positions and prevents any undue strain and stress which would otherwise fallv on the supporting member if the hoisting member could be turned independently thereof.

Any suitable means may be employed for elevating the hoisting member to its hoisting position and returning it to its lowered or telescoping position. In' the construction shown, a rope or cable E is provided which is secured at one end to the lower end of the hoisting member, preferably to the lowermost spacing sleeve '53, and extendsupwardly in the open space between the iianges Zi to a pulley e which is suitably journaled in an opening in the web a near the upper en d thereof. The rope E passes over this pulley and downwardly at the rear of thesupporting member A and over suitable intermediate swivel pulleys e and e2 to a winding drum c3 which is journaled in a frame or support F which stands on the floor adjacent to the baseplate D and which is adapted to be turned forl winding therope E thereon for raising the hoisting member to its elevated position, as shown in Fig. 2,

having for this purpose an end extension for a crank handle and the usual ratchet to prevent its unwinding.

.The supporting member A has suspended therefrom a pin Gr and its side fianges a a are provided near their upper ends with holes or openings g 'through which this pin is adapted to extend. When"r the hoisting member has been raised by means of the rope E and windingzdrum e3 to its elevated positionthe pin G is inserted in the holes g -so that it -bridges the space between the flanges a. a beneath the lower end of the hoisting member and forms a stop or suport for the hoisting member, as shown 1n Fi 8. This relieves the elevating rope and its drum from the weight and strain to which 'the hoisting f member is subjected when inuse and brings the same directl upon the supporting member, Whichfis su ticiently strongto withstand it. The open longitudinal slot or opening between the flanges b b of -the hoisting member permits the rope E to travel freely therein and to pass over the pulley e without interference as the hoisting member is being raised and lowered, while at the same time the engaging faces of the members A and yB can be made to fit snugly together throughout' their length.l

The hoisting member is provided upper endI with a laterally extending :i

H which is preferably `formed of two par? allel angle bars h h which are connected together by bolts h 7L in such a manner as to leave a longitudinal slot or opening between them, a'nd are secured at their inner ends by bracket plates h2 to the upper ends of the spaced angle bars which form the hoisting member. In the slot or space between the angle bars h, at the outer end of the arm, is journaled a pulley 'a' over which passes a hoisting rope or cable I, one vend of which depends therefrom and'has a suitable attaching device "for securing it to the ash cans or other articles to be raised. Ihe other end of. the hoisting rope passes from the pulley t over a pulley 2 journaled in the bracket plates h2 at the junction of the arm H with the hoisting member, thence downwardly at the front of the hoisting and supporting members and over 'intermediate swivel pulleys is and 4 on the base plate I) and the frame F, to a winding drum 'K' which is journaled winding drum K has, at one end, .the usual in the frame F. The

extension to which a crank handle can be fitted for turning the same, and at its other end is geared to an auxiliary shaft L which is journaled in the frame F and can be turned for rotating the drum. When the hoisting rope carries but a medium weight, it can be easily raised by applying the power directly to the winding drum for rotating the latter. 'Vhen the weight is a heavy one, the power is applied to the auxiliary shaft L which by reason of its gear connection with the winding drum increases the leverage thereon and enables the weight to be easily hoisted. I i

While the described construction and arrangement of the winding and hoisting means has been found to be a simple and etlicient one, any Iother suitable means may be employed for this purpose and arranged on the hoisting apparatus and operated in any desirable manner.

The entire construction is a very simple' and inexpensive one. The supportingand hoisting members are formed from angle and channel bars of standard shapes and sizes and no s cci'ally rolledor formed bars are required or this purpose. The longitudinal slots between the angle bars which form the hoisting member and its'lateral arm form a space in which can be placed thev elevating and hoistingropes and the pulleys over which these ropes travel, thus greatly simplifying and strengthening the construction. The apparatus can be readily installed at little expense and occupies but a small amount of space in the cellar. The hoisting member can be turned in its raised position to swing its laterally extending arm over the walk, and, in its lowered position, to bring its lateral arm adjacent to the side wall of the cellar where it will not interfere with the free use of the opening' into the cellar for other purposes. As the hoisting member and its support turn together, this turning movement for changing the position of the laterally extending arm brings no additional strain upon the pin which supports the hoisting member in its raised position. y
