WILLIAM E. WILSON, OF MASON CITY, IOWA.

DOOR- CONSTRUCTION.

Application filed November 19, 1919. Serial no. 339,190.

To all whom it may concern:

Be it known that I, WILLIAM E. WILSON, a citizen of the United States, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements in Door Constructions, of which the following is the specification.

This invention relates to door and door frame construction, and more particularly that class of doors which are mounted for swinging movement to and from closed position.

Among the objects of this invention are to improve door and door frame construction, and to provide a door which is more simple in operation, more economical in construction and maintenance, and more eficient in use; further to providea door that may be easily operated, and yet securely held in closed position; further to provide a door which when swung into open position will be out of the way and held in open position by its supporting parts; further to provide simple and effective means for operating the door; further to provide improved means for locking the door in closed position; further to provide a door which will be effective in preventing the entry of rain, winds, and the like, through the door opening; and such further objects, advantages and capabilities as 'will later more fully appear.

My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment of my invention, I wish it to be understood that the same is susceptible of modification and change, without departing from the spirit of my invention.

In the drawings:

Fig. 1 is a vertical transverse section through a door frame, and showing the door sections in elevation.

Fig. 2 is a front view of the same, partly broken away for the sake of clearness.

Fig. 3 is a horizontal transverse section through a portion of a'wall embodying my invention.

Fig. 4 is a fragmentary perspective view of a portion of the frame work and cross bars.

Fig. 5 is a fragmentary view of the lower end of one of the operating levers, showing how the same is locked in the door open.

Fig. 6 is a view similar to Fig. 5, but showing a modified construction.

Referring to the drawings:

Built into or arranged in connection with the wall A are the upright side portions of the door frame 1, which in Fig. 1 are shown of reinforced concrete. The vertical reinforcing rods 2 being encircled at spaced in tervals by the looped ends 3 of the cross bars 4, which are in turn spaced from the door stops 4, by means of spacers 5, which are in turn secured to the door stops 4 and cross bar 4 by any suitable means, suchas bolts, or

position to hold the like, as shown. The door sill 6 connects the upright portions 1 at the bottom of the door, and has embedded therein the bottom cross member 4, and the angle iron 8, extending across the frame, and serving as stiffeners therefor, and as a protection for the sill. The door which is designated generally by D, comprises the flange portions 9 extending therearound, and which as is seen in Fig. 3 engage at their sides the door stop 4, and at the bottom (see Fig. 1) the sill angle iron 8.

The supporting and swinging means for the door comprises the L shaped irons or arms 10, extending through the brackets or stirrups 11, mounted on the cross bar 4, as shown in Figs. 1 to 4.

These L shaped arms are bentat 12, and extend from thence downwardly to the journal box 13, where their ends are bent inwardly and suitably ournalled, as shown in Figs. 1 and 2. It is to be noted that the bend 12 is such that when the door is swung upwardly into open position, the longer leg of the L shaped arm will assume an approximately parallel position with the outer face of the Wall and door frame, and above the door opening. In the form shown in Figs. 1 to 4, I have provided the operating lever 14, which is suitably connected at 15 with the shorter leg of the L shaped arm, as shown in Figs. 1 and 2. The operating arm 14 is formed with the offset 16 (see Fig. 2) whereby to throw the extension adjacent one side of the door frame, and in a position not to obstruct the door opening. Upon the free end of lever 14 I have provided the pivoted latch 17 (see Fig. 5) which is permitted swinging movement in one direction, but preventedfrom swinging in the opposite direction by pin 18, which is fixed in the end of arm The latch 17 is pivotally mounted on the arm 14 by the pin 19.

From this construction it will be seen that when lever 14 is depressed to extend downwardly in a substantially vertical position as shown in the upper part of Fig. 1, the latch 17 will pass over and drop behind the bar 4, where it is held by reason of contact with fixed pin 18, until released by pushing forwardly on the lever arm, and raising the latch. This provides a secure and efficient means for locking the door in open position.

A modification of the latch 17 is shown in Fig. 6, in the form of the longitudinally slidable pin 17, which is normally held in extended position by coil spring 20, suitably positioned in the hollow end 21 of lever 14. Longitudinal movement of pin 1'4" is effected by upward pressure upon the collar 22, carrying the cross pin 23, which passes through latch pin 17, and has vertical movement in the slot 24. Viith this form of latch construction it is obvious that when lever 14: is swung downwardly, the latch 17 will ride over the upper edge of cross bar 4:, and drop therebehind under action of spring 20. Upward pressure on collar 22 will release this latch from behind bar 4:, when desired, in an obvious manner.

It is to be noted that each of the door sections D are so constructed along their edges that when the door is closed, they will form a substantially perfect weather seal along the joints between the door and door frame, and between adjacent sections of the door. It is also to be noted that in opening the door the upper edge will swing out first, and will be followed upon continued swinging with the separation of the joint at the bottom, in an obvious manner, thus provid ing a very efiicient door for use in silos, grain bins, elevators, and other buildings having a more or less elongated door opening.

Referring again to Figs. 1 and 2 it will be noted the handle 14 is removable by virtue of the readily separable joint 14; between the handle proper and the lower portion attached to the arm 10. By this arrangement I am enabled to use the same handle for all or any number of the doors by simply transferring it from one to the other.

Having thus described my invention, I claim:

1. In combination with a door frame, a door, a hinge comprising L-shaped arms pivotally connecting the door and frame, means for swinging the door upwardly, and means on said last mentioned means for automatically locking the door in open position.

2. In combination with a door frame, a door, a hinge comprising L-shaped arms pivotally connecting the door and frame,

means for swinging the door upwardly, and means carried by said swinging means to engage said door frame to lock said door in open position.

3. In a building construction, a door frame, reinforcing members in said frame, a support extending into said frame and being connected to said reinforcing members, a door, means pivotally connecting said door to said support, and means in said frame for holding said door spaced from said support when in closed position.

4. In building construction comprising masonry door frame members, spaced up right members forming door stops connected with said frame members,'cross bars connecting said upright members and spaced rearwardly therefrom, door units, and offset hinges pivotally connecting said door units and said cross bars to permit the door to swing upwardly.

5. In a'structure of the character described, a frame, projections extending therefrom, a door pivoted on one of the projections, a handle connected with the door for swinging same on its pivot, and a movable latch memher on said handle adapted to yieldably engage another of the frame projections so as to pass said projection when moving in one direction, but adapted to engage and not pass said projectionv when moving in the opposite direction.

6. In a structure of the character described, door frame members, supporting members wholly between the door frame members and secured at their ends thereto, l..-shaped hinge members secured to said supporting members and pivotally connected at their ends to the doors approximately midway of their lengths, means for turning the hinge members about their axes of rotation to swing the doors out of and into closed position. said turning means comprising an arm rigid with one of said members and a manual member detachably fastened to said arm.

7. The combination with a door frame and a door operatively coacting with the rear side thereof, a shaft journaled adjacent the upper end of the front side of the frame, a hanger depending from said shaft and be ing pivotally connected to said door, and means being connected to and extending laterally from one end of said shaft for swinging said door, said means carrying a keeper cooperable with said frame for automatically locking said door in opened position.

In witness whereof, I hereunto subscribe my name to this specification in the presence of two witnesses.

WILLIAM E. WILSON. Witnesses:
