DOOR-RELEASING' MECHANISM.
Specification of Letters Patent.
Patented Aug. 2, 1910.
Application filed December 28, 1909. Serial No. 535,375.
To all whom 'it may concern:
Be it known that I, THOMAS BRAXTON RANKIN, a native citizen of the United States. residing on Nettleton Rural Route, in the county of Itawamba and State of Mississippi, have invented new and useful Improvements in Door-Releasing Mechanism, of which the following is a specification.
This invention relates to door openers, and particularly to one adapted for use upon the doors of a barn or the like, means being employed whereby the doors of the barn can be automatically thrown open at the time of a re to permit the escape of live stock.
Another object of the invention is to provide a novel form of alarm operable auto-- matically upon opening of the doors.
The above mentioned and other objects are attained by the construction, combinations and arrangements of parts, as disclosed on the drawings, set forth in this specication, and particularly pointed out gin the appended claims.
In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views:-Figure 1 is a sectional elevation of my improved door opener sho-wing it applied to a barn or similar structure whose walls are provided with swinging doors or closures. Fig. 2 is a section taken vertically on the line 2 2 of Fig. 1. Fig. 3 is a sectional elevation of the trip shaft. Fig. 4 is a sectional elevation of one of the latch releasing shafts. Fig. 5 is a sectional elevation of the said trip shaft taken at right angles to Fig. 4 and showing one of the yieldable supports for the shaft. Fig. 6 is a sectional elevation showing the manner in which the sections o-f the shaft are coupled to each other. Fig. 7 is a section taken on the line 7 7 of Fig. 6. Fig. 8 is a 4sectional elevation of a portion of one of the door hinges. Fig. 9 is a sectional elevation of the said hinge taken at right angles to that shown in Fig. 8. Fig. 10 is a sectional elevation of one of the latch members. Fig. 11 is a sectional elevation of the alarm. Fig. 12 is a sectional elevation of a slightly modified form of door. Fig. 13 is a diagrammatic View of a slightly modified form of alarm. Fig. 14 is a diagrammatic view of the bell actuating member of the alarm.
,In Figs. land 2 of the drawings, I show a barn, stable or similar inclosure, the side walls 1 each being provided with a plurality of hinged or swinging doors 2, the hinges being disposed vertically so that the doors can open from the sides of the walls. The doors can be arranged at any suitable points in the walls but are preferably located at points adjoining the stalls in which the live stock is stationed. Longitudinally extending squared shafts 3 are mounted within the inclosure at points slightly above the door openings. These shafts are arranged in parallel relation with the side walls 1 and each of such shafts is formed from a plurality of short sections whose meeting ends are joined by coupling members 4f, such screws being carried by the coupling members to engage the said shaft sections to hold them operatively positioned in the coupling members. These shafts have their bearing members revolubly mounted in the partitions .5 and' in the end walls 6 of the inclosure. Each shaft is provided with a plurality of horizontally extending fingers 7, each being positioned adjacent to one of the end walls. The shafts are engaged by flat leaf springs or similar equivalent elastic elements 8 which exert their tension to hold the fingers 7 normally in their horizontal positions.
A trip shaft 9 is journaled in the walls of the inclosure and is provided with trip ngers 10 which Vare disposed immediately above co-engaging fingers 11 upon the shafts 3. When the shaft 9 is revolved in one direction the trip fingers 10 will be engaged with the ngers l1 to revolve the shafts 3 against the tension of the springs 8. The shaft 9 has extending therefrom a crank arm 12 to which is secured one end of a Hexible connection 13 or equivalent operating cord or the like. This cord or connection is engaged with an antifriction roller 14 and the outer end is attached suitably to an operating lever 15. This lever may be located at any suitable point but it is preferably stationed in a house near to the barn or inclosure. Should the occupant of the house detect the odor of smoke or should he discover that the barn is on fire he could conveniently operate the lever 15 to actuate the shaft 9 for a purpose to be hereinafter more fully disclosed.
The side walls 1 of the inclosure or barn carry casings 1G which are arranged immediately above the door opening. Each easing is provided with a vertically sliding bolt 17 upon=Which iis for1ned^afreduced-= stem le. Each casing is provided with an expansion sprlng 19 which surroundsthe stem 18 and exerts its tension against the bolt Ytoi normally hold it engaged'fwvith 'its` mounted upon the shafts' torotate"there'1 With' 'and the* outerendsof the said dogs are formed into `Wings24Whichare normally' positioned beneath shoulders 25ct the"bolts` 175 Theoute'rlends ofthe" lips"l 21 areidis' posed 'bene'athisho'ulders' 26 upon 'the' said bolts.'M Whenthe shaftsi are rotated intheV direction'of 'the arrow shown i'irFig.' 10 the' lugs'22 v'vrllk befmoved' into such engagement With the lips`21 to impartthereto rocking movement which i'nvement'vi'll be imparted' to thefslid'ingbolts tormove them out ofen# gagement with 'their keepers Q0.
Each hinged door is'piovided'with a plu! rality of eye members' 27 which arearranged" in lsuperii'npo'sed relation asl shown, thelow'i" ermost `member 'being provided i with a revL oluble vroller-"28 Which'is slidableupon fan" angularly disposed track-29'npon the upper inclined surfaceV of a postBO.
