MATERIAL-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 739,296, dated September 22, 1903.

!Application filed August 1, 1901. Renewed June 29, 1903. Serial No. 163,662. (No model.)

To all whom it may concern:

Be it known that I, HENRY GULL, a citizen and others in elevating brick, mortar, or like material in hods. Heretofore many elevators of the class described have been devised, some of which havcembraced a chain belt on which a hod or hods may hang by means of a hook permanently securedon the hod. Most ele-' vators of the class have been of considerable width, thereby necessitating a relatively large opening through the floors of abuilding where used. This is objectionable, inasmuch as it seriously interferes with the finishing of a building.

The object of this invention is to provide a cheap, simple, strong, and durable construe tion which requires but small space laterally or longitudinally of the joists and whichso carries the hod containing the material as to.

avoid entirely the dropping of mortar, bricks, or other material therefrom.

The invention consists of the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a front elevation, partly broken, of a device embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a fragmentary perspective view illustrating the construction of-the cages and ways. Fig. 4: is a transverse section through the ways. Fig. 5 is a similar sectional 'view with parts omitted, showing a modified construction of the ways. Fig. 6 illustrates a modification of the'cage guide-pulleys. Fig. 7 is a rear elevation of the top frame or head. Fig. 8 is a side elevation of'the same. Fig. 9 is a top plan view. Figs. 10 and 11 are details of the Winch.

As shown in said drawings, the elevatorways are secured on uprights A, two in number, arranged parallel and, as shown, approximately twenty-eight inches apart from outside to outside, so that when the joists of a building are set sixteen inches between centers, as usual, one of the joists of the fioor of the building may be moved over to an adj acent joist, and said uprights will'fit closely in the space thus formed.

l B B indicate the elevator cages or carsas shown, two in number and movable along ways a a, secured on opposite sides of said uprights.

The uprights may be of any desired size and of any preferred construction. As shown,

however, the same are formed from sections V or lengths of material of a desired size and adapted to be secured or spliced together in any desired manner in alinement and provided with a plurality of holes extending therethrough and spaced a given distance apart and which register with corresponding holes in the opposite upright when the device is erected. On opposite edges of each of said uprights are provided metallic inwardly-directed flanges or waysa, which may be formed either of angle-iron rigidly secured to the upright, as shown in Fig. 4; or of plates or straps of metal a, secured .on the opposite side of ach upright by bolts which pass through and through the same, as shown in Fig. 5. The holes extending through said uprights are, as shown, of two sizes, the larger alternating with the smaller. Through said smaller holes stay rods or bolts extend, onwhich may be provided a sleeve o the ends of which abut against the inner side of the uprights and act to hold the same rigidly in position when the nuts on the stay rods are set up". I

0 indicates a top or headframe, comprisin'g, as shown, the vertical members or straps of metal 0 adapted to fit closely between the ways of each upright and which afford means for rigidly securing said frame to the uprights by bolting the same thereto through said smaller apertures. Near the upper end of said straps O and C and rigidly secured to each is the transverse horizontal plate or 7 bar 0 Adjacent to the upright G an'd rigidly secured to the bar 0 is the cross beam or bar of metal 0, at theouter ends of-which v are secured the brace membersc c,tlie inner V ends of which are boltedto the plate or bar 0 adjacent to the upright O; Angle-iron ties C v connect the uprights below the frame thus formed. Braces c c, rigidly secured at their lower ends on said angle-iron ties, are rigidly secured at their outer or upper ends to the ends of the cross beam 0. Diagonal upwardly-extending braces c c, which are se cured, respectively, on the uprights C and C are connected at their upper ends with the plate or bar C near the middle thereof, as shown in Fig. 7. On the triangular frame thus formed are j ournaled sheaves D D, which are grooved to receive a cable or line and which are arranged obliquely to each other, with their like edges projecting beyond the upright to which the strap C is secured and with their planes converging in front of the same. Said sheaves may be journaledin any desired manner on said top frame or head, as shown. However, a boxing or bearing is secured on each outer end of said cross-beam C", and a shaft is journaled therein, the inner end of which is secured 011 aboxing or bearin g bolted on the plate C as shown in Fig. 9.

Journaled transversely in the uprights is the winch E, comprising a shaft E, which extends through two of the corresponding larger holes in said uprights a convenient distance above the floor from which the device is to be operated. Said shafts are provided at each end with a collar which engages against the uprights and on its end, beneath the sheaves D and D, with a grooved drum e, adapted to receive a plurality of turns of cable from said sheaves, and with a ratchetwheel e. The ends of said shaft are adapted to be engaged by the cranks 6 6 whereby the same is operated. A shaft E extends through said uprights in the next adjacent larger apertures above those occupied by the shaft E and is provided at one end with a double pawl 6', adapted to engage the ratchet c from either side, and at the other end with an operating-lever c whereby said pawl may be lifted by an operator on the opposite side of the elevator therefrom.

The elevatorcages each comprise a frame forming a rigid back wall B, having pulleys or rollers journalcd on the rear side thereof to engage the ways on one side of the uprights. A bottom or floor portion 13 is rigidly secured at the lower end of said back portion at a right angle therewith and adapted to support the hod or hods of materials. As shown, diagonal braces bare secured on said back wall and near the outer margins of the floor portion. A bracket or step bis secured to said bottom portion and to the back wall and extends upwardly at its outer end to a point above said floor portion and is provided with a socket to receive the hod-handle, as indicated in Figs. 2 and 3. A corresponding socket is provided in the opposite outer corner of the floor or bottom portion, as shown at Z2 so that each cage, as shown, is adapted to carry two loaded hods, one of which is sup ported slightly above the other.

Near the top of the back wall are the outwardly-extending Wings 13 B, arranged one above the other a distance equal to the height of the hod-head and on each side of the mid dleof the back wall. Each of said wings is adapted to support one of said hods laterally, said hods each leaning against the wing on the opposite side of the center from the socket supporting the hod-handle.

The ends of the cable or operating-line F are secured, respectively, to said cages, and one or more turns of the middle part of said cable are passed around the drum 0, so that rotation of the drum in one direction serves to elevate the one cage and lower the other, while rotation in the opposite direction reverses the operation. Preferably said cable ends are secured on said cages in alinement with the centers of gravity of the cages, as shown more particularly in Figs. 1 and 2. This may conveniently be done by passing the cable end downwardly on the outer side of the wings and securing the same on the cage-backs by taking one or more turns or hitches about cleats b If. (Shown in Fig. 1.) For the purpose of directing said line ccntrally above the wing B an arm or projection 31 (shown in Fig. 2) may be employed, on the inner side of which the line is passed before being carried around the wing B The operation is as follows: The device being mounted and adjusted as described, a hod may be supported in the socket at N, so as to lean inwardly against the back and against the wing B A second hod may be supported on the step or bracket Z) and leaned inwardly against the back and against the wing B as shown in Figs. 1 and 2. The cen ter of gravity of each of said hods now falls a considerable distance within the line of sup port, thereby acting to hold the hod by gravity more firmly in position. The loaded cage may now be elevated by means of the winch to the desired position, the other cage being by the same operation lowered. Arrived at the desired elevation, the hods may be lifted from the cage and carried to the place Where the material is needed. When the operation of building has reached a height which makes it desirable to elevate the materials to a greater elevation, the top frame may be disconnected and an additional section of the uprights bolted in position at the top of the uprights theretofore used and the head-frame secured at the top thereof, as before described, when the operation is continued as before.

Obviously many details of construction may be varied without departing from the principle of my invention.
