Aug. 19, 1930. F. P. RIDDELL ET L COLLAFSIBLE WINDOW Filed Feb. 4, 1929 Patented Aug. 19, 1930 UNITED STATES PATENT OFFICE FRED P. RIDD'ELL AND JAY F. JOHNSON, F SUPERIOR, WISCONSIN COLLAPSIBLE WINDOW Application filed February 4,4929. Serial 110,337,315.

This invention relates to windows, and has special reference to one which may be extended or folded as desired, it being particularly adapted for use on locomotive cabs or the like where it becomes essential for the operator of the vehicle to have a clear, unobstructed vision both forwardly and backwardly, as well as laterally. Furthermore the invention is designed to be applicableto dwelling houses, apartments, or the like.

The principal object is to provide a practical and simple device of this character hav ing novel and advantageous features heretofore unknown.

Other objects and advantages of the invention will appear in the further description thereof.

Referring now to the accompanying drawing, forming part of this application, and

wherein like reference characters indicate like parts:

Figure 1 is a perspective view of one of our improved windows as viewed from the interior thereof and the window slightly less than fully extended;

Figure 2 is a diagrammatic fragmental perspective view of the principal operating parts;

Figure 3 is an end elevation of the window fully extended; and

Figure 4 is an enlarged perspective view of the end window connections with the major window.

1 represents a frame which may be insertible within a window opening, or may represent the fixed frame of the window, as preferred. To this frame is hingedly united the bottom, end, and top sashes, 2, 3 and 4; respectively, all of which may or may not be glazed as desired.

Intermediate of the end sash 3, below the top sash 4t, and abutting the outermost edge of the lower sash 2, is installed the major sash 5, which is susceptible of lateral upright motion only, it being slidably carried by the end sashes 3. This slidable connection comprises a horizontally disposed groove 6 upon the inner face and adjacent each end of the end sashes 3, and which groove may be accomplished by the spaced strap irons 7 over a 'rabbetmade in the face of the sash, or itis obvious that there maybe formed a grooved strap in its entirety. Into this groove is slidably fitted the head of the T projection 8 on the butt 9, and which butt is fastened as by screws or the like into the outer face of themajor frame or sash 5.

This attachment of the major sash to the end sash obviously restricts the motion of the former to an outer or inner position while held vertically, and when wholly withdrawn to a plane substantially'with that of the inner face of the frame 1 the end sashes will fold inwardly against the outer face thereof.

Upon-the inside of the central mullion 10 of the major frame. or sash is vertically reciprocably mounted the operating bar which is provided with an outwardly bulged handhold portion 11, andits uppermost end 12, which lies prone against the mullion, is slotted vertically as at 13 and designed to be held against. the mullion by means of a suitable pin orscrew 14. The lower extension 15 of the operating baris preferably reduced in width and held against the mullion as by a clip'16through which it'readily slides, and the lower extremity'of the portion'15 of the bar is. also slotted as at 17 and engages the 'L-shaped neck 18 of thecbutt 19 which is fastened to the under side ofthe outer edge ofthe bottom sash 2 forming as it were a loose connection between the outer edge of the sash 2. and the lower edge of the major sash 5.f The innermost end of the L or gooseneck '18 is formed with a T shaped head 20 5 which fits withina vertical groove or slot 21 formed in the mull-ion or by two spaced stepped straps 22 aspreferred; this groove being disposed vertically just back of the extension 15. of the operating bar so that when the operating bar is raised it will cause the .T-shaped head of the butt 19 which carries, the sash 2 to be raised simultaneously with the bringing in of thesash 5, or lowered simultaneously withthe thrusting outwardly, 'ofsaid sash; The lower extremitiesof the straps 22 are turned inwardly under the edge of the sash 5 so as to form a convenient pivotal connectionforthe T-shaped head so,

thatitheQs'atS'hS 2 and .5, may readily lietogether when the window is closed or assume a limited right angular relation when opened.

The upper or top sash 4 is hinged as at 23 5 to the upper innermost edge of the frame 1 preferably as with spring hinges biasin the sashin okoeed relation, and it is designs to rest%-brgravityeombined with the hasing effect of the hinges upon the inclined m uppermost ends of the sashes 3 so that when they are swung outwardly by an outward movement of the sash 5 they will naturally a swing out and raise the top sash 4. Likewise when drawn in agaimte closed ition the 15 Sushi will assume its vertical fol ed position 7 fim'eagainst and may be mortised temporarily theseimaswell as the end sashes. '.Erom the ,foregoi it is evident that we have devised an exee ingly simple and praczo window. which may be emplayed for examplein dwellings, apartments, or the like, as.acooling shelf on which milk bottles,etc., may be deed-"for keeping same cool; or fer use by c 'ldren in viewing in all Q5 dfileeetions without the danger of falling therethmngh;

Hauling thus described our .inventiom what we claim and desire to secure by Letters Pateat is: t,

A'collapsible window of the type deser'bed comprising a supporting frame, a major nperating sash,end sashes hingedly unitflai the frame and supporting the major when bottomsash hinged to the frame and 3 operated by the major sash, and a top sash for thelpurpom described. 2.
