snafu-noon.
To all iii/wm il?! may c( .,cern:
Be it known that I, PETER A. AURNESS, of lllinneapolis, Hennepin county, Minnesota, have invented certain new and useful lm- ]Vn'oven'ients in Grain'Doors, of which the following is a specification.
This invention relates to grain doors for freight cars and the object of the invention is to provide a door of simple compact construction and one which can he easily operated for the purpose ot adapting the ear for use in hauling grain or merchandise.
A further object is to provide a grain door for freight cars which attords ready means for opening the ear and whereby the actual force required to lit`t| the door will be proportional to the number of sections, two or more, en'iployetl, less than the torce required to litt the door it it should he made in one continuous section.
A further object is to provide a door having grain tight joints and one which when not in use can be eoinpaetly collapsed or folded to occupy a recess in the wall of the car.
The invention consists generally in various onstructions and combinations, all as hereinafter described and particularly point ed out .in the claims.
ln thel accompanying drawings, forming part of this specilicatioin. Figure l is a lon gitudinal vertical sectional view of a portion ot the freight car with my invention applied thereto. Fig. 2 is an outside view of the grain door illustrating it in its closed position. Fig. 3 is a detail sectional view on the liney-y of Fig.
Fig. Ll is a vertical sectional view on the line :if-:e ot' ltig. 2. llig. 5 is a sectional view illustrating the door in its folded and inoperative position. Fig. (3 is a view of the outside ot the door illustrating a modified nieans for raising it. Fig. 7 is a sectioiial view illustrating a. modified construction of the door. Fig. S is another modilication showing a` telescoping forni ot door. Fig. 9 is a detail view looking at one side of the torni of door shown in Fig. S.
ln the drawing, 2 represents a freight car having the usual door opening 3. On each side o" the door opening vertical guideways are provided consisting' of grooves fl, 5 and 6, that are arranged parallel with one another and adapted to receive and guide the. door sections 7, 8 and 9 that have their ends itted Within said grooves and their contig Sp eccation of Letters Patent. Application filed Februarly 27, 1908.

nous edges lapping by one another and adapted to slide one upon another to ei;-
pand or collapse the door. The sections are preferably held in their proper relative position 'by interlocking' devices consisting-ot recesses l0 formed in the surface of one section and plates 11 arranged to lap over said recesses with spaces formed hetween the` contiguous edges of the plates in which the shank of a T-shaped plate 12 secured on the contiguousI door section.
adapted to slide. The door sections are thus held together hut are allowed to slide up and dowi in their guideways hut. their edges will he held against separation and the escape olilthe grain.
At the bottom oit.` the doorway on each side l provide anti-friction rollers at against which the. lower 'section 7 contacts when the door is Closed. On one of the guideways l provide a holt 3" that is adapted to slide in beyond the door sections when the),7 are raised and moved to one side oi: the door opening to prevent the door sections from sliding out into the doorway when the car is in motion. The lower section 7 is prevented from sliding hy the next one above by asuitahle stop 1B provided near the lower edge ot said section.
For the 1nirpose`` of raising the door tions when the car loaded and the grain pressing against the :inside ofthe door, l provide a chain or other flexible means 14 attached to the-lower section and carrying 90 lever lo having one end that is adapted to enter holes It in plates 1T that are secured transversely to the `ijiiddle portion of each door section` as shown in Fig. 2. l n Fig.. 6 a imilar lilting apparatus is provided except that two Chains 18 are used 'for the levers 'lll and two sets ot' plates QOare secured to the surfaces of the door sections. The levers t9 are inserted into soclicts '19 in the guideways and through a'ples 19 on the edge 't0n of the sections 7. Vv hen it is desired to raise the lower section these levers can be; easily and quickly removed and adjusted for use.
-At the topfof the door is a track 2l wherew on hangers QQ are adapted to slide', said hangers having hooked lower ends to engage staples 23 in the upper edge of the door. At one side ot the door opening is a Way 2-t ot suticientwidth to receive the door sections placed side by side, and one ot the f rufideu ways at the side of the door vhas a hinged upper section 25 that is adapted to swing les /jjipping/by onefanoiher, the wall of down away from the door casing and allow the collapsed door to be pushed from the door opening.
A bar 26 is hinged at the top of the car and has a hook and staple fastening device 27 at its lower end for holding the door in place upon the guideway. The door sections have holes 26 therein which are adapted to register when vthe sections are moved t'o a collapsed or folded position and bolts 27 are inserted into the holes to hold the sections together. The hangers 22p are inserted into the staples 23` when the door is folded andthe sectionssnspended within the recess in the wall of the car. The bar 26 also holds the upper section of the door in place across the `car opening and on the other side of the casing a bar 28 is t() extend down beside a recess 29 into avhiclif'one end of the upper door section is inserted. .j
I may prefer to provide plates 3() the edges of the door sections, said plates contacting with one another when the door is closed and forming grain tight/ joints between the sections. This construction is illustrated in Fig. 7. f
In Fig. 8 I lhave Ishown a series of telescoping sections 3,11232 and 33 arranged to slide one within anfother, the lower section having a cable 34 attached thereto with means 35 above the upper dsection for winding 11p-,the cable Iand drawing the sections togethej-=until both the sections 3 2 and 33 are included Within the section 31. When this ha been done the door is ready to be openin4 .if When theioaerator wishes to move the sec itinv S2 up injcd the section 31, (shown in 8)' he can w'nd the chain around the lever $5 mtil the slack is taken u i, or the lever ma be majde detachable rom the zhain 34 so it can b e hooked into another ink. i
It iWlll be. noted" hat the door; sections increase in length' from the bottom toward the top of the duor,.to adapt them for the verticdlf'ruideways, the grooves therein being step v ii'lre in a cross section of the guideway.' f
I claim my inventioni.
1. This' pmbination, with a freight car havingf'a'dooi opening therein and vertical guideways on each side of said opening, of a door .composed of sections arranged to slidevertic'allyI in said' guideways, the contiguous longitudinal; edges of saidffsections i id car 'aving a recess on one side o'f said'opening adapted to reccivethe/doo; sections when pushedi-nto Ithe re'cfefss at one side of the raised, and the guideway on that side of the car having a hinged upper portion arranged to swing down out of the path of the door sections and permit them to be moved into said recess, substantially as described.
2. The combination, with a freight car, having a door opening therein and vertical guide ways on each side of said opening, said guide ways consisting of a series of vertical grooves arranged parallel with and lapping by one another, and a door composed of a. series of sections having their ends litting respectively infsaid grooves, the adjacent longitudinal edges ot' said sections lapping by each other vertically'to forni grain tight joints, means disposed in said joints between the sections for holding said lapping edges together and permitting them to slide vertically upon one another, means for lifting said sections, said sections being ca.- pable, when raised, of sliding by one another until the upper and lower edges of the lower Sections are flush substantially with the corrcsj'ionding edges of the upper section, and
the side wall of said car having a recess therein to receive the said door sections when so collapsed, and means for temporarily closing said side wall recess substantially as described.
3. The combination, with a freight car having a door openingtherein and vertical guide ways on each side of said opening, said guide ways including comparatively shallow ygrooves arranged parallel with one another and lapping by cach other and gradually increasing in depth from the bottorn to the top of said guide ways, whereby seats will be formed at the lower end of each groove, a door composed ot sections ot ditferent length arranged to slide vertically in said grooves, the longitudinal edges of the adjacent sections lapping by one another in their respective grooves, interlocking means mounted onsaid sections and adapted to hold said lapping edges closely together and permit the free vertical movement. of. said sections, means for raising said sections until the edges of the lower sections are llush sul stantially with the corresponding edges ot the upper section, and said car wall having a. recess at one side of the door opening therein to receive said sections when so eollapsed, substantially as described.
In witness whereof, I have hereunto set my hand this 19t-h day of February 1908.
