Application filed April 20, 1916. Serial No. 92,447.

l '0 all whom it may concern Be it known that we, Jlwon \VAiirAcri and HENRY WAMPACI-i, citizens of the United States, residing at Jordan, in the county of Scott and State of Minnesota, have invented certain new and useful Improvements in Mountings for SiloDoors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention which relates broadly to improvements in silos has for its object to provide a supporting frame applicable to the numerous doors thereof for hingedly supporting said doors and at the same time serving to form a ladder by means of which a person may ascend to any required level.

lVith this general object in view, the in vention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a front elevation of a portion of a silo. showing the application of a pair of improved frames thereto; Fig. 2 is a horizontal sectional view taken on the plane in dicated by the line 22 of Fig. 1 showing one of the doors open and another closed; Fig. 3 is a vertical section as viewed on the planes of the line 33 of Fig. 1; and Fig.4 is a perspective view of one of the aforesaid frames.

In specifically describing the structure shown in the drawings above briefly described, similar characters will be placed on coresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective indices. To this end, thenumerals '1 designate the vertically alined door frames of va silo 2, such frames being of the usual or any preferred shape and being normally closed by suitably constructed doors 3 which are adapted to open inwardly. Each door 3 ismounted on a frame 4 whose construction constitutes the gist of the present invention.

Each frame t includes a pair of horizontal metal bars 5 spaced outwardly from the frame 1, one end of said bars being bent rearwardly at right angles as disclosed at 6 and curled upon themselves to form upright hinge knuckles 7 receiving therein pintles 8 carried by one upright side of the door frame. The other ends of the bars are riveted or otherwise secured toan upright bar 9 and the uppermost of said bars '5 projects beyond the bar 9 as shown at 10, this portion overlying a metal finger 11 which is secured to and projects forwardly from the frame. This linger and the extension 10 serve to support the free end of the bars 5 to prevent sagging thereof when said bars are in use as a ladder. A pair of arms 12 extend rea-rwardly from the intermediate por tions of the aforesaid bars 5, said arms being preferably constructed of metal bars and having laterally bent ends 13 which are riveted or otherwise secureo to said bars The free ends of the arms 12 are curled upon themselves to provide hinge knuckles l alining vertically with other knuckles 15 carried by the door '3, pintles 16 being passed through said knuckles whereby the door is hingedly connected with the arms 12. For the purpose of imparting the necessary rigidity to the arms 12 and preventing sag ging thereof when the weight of a person is supported by either of the bars 5, said arms are preferably connected by crossed braces 17 whose ends :are riveted thereto.

The edge of the door 8 is provided with a projecting ange 18 adapted to limit the closing movement of said door, and for the purpose of holding the latter in closed position, a suitable latch 19 is provided, said latch preferably consisting of a rock shaft 20mounted rotatably and slidably in a bearing 21 secured to the frame 1, one end of said shaft having thereon a cam 22, while the other end thereof is equipped with an operating lever 23. In most cases, for ease of construction, the lever 23 and cam 22 will be formed by bending the ends of the shaft 20 as shown, but it will be obvious that other structures may well be provided and in fact totally different types of latches may be employed if found desirable.

In order to release the latch 19, the lever 23 is raised and shifted longitudinally to remove the cam 22 from the inward path of the bar 9, said cam being normally in contact with the rear side of said bar. WVhen this has been done, the entire frame 4 may be swung inwardly through the door frame 1, thereby opening the door 3 as shown in Fig. 2. By constructing the frame at in the manner shown and described, it will be highly efficient and durable yet it may be inexpensively manufactured and easily applied by unskilled hands. The improved frames will be employed on the nu merous doors 3 and not only serve as means for holding said doors closed or open as the case may be, but they also act as a ladder by means of which a person may ascend to any desired door for entering the silo therethrough.

From the foregoing, taken in connection with the accompanying drawings, the construction, manner of operation and advantages of the invention will be readily understood without requiring a more extended explanation. In conclusion, however, we will state that although certain specific details of eons ruction have been shown and described for accomplishing probably the best results, numerous changes may be made within the scope of the invention as claimed without sacrificing the main advantages thereof.

We claim:

1. The combination with the door frame of a silo and an inwardly opening door therefor; of an upright supporting frame hinged to one side of said door frame and adapted to swing into the silo through said frame, a hinge connection between the door and said supporting frame, releasable means for normally preventing swinging of said supporting frame, and coacting stops on the two frames for preventing sagging of the free end of said supporting frame, whereby the latter may serve as a section of a ladder.

Copies of this patent may be obtained for upright bar secured at its ends to the other 2. The combination with the door frame of a silo and an inwardly opening door thereof; of a supporting frame hinged to one side of said door frame and adapted to swing into the silo through said frame, said supporting frame including a plurality of horizontal has adapted to serve as ladder rungs, a hinge connection between the door and said supporting frame, releasable means for normally preventing swinging of said supporting frame, and a rigid stop projecting from said door frame and underlying one of the horizontal. bars of said supporting frame to prevent sagging of the latter.

3. A frame for supporting silo doors, said frame comprising upper and lower horizontal bars havin means at one end for hinging them to one side of the door frame an ends of said horizontal bars, one of the last named ends being extended beyond said upright bar and being adapted to overlie a stop fixed to the door frame to prevent sagging of the supporting frame and a pair of rigid arms secured to and extending laterally from the intermediate portions of said horizontal bars, said arms having means at their free ends for hingedly connecting them 5 with the door.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
