Specification of Letters Patent.

Patented May 18, 1920.

Application led .Tune 26, 1919. Serial No. 306,946.

To all whom z'z may concern:

Be 1t known that we, NEAL SMITHBAGK and WILLIAM HENRY METER, citizens of the United States, and residents of Madison, in

which is adapted most especially for use' with grain cars, grain storage structures or the like.

An'important object of our invention is to provide a grain door of this type with an outwardly swinging section and inwardly swinging sections, the inwardly swinging sections being positively prevented from swinging outwardly beyond the. closed position of the door.

Another object of our invention is to prom` vide the inwardly swinging sections lwith means whereby they are swung to and normally held in predetermined position whether this predetermined position be the closed position of the doors when in use or the open position of the doors flush against the wall of the storage structure whennot in use.y

, Another object is to provide means whereby the doors will be automatically set in snug and leak-tight relation in closed position and may partake automatically of all the movements necessary in thel different phases of the operation of opening and closing.

Other objects and advantages resideincertain novel features ofthe construction,

combination and arrangement of parts and will become apparent as the description proceeds, reference being had to the accompany-- ing drawings, forming a part of this specification, in which 1 Y Figure 1 is an outside elevation of the door, a portion of the upper section being broken away,

Fig. 2 is a plan view in section along the line 2 2 of Fig. 1,

Fig. 3 is an inside elevation of the door, a portion of the upper section being broken away,

Fig. 4f is an end elevation `of the door, the wall of the car or storage structure being shown in section,

'more' fully described.

Fig, 7 is an end elevation of the upper swinging sections, the adjacent portion of the car walll being shown in section,

Fig. 8 is a top plan view of the lower sections, the positions taken by the inwardly swinging sections and the outwardly swinging section being shown in dotted lines,

Fig. 9 is an inside elevational-view of the lower sections, and

Fig. 10 is an end elevational lower sections.

.Referringk to the drawings the numeral 12 indicates a sill mounted on the lioor of the car or storage structure, 13 the wall of the car or storage structure and 14C the door opening. It is to be understood that if desired the sill may be omitted as the floor of the car or storage structure may be adapted to serve the purposes of the sill.

Vertical pintle 'rods 15 are seated in the sill 12 and are journaled in collars 16 fixed to the wall 13. The pintle rods and journal collars are positioned a substantial distance from the door opening for a purpose to be hereinafter more fully described.

rlhe swinging sections composing the door include upper inwardly swinging sections `17, 18, 19, and 20, lower inwardly swinging

sections

21 and 22 and aV lower outwardly swinging section 23. The inwardly swinging sections are hingedl to the vertical pintle rod 15 and the outwardly swinging section is hinged to the lower `inwardly swinging section 22 in a manner vto be hereinafter It is to be understood that while only four ofthe upper inwardly swinging sections are shown in the drawings, any desired number may be employed.

The swinging sections, with the exception of the lower outwardly swinging section 23 and the coperating structure of the swinging section 22, are identical and comprise hinge end pieces consisting of a hollow body portion 24.- having an open end to provide a socket and a closed end 25 integral with the body portion. Apertured ears 26 are formed integral with the closed end and are mounted upon the pintle rod 15. These apertured ears are preferably disposed adjacent the upper and lower ends of the hinge end pieces so as to bear against the collars view of the means, and is so arranged that its end bears against the inner end of the panel and tends to normally space the same from the inner end of the socket and to resiliently oppose movement of the panel beyond a certain point toward the inner wall of the socket.

A. meeting end piece 29 consists of a hollow body portion having an opened end to provide a socket and a closed outer end and is disposed on the outer end of the panel, the reduced portion of the panel being accommodated or housed in the socket of the meeting end piece. The outer closed end of the meeting end piece presents a substantial face which abuts againstl a similar face presentedy by the adjacent meeting end piece when a pair of the swinging sections are in closed position. Each pair of swinging sections have the meeting faces of the end pieces 29 provided with a tongue 30 and groove 31 which interiit in the closed position ofl the swinging sections.

A coil spring 32 is mounted on the pintle rod between the apertured ears of each of the upper sections and has one end abutting one of said ears and the other end abutting against a shoulder or the like provided on the collar 16. This spring is normally so arranged as to tend to swing the upper sections` to closed position and to resiliently hold them in thisposition. It is to be noted, however, that this spring may be reversed so that itstendency will be to swing the sec` tions around to position flush against the car wallin the event it is desirable to have the door opening unobstructed and the swinging sections entirely out et the way.

The lower swinging

sections

21 and 22 are mounted on the pintle rod in the same manner as the upper inwardly swinging sections and all of these sections have a substantial portion of their length bearing against the car wallfand this feature of arrangement absolutely precludes any possibility of the inwardly swinging sections moving outwardly beyond their closed position. The inwardly swinging section 22 is approximately half the length of the other. sections and has its outer endfccnstructed so that the outwardly swinging section 23 may be hinged thereto as shown in the drawing. The outwardly swinging section 23 and the lower inwardly swinging section 21 have meeting end pieces constructed and arranged identical with the meeting end pieces of the upper inwardly swinging sections.

The lower outwardly swinging section outwardly swinging section and the lower inwardly swinging section are provided with identical means for locking them individually to the car or structure floor inclosed position. This last-mentioned locking means comprises abolt 33 mounted on the outside of the sections and adapted to be seated 4in a keeper in the car iioor. rIlhis bolt may be spring retracted andlisprovided with means for retaining itin: locked position such` as a detent` 34;. The means for locking the sections together comprises a locking` bar 35 pivoted to the inwardly swinging section and adapted to be: seated in locked position in a keeper 36 secured to the outwardly swinging sectionas shown in Fig. 1. The adjacent horizontal faces of` all of the sections are beveled as shown in the drawing so that they overlap in closed position and provide a snug and leakftight joint.

In practicewhen the car or storage structureis loaded withy grain: thel parts are in the position shown in Fig` 1,.the weight of the grain aidingA in] maintaining the inwardlyv swinging sections in closed posit-ion and the outward swinging: section being,

locked in closed `position by the locking, means described. lVhen it is desired to unload. thegrain the detent isoperated to rclease thelockingboltandthe locking bar` is removed fremi the keeper to allowy the section 23 toswing outwardly'as; shown in Fig. 8. `Inithe event it is notdesirableto` use the doors or tohousethem in open position by reversing` the spring, as previously] described the pintle rods may be removed and the sections taken down. y e i Wie claim l 1.
