DISAPPEARING GARAGE-DOOR.

Specificatiou'of Letters Patent.

Patented Apr. 2, 1918.

Application filed April 26, 1917. Serial No. 184,736.

To all whom it may concern:

Be it known that I, GEoRoE B. BOUGHTON, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Disappearing Garage- Doors; and I 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.

My invention relates principally to garage doors for use in limited space, although it is to be understood that the invention could well be-used upon other kinds of buildings.

The object of the invention 'is to provide an improved door and operatin means therefor, so constructed as to posltion the door in the upper part of the garage or other building when the same is opened, whereby it will be entirely out of the way and will therefore render all space in the building available for other purposes.

With the foregoing general object in view, the invention resides in the novel features of construction i and 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 vertical section of a garage having one of the improved doors, the latter being shown in closed position;

Figs. 2 and 3 are similar views showing the door respectively in partially and completely opened positlons;

Fig. 4 is a vertical transverse section on the plane of the line 4-4 of Fig. 1.

In the drawings above briefly described, 7

the numeral 1 has reference to a garage having a door frame 2 equipped at its sides with vertical tracks 3, whereas the numeral 4 designates the door which is shown as formed of upper and lower sections"'5 and 6, respectively, hinged together at 7, the lower end of the section 6 having rollers or other shoes 8 traveling in the tracks 3.

Cables 9 and weights 10 are preferably employed 'to assist in opening the door, said cables being secured to suitable ears 11 on the lower section 6 of the door, and passing over pulleys 12 adjacent the upper end of the door frame. Although the use of the cables and weights is preferable, it is highly probable that other construotionscould well.

be adopted for attaining the same results and I do not therefore w1sh to limit my invention in this respect.

Two inclined levers 13 are fulcrumed between their ends to brackets or the like 14 secured to the sides of the garage, the upper ends of said levers being rigidly secured at 15 to the upper door section 5, adjacent the upper end thereof,.whereas the lower ends of said levers are provided with counterbalances 16 adjustable along the same and held in adjusted position by set screws or the like'17. Rigid arms 18 extend from the upper portions of the levers 13 and are rigidly secured at 19 to the door section 5, adjacent the lower end of said section, said arms and levers being preferably disposed in right angular relation, although this is not altogether essential.

By the construction shown and described,

the door may be easily operated and as illus- I trated in the drawings, it will move to a horizontal position in the upper portion of the building, when opened, in which location it will occupy no valuable space. The improved door is therefore of great advantage over those of the hinged type or those mounted slidably on tracks and hangers.

Since probably the best results are obtained from the specific construction shown, this construction constitutes the preferred form of my invention. I wish it understood, however, that within the scope of the invention as claimed, numerous minor changes may be made without sacrificing the principal advantages.

I claim:

1. The combination with a building and a door frame thereof, of a door for said frame formed of horizontal hingedly connected sections, tracks at the sides of the frame and terminating at he upper end thereof, shoes on the lowermost door section engaged with said tracks, inclined levers fulcrumed between their ends for movement in vertical planes at right angles to the door frame, the upper ends of said levers being rigidly secured to the uppermost door section, and counterbalances on the lower ends of said levers.

2. The combination with a building and a door frame thereof, of a door for said frame formed of horizontal hingedly connected sections, tracks at the sides of the frame and terminating at the upper end thereof, shoes on the lowermost door section engaged with said tracks, inclined levers fulcrumed between their ends for movement in vertical planes at right angles to the door frame, the upper ends of said levers being rigidly secured to the uppermost door section, adjacent the upper end thereof, arms extending laterally from said levers and secured to said uppermost section adjacent the lower end thereof, and counterbalances on the lower ends of said levers.

3. lhe combination with a building and a door frame thereof, of, a door for said frame formed of horizontal hingedly connected sections, tracks at the sides of the frame and terminating at the upper end thereof, shoes on the lowermost door section engaged with said tracks, means connected with said lower section and exerting a constant upward stress thereon, inclined levers fulcrumed between their ends for movement in vertical planes at right angles to the door frame, the upper ends of said levers being, rigidly secured to the uppermost door section, and counterbalances on the lower ends of said levers.

4. The combination of a building having a vertical door frame, a door for said frame formed of an upper and a lower section memes hinged together, a pair of levers fulcrumed between their ends at the sides of the building, said levers inclining upwardly at substantially 45 degrees to said door and having their upper ends secured to the upper end of the upper section of said door, arms extending from said levers and secured to said upper section, near the lower end thereof, counterbalances on the lower ends of said levers, a pair of shoes on the lower end of the lower door section, a pair of vertical tracks at the sides of the frame and terminating at the upper end thereof, said shoes engaging said tracks slidably and pivotally, a pair of cable guides of the frame, a pair of cables trained over said cable guides and secured at one end to the lower end of said lower door section, and counterbalancing weights on of said cables.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE B. BOUGHTON.
