HYDRAULIC HOIST FOR ASH-CANS AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed June 13, 1918. Serial No. 239,701.

To all whom it may concern:

Be it known that 1, CHARLES H. FAY, a citizen of the United States, and a resident of Newark county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Hydraulic Hoists for Ash-Cans and the like, of which the following is a specification.

Hoisting apparatus in accordance with the present invention may be utilized in a The embodiment illustrated for affording an understanding of the invention is more particularly designed for lifting ash cans and the like from one floor level to another, as from the cellar or basement to the first floor of a building or to the sidewalk level,

An object of the invention is the improvement of devices of this character in numer; ous respects as hereinafter described and claimed, including, among other things, the provision of means whereby the hoisting apparatus may be operated by an operator stationed at a distance, as, for example, by an operator stationed on the sidewalk outside a hatch through which the ash cans are delivered by the hoisting apparatus; the provision of means whereby the ash cans or the like may be hoisted and swung about so as to be delivered' to one side, as upon the sidewalk adjacent to the hatch through which they arehoisted, and other objects of the invention will appear in connection with the following description and be pointed out in my claim, and with these and related objects in view, my invention 'consists of the parts, improvements and combinations herein described and claimed.

In the drawings forming part of this specification is illustrated such an embodiment of my invention as above referred to, and in said drawings Figure 1 is a part diagrammatic side view of an ash can hoist. Fig. 2 is a fragmentary side view showing the hoist turned to deliver ash cans, or

other articles hoisted, at one side of a hatch.

Fig. 3 is a longitudinal, cross-sectional View of the hydraulic lifting jack. Fig. 4 is a partly diagrammatic plan view of hoisting apparatus in accordance with the invention hereof as seen through a hatch beneath which it is located. Fig. 5 is a longitudinal, cross-sectional view of a valve for operating a hydraulic hoisting jack. Fig. 6 is a similar view of hydraulic apparatus for operating the valve such as shown in Fig. 5, and

Figs. 7 and 8 are respectively detail, crosssectlonal views'of a pulley mounted in a grooved pipe and a valve for controlling the operation of the valve-operating apparatus such as shown in Fig. 6. Fig. 9 is a plan view about'in cross-section taken substantially on line 9, 9, Fig. 3.

10 designates a lower floor level, as a cellar or basement floor, 11 a building wall, and 12 a higher floor or sidewalk level provided with a hatch 13 which, of course, is preferably suitably covered or closed when not in use. 14: designates a hydraulic cylinder which supplies the power for hoisting. It may be supported in preferably erect position in any desired way, but in the form shown its base 15 is fastened to the floor 10 by bolts 16. The. cylinder 14 is closed at the lower end by the base 15 and is provided at the upper end with a head 17, the cylinder 14 in the form illustrated having the base 15 and head 17 secured thereto by screwthreaded connections. The base and the head may be secured in place in other ways.

An opening 17' is provided in the head 17 for the passage of a piston rod or plunger 18 which has secured thereto a piston designated generally by the numeral 19. The piston 19 may comprise oppositely directed flanged leathers or the like 20, 20 between which a metallic, preferably brass plate 21- is interposed, and within the leathers 20, 2O washers, such as shown at 22, 22, may be placed, and the entire piston constructed as described may be secured to the plunger rod 18 by means of nuts 23, 23. Means are preferably provided for limiting the movement of the piston 19 in the cylinder 14 so that the fluid ports will not be overrun, and to this end a collar 24. may be secured to the rod 18 above the piston 19, and the rod 18 may be extended below the piston 19 as shown at 25,'and such preferably threaded end of the rod is providedwith an ordinary pipe cap 26 or the like to provide extended contact surface. Pistons of other construction may be utilized instead of that shown, but the construction shown is well adapted for securing effective operation of the apparatus.

suitably securedtogether as by means of a series of bolts 30. The cap 27 is preferably extended beyond the head- 17 and provided with a number of openings 31, 31 in the bodiment shown, in projecting lugs or ears 32, 32. The cylinder 14 has a port 33 near its upper end andv a port 34 near its lower end and is operated by passage of fluid through such ports. When installedfin a building, as in the basement and utilized for hoisting Objects such as ash cans, ordinary city water pressure is preferably utilized fertheoperation of the apparatus, andv inasmuch as it is frequently necessary to locateat .least some part; of the apparatus below thelevel of a sewer, means are preferably provided for discharging operating fluid, as water, under pressure so that the same may be delivered at any desired point.

A form of control valve is shown in Fig,

I 5 and'comprises abalanced piston 35 mounted 7 for sliding movement in a preferably cylindrical casing 36. The. water is admitted, as at the bottom,fthrough a pipe 37,

and the two parts 38 and 39 of the piston being connected by a tubular connecting piece, such as a pipe 40, the water supply is available both above and below the valve. A pipe 41 may lead from the lower portion of the valve chamber to either of the I ports 33 or 34, while a pipe 42 from the formed in annular hollowprojecting por opposite end of the valve casing may lead to. the remaining one of the ports 33 or 34. The intermediate space 43 within the cylinder v36 communicates through a pipe 44 with the sewer. In order to obtain free passage of fluid from and to the valve cham-' ber 36 the ports thereof are preferably tions as 45, which communicate with the interior of thevalv'e' chamber, as by means of a series of port openings 46. The valve 35 is operated by suitable means provided for that purpose, and in the form shown is, actuated by a rod 47 extending through a packing gland 48 and movedby a handle 49 which is pivotedto a swinging link 50. The arrangement shown in Fig. 5 is designed for manual control by an operator located at or having immediate access to the valve 35, but other provisions may be made for operating said valve 35, as illustrated, for example, in Figs. '4, 6 and 8, and which will be referred to hereafter.

The operation of the valve shown in Fig. 5 is as follows: With such valve in the po sition illustrated in full lines, which is the neutral position, the ports leading to the pipes 41 and 42 both are closed. The valve also has two other active positions, as illustrated by the dotted line positions of the handle 49. When lowered, for example, to

the lowermost of such dotted line positions,

the pipe 42 comes into communication with a source of fluid supply and fluid is admitted thereby to either of the ports 33 or 34, p 'to which the pipe 42 may be connected. At extended portion for a purpose described below, the same being formed, in the em '43 within the chamber 36, and fluid enter the same time the remaining pipe .41 is in communication with the intermediate space ton 19 is required when communicated to the articleto-be lifted, such as an ash can. One means of securing such.increasedmovement is illustrated in Fig. 1. In such figure the plunger-18 passes through a steadying guide51 and is provided on its upper end withacross-head 52 preferably constructed of pipe. The cross-head 52 may comprise an ordinary T-joint 53 which has a swivel connection on the plunger rod 18, as,-for ex-.

ample, the rod 18 may be made hollowand the member 53 provided with a rod or pipe 54 fl tting rotatably in the top of the plunger 18. a longer arm 55 and a shorter arm 56 which are provided with pulleys 57 57'. Such pulleys are preferably mounted so that they may be adjusted upon the arms 55 and 56, as by means of screws .58, 59 or the like. The arms 55 and 56 are preferably slotted on their under sides, as shown at 60, Fig. 7, anda cable or rope 61 may take over the pulleys 57, 57, passing intermediate such pulleys within the cross-head 52, and inclosed thereby, as will be apparent from the showing of Figs. land 7. In the construction shown the cap piece 27 has a third pulley 62 secured thereto, and the cable 61 coming from the pulley 57 above passes therebeneath and has its end secured The cross-head 52 comprises to an eye 63 on the frame of the pulley 57 The bight of rope extending over the pulley 57 is provided with means of attachment to an object to be lifted, as, for example, a hook 64 for attachment to ash can bails or the like, and a weight 65 is preferably provided to insure that this bight of the rope will descend when permitted to do so, even though an object, such as an ash can, should not be attached, whereby slack and tangling of the rope may be avoided. The ar-rangement of rope and pulleys justdescribed is one which may be resorted to when a three fold multiplication of movement of the plunger rod 18 is to be obtained. If greater or less additional movement is desired, ad-

ditional or fewer stationary or moving pulw leys may be provided than as shown, as will cross-head to be turned with respect to the plunger, is of importance in that it enables ley the swinging aside, as for landing, of an object lifted by the hoist to be accomplished without turning Etheplunger 18 and piston 19, and in Fig. 2 the cross-head 52 is shown turned around on its swivel. mountin 'to land a can 66 upon the upper landing oor or surface 12. It will be noted that after the can or the like has been detached, the cross-head 52 will resume its normal position, as shown in Fig. 1, this action taking place by reason of the radial or torsional displacement of the pulley 57 with respect to the pulley 62, which is opposed by the pull on the bight of rope connecting the pulleys, and the object of providing the series of openings 31, 31 in the cap 27 will now be understood, it being desirable that provision may be made for locating the pul- 62 or for fastening the rope 61 (if, for example, the pulley 62 is dispensed with) to the ca 27 at a proper position radially of the cy inder 1 1, according to the conditions encountered in use, as, for example, the side of the hatch to which it is desired to deliver the lifted cans or other objects.

In flat buildings, school houses and the like, where there may be but a single janitor to take care of all the work about the building, it is desirable that provision be made for operating the hoist from some distance, as, for example, from the landing where the articles are to be delivered after being h0ist ed, and with a view to taking care of conditions such as this, I have devised means for controlling the operation of the lifting jack from a distance. In this connection reference may first be made to the means preferably provided for attaching the hoisting apparatus to an ash can or the like to be hoisted. The ordinary ash can has no bail, and other cans to be hoisted, as garbage cans or the like, frequently have a swinging bail which can not be utilized to good advantage from a distance. When ash cans and the like are to be used in accordance with my hoisting apparatus, I preferably provide them with bails suitable for the purpose, and the same may comprise side bars 68 secured to and projecting above the sides of the can, as shown in Figs. 1 and 2, and being provided at their ends with preferably square holes for receiving a square ended cross-bar 69 which has an upwardly directed loop 70 therein for engagement by the hook 6 1, and the ends of the cross-member 69 may be temporarily secured in place as by means of cotter pins 71. The hook 64 preferably has an eye 72 formed thereon so that it may be swung or moved about from above, as, for example, by means 'of a string connected thereto orby means of a pole. With such arrangement the janitor, having placed a number of ash cans where they can be gotten at from above, may repair to the place where the cans are to be delivered, as the sidewalk 12, and operating the devices for connection to the cans from such distance in the manner just referred to, he may also operate the hoist from such location. The operating means for such; purpose may comprise a three-way valve 73 which may be operated by a handle 7 1. T 0 such valve the pipe 75 may deliver water from any available source of pressure, such as the city mains, the pipe 76 may communicate with an outflow, as the sewer 77, and the remaining pipe 7 8 is connected to hydraulic means for operating the valve 35. In the form shown in Figs. 1 and 6 the rod 47 for operating the valve 35 extends into contact with the flexible diaphragm 79 extending across an otherwise open bottomed dome 80, the rod 47 being preferably provided with a head or enlargement 81 for obtaining extensive bearing surface on the diaphragm 79. A spring 82 is provided for forcing the rod 17 and the valve 35 upwardly, and when water is admitted through the pipe 78 into the chamber 80, the diaphragm and rod 47 may be forced downwardly to a position such as indicated in dotted lines in Fig. 6, and it will be readily seen how the valve 35 may be operated by properly controlling the handle 7%. In the position shown in Fig. 8, the supply pipe 75 is utilized to force the diaphragm 79 and rod 47 downward, or when the handle is turned so as to bring the pipes 7 6 and 78 into communication, at the same time shutting off the supply pipe 75, the diaphragm 79 may be permitted to rise through water being discharged to the sewer, or the valve may be maintained in intermediate or neutral position by turning the handle 74 into intermediate positions.

The operation of the apparatus has been indicated in connection with its description. It will be seen that the device is simple in construction and can be readily and inexpensively maintained and operated, and that it affords a very considerable saving in time and a very considerable reduction in the necessary work of hoisting heavy objects, particularly in the removal of refuse of various sorts from the basements of buildings, such as flats, schools, ol'liee buildings and the like, and enables work of this character to be effectively performed by women or others who are incapable of performing heavy manual labor.

I claim:
