9 claims'. (C1. 20-20) This invention relates to a head structure for an overhead door and of the general character illustrated in the (zo-pending applications, Serial No. 498,628, flied Nov. 28, 193D, entitled, Flexible doors, and Serial No. 614,894, liled June 2, 1932, entitled Folding sectional door.

The chief object of this invention is to provide a head structure that may be economically and cheaply manufactured and-so arranged that it may be readily adapted to different sized doors with but a minimum duplication of slightly dissimilar parts and whereby the maximum number of parts is capable'of utilization with diierent sized doors.

Another object of the invention is to incor-- porate in the headstructure an integral mounting for a pulley, the same being associated with a cable, in'turn connected tothe door and counterbalancing associated therewith. l

The chief feature of the invention, in addition to the accomplishment of the foregoing objects, consists in the detailed construction of the head structure and includedparts. Y

The full nature of the invention will be under stood from the accompanying drawing and the following `description and claims:-

rIn the drawing, Fig. 1 is a side'elevation of one of the head structure embodying the invention, the full lines indicating parts arranged for one size of door and the dotted lines indicating similar parts arranged for a second size door.

Fig. 2 is an enlarged sectional view taken on line `2 2 oiFig. l ,and in the direction of the arrows and showing thertrack. f.

Figs. 3 and 4 areelevational views taken at right angles of a part that may be associated with the portion of the head structure for adapting said head structure to another size of door from a predetermined size of door.

1n Figs. l and 2 of the drawing, 10 indicates a plate which is approximately of triangularshape, the hypotenuse of which consists of two curves that merge with eachY other, the upper curve beingv generally indicated by the numeral 11, while the lower is indicated by the numeral 12, the former being inwardly directed and the lat-- ter being outwardly directed. The lower end of As indicated in Fig. 2, a perpendicular flange 14,

extends from the side l5 at one end thereof, the side 15 being vinclined or offset at 16 and terminating inV aV track portion 17 and a retaining wall portion 18.v The purpose ofthe inclination is tospace the track portionfromthe back or side portion l15 so that the retainersfor the guide shoes or wheels that engage the track portions 14 and r1, or both, win be spaced. from l,the 69 sidewall so that the supportsfor the guides can project beyond rthe rollers, shoes or guidesfor anchorage or retention of the same thereon without the supports and the anchorage engaging the trackside or back15. g l

As shown in the last two before mentioned applications the head structure includes` afront vertical wall 14 which is interrupted intermediate its ends and terminates in a forwardly and upwardly curved socket forming portion 19. The zo top 20 of the socket is directed inwardly anddownwardly and isformedby a separate strap that includes a curved portion 21 and a'straight portion 22, the samelying parallel to the portion-14 and terminating` as at 23 short of engagement with'the upwardly and rearwardly directed` grooved portion of the head structure forming an opening therebetween forthe passage of certain" of the guidev members which as before` stated, may be in the form of shoes, rollers or '80 slides. The body portion 10 ofthe head struc,- ture includes transverse portions ,2g that are rigid with the head structure and are struckv therefrom as at 25 and the same are spotwelded or' otherwise secured to the vertical strap 122. The grooved portion of the trackway, shown in Fig. 2, is continued throughout the length of the curves 11 and 12 and thecurve 11 terminates in an inwardly directed portion 26 that serves as a stop preventing the folded doors from mov- Platelo is apertured as at 27 and supports'a pivot 28 which supports an arm 29 Ythat isnrigid n with a combination track and switch having-the` depending portion 30 and the upper portion 31.

Normally thismember is positioned so'thatthe, 100

guide member bearing upon portion 12 will `pass -beneath the lower end of the member 3,0 andV travel along the portion 11 and will then engage the portion 31 to tilt the switch track into the full line position shown so that the second guide vmember passing along section 12will engage the end of themember 30 andride Vuponthe inside ofthe member 30 in the continued upward movement of the second guide member.

As shown'in Fig; 1, the back portion of 'the no f vertical portion of the track is relieved and there the inclination 36 which is merged with av'portion As shown by the dotted lines in Fig. 1, :Whena different size door, that is a door of die'rent width, is employed, membersfof slightly-.different formation and dimensions are substitutedk for those previously set forth. The head struc-V ture includes an additional'opning 127, in which is then mounted the pivot 123, supporting arm 129, in turn supporting the switch track member 131 and 130. As shown in Fig. l, the switch track` member 130 includes an extension 1300L.

When the substituted switch track is mounted upon the head structure, there is substituted for the'member 33,\anoth`er member of similar formation but having a different forward'outline,

' to wit, the same isprovided with the upwardly and V'forwardly inclined portion 136l and an inwardly and upwardly curved portion 137.r` These substituted parts are utilized together and replace the beforementioned parts 36 and 37 which are also used together.

The head structure, as shown clearly in Fig. 1, has outlined from ita plurality of pairs of ears asf'atiiQ, 41, I42 and 43. Eachof these is apertured as vat 44 and the vhead is apertured as at 45 and 45, the latter beingacontinuations of the severances 42 and 41, and the'samebeing'connected together so thatwhen the ears outlined at fil), 41,- 42 and 43k .are turnedl outwardly and at180 degrees to the portions 24, they forma Yfour bearing support for the pulley shaft, and all the holes 440i? the four ears are in alignment. Also with this formation,th`ere is formed anvenlarged opening that is shown dotted as at and-through which the'pulley when mounted projects. This pulley accommodates the cable or other ex-ible connection between'the coun'- terbalancing means andthe lower Y'door section.

Reference will now be had to Figs. 3 and 4. this lmodified vform of the invention, the sheet metal headi structure l0 has nformed integral therewith the portion 33 and it is also formed with having an outline as indicated at 137, all of the aforesaid being integral. Theportion33, or more specifically that portion included and defined by theV portions 35, 37 and l37-,is suitably apertured and when a lower socket, such as indicated at' 37, must be employed, then the additional member 250 is'associated therewith and secured as at 2751 so that the vertical portion 235 forms an extension downwardly of the portion`35'and the curvedV portion 237 merges with the portion 36 and is the equivalent of the portionfindicated at 37 `in Fig. 1f Preferably the aforesaid head structure is of sheet metal and of suitable thicknesspf stock for' the `Ipurpose set forth. The two interchangeable inserts maybe castings or stampings'. The supplemental' members shofwn vin Figs. 3 and 4 is preferably a casting. ,y Y
