GEORGE PAGET, CHARLES E. PAGET, AND ARTHUR EDWARD PAGET, OF HUNTSVILLE, ONTARIO, CANADA.

GRAIN-CAR DOOR.

T 0 all whom it may concern:

Be it known that we, GEORGE PAGET, CHARLES EDWARD PAGET, and ARTHUR EDWARD PAGET, all of the town of Huntsville, in the district of Muskoka, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is the specification.

Our invention relates to improvements in grain car doors, and the object of the invention isfirst-to devise a means for fastening the door in position at the sides, which will insure of no crevices being formed between the sides of the doors and the jambs due to the racking or jolting of the car secondlyto provide an improved means of holding the door in position without interfering with the ordinary jamb-thirdlyto provide a simple means for locking the door from rising until it is released at the sides of the jambs-fourthly-to devise a simple means at the bottom of the door for raising the door as soon as it has been released at the sides-fifthlyto improve the operating mechanism for securing and releasing the sides of the door in relation to the jambs andsixthlyto devise an improved means of conveniently handling the door. To effect these objects we have constructed our door and the jambs thereof in the manner, which we shall presently describe.

Figure 1, is a perspective View of portion of a door showing the jambs and supplemental jambs with which it co-acts, so as to close the door opening. Fig. 2, is a vertical section through the fastening devices at the sides of the door. Fig. 3, is a view of portion of the side of the door showing it broken away. Fig. 4, is a sectional plan intermediately broken away. Fig. 5, is a perspective detail showing portion of the bottom bar of the door provided with a means for raising it. Fig. 6, is an alternative form of Fig. 5. Fig. 7 is a section on. line 77 of Fig. 4.

In the drawings like letters of reference indicate corresponding parts in each figure. A A are the door jambs and B the sill.

C are the longitudinal boards of the grain door.

1) D are the end vertical battens, which are placed within the ends of the longitudinal boards C so as to leave projecting Specification of Letters Patent.

edges C of the boards, which fit at the inside to the inside of the door jamb.

C and C are the longitudinal upper and lower battens and D is the diagonal batten.

F are vertically grooved supplemental members secured to the door jamb on the inside thereof. The groove has a curved portion F at the lower end as shown in Fig. 7

E are the securing bars, which are provided with slots E through which the bolts E and E project. The slots E allow of lateral movement. The heads of the bolts E are on the outside of the door and the fastening nuts E on the inside. There are four bolts shown. The bolts E and E are provided with enlarged portions forming shoulders 4 and 5. The portions 5 being deeper than the portions 4 so as to extend through the plates G and bars E.

r 6 are washers which encircle the bolts E and E and are located in recesses formed in the battens D.

By means of the portions 4: and 5 and the washers 6 the heads of the bolts E are prevented from binding the plates G and bars E and also a good bearing surface is provided by the washers for the bars E to slide upon.

G are plates provided with diagonal slots through which the bottom bolts E and also the bolt next to the top bolt extends.

The bottom of the bar E is bent at E as indicated for the purpose of allowing the bottom end of the bar E to slide inside of the bar H.

H is an angle bar secured as shown in Figs. 2 and 3 to the bottom of the door. In the front face of the bar H rectangular slots are punched. The punchings H thereof are turned baekwardly into a recess H formed in the bottom batten C of the door. In Fig. 6 we show an alternative construction of this bar in which the punching of this slot is turned outwardly instead of inwardly into a recess.

I are reinforcing plates riveted on the securing bars E and extending upwardly over the plates G and through-which the bolts E extend. The outer ends of the plates E abut against the vertically grooved members F, and the offsets E engaging with the curved portions F of the grooves in members F prevent the door being raised until the securing bars have been withdrawn volved in our invention we shall briefl describe the operation and utility of the same.

The grain door is placed in position from the inside with the edge of the batten D against the inner side or edge of the groove member F. The plates G are then moved downwardly and thereby throw the bars E outwardly into the grooves of the members F that is, in a position shown in Fig. 1 of the drawing. It will thus be seen that the door is securely held in position and the grain may be poured into the car and all the effect will be to hold the projecting edges C of the door tight against the members F which practically form part of the door jamb thereby serving to aid in making the door grain tight. The securing bar E enters the vertical groove of the member F also further aiding to make the door grain tight. The offset E on the plates E fitting in curved portion F of the groove in the member F serve to prevent the door rising from the sill when it is in its closed position.

In order to remove the door when the car is filled with grain all it is necessary to do is to push the plates G upwardly so as to carry the securing plate E out of the groove of the member F and plate I away from such members and then insert an ordinary lever into the holes formed in the bar H and pry the door upwardly thereby allowing the grain to discharge underneath the bottom of the door into a suitable receptacle. When a larger quantity of grain has been discharged the door will fall back of itself on to the heap of grain remaining and will be entirely free.

Such a grain door as we have described will insure of no crevices being formed between the edges of the door and the jambs owing to the racking movement of the car and allowing the grain to leak therethrough. Also a door such as we have described may be easily and quickly locked in place or removed when desired.

I What we claim as our invention is:

In a grain car door, the combination with the door, of a vertical grooved member located in the door way at each end of the door having offsets formed in the groove and tongue members secured on the face of the door and slidable longitudinally of the door into the groove of the grooved members and having offsets fitting the offsets of the groove, as and for the purpose specified.
