To all whom t may concern:

Be it known that I, LEWIS J. EVANS, a citizen of the United States, residing at Kirkwood, in the county of Broome and State of -New York, have invented new and useful Improvements in Elevating Devices, of which the following is a specification.

The invention relates to elevators and has for an object to provide a device for elevating articles or packages.

'l'he invention embodies, among other features, a device that is particularly adapted for use in removing the ashes and cinders from a furnace, the mentioned ashes and cinders being received in a suitable container, conveniently placed beneath the furnace to receive the ashes and cinders from the ash pit thereof, the container being mounted on a suitable carriage, forming a part of my device, and which is movable to elevate the container and remove the same from beneath the ash pit to a Yconvenient place of disposal.

ln the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specilication, in which similar characters of reference denote corresponding parts in all the views, and in which: Y

Figure 1 is a side elevation of my device showing the carriage in lowered and normal position, a wall of the well and a portion of the frame of the device having been broken away to disclose the container arranged in normal position; Fig. 2 is a vertical transverse sectional View taken on the line 2 2 in Fig. 1, looking in the direct-ion of the arrow; Fig. 3 is a side elevation of the device showing the container inl elevated position, a,

wall of the well and a portion of the supporting frame having been broken away to disclose the interior arrangement and location of the device; Fig. t is a plan view of the structure disclosed in Fig. 3, the well door being shown in open position; and Fig. 5 is a fragmentary enlarged vertical sectional view taken on the line 5-5 in Fig. 4; to disclose the locking memberv for retaining the carriage in elevated position.

Referring more particularly to the views, I disclose a well 10 formed in the ground 11,

a furnace 12 embodying an ash pit 13 being` mounted onthe surface of the ground 11 with the front portion of the ash pit 13 prosy jecting beyond a wall 14. of the well 10. The

walls of the well 10 are preferably formed of concrete and a plate 1o is preferably mounted on the ground 11 or concrete, beneath the furnace 12, the plate being arranged between the surface of the ground and theash pit 18. A tongue is struck from the plate 15 to form an opening 16 therein, the mentioned tongue being bent downwardly to extend into the well 1t) and constitute a guide plate 17, provided to guide the contents of the ash pit when the saine pass through the opening 16, arranged over the well 10. Y

Mounted on the base of the well 10 and supported by the upper ends of the Walls thereof is a rectangular supporting frame 18 and extending downwardly from an end piece 19 of the supporting frame 18 is a bar 20, bent inwardly at tlie bottom of the well l() and curved upwardly to form a track 21, the free end of the bar 20 being rigidly secured to an end piece 22 of the supporting frame 18, the mentionedv track 21 being arranged to conform to the curve described by the forward end of the carriage, where the same operates over the track, the said track being arranged centrally in the Well 10 as shown in Figs. 2 and 4.

A squared, transversely extending shaft 23 is journaled on the supporting frame 18 at points adjacent the front end of the ash pit 13, and bifurcated ends 24 of arms 25 are rigidly secured to the shaft 23 adjacent studs 2o, formed on the ends of the shaft 23, the mentioned studs 26 being mounted in the supporting frame 18 to permit of swinging the arms 25 relatively to the said frame, the lower ends'of the said arms having pivotal connection with a carriage 27 consisting of a frame 27?*` provided with a base or platform 28, said frame terminating at the forward end in ears 29 having a roller 30 journaled thereon, the said roller being operable over the track 21 as shown in Figs. 1 and 2, the mentioned arms 25 being preferably connected to the carriage 27 by passing studs 31, eX- tending laterally from the carriage, through openings in the lower ends of the mentioned arms1 the point of pivotal connection of the arms 25 with the carriage 27 beingoiset and slightly in the rear of the vertical-center of the carriage 27, so that when the carriage is elevated by advancing the same along the track 21, the carriage will, at all times,'rnain tain a horizontal position, the said vcarriage being movable to swing on the said arms 25 and to slide on the track 21, as will be -readf ily understood. A flange 27b vis formed Vintegral with the under side of the carriage frame A28 and projects outwardly. Upon this iiange the arms 25 rest, thus preventing. the forward tilting of the platform when.; the latter is supporting the-loaded ash can. An operating lever 32 is rigidly secured ill the squared shaft 23, the said operating lever being adapted 'to normally lie below-the surface of the ground l1 and movable upwardly 4into a vertical position, thus rotating the `shaft 23 and imparting a forward' swinging movementtothearms 25 which, in turn, will 'cause the carriage 27 `to vbe advanced valong the track A21, it `being V'readily understood that the arms 25 constitute a carriage frame for the carriage 27 and by means 0f which the carriage is operated over the track 21.

A container 33 is removably Ymounted upon the carriage 27, suitable guide members and 85 being rigidlyl mounted on 'the upper side of thecarria'ge 2T to aid in guiding the container 33 when'tlie same is placed upon the carriage 2'?, the mentioned-member 'being provided at the rear end of the carriage 27 lto prevent the container from being pushed or movedout of proper position on the carriage 27 so that whenV the vcarriage is in normal position the opening of the container will be immediately `beneath the opening 16 in the plate 15, with the free end ofthe guide plate 17 projecting' downwardly into proximityto thetop of the container. Now assuming that the carriage 27, having the container thereon, is in the position shown in Fig. 1, so that the contents'of the ash pit will readily pass vinto the container 33 through the opening 116, when it is desired to remove the yiilled container and replace the same by yan empty one, an upward pull is exerted on the free end of the operating lever 32, thus advancing the carriage 27 aloiigthe track`21 until thevcarriage reaches a position `substantially in alinement with the surface ofthe ground 11 as vshown in Fig. 8, the container 38 being now in aposition to be easily removed from the carriage 2?' and replaced by an empty container, after which the loperating lever 32 is returned to the position shown in Fig. 1, thus returningthe carriage 27 to normal position so that the new container will be arranged beneath the projecting end-of the ash pit, thus permitting the contents of the ash .pit to pass through the opening 16 and be -guided by the plate 17 into the container. By offsetting the point of .pivotal connection ofthe arms 25 with the carriage 2T, as men, tion'ed heretofore, the weight of the car-y riage and the weight of the container upon the carriage will be evenlyV balanced and.l

' supported yby the roller 30 and the arms `25 so that when -the carriage 27 is advanced along the track 21, the carriage will, at all t-inies, remain in horizontal position, as nientioned heretofore.

In Fig., 5 I disclose a. locking member 36, A Acomprising a bracket 37 secured to the supporting frame 1S and having mounted to swing thereon a weighted dog 38, and a footleier having pivotal connection with the dog 38 andextending upwardly. Then the carriage 27 swings upwardly one ofthe arms engages the dog 3S and, in view of the pivotal connection of the dog with thc bracket 37, the dog will permit the arm to pass upwardly beyond the dog, rafter which, when the upward pull is released on the lever 32, the arm 25 moving downwardly will be `caught and supported in locked and rigid position by the dog 3S as will be greade ily understood, it being further seen that when a downward :pressure is exerted Aon the free end of the foot lever 39, the dog 38 will be lswung upwardly -so as to disengage the same from the arm 25, thus `permitting Athe carriage 2T to move gravitationally down `on the track 21. [is shown in Fig. a, l .preferably provide a plurality of locking inembers 36 mounted on the longitudinal sides of the supporting frame. 1S to support both arms 25.

My device can be used inconneotion with various kinds of furnaces or stoves which, in their operation, produce a residue that must be vperiodically removed from the vash pit-s thereof and it will be readily apparent that my device can be used iin connection with various power plants, mills or any other places where it is desired to elevate articles or packages from one plane rto another. i

YVhen the carriage 27 is in llowered -position within the -well 10, the various parts of my device, with the exception of the foot lever 39,1will be arranged within the lwell 10 and in order to prevent anyone 'from falling into the well and to permit the operator of the furnace to properly attend to the same, I employ a closure 4() for the well '10,

lthe mentioned closure being preferably made to swing from the supporting frame 18 and movable to close the opening of the well, la slot 41 being formed in the closure l10 to receive the upper end of the foot lever 39, said foot lever being arranged to extend exteriorly of the well, as mentioned heretofore.

It will be readily seen that by offsetting the kpoints of pivotal connection of the arms -25 from the central vertical lplane of the carriage 27, in the manner mentioned lheretofore, an additional leverage is provided,

said leverage being Amaterially greater than if the points of pivotal connection of the arms with the carriage, were in the vertical. plane :of the carriage, thus greatly facilitating the operation of :advancing and elevat- Lowest ing the carriage on the track through the medium of the operating lever 32, the device being easily operable by any person of ordi nary strength and ability.

Having thus described my invention, I claim:
