Applicatie filed april 18, 1913. serial No. 762,047.

To aZ tti/Um t may concern Be it knownth'at JAMES T. WGCAE,

-a citizen of the United States of America,

and a resident of the borough of Manhattan, city, county, and State of New York, havel invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.

My invention relates to door hangers, and

especially to hangers for that type of doors which are composed of two parts movable relatively to each other and conjoin'tly closing a door-opening. In this type of doors,= it has been heretofore proposed to connect the rider bars of the separate halves of the door together through the instrumentality of a pinion mounted upon the rider bar of one half and gearing into a rack upon the rider far of the other half, and also into a rack fixed in 'the door opening whereby t'he movement of the door half on which the pinion is mounted produces a movement of the other half of the door, of double the speed, or vice versa. In such a construction it has been found difficult to preserve under the conditions of settlement and Wear, and under the necessary adjustments which must be made of the rider bars vertically, the proper engagement of the pinion with the two racks, and for the purpose of over-coming these defects my invention consists in mounting the pinion upon its rider bar, not on a fixed pivot, as has heretofore been the case', but in such a manner that the pinion is capable of movement in respect to the usual adjustments ofl rider bars, thereby permitting a wider range of adjustment of the door halves and the rider bars thereof without disturbing the proper meshing of the pinion than is possible with the present construction.

Referring to thel accompanying drawings in which corresponding parts are designated by corresponding marks of reference, Figure 1 is a perspective View ofa structure ernbodying my invention. Fig. 2 is a vertical cross section thereof, and Fig. 3 is a diagrammatic side elevation.

The two halves A and Aofythe door are' of the usual construction and each is hungfrom a rider bar B, B', respectively, which 'rijder bars are of a like construction with each other, but are reverselv arranged.

Above the door opening is the angle bracket C, which carries the stationary tracks D, D located side by side, balls E, E contaned 1n suitable retaining plates F, F, being located between each rider bar and its corre` sponding stationary track. Each`ridcr bar and stationary track and balls and retaining plates therefor, are by preference similar to the construction shown and described in Patent No. 1,038,502, granted to me September 10, 1912. the structure may be said to comprise therefore, a plurality of stationary tracks located side by side, each track supporting through the intermediary of the balls, a rider bar on vwhich a corresponding doorhalf" is mounted. i

sthe parts above referred to are identical on the opposite sides of the center line of the door, I have used the reference numerals and exponents to distinguish between the parts correspondingI to the two doorhalves,

Each of the stationary tracks l) and D is adjustably carried from the bracket C by means of the bolt and nut structures H. The rider bar B has secured thereto ay rack J having teeth on its upper surface and located by preferencemidway of the two door halves, such rack being carried on a skirt K depending from the rider, while directly above the rack J, but separated therefrom by a suitable distance, is the corresponding rack L, the teeth of which face downwardly, and which is 'carried from, and adjustable vertically on the bracket C by the bolt' and nut structure M. Between the racks J and L is located the pinion N, meshing with both of such racks. and connected to the rider bar B. As stated this connection is made in Such a manner, that the pinion is capable of vertical movement in respect to such rider bar, and this I prefer to accomplish by mounting the pinion on a studQvcarried on one end of a link P, the opposite end of which is 'pivoted to the rider bar B so that such pinion is capable of vertical movement in respect to the rider bar. 'By this construction,

it will be noted that with the fixed track D properly adjusted, and the section A properly adjusted in respect to its rider B', any desired adjustment may be made of the door section A Without destroying the proper vintermesh of the pinion N with the two racks As far as above stated, n

J and L provided that with each adjustment of the door A, and consequent change of position of' the rack J, `he rack L be ad'- justed to maintain it at the tixed uniform distance from the rack J. This much simplities the mounting of the doors ot the charactcr referred to.

it is obvious that with the `general construction above described, a movement of the door-halt A through a given distance in the direction of the arrows l and 2 Fig. 3, will move the pivot of the pinion through the same distance and will give a movement twice as great to the racl J secured to the halt' A ot the door, whereby. ,he door-halves u'ill be projected at a proper relative speed for each to close its respective share ot the door-opening when the part B shall have reached its limit ot movement and upon a movement ot the door-halves in the opposite direction to that shown b v the arrows in Fig. l), they Will simultaneously each reach their open position.

Having thus described my invention, what I claim and desire to secure by Letters Patent is l rEhe combination With a plurality of fixed tracks, ot a rider bar, and a travelingT door part associated With each track; a tixefl rack, a rack movable With one of the door parts; and a pinion mounted on another ot the door parts`r but movable relativelg7 thereto transverse to the line otV movement et the door parts. and engaging' the said racks.

2. The combination ivith a plurality ot fixed tracks. ot a rider bar, and a traveling door part associated With each track; a iXed racln a rack movable with one ot the door parts; and a pinion engaging both of the said racks, and a linlr connection between the pinion and the other door part.

n testimony ivhereot il have. hereunto signed my name in the presence ot tivo ivit` nesses.
