WILFRED ALMON HARE, 0F TORONTO, ONTARIO, CANADA, ASSIGNOR TO THE STANDARD ENGINEERING COMPANY, OF TORONTO, CANADA.

HOIST.

Specification of Letters Patent.

Patented July 5, 1910.

To all whom it may concern:

Be it known that I, WILFRED ALMoN HARE, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Hoists, of which the following is a specification.

The invention relates to improvements in hoists, as described in the following specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts, whereby members for supporting the front end of the car and pivotally supported from the frame are operated to swing outwardly by the operation of the hoist mechanism.

The objects of the invention are, to facilitate the removal of ashes from railway locomotives and the loading of same into ash cars, to provide an elevated structure for raising the ash car which will not interfere with the passage of another car or locomotive past the hoist, and to devise a neat, strong and simple form of hoist which may be used for loading ashes, coal or other loose materials.

In the drawings, Figure 1 is a side elevation of the hoist showing the car in its unloading position in full lines and in its lowermost position in dotted lines. Fig. 2 is a front elevation of the device, the flange of the car being partly broken away. Fig. 3 is an enlarged perspective detail showing the means for operating the extension trackway. Fig. 4 is a sectional detail showing the stop for limiting the movement of the extension track-way.

Like numerals of reference indicate corresponding parts in each figure.

Referrin to the drawings, 1 is the main frame of the hoist formed of the side up rights 2 rigidly supported at the to and bottom and braced toward the bottom by the cross braces 3.

4 is a cross beam extending between the uprights 2 intermediate of their height.

5 are the rails forming a permanent trackway for the ash car secured at their ends 6 to the upper side of the cross beam 4;, the extremities of said rails projecting outwardly slightly beyond said cross beam. The ralls 5 are curved downwardly from the inner side of the cross beam 4 and extend angularly downward to the pit 7 arranged beneath the rails 8 on which the locomotive, discharging its ashes, runs. The said rails 5 are curved outwardly toward the lower end to bring the car beneath the opening 9 between the rails 8. The rails 5 are braced from the uprights 2 by the struts 10.

11 are short lengths of rail rigidly secured to the outside of the rails 5 and extending angularly upward beyond the curved portions of the said rails 5 and rigidly supported from the main frame, the upper ends 12 of said-rails being bent at an angle upward from the main portion. 7

13 is the ash car formed of a long scoop shape having the double flanged rear wheels 14 and the single flanged front wheels 15 journaled on suitable axles.

16 is a bail pivotally secured to the outer ends of the rear axle of the car 13.

17 is a rigid boom structure extending outwardly from the front side of the frame 1 and carrying the grooved sheave 18 in suitable journals at the outer end thereof.

19 is a sheave suitably supported from the frame 1 in angular arrangement therewith and below the sheave 18.

20 is a double sheave journaled in suitable bearings in the side extension frame 21 secured to one side of the frame 1.

22 is an air cylinder secured between the extension frame 21 and the main frame 1 at the bottom thereof having the piston rod 23 extending from its upper end and supporting a double sheave '24:, said piston rod having a suitable piston secured to its opposite end.

25 is a grooved roller journaled on the outwardly extending end of the shaft 26 supporting the double sheave 24:.

27 is a flexible cable, at one end secured to the bail 16 of the ash car 13 and extend ing around the sheave 18 under the sheave 19 and around the

double sheaves

20 and 24 and secured at its other end to the frame.

The operation of the piston of the air cylinder 22, through the cable 27, operates the car 13 to be raised or lowered on its tracks. In the upward travel of the car the front wheels and the inner flanges of the rear wheels travel on the, rails 5, and the forward end of the car follows the upper curve of the said rails 5 leading to the ends 6. The rear wheels of the car having the flanges extending outwardly beyond the rails engage the rails 11 and rise upwardly past thecurved upperportionof said rails 55, the bail 16 swing ngfreely on the axle as. the car changes its position in relation to the angle of inclination of therails 5.

. "32 is a shaft rigidly secured in the lugs 29 andi and extending therebetween.

"33 is a beveled gear segment haVlIl%' tl16 t 32. 351s an arm extending from the sleeve 34 at the opposite end to the segment33 and having. a socket 36 formed on its outer y :1 37 is a bentarim rigidly secured in the sgcket'36. of the arm andadapted toengage the'g rooved roller25 in its downward movement.

.38-is a shaft j 'ournaled in the journal bearing 31 atone end and in the bearings 39 supportedfrom thecross beam 4. 4Q is beveled, gear se 'ment fixedly secured to one end of the sha t 38 and meshing with the segment 33.-

, "41 are the extension rails having the hub portions 42 fixedly secured to the shaft 38,

saidhub portions havingthe stops 43 projecting from one end thereof,said stops being adapted to engage the corresponding stop'p'ortions 44 extending from the ends of the journal bearings 39. g

45,.is a lever fixedly secured to the shaft 38, at the opposite end to the segment .40 and having the counter balance weight 46 adjustably secured thereto, The counter balance ,is arranged to normally hold the extension rails-in the upright position shown in dottedlinesQin Fig. 1 and when said rails are in a this position the arm 37 is swung through the inter-meshing gear segments to its upper 7 position.

' In theoperation of this device the locomo tive is brought overthe. ash pit and the ashes and cinderslfro-m the fire box are discharged into the car 13. The air cylinder is then operated todraw downwardly on the cable, ,pulling- ,the car upwardly over the rails As the car approaches the curved upper end of the rails5'the grooved roller 25' engages the arm swinging saidarm downwardly and. consequently. swinging the gear segment '33 on the shaft 32; The swinging. of the segment 33 turns the shaft 38 in its bearings through the segment. 40, ele

jva-ting :the .icounterTbalance weight and throwing the extension rails 41 downwardly totheir horizontal-position, the stops on the hubs of said extensionma'ils engaging'the The roller 25 con inu i'en m tw hh tr i t p. tion of the bent-arm 37 during the remainder 'of its downward travel, thus holding the ex- 7 wheels of the car 13 pass over the curved portion of the rails 5 and continue onto the extension rails 41. The extension flanges of the rear wheels of the car engage the rails 11 and traveling upwardly along said rails elevate the back end of the car, thus holding the said car so that the back Iendis elevated to cause the contents to slide out into the ash car or other receptacle brought underneath the said extension rails. The return movement of the air piston allows the rear end of the car to drop and as the. front wheels withdraw from the extension rails the grooved roller 25 passes the shoulder on the arm '37 and allows the said extension I railsto swing upwardly on their pivots, the counterbalance weight returning the parts to normal.

W A device such as described maybe placed beside arailwa-ytrack and utilized for the unloadingof loose materials of any kind from one vehicle and loading it upon another and does not-in any wayinterfere with trafiic on other lines as no part of the device extends over the track except when the conveyer car is actually discharging its load. The extensionrails, provided to carry the car a sufficient distance outwardly to discharge" its load, return immediately to their normal position after discharging its load. f The preferred form of construction is herein shown and described but it must be understood that many of the parts may be changed considerably without departing from the spirit of the invention.
