Eradication 1 en Patented Nov. 13, 1917.
Application filed August 24, 1816. Serial No. 118,867.
To all whom it may concern:
Be it known that I, JASPER Jnnomn Seam, a citizen of the United States, and a res1dent of Coupeville, in the county of Island and State of l/Vashington, have invented certain new and useful Improvements in Automatlc Garage-Doors, of which the followlng 1s a full, true, and exact s ecification.
My invention is an improvement in doors or gates for carriage-ways, particularly for garages or analogous structures, wh1ch are operated automatically by the welght ofa vehicle as it approaches the doors.
The details 0 construction, arrangement, and operation of parts are as hereinafter described, and illustrated in the accompanyin drawing, in which:
igure 1 1s a plan view of a garage w1th my invention applied, a POItlOllOf the gara e cover being broken away.
ig. 2 is a vertical section on the line 22 of Fig. 1.
Fig. 3 is a detail view of the means for locking the doors.
Fig. 4 is an enlarged sectional elevatlon on the line 4-4 of Fig. '1.
Figs. 5 and 6 are fragmentary perspect1ve views illustratin the means for automaticall 0 crating t e doors.
Fig.7 is a detail sectional view of certain parts shown in Figs. 5 and 6.
Referring more articularly to the drawings, numeral 1 in icates the outside frame work of a garage having a front door opening. My device is set 1n the door opening and includes a bottom frame work 2 upon which pivotally rests a vertical door post 3, one at either side of the door opening. Posts 3 are pivoted at the bottom 0 frame work 2 and at the top of the door frame 4. Near the lower end of each of the posts spiral slot 5 is formed-see especially Figs. 3, 6,7. A cross bar 6 is positioned horizontally between posts 3 with its ends passing through the slot 5 and extending somewhat beyond the posts. Doors 7 are rigidly secured to posts 3 and normally extend inwardly and meet at the center of the door opening. In order to open the doors it is necessa to depress the cross bar 6 whose ends sllde vertically in slots 5 and thereby rotate the door osts 3 thus swingin the doors 7 open. Elangers 8 are suspen ed from cross bar 6 and provide bearings for the adjacent ends of inclines 9 and 10. Incline 9 extends within the garage and is pivotally supported upon frame work 2 at its inner end. Incline 10 extends out beyond the 1garage and is pivoted at its outer end. ar 6 and the adjacent ends of the inclines are normally held in a raised position by means of counterweights 11, one at either end of the said bar. "The counterweights 11 are suspended on cables 12 which pass over pulleys 13. It will be understood that considerable weight is required to depress either of the inclines and that the necessary weight will be much reater than that of an ordinary man but t at an automobile running up on the incline will be sufficient to overcome the counterweight and cause the doors to swing open. A special door locking device is provided for the inside of the garage WhlCh includes levers 14 which are ivotall and loosely mounted upon a.- s aft 15. he inner ends of levers 14 project beneath a trip plate 16 which is adjacent the inner end of incline 9 and which must be v driven over before the incline 9 is reached The inner ends of levers 14 engage cranks 17 which are rigidly connected to a transverse shaft 18. Vertical levers 19 are secured to a transverse shaft 18-see Figs. 1 and 3-and their upper ends are pivoted to shorter levers 20, which are in turn secured to angular yokes 21 that slide 'on vertical rods 22, fixed on the frame of the arage and encircled by spiral springs 23. T normally support the levers in the osition shown by full lines, Fig. 3. The ugs or blocks 24 project forward from levers 19 and beneath the end of cross bar 6, thereby normally locking the said bar so thatit cannot be depressed and the doors opened until the lock is released. Means for unlocking this device are included and consists of a combined hand and foot lever 25 secured to the end of shaft .15 and adapted to engage a quadrant 26. Spring arms 27 are secured to shaft 15 and project beneath the lever 14 intermediate between the shaft 15 and the shaft 18. *When the lever 25 is drawn backward the spring members 27 raise the inner end of lever 14 which artially revolves the crank 17 and causes t e shaft 18 to rotate a small fraction of a revolution. The rotation of shaft 18 throws the lever 19 and withdraws the locking lugs or blocks 24 from beneath the ends of bar 6 and through the medium of link 20 depresses the sprin 23. In other words, as the shaft is rotate a part of a revolution by the means dehe springs scribed, the levers l9 and are thrown hee ward into an angular relation to each other, as shown by dotted lines, Fig. 3, whereby the locking lugs 2% are withdrawn from beneath the bar 6, so that the weight of the lever inclines 9 and 10 carries them down to horizontal position, and the doors 6 and 7 are then at thesame time swung open by the action of the bar 6 in the spiral slots or posts 3. The position of the doors when open is indicated by dotted lines, iig. 3L. lhe locking means may be retained in an unlocked position by means of a lever and quadranttZG, the latter having notches to receive the lever when thrown back.
The lever has a rigid lateral arm 25 to which the operator may apply foot-pressure to aid in throwing and locking the lever. When not retained in an unlocked position, the action of an automobile driven upon trip plate 16 depresses the outer end of the lever 1a and removes the bolt as previously described. It will be evident that the garage may be entered from the outside only when the locking lugs 24 are in an unlocked position and that when leaving the garage empty it is usual to withdraw the bolts 2e by means of the lever 25 so that when returning the weight or the car will automatically open the doors.
1 claim l. The combination with vertical rotatable naeereo posts spaced apart and having spiral slots, and vertical doors supported on said posts,
or a transverse counterweighted bar which is movable vertically, and whose ends proect through said slots and are thus adapted when depressed to rotate the posts; lever ining the bar in raised position, such means comprising pivoted spring-supported locking levers having lugs normally projecting under the said bar; a trip plate pivoted adjacently to the outer end of one of the inclines; and devices operatively connecting such trip plate and the locking levers, as described.
2. The combination with a swinging door, and vertical pivoted posts having iral slots, of a transverse counter-weig ted bar projecting through the slots; lever inclines'pivbted on opposite sides of the bar and their inner ends supported by the latter; means for locking said bar in raised position and thus in turn supporting the inclines; and means for tripping the locking devices to permit the inclines to descend and the doors to swing open, as described.
