TRANSOM-OPERATOR.

Specification of Letters Patent.

Patented Apr. 14., 1914;.

Application filed March 13, 1913. Serial No. 753,953.

To all whom it may concern:

Be it known that I, LOUIS B. SMYsnR, a citizen of the United States, residing at New BritaimHartford county, State of Connecticut, have invented certain new and useful Improvements in Transom Operators, of which the following is a full, clear, and exact description.

This invention relates to operating means for transoins and allied closures, and is designed to provide a device of this character with a relative arrangement of parts affording greatest operating power at the period of greatest load; toprovide an assembled operating unit ready for attachment; and

further, to provide improved features of construction in connectlon with the operating mechanism. These and other advan tages will be more fully described in the following detailed specification taken in connection with the accompanying drawings forming part thereof and illustrating a preferable embodiment of the invention.

In these drawings: Figure 1 is a fragmentary view in side elevation from the outer face of a door jamb showing the operating mechanism applied thereto and connected to a transom. Fig. 2 is a front elevation, partly in section, of the parts shown in Fig. 1. Fig. 3 is a fragmentary view in side elevation 011 an enlarged scale, of the parts shown in Fig. 1 with the transom and its operating parts in closed position. Figs. 4: to 7 inclusive are views on an enlarged scale of details of construction of the operating mechanism. Fig. 8 is a view in elevation and on an enlarged scale of the transom operating bar and gear case. Fig. 9 is an end elevation of the same partly in section. Fig. 10 is a view in elevation of the transom operating bar and gear case, the latter broken away and in section to disclose the interior arrangement. Figs. 11 and 12 are views of details of construction of the gearing. Fig. 13 is a sectional view through a door casing illustrating the position of the frame and gear casing therein.

As I have before stated, one of the objects of the present invention is to provide a unit construction whereby the operating parts may be applied as an assembled unit. These operating parts, or such as are capable of assembly prior to the application thereof to a door casing, are to be mounted on a frame or carrier preferably 111 the form of a metal bar or plate 1 extending vertically of the door edge and applied to the outer face of the door jamb 2, or to that face which is non-adjacent the door.

3 designates a transom of the bottom lunged type, the hinging means being designated at a. The end face of this transom at a point intermediate its top and bottom is provided with a plate 5 fixedly secured thereto and provided with a longitudinal slot 6.

7 designates a transom arm having a stud 8 at its upper end seating in the slot 6 of the transom'plate. The lower end of -this arm is provided with two or more segmental slots 9 therein. This arm 7 is located on the transom and door side of the jamb 2. On the opposite or outside face of the jamb is located a second arm 10 having a stud 11 secured to one end and carrying an anti-friction roller 12, and at its opposite end provided with segmental slots 13. The frame 1. and jamb 2 are bored to provide an opening through which a connecting stud 14 for these two arms 7 and 10 may extend, this stud being provided at its opposite ends with segmental. projections 15 designed to fit into the segmental apertures 9 and 13 in these arms to rigidly connect them together. The arms are locked by means of a screw extending through a longitudinal bore in the stud and threaded into the arm 10 between its slots 18. The head of the screw seats in a countersunk recess in the arm 7 between its slots 9. These arms are connected at an acute angle and together form a lever designed, when force is applied to the free end of the arm 10 thereof, to move the transom 3 into and out of closed position. These operating parts for the transom which I have described are separate from the frame 1 carrying the operating mechanism and are attached to the transom independently thereof, the door jamb, of course, being provided with a bore through which the stud 14 extends, and a bushing 16 being preferably provided in this bore. The frame 1 is provided with an aperture therein through which the bushing and stud may extend, the length of these parts being such as to space the face of the arm 10 from the face of the frame 1.

The operating unit,'of which the plate 1 forms the bed or frame, is designed as follows: A plurality of spaced and alined brackets 17 are provided, these brackets being rigidly secured to the frame 1 by any suitable means and being apertured to guide therethrough an operating bar 18 extending vertically of the door jamb and longitudinally of the frame 1. Adjacent its upper end, this operating bar has fixedly attached thereto a sleeve 19. Adjacent its upper end, the frame 1 carries a bell-crank lever 20, one end being pivotally mounted on said frame by suitable means as by a stove bolt 21, or similar means, which may extend through an aperture formed in the frame 1 and through a bore in the door jamb 2, thus serving also to connect the upper end of the frame to the door j amb, although other or additional means may be employed to effect this result, if desired. 22 designates a link pivotally connecting the other end of the bell-crank to the fixed sleeve 19 of the operating bar 18. This bell-crank is designed to operate the transom through the arm 10 connected thereto. As shown, the bell crank is provided with an elongated slot 23 therein, this slot extending between the pivot point 21 of the bell-crank and the apex of its angle. A strengthening boss 24: is preferably formed about this slot. The anti-friction roller 12 of the arm 10 is designed to rest within the slot, the arm 10 being mounted to position its roller at the lower end of this slot when the transom is in its lowered position so as to afford maximum leverage through the bell-crank lever 20 to raise the transom to closed from opened position, this maximum leverage being available at the time of maximum load or when the transom has been opened.

It will be evident that by moving the operating bar upwardly and downwardly, the bell-crank 20 will be swung on its pivot to swing the transom to and from closed position through the connecting lever formed by the arms 7 and 10 and pivoted eccentrically relative to the bell-crank so that the movement of the bell-crank on its pivot will swing this lever to effect the result named. In order to move this operating bar 18, its lower end is formed as a rack 25 and a gear casing 26 is provided through which this rack end of the bar is guided, this gear case being secured to the frame 1 by means of stove bolts 27 which extend through apertures formed in the frame 1 and through bores formed in the door jamb 2, and serve also to connect the lower end of the frame 1 to the jamb. These bolts extend out of and are accessible from the door side of the jamb, as will be clearly seen from the drawings. The gear casing is provided with a cover 28 including gear housings 29 and 30. A rack-engaging gear wheel 31 is seated in the base of the gear casing and is provided with an integral sleeve 32 and with bosses 33 formed at opposite ends of ing its head seated in a recess formed in the side of the housing and having a threaded end threaded into the housing 29 and engaged at its projecting end by a nut 38 by means of which it is held stationary within the gear housing. This bolt serves as a spindle on which is journaled a compound gear element comprising a sleeve 39 having a worm 40 cut thereon positioned to engage with the annular worm gear at of the rackengaging gear element heretofore described. At its oppositeend', the sleeve 39 is provided with a spur gear wheel 41 positioned in the lower portion of the housing 30.

The gear housing 30 is separatefrom the" housing 29 and cover 28 of the gear casing and is held thereto by means of the bolt 37.

and by the provision of'an outward ofiset 42 in the cover 28, which offset part 1s'provided with a toothed upper edgeengaging with the toothed lower edge 13 of the hous ing 30. Within the upper portion of the housing 30 is journaled a second gear wheel 14 in mesh with the gear &1 in thelower portion of the casing 30, this gear 4 1 being suitably journaled within the housing 30 and having a hub 45 extending through a bore in the casing 30 and provided with'a squared aperture 46'therein.

Referring specifically to Fig. 13 of the drawings, it will be seen that the frame 1 is mounted upon the inside of the door jamb and that the gear case and its housings rest against the adjacent buck 47 which may be recessed to receive these gear housings. The space between the buck and jamb. is, of course, covered by the usual strip of trim or molding 18. It is through the gear 1 1- that motion is transmitted to the rack-engaging gear wheel 31 and through the rack of the operating bar to the transom. The appearance of the attachment is improved if the operating handle, hereinafter described, which engages the squared aperture 46 of the hub 45, is centrally positioned with reference to the molding 4:8. This is possible by reason of the fact that the housing 30 may be vVhen the hub 45 has been properly positioned relatively to molding l8, the housing 30 is pushed in to engage its toothed edge 13 with the teeth of the offset 12, and the bolt 37 then screwed in and its nut tightened.

It is further desirable to provide means for lubricating the parts of the gearing which are not easily accessible. In the specific form of gearing disclosed herein, such parts will beparticularly the gear element 40 and 3-4, the lubricant being distributed from these elements" to the other gear elements. To this end I provide a borein the door jamb 2 in alinement with the boss 33 of gear 31 through which boss, gear and its sleeve 32 the lubricating aperture 35 extends, and insert into said bore in the boss 33, an oiling tube 49, to the outer end of which is secured a valve casing 50 having in its outer end a lubricant inlet opening 51 normally closed by a ball valve 52 pressed thereagainst by a coiled spring 53. The outer end of this valved inlet to the lubrieating tube is positioned at the door side of the jamb 2,"preferably slightly within the edge of the jamb so that access may be readily had thereto for the purposes of lubrieating the gearing.

The molding strip48 is, of course, provided with a'suitably located bore through which the spindle 54: of an operating handle I 55 extends, a suitable rose 56 being preferably provided and resting against the outer face of the molding 4:8. The inner end of the spindle 54 is squared and seats in the squared socket 46 of the hub of gear 14: so that when the handle is turned from the exterior, the worm gearing 34L40 is operated through gear. train 4H1, operating the rack and pinion gearing 2-5-81 to raise or lower the operating bar 18. All of the operating parts, except the transom arm 7 and operating handle 55, are concealed from view so that the appearance of the door or other casing is not marred.

While I have herein described the bellcrank 20 and its connections as for a bottom hinged transom, it will, of course, be obvious that the specific manner of connection may be modified to suit top and center hinged transoms, the same principles of operation being involved in each of these cases.

From the foregoing it will be obvious that th mechanism of the transom operator, except such parts as of necessity are directly connected to the transom itself, may be embodied in the form of an assembled unit mounted upon the frame or plate 1 ready for application to the jamb of a door. It will also be obvious that the bell-crank lever 20 and the relatively eccentric lever formed by the arms 7 and 10 are so constructed and arranged to afford maximum leverage to raise the transom from lowered position, and minimum leverage when the transom is in closed position. In opening the transom, it is not necessary to employ any great amount of leverage, as the opening action is usually aided by gravity. On closing the transom, however, the greatest load is encountered and I have so constructed and arranged the parts of my device that the maximum leverage is secured at the moment when it is most needed. It will also be evident that while the invention has been specifically described as applied to transoms, it is of general use in connection with various forms of hinged closures.

It should be understood that the arrangement of pin and slot connections shown may be reversed without departing from the spirit or scope of this invention, since the function of the pin and slot connections shown at 6-8 and also at 1123 is simply that of well-known compensating means and 1s used to permit that degree of independent movement required in the type of compound or differential lever action shown.

lVhile I have herein described and illustrated a specific embodiment of my invention, it should be understood that the same may be altered in detail and relative arrangement of parts within the spirit of the invention and the scope of the appended claims.

What I claim, therefore, and desire to se cure by Letters Patent is:
