JOHN M. BARNEY, OF NEW YORK, N. Y.

ASH AND REFUSE HOISTING DEVICE.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed March 4, 1918. Seria1 No. 220,357.

To all whom it may concern Be it known that I, JOHN M. BARNEY, a

citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Ash and Refuse Hoisting Devices, of which the following is a specification.

My present invention relates to an ash and refuse hoisting device, and particularly to a structure of this character which can be installed in a basement or ash pit of an apartment, office building, or the like, and which can be .used. in elevating cans or containers to a road or street level and then to raise the same to a height that the contents can be dumped into a wagon in which the ashes or refuse are to be carted away.

An object of my invention is to provide a device which can be installed in any basement or ash pit and which can be connected to be operated by a fluid pressure, which pressure can be obtained through connection to a water pipe, a steam boiler as for instance a heating boiler, or to other sources of supply of fluid under pressure.

A further object resides in providing means by which the main supporting or crane structure is retained in an elevated position and in such a relation that can or receptacle lifting means associated therewith can be used to hoist a number of receptacles from the basement or pit where the device is installed:

Another object lies in arranging fluid control means whereby both-the movement and operation of the main supporting structure and of the receptacle hoisting mechanismcan be controlled from the pit or from the street level, 'and in providing in conjunction with the-main structure means by which the same is given a partial turn to swing the crane arm from which the receptacle is hoisted and to thus carry the can or receptacle out and over a wagon to which the contents is to be loaded,

A still further object is to provide in conjunction with the moving parts, means by which the pit or basement doors are moved to an open position, while at the same time retaining and guard means carried by the doors is brought into position 'to retain the doors in an open relation and to dispose a fence around the pit opening.

Yet another object is to arrange with thev doors, an audible alarm means to be rendered active by opening and closing of the doors and to thus give warning to pedestrians or other passersby.

Further objects of my invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawings:

Figure l is a view taken in vertical section into a pit or basement and illustrating the preferred embodiment of my invention installed therein and with the parts in the raised or operative position.

Fig. 10 is a detail sectional view showing a cam arrangement adapted toimpart a quarter turn swinging movement to the main elevating structure when the same is brought to the upper extreme of elevation to thus swing the crane arm thereof away from the pit or basement opening.

Fig. 11 is a detail view of an electrical contact structure which can be installed in conjunction with the pit or basement doors to cause energization of an electrical circuit in which an audible alarm device is installed and to thus give warning of opening and closing of the doors,

. Fig. 12 is a sectional View showing the pit or basement doors closed and illustrating the preferred embodiment of door openmomeans.

Fig. 13 is a view similar to Fig. 12 but illustrating the doors in the open relation.

Fig. 14 is a sectional view substantially after the manner of Fig. 13 and showing a modified construction of door opening means.

In the drawings, where similar characters refer to similar parts throughout the views, A designates a sidewalk or roof covering for a basement or pit, one of the walls of which is shown at B, and this walk or roof has an opening C therein through which access is had to the basement or pit. As in disclosure in Fig. 2, it is preferable that the opening C be disposed adjacent a curb 1 which bounds a roadway or street D, and when this arrangement is observed a wagon or cart E can be drawn up closely adjacent the opening so that cans or receptacles of ashes or refuse as hoisted through the opening can be readily loaded bodily thereinto or can have their contents dumped.

.In each of the embodiments of the invention as disclosed in the drawings, the principle and method of operation is substantially the same, the principal purpose in disclosing the several forms being to illustrate structures which might be used by being installed in pits, basements, or the like, of different heights and where different conditions are encountered. In the preferred embodiment, as illustrated in Fig. 1, a supporting bracket F is shown as secured to fixed and rigid parts of the pit or basement construction, and a supporting sleeve G is mounted in conjunction with the supporting bracket. A crane upright H is slidably mounted through the sleeve G, and at its upper end has a crane arm I which is fixed thereon and Which extends laterally. In this adaptation, the raising of the crane upright H is accomplished through the use of a cylinder J which is located substantially vertically in line with the line of movement of the member H and which is rigidly fixed upon the fioor of the pit or basement by the use of the base flange 2, a piston K being mounted within the cylinder J to have reciprocatory movement throughout the length thereof. In the present adaptation, the crane upright H is made tubular, and fits telescopically over a supporting upright 3 which extends from the upper end of the cylinder J, and it will of course be understood that the member H slides upon this supporting upright 3 and through the supporting sleeve G.

A shaft L is revolubly mounted in suitable bearings provided on the supporting sleeve G to turn upon a horizontal axis, and this shaft, has large and small cable drums 6 is connected on the free end of the cable 4.

and the cable is in fact made of such length that when fluid is supplied to cylinder J to cause the piston K to move downwardly therein and drawing tension is thus exerted upon the cable 4:, this cable will be taken in to bring the counter-weight 6 to bear beneath the bracket arm 5 and then the bracket arm will be carried up to cause the crane upright H to be led upwardly through the supporting sleeve G. It will of course be understood that as lon as the fluid pressure within the cylinder is retained and the piston K is maintained substantially in the position shown by the dotted lines of Fig. 1, the crane upright H will be held in the raised position, but that the upright will be retained in this position without maintenance of the pressure within the cylinder,

it is preferable that a spring latch means as shown in Fig. 8 or a gravity latch means as illustrated in Fig. 9 of the drawings be employed.

With the latch device as illustrated in Fig. 8, the crane upright H is slotted through as shown at 7, and a spring member 8 is secured in place to have the free end thereof project within this slotted opening 7, a lug 9 being carried by the free end of the spring member to extend beyond the outer wall of the upright H. When the crane upright H has been carried in its upward movement to such a position that the lug 9 clears the supporting sleeve G, the spring 8 will cause this lug to be extended substantially after the manner shown in Fig. 8 and in this relation of the parts, the

lug will catch upon the upper end of the supporting sleeve or upon the supporting bracket F and in consequence the crane upright H will be retained in the elevated position until the lug 9 is moved back against the bearing pressure of the spring 8. With the gravity latch device as shown in Fig. 9, the links 10 and 11 are given swinging mounting on the supporting sleeve G, upon an extension of the su porting bracket F, or at some other suitab e point so that the free ends thereof will swing below the position assumed by the bracket member 5 when the crane upright H has been raised to the position shown in Fig. 1, and at their lower ends these links 10 and 11 have the rollers 12 and 13 mounted to be disposed on their inner sides. A handle 14 is connected with the free ends of the links 10 and 11 and is.

offset angularly to one side, substantiallyas shown in Fig. 3, the rest of the parts being such that as the crane upright H occupies the lowest position, the rollers 12'and 13 will bear thereagainst and in consequence the links 10 and 11 will be held swung to one side, but as the crane upright is raised to the position shown in Fig. 1, the weight of the handle 14 will be suflicient that the links 10 and 11 will be swung around their mounting and the rollers 12 and 13 will be carried to catch beneath the bracket member 5. When the rollers 12 and 13 are caught beneath the member 5, the crane upright will be maintained in the raised position until the links 10 and 11 are swung to move the rollers from the position of engagement.

As the piston K is to be moved within the cylinder J through the supply of fluid under pressure thereto and as the movement and operation of the parts is to be controlled either from within the pit or basement or from the sidewalk level, it is essential that a suitable piping system be arranged from a source of supply of fluid under pressure to the cylinder J, and that valves be entered into this piping system to allow for opening and closing of the nected with theupper end of the cylinder" same by a party outside or within the pit or basement. A main fluidsupply pipe15 which has a cutoff valve 16 therein is con- J through a pipe 17, and this pipe 17 has a valve 18 therein which might well be of the three way type. A valve 19, which is also preferably of the three way type, is carried y the crane arm 1, and a flexible tube 20 is led from the fluid supply pipe 15 to this valve 19, a second tube 21 being led from the valve to connect with a pipe 22 which is joined in the pipe 17 between the cylinder J and the valve 18. Assuming that the cutoff valve 16 in the fluid supply pipe 15 is open, the fluid under pressure will be supplied into the pipe 17 and the tube 2011p to the three way valves 18 and 19 respectively, and if one of these valves be set to establish connection to that length of the pipe 17 which connects with the upper end of the cylinder J, fluid will be supplied to the cylinder to cause the piston K to travel downwardly therein, and then when it is desired to release the pressure within the cylinder so that the piston K will return to the upper end of the cylinder through the pulling strain exerted upon the cable 4 by the counterweight 6, either valve 18 or valve 19 will be opened to establish communication from the cylinder J to the atmosphere or to a suitable exhaust pipe and thus the pressure is relieved within the cylinder and' free return movement of the piston as allowed.

To guard against too quick movement of the piston K in itsdownstroke when fluid is supplied to the upper end of the cylinder J, it is'preferable that a liquid damper de-j vice be installed, and as is shown in Fig. 1, a pipe 23'is connected'with the lower end of the cylinder J and is then extended to a tank 24 which is supported at a height corresponding substantially to the highest point .of movement of the piston K. A valve 25 is connected in the pipe 23, and assuming that the tank 21 is filled with water, oil, or other suitable liquid, the rate of flow of which through the pipe 23 can be controlled by manipulation of the valve 25, it will be seen that the speed with which the piston K is moved in its downstroke can be very accurately controlled and regulated.

The crane arm I has cable wheels 26 and 27 mounted revolubly therein, and a cable 28 is carried over these cable wheels, that end hanging over the wheel 27 is provided with a hook 29, and the remaining end being extended down substantially parallel with the crane upright H and carried around the cable drum M, to which this .end of the cable is anchored.

The structure as described will be installed for use substantially as is illustrated in Fig. 1, and assuming that the valves 18 and 19 are closed and have the vents thereof open to exhaust the fluid contents in the upper part of the cylinder J, it will be of course appreciated thatthe crane upright H will be in a lowered position in which the crane arm I is below the top level of the walk or cover A of the pit or basement, and both cables 4 and 28 will have the free ends around the cable drum N about which it is given a double turn, and in consequence this drum and'shaft L will be revolved.

The revoluble movement of the shaft L is transmitted to the cable drum M, and consequently the cable 28 is also taken in to hoist the can or. receptacle caught by the hook 29. When the cable 4 has been taken in sufliciently that the counter-weight 6 comes to bearing engagement against the lower side of the bracket arm 5, the hook 29 will have been raised to substantially a position illustrated, and through the fact that a direct pull is established against the bracket member 5, the crane upright H will be given upward sliding movement through the sleeve G and will in consequence be raised to the position illustrated in Fig. 1 where the latch member will be free to move to a position to become operative in retain ing the crane upright in this raised position. Now if the open valve be closed and be brought to a position to reestablish an exhaust connection from the cylinder through the vent to the atmosphere, the crane upright H will be still retained in the elevated'or extended position, but through the force exerted by the counter-weight 6, the piston K will be raised within the cylinder J and the cable 4 will be drawn around the cable drum N. This movement of the cable drum N will cause the drum- M to be revolved and in consequence the cable is unwound therefrom and is free to run over the wheels 26 and 27 so that the hook 29 is lowered to a position to have other cans or receptacles attached thereto. Now upon again opening one of the valves to supply fluid under pressure to the cylinder J, the piston K will be again carried toward the bottom of the cylinder J and through the I taking up of the cable 4, the cable drum will be again revolved and the cable 28 will be wound in to raise the can or receptacle attached thereto.

In the embodiment of the invention as shown in Fig. 2 of the drawings, the con struction and arrangement of the parts is only slightly different and the operation is accomplished in substantially the same way as with the parts illustratedin Fig. 1.

In this adaptation, the supporting upright 3 is shown as extending entirely down through the base portion 2, and the cylinder J, is mounted substantially parallel with and at one side of said supporting upright 3 the mounting of the cylinder being such that it is disposed at the top of the pit or basement. A cross head 30 is connected with the supporting upright 3 adjacent the lower end thereof and a tubular upright 31 is supported on this crosshead 30 at its lower end and at its upper end has the cylinder J alined therewith, then tubular member 31 thus acting to support the cylinder. A cable wheel 32 is mounted in suitable bearings provided on the cross-head 30 and the cable 4: is carried down through the supporting upright 3, around the cable wheel 32, and up through the tubular upright 31 to connect with the piston rod of the piston K. It will of course be appreciated that the fluid supply pipe must be connected with the lower end of the cylinder J so that the piston K will be carried upwardly therein, and that the liquid damper pipe has connection with the upper end of the cylinder, but aside from this the remaining parts of the structure are substantially as shown in Fig. l and are arranged to operate in substantially the same way, in view of which fact similar reference characters have been applied thereto.

With the modification as illustrated in Figs. 3 and. 4, the relative arrangement of the crane upright and the cylinder is substantially the same as shown in Fig. 2, but some departures are made in the manner of arranging the cable drums and of attaching and extending the cables. In this adaptation, the supporting sleeve G is mounted in conjunction with the bracket F and further I support is given to the sleeve G by a bracket 33 which is secured to the wall of the basement or pit, and is braced therefrom. The cylinder J is also securely fastened to the wall of the basement or it, and the tubular support is dispensed with, but aside from this, the crane upright H has sliding mounting through the sleeve G in the same manner and the piston K moves within the cylinder J 2 substantially as described in conunction with the showing of-Fig. 2. A base portion 34 is securely anchored to the floor of the basement or pit and has bearing standards 35 and 36 carried thereby, a drum shaft 37 being journaled in the bearing standards. A large drum 38, an intermediate drum 39, and a small drum 40, are all secured to be held upon the drum shaft 37 against turning movement, and it is preferable that the drum 40 be located vertically beneath the extending end of the piston rod by which the piston K is carried while the drum 38 is located centrally beneath the supporting sleeve G In this ada tation, the shaft L, together with the cab e drums M and N, is dispensed with, and a cable wheel 41 is revolubly mounted on the bracket 33. The cable 28 is led over the cable wheels 27 and 26, and then down through the tubular crane upright H, and on down to the cable drum 38 with which the free end is fixedly connected, and a cable 42 which is connected with the piston rod moved by the piston K is led over and anchored upon the cable drum 40 so that as the piston K is moved within the cylinder J the drum 40 will be turned I and each of the remaining drums will be correspondingly revolved. A cable 43 is anchored on the intermediate drum and is car-v ried over the cable wheeel 41, the free end being connected with a counter-weight 6. Then fluid under pressure is supplied to the cylinder J the piston K is given upward movement thereto and in consequence the,

.modified form of the structure, which modi-' fied construction partakes somewhat of the characteristics of the form illustrated 1n Fig. 2, this structure however, belngadapted for use in a basement or pit havin a relatively substantially at right angles to-the, line. of-

low roof or ceiling covering. supporting l5 sleeve G is carried from a supporting bracket F and the crane upright H is slidably mounted through the supporting sleeve, a tubulars'tandard 44 being mounted by the base plate 45 to be supported from I at the upper end thereof and cable wheels are carried by the crane-arm as 1s descr bed ment. The sleeve Gr carries a member L which correspondssubstantially to the shaft' and the piston rod 47 extending from this cylinder has a cable wheel 48 carried at the outer end thereof. A supporting bracket member 49 is secured on'the tubular upright 44 adjacent the base 45, anda cable wheel 50 is carried by this bracket member in line with the cable wheel 48, a cable wheel 51 being mounted in conjunction with the supporting sleeve G and being alined substantially vertically above thecable wheel Y70, and it of course being understood that these several wheels are lined up with the cable drum N An anchor bolt 7 2 is connected in the floor of the pit or basement adjacent the base member 45, and a cable 53 is connected with the anchor bolt and is then led over the cable wheel 48, under cable wheel 50, up through the tubular standard 44, around cable wheel 51, about the cable drum N and then down alongside the crane upright H and through an opening in the bracket portion 5, below which the counterweight 6 is attached to the free end of the cable. By thearrangement in the manner as set forth, when fluid is supplied to the cylinder J through piping connections and valves which might be substantially identical with similar parts as shown in the remaining figures of the drawings, the piston rod 47 will be drawn in to the cylinder and in sum the floor of thebasement-or pit, and being. received telescopically within the crane up-.'

right H This upright has the'cranearm in connection with the preferred emboditially parallel with the crane upright H the fluid pressure within thecylinder J will sequence the cable wheel 48 willbe thus accomplishing a double pull upon the cable 53 due to the fact that one end thereof 1 is permanently attached to the anchor bolt 52. Bythis arrangement of .the arts it is possible to use a cylinder in whic the pis-. 4

7 ton has a comparatively short .stroke as the;

ratio movement imparted to thecrane-u right is as two to one with respect of t e. movement of the piston within the cylinder J A able wheel 54 is mounted in conjunction with the bracket member49 onan axis the ashes or refuse is contained.

As the arrangement of the parts is such that a considerable length of cable must carried over each of thecable drums N and M and as the most efiicient action is'ac complished when the cable exerts a straightfand direct pull, it is preferable that pro- 96 vision'be made for shifting of the cable drums as the cables are wound therearound. With this purpose in View, I provide external screw-threads on the member L and internally screw-thread the cable drums M and N together with the hub 46 by which the same are joined, the pitch of the thread being such that the endwise travel of the drums upon the shaft member L will be substantially relatively equalized with the length of the cable drums covered by each turn of the cable thereabout, and in this way the cables will at all times have tension exerted thereon in direct line to thus accomplish the most efiicient hoisting action. It will of course be understoodthat. when the crane uprighthas been'raised. to" its up; permost position and has been; caught tozbe retained by the latch portion,"exhaiistionof leave ,the parts free so that the counterweight 6 will draw the cable 53 around the drum' N and the several cable wheels to I again extend the piston rod- 47,- and'atthe same time the cable 55 will be unreeled and the hook 56 will be loweredfor'the raising of the cans or receptacles subsequentito the one initially hoisted.

It'will of course be understood that the :ranefupright will in each instance be free to have turning movement within the supporting sleeve, when the upright has been raised to the extended position, so that at least substantially a quarter turn can be giveii thereto 'to swing set or extend the 180 crane arm from which the cans or receptacles will be carried and to thus dispose thecans or receptacles over a cart or wagon drawn up alongside of the opening to the basement or pit, and while this turning of the crane upright might be manually accomplished after the upright has been raised to its completely elevated position and is caughtto be supported by the latch structure, and in fact the rollers 12 and 13 of the structure as shown in Fig. 9 will act as thrust bearings in this turning movement, it is perhaps desirable that provision be made for accomplishment of this turning movement through mechanical means. While the crane upright might be turned through the use of any well known or suitable means, the structure as disclosed in Fig. 10 is one which can be installed with the hoisting structure as described and which will operate eficiently. As here shown, the supporting sleeve 56 has a slot or groove 57 prov1ded on the inner wall thereof and this slot or groove is made cam-shaped so that from its lower to its upper end it takes substantially a quarter-turn around the bore of'the sleeve, and then at the upper end a straight branch 58 is provided. The crane upright has a pin or bearing roller 59 carried thereby to be received within the slot or groove 57, and as this pin or roller 59 is disposed adjacent the lower end of the crane upright, it will not be carried into the groove 57 until the crane arm has cleared the sidewalk orcover of the pit or basement, and then through following the groove 57, the pin or roller 59 will impart a quarter turn to the crane upright in consequence of which the crane arm will be swung out to dispose a can or receptacle carried thereby substantially as is shown in Fig. 2, where it can be readily dumped or loaded into a cart or receptacle. Provision of the straight branch 58 as an extension of the groove 57 permits turning of the crane upright manually when the same has been caught to be supported by the latchportion, but it will of course beunderstood that when the crane upright is to be lowered, it must be swung to such a position that the pin or roller 59 will follow the curve of the groove 57, and with this purpose in view ill 1S perhaps desirable that the lowest side of the straight extension 58 be sloped as indicated at 60, and with this arrangement it will of course be understood that the pin or roller 59 will be guided into the groove 57 and as the crane upright is lowered will cause the same to be turned so that the crane arm Will be brought to a relation to pass through the opening in the sidewalk or cover A.

As is indicated in several main views'and as particularly shown in Figs. 12, 13 and 14, the doors 0 andP are provided to close the pit or basement opening 0, and in order that pedestrians or other passersby may be trated contact means which might be embraced in an electric bell ringing circuit and installed in conjunctionwith the doors to cause the circuit and consequently the bell to be energized when the doors are being i opened; The door 0 has a link 61 connected therewith and this link is in turn connected at its free end with a block 62 mounted to travel in a trackway or guide 63, which part will be hereinafter more fully described. The block 62 has a spring contact finger 6& carried thereby and this contact finger or member is connected in one of the wires of the circuit embracing the alarm or signal device. A spring contact bar. 65, which has the ends thereof ofi'set, is mounted upon the guideway portion 63 and insulated therefrom, the disposition of this contact bar being such that the spring contact finger 64 carried by the block 62 clears the same at the offset end but will engage with the main body portion as the block 62 is moved through opening of the door 0. It will of course be appreciated that the contact bar 65 is connected with an opposite terminal in the signal circuit, and when the parts are in the relation shown in Fig. 11-, where the spring contact finger 64: is clear of-the contact bar 65,the"circuit connection will not be established, but as the contact finger 64 comes into bearing engagement with the bar 65, the circuit will be completed and in consequence the signal 'or alarm will be rendered operative.

With this third embodiment of the door opening means as shown in Figs. 12 and 13, the track or guideway 63 is mounted substantially centrally between the hinged connections of the doors 0 and P, and is so disposed that the block 62 has sliding movement in a vertical path. The link 61 which is connected from the door 0 to the block 62, so mounting this block that as the door O is opened this block is raised whereas upon closing of the door the block is lowered, and by connecting the link 66 from this block 62 to the door P, corresponding movement will be imparted to this last mentioned door and thus as the door 0 is either opened or closed the ,door P will be likewise moved. To provide for automatic opening of the doors when the crane upright is raised, the friction roller 67 is mounted on the head thereof and a cam 69 is provided on the other side of the door 0 to be engaged by the friction roller in such a manner that as the crane upright is extended upwardly the bearing engagement of the friction'roller upon the cam 69 will cause the door 0, and consequently the door P, to be moved to their full open position. As has been previously stated, it is desirable that guard means be provided on one or both sides :of the opening C, and in the present instance this guard means is illustrated as embracing the arms and 71. carried by the underside of the doors 0 and P and made of such length that when the doors are opened they will overlap. The arm 71 carries a relatively short pin 72 which springs into an opening 7 2' formed in the arm 70 near its outer end,.

when the doors 0 and P are completely open, to lock the arms against independent pivotal movement and to maintain the doors 0 and P in the open position.

. VVit-h the structure illustrated in Fig. 12, the doors 0' and P are hinged to close over the opening C in substantially the same manner as heretofore described, the guide or trackway 65' is mounted substantially between the doors and the block 62 has vertical sliding movement therein. The link 61' is connected at one end with the door 0 and by the upper end of the link 73 is passed through the slotted openings of these cross and pivotally mounted arms 74- and 7, 5, the

arrangement of the parts being such that as the door 0' is raised and the block 62 is consequently moved upwardly through the connection of the link 61', the link 73 will be moved vertically upwardly and through the connection of the pin 7 6 through the slotted openings of the arms 74 and 75, these arms will be swung up to substantially the position illustrated in Fig. 14 to dispose a guard structure across outside of the opening C, and to open the door P.

As the description of the preferred and modified forms of the invention has been carried forward, a statement of the use and operation of the various structures has been embodied in these forms, and it is therefore not thought that recapitulation need here be indulged in, but attention might be called to the fact that changes in details may be made without departing from the spirit and scope of-my invention; but
