.To all whom it may concern: 1 1- Be it known that I, S'rnwA nr A. MINER, subject of theKing of England, residing at Dauphin, in the Province of Manitoba, Can- 5 ada, have invented certain new and'useful Improvements in Grain-Car Doors, of which the following is a' specification.

This invention relates tograin car doors.

, The object of the invention is 'to provide a grain car door including a pluralityof superposed panels movable vertically to ele? vated position at the top ofthe car, thereby to permit the ready-removal of grain or other material from the interior of the car, 5 a A further object is to provide means for locking the door panels in elevated or inop-- erativ'e position, andmeans for releasing the panels to permit the same to return to low-.

ered position at the door receiving opening. A further object is to provide a grain car door including a rack having a' resilient guard railarranged near'fithe samefor normally preventing the panels from engaging the teeth on the rack, said guard rail being depressed by one of the panel s, thereby to permit the panels to drop engagement-with the teeth onthe rack so as to retain the panels in elevated position atthe top of the car.

.30 I A still'further object of the invention is generally to improve this class of devices soas to increase their utility, durability and efliciency.'

Further objects and advantages will appear inthe following description, it being -und erstood that various changes. in form,

proportions and. minor details of-construction may be resorted to within the scope of the appended claims.

40 For a full-understanding of the inventio and the merits thereof and also to acquire a knowledge of the details of construction and the means for efi'ecting the result, reference isto be had to the following'description and accompanying drawings, in which; Figure 1 i's a' vertical-sectional viewjof a car provided with a grain door constructed in accordance with mv invention, a portion of the casing being the position of thewinding-drum; Fig.2 is

a transverse sectional view showing the door in lowered position; Fig. 3 is a similar view showing'the door partially raised andsome of the panels locked in elevated position by engagement with theteeth on therac k, the

, auxiliary itastene'r "or h'ook. being shown in by gravityinto broken away to shownormal or releas edposition;Eigl' 4 is a hori- -zontal transverse sectional view, taken-"on the line etet'of',Fig. 1; Fig."5 isa "detail vertical sectional view showing the manner of releasing the panels from engagement with the racli;'Fig. 6 is a detail "perspective View of one 'of-the'door panels detached; 4

Fig. [Z is a detail 'vertical sectional 'view showing the auxiliary fastening device 'or 5 'hook swung laterally into engagementwith :the adjacent door panel; Fig. 8 is a side ele- "'vation of the hook detached; Fig. 9 is a side elevation of the extension lever detached. Corresponding andlike partsare referred 7 to in the -following' description and-indicatedinall the views ofthedrawings by the same-reference characters; The improved door forming the subject matterof the p'resentinvention is sho'wnin connection'with a grain car of the ordinary construction, in which 5 designates the body of the car, 6 the floor and 7 the-door posts" spaced apart to form "the door receiving opening. Arranged "within the 'car an'd 'dis-v 0 posed at the rear of the-posts 7-, are verticallydisposed guide rods 8, the upper ends of which' are extended inwardly beneath the top 9 'of the car toform upwardly -inclined extensions 10 having theirterminals 35 bolted or otherwise rigidly-secured to the top 9, as indicated at 11;,

' 'Slidablymounted in the door receiving; opening, is 'a' vertically movable do'orincluding a plurality of superposed disconnected panels 12 having their opposite longitudinal edges reinforce 'andstrengthened by" the pr'o'visi on of metallic plates 13 and their" .opposite' ends provided with terminal wear plates or clips 14:, Extending laterally-from I the oppositeends of each panel '12, are'e'yes 15 .which'receive the guide rods8-and'serve to retain'the panels in properposition when' the door is'rais'ed and-lowered. The-shanks of the eyes 15 extend through suitable open- 'ings in the adjacent metallic clips 14 and t are provided with enlarged heads 16, which latter are seated in correspondingly shaped openings formed in' the-panels so as to form panels and the adjacent eyes. v v The outer faces. of tlie panelsconipris'ing the door "bear; against an'd are guided' i'n' in effect a"swivel connection betweenthe their vertical ,movement by engagement with the inner faces of the door posts 7', while the inner'faces of said panels'bear against vertically disposed casings 17; The casi gs or E i 1,047,131 f housings: 17 extend approximately the entire height of the door and are arranged with their inner longitudinal edges overlapping the-adjacent ends of the panels 12 so as to .form'a protection for the rods'8 and eyes 4 and thus preventgrain and other material from interfering with the operation of the door. It will here be noted that the casings 1 orhousings l7,"not only form a protection for the guide rods and eyes, but, by engagement with the, ad acent-faces of the panels 12, also form guides for-the rear face of A the door, the posts 7 formingguides for the pulley 23 disposed on the opposite side of" front faceof the. door, as before stated.

Extending laterally ,from the opposite ends of thelower panel'18, are U-shaped clipsor yokes 19 having centrally disposedeyes 20 formed therein and to which are attached ropes, chains or other, flexible-con nectio'ns 21. The rope 21'on one side of the doortre'celving opening extends over a single wheeler-pulley 22and thence over a' double the do o r' receiving opening for attachment to a'windrng while the other rope or cable 21'extends over the double pulley 23-ai1d is-also attached to the drum 24, a

flange' 25' being formed on-the drum 24 in order-to separate the cables 21. The drum 24 is mounted "for rotation in suitable bear- 'ings 26 disposed within the chamber or compartment' 27- formed by the car-lining'28- and is providedwith a cylindrical portion for engagement-with, an operating lever- 29 so that by oscillating the lever 29, the drum 24 may be rotated to raise or lower the door. Pivotally mounted on the lever 29 is a pawl 30 adapted to engage a. ratchet wheel 32 car-1 .ried by the drum 24,- there being asimilar pawl 33 pivotally mounted on the car and e'ngaging'the' ratchet wheel 32 .in order to elevating the door'.. Thus it {will be seen that prevent rearward rotation of the drum when ,the pawl 30, by engagement withthe. ratchet,

4$ 'serves'.t o rotate the drum 24-when the lever 29 .'i s oscillated,"while the pawl, 33, by engagementwith the ratchet 32, serves to prevent rearward rotation of said drum. Se

cured to the pawls 30 and 33, are short chain sections 34', theiree ends ofwhichextend through an opening 35 formed in the adjacent'do'ori-post 7 and are provided with ter- ;minal rings 36 adapted to engage a hook- I or similar fastening device37 secured to the 5:5-

door post for the purpose of holding the pawls 30 and 33 out of engagement with the ratchet wheel 32 when it IS desired to lower f the panels constituting the door.- Dlsposed in spaced relation to the top of the-car are spaced inclined rack bars 39-having their inner. ends secured to the casings 17 and their .outerends' fastened by the bolts 11 to .',the,.top. of the car,- as best shown in Fig. '3} of the drawings; The rack bars 39- are pro-I vided with spa ed eeth or pockets 40 adapted to receive the adj acent longitudinal edges or corners ofthe panels 12 for retaining said panels in elevated position, there being suit-' able arcuate guide bars 41 secured to the side and top of the car in spaced relation to the-racks 39 for the purpose of guiding the panels 12 to the rack bar when the grain car door is elevated. Arranged near the inner longitudinal edge of each rack bar 39 and preferably disposed in a plane above said rack bars, are depressible guard rails 42,

preferably in the form of resilient rods, the

inner ends of which extend beyond the fastening device or bolt 11 and are retained in position on the top of the car by suitable anchoring members 43. The depressible' guard rails 42 are inclined upwardly so that the space between .the rear ends of the guard rails and the top of the car is less than the space between the forward ends of the guard railsand the top of the car so that when-the first panel constituting the door, is moved to elevated position near the fixed end of the extensionsflO .it will depress the guard rails 42 and thus permitthe adjacent panels 12 to enter the pockets 4.0 and in which position they will beeffectually retainediuntil released by the operator. Thus it will be seen that by rotating the operating lever 29, the chains or cables 21 will ;X1l3 3 longi-- tudinal pull on the lower panel 18 and elevate all of the-panels so as to permit access to the interior of'the car. -As the top panel approaches the inner or fixed. ends of the extensions 10, said top panel will be wedged against the top of the car thus depressing the guard rail/l2 and permitting the adjacent panels 12 to drop by gravity intothe pockets 40, the swivelconnection between the shown in Fig. 3 of the drawings.

Secured to the transverse beam-"44L of the door receiv ng opening, is a suspension loop or eye 45 adapted to receive a removable extension lever or bar 4:6, the function of which is to elevate the panels 12 and thus disengage thelatter from the pockets or teeth 40 of the rack bars so as to permit sa d panels to be moved to any desired height above the floor of the car. The lever or bar 46 is pro vided with a terminal "socket 47 adapted to receive the reduced end of the operating lever' 29, the'levers 29and 46 being housed withinia suitable recess 48 when ,not'in use,

einedwithin said recess by clip- 48 i-rain 'marks'or graduationsx49 may be formed on the car or on the panels comprising-the door so that if it is desired toload' a car with wheat, it will not be necessary to lower all of the planks or panels, but simplv to drop thepanels-until the panel marked Wheat is lowered, and in'this' way, allow. the attendants to crawl in and out of the car, as may be desired. l 3

-I-t will here be noted that thejpanels com- .prisin'g'the door, are independently mounted for both vertical and tiltin movement on the guidero'ds 8 and extensions 10, so'tha-t any number of panels' may belowered, while .5 the remaining panels arelocked in' inoperative position at the top of the'oar, said panels being released by the actuatinglever- 46, in the manner before stated. v v

VVhenit is desired to elevate only a few of the door panels, some means 'must be provided for holding said panels in elevated position when the pawlsand 33 ar e released, as the guardrail 42 is only depressed to permit thepanels' to. enter the pockets of the rack il'when the upper panel of the-door bears against the top. ofthe can. In order to effect this'result an auxiliary fastening de-' vice or hook A9 is' suspended from clip or bracket secured to. the uppersill of the car door, said hook being provided with" a curved slot 51 adapted to receive the pivot pin 52,j there .being notches, or recesses 53 communicating with the opposite ends of the slot 51 for the reception of the pivot Y 7 pin 52. Thus it will-be seen that when the hook 49: is moved "with the lever 46 in one direction, the' pivot pin will enter one of the notches or recesses 53 and cause the active end of the hook to. engage the adjacent door panel and support the same in elevated position as'bestoshown in Fig. 7 of the drawing's, and when. said hook is tilted in the opposite direction, the pivot pin will enter the othernrecess 53 and hold the act ve end of the hook -out of the path of the panels "50 as to allow said panels to drop to the bottom of the .door receiving openln'g. It willof coursebe unde'rstoodthat when some of the panels are supported inelevated position either'by therack 40 or hook 4:9 the-remaining panels may be lowered -to the bottom of the door opening by releasing the pawls 30 and 33. '-It'-wi11 here be noted that the guard-rails 42 preventtheglower longitudinal edges of the panels from riding'over the teeth of the racks 39 when-the panels are moved to. ele. vated position, th'isnot only to prevent ex cessive wear on said panels, but also to prevent undue strain on or vibration oi said racks which would have atendency to loosen the fastening devices thereof and Havingi thus described the invention, what is claime as new is:
