HOISTING APPARATUS.

Application filed January 6, 1914 Serial No. 810,646.

The object of the invention is to provide an apparatus especially designed for transferring ashes from a cellar to a cart or other receptacle on the street level, and for analogous light service, in which the apparatus when collapsed will require but little ver-' tical space, and when extended will permit the load to be lifted sufficiently above the street level for easy deposition in a cart, and so constructed as to be economically manufactured and installed, and easily and safely operated, in the limited space usually avail able for such structures.

The invention consists in certain novel features and details of construction and ar rangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show the invention as it has been carried out in practice.

Figure 1 is a sectional view of the hoistway, showing the apparatus in elevation in the collapsed condition. Fig, 2 is a corresponding view, in the extended condition. Fig. 3 is a plan view. Fig. 4 is a vertical section, partly in elevation, showing the upper portion of the apparatus in the extended condition and on a larger scale. Fig. 5 is a plan view of a brace employed to steady the apparatus when in operation. Fig. 6 is a vertical section, partly in elevation, showing a portion of Fig. 4 on a still larger scale.

Similar letters of reference indicate the same parts in all the figures.

M is a hoistway below the street level, shown as having a cover M which may be understood to be the usual horizontal doors.

A is a hollow post set in the floor of the hoistway and held in the vertical position by fixed braces A secured to the adjacent wall. It carries an elevating mechanism consisting of a frame D in which is acrankoperated shaft C Carrying a pinion C in mesh with a gear wheel 0 on a shaft C on Specification of Letters Patent.

which is mounted a lac eend" ing through a slot in the post and meshing with a rack B on a core B inclosed in and secured to a tubular standard B arranged to slide telescopically in the post. When fully raised the standard is supported positively by inserting a pin A through suitable holes, not shown, in the post below the lower end of the standard and upon which the latter I rests. The upper end of the standard is inclosed by a sleeve K arranged to rotate on the standard and having at. its upper end a vertical coupling K in which is screwed a bifurcated head K carrying a tubular cranearm or jib L pivotally mounted on the bolt K and capable of swinging vertically thereon,

At the upper end of the standard B is a plug B having a plane upper face upon which rests the lower plate of a horizontal ball-bearing B the upper plate of which receives the plane under face of the head K and thus supports the sleeve with its connections antifrict-ionally'upon the standard with freedom to rotate thereon when required. On the lower end of the sleeve is a reducer K adapted to embrace the standard closely, and A is a similar reducer on the upper end of the post A, serving as a guide for the standard.

Mounted on the sleeve K is a frame F carrying a winding mechanism having a drum F and brakedrum F operated by a crank F It takes up the rope lV extending over the sheave L and carrying a hook W by which the ash can V or other load is hoisted, and has a pin F arranged to extend through the sleeve into the standard and thus hold the sleeve against rotation during the hoisting operation, and to be withdrawn to permit the sleeve and its load to be rotatedv in depositing the load.

The jib L is slotted to receive the sheave L at its outer end, and also carries a strut J pivotally connected to the jib on the inte rior of the latter at 71:, and having its tubular free lower end constructed to serve as a socket in connection with a spur H mounted on a yoke H secured to the sleeve K. The jib is slotted as at Z to permit the strut to swing therein to the extent required, and

when the jib is, raised at an angle and its Fig. 1, the jib drops at an angle, with the v strut depending idly therefrom, but when the apparatus is extended, the jib is lifted by hand and the strut seated on its spur, and a considerable additional elevation of the load is attained without increasing the normal height of the apparatus, an important item in mechanism of this class in which the available height of closed hoistway is usually limited.

To facilitate the lifting of the jib with its sheave and strut to the desired angular position, a sliding bar S3 is inclosed in the tuba lar jib, arranged to be drawn out through the head K as shown in dotted lines in Fig. i, and serve as a lever by which the jib may be swung upwziirdly on the bolt K as a fulcrum; when thus elevated the strut swings by gravity toward its spur and is easily engaged therewith. The bar S may then be thrust into the jib so as to be out of the way of the operator, and held against accidental withdrawal by any suitable latch, shown as a loop or ring loosely mounted in the outer end of the bar, engaged upon a hook T on the coupling K or on any convenient portion of the sleeve. The pin l serves in holding the hoistingmechanism firmly when required, and on withdrawal permitting the sleeve to rotate on the ballbearing B and carry the load to any point in the are described by the jib.

The length oi? the standard is so proportioned relatively to the length of the post A. as to rest upon the interior of the cap A which is screwed upon the lower end of the post, when the standard is in its lowest collapsed. position, coming to rest on such cap when the reducer li on the sleeve reaches or nearly reaches the reducer A on the post, so that no vertical space is wasted and the desired height of lift is attained with a comparatively short post and standard.

To steady the standard laterally during the hoisting operation, a. removable brace is employed consisting of the arms R R pivotally connected to the adjacent wall. of the hoistway at any available high point thereon, as at r 7*, each carrying at its outer end a semicircular portion l tadapted when brought together about the standard to form a ring inclosing the latter, and be clamped thereon when the standard is elevated and aid in maintaining the vertical position.
