GATE OPERATING AND LOCKING MECHANISM.

Application filed January 5, 1923. I Serial No. 610,829.

1 drawings.

This invention relates to certain improvements in gate operating and locking mechanisms and has relation more particularly to a mechanism of this general character especially designed and adapted for use in connection with double doors and it is an object of the invention to provide such a mechanism means whereby the doors may be caused to operate to move in unison together with means for effectively holding or locking said doors when in either open or closedposition. I

Another object of the invention is to provide a novel and'improved device of this general character comprising a carriage operatively engaged with the doors whereby the doors are caused to move in unison together with means associated with the-carriage for holding the doors when in either open or closed position.

Another object of the invention is to provide a novel and improved mechanism of this general character embodying means for causinga plurality of doors to movein unison together with additional means -for locking the doors when in closed position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved gate operating and locking mechanism whereby certain important advantages are attained and the device rendered simpler. less expensive and otherwise more convenientand advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that myinvention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a vertical sectional view with parts in elevation illustrating a mechanism having novel and improvedconstructed in accordance with an embodiment of my invention, the single door shown being in closed position;

Figure 2 is a fragmentary view partly in elevation and partly in section of the care riageand track as illustrated in Figure 1, ea said view being reverse to what is illustrated in Fi ure 1;

Figure 3 1s a detail sectional view taken substantially onthe line 33 of Figure 1 looking in the direction of the arrow; ca

Figure 4 is a view partly in top plan and partly in horizontal section illustrating my improved mechanism with the associated doors in closed position, a second position of the doors being diagrammatically indicated .by broken lines;

Figure 5-is a detail sectional View taken substantially on the line 5-5 of Figure 1 looking in the direction of the arrow;

Figure 6 is an enlarged fragmentary view partly in elevation and partly in section illustrating the locking mechanism as herein comprised, v

As disclosed in the accompanying drawings, D denotes a pair of swinging doors of a type particularly adapted for use in connection with garages or kindred structures and a detailed construction of which forms no particular part of my present invention. Supported inwardly of the doors as by the rafters 1 orthe like is a track-way T of desired length, said trackway being herein disclosed as held in applied position by the brackets 2. l

The track-way T is substantially H-form in cross section and traveling along said track-way is a carriage C provided adjacent its opposite ends with the transversely spaced flanged wheel 3 directly engaging the track-way. The carriage C also embodies as the side plates tarranged outwardly of the track-way T and extending therebelow. The lower portions of the side plates 4 have interposed therebetween and secured .thereto, as by the rivets 5 or the like the plate (5, 10 said plate underlying the track-way T.

Extending outwardly and laterally from each of the side plates dis a pair of vertially spaced arms7 between which is pivotally engaged the flattened head 8 opcratively 106 engaged with the end portion of a tubular member 9. The member 9 is of desired length and has its opposite end portion provided with a second flattened head 10 which extends between and pivotal ly engages with a vertically spaced pair of arms .11 carried by a bracket 12, said bracket 12 being su tably anchored to the upper portion of a door D at a point in relatively close proximity to its outer or free vertical margin.

The rods 9 provide means whereby the c ar-- riage C causes both of the doors 1) to swing in unison into either open or closed position and irrespective of. which of the two doors may be subjected to the requisite push or pull. Freely 0r loosely, engaged with one of the axles 14 of the carriage is an end portion of a vertically swinging arm 15 the outer or free end portion of which terminating in a depending lug or flange 16. The arm 15, as is clearly illustrated in Figure 1 overlles the second axle 14 of the carriage C to positively limit the downward swinging movement ofsaid arm 15,

When the doors D are in closed position as illustrated in Figures 1 and 3 the lug or. flange 16 seats within a groove o'r recess 17 formed in the upper face of a block 18. The upper surface of the block 18 before and aft of the recess or notch 17 is disposed; on an upward and inward incline so that as .the carriage passes over the block 18 the lug or flange 16 of the arm 15 will be readily received within the recess or notch 17. When the lug or flange 16 is so engaged within the notch or recess 17 the doors D are held against outward or opening move-- ment.

When the doors Dare at the limit of their outward or openingmovement the lug or flange 16 of the arm 15 engaged within the recess or notch 19 produced in the upper surface of a block 20, said uppensurface of the block 18 before and aft of the notch or' recess 19 beingalso disposed on an upwardor inward incline to facilitate the entrance of the lug or flange 16 within said notch or recess.

Underlying the block'20 is a block 21 herein disclosed as secured to the block 20 by the coacting bolts and nuts 22. The bolts being disposed through a suitably positioned elongated slot 23 formed in the web of the track-way T. The slot 23 provides means whereby the blocks 20 and 21 may be adjusted lengthwise of the track-way T as the necessities of practice may require.

The block 21 is provided with a depending and inwardly facing shoulder 24 with which. the plate 6 of the carriage C is adapted to contact and whereby the extent of outward or openin movement of the doors D is positively imited.

The block 18, hereinbefore referred to, is held to the web of the track-way T by the coacting bolts and nuts'25, the bolts being also disposed through a suitably positioned slot 23 whereby the position of the block 18 may be adjusted lengthwise of the trackway T as desired.

It is preferred in producing the track-way T to have a plurality of slots 23 produced in the web at predetermined points spaced longitudinally thereof so that in applying my improved mechanism the blocks 18, 20 and 21 may be readily and convenientlylocated upon the track-way T as desired.

The arm 15 together with the lug or flange 6 carried thereby normally swings downwardly by gravity. Depending from one of the pipes 9 adjacent an associated head 8 is a pair of spaced arms 26 between which is pivotally engaged as at 27 the wheel'portion of a bell crank lever L. One arm 28 of'the lever'L underlies a vertically disposed rod 29. having free sliding movement through a tubular bolt 30,- said bolt 30 also serving as a pivot between a head 8 and a pair of arms 7. This rod also underlies an outstanding and laterally disposed wing 31 carried by the arm 15 at a point between the axles or shafts 14 of the carriage C. Upon upward swinging movement of the arm 28 of the lever L the rod 29 may also be forced upward and by contact of the arm 29 with the asso ciated wing 31 the arm 15 will be raised sufliciently to disengage or free the lug or flan e 16 from either a block 18 or a block 20 so that the doors D will be to swing into open'or closed position,

The'second arm 32 of the bell crank lever L extends upwardly within the adjacent pipe 9 through a suitably positioned slot 33 provided in the wall of said pipe and the inserted end portion of the arm 32 is operatively engaged with a rod 34 extending through the pipe 9 and also operatively engaged with an inserted end portion of an upstanding arm 35 of a second bell crank lever B. This lever B has its wheel portion pivotally supported as at 36 between a pair of arms 37 depending from the outer end portion ofthe pipe 9 and the second arm 38 bf the lever B is disposed 'in a direction toward the door D.

The outer end portion of the arm 38 is operatively engaged as at 39 through the instrumentality of a chain or other flexible means with the upper end portion of a vertically disposed rod 40. This rod 40 is preferably sectional with its adjacent end portions coupled by a turn-buckle 41 so that the rod 40 may be lengthened or shortened as the occasions of practice may require when applying my improved mechanism and whereby the mechanism is maintained substantially free of rattle and without undue lost motion.

The lower portion of the rod 40 is pro vided with a bar 42. This bar 42 is slidably disposed within a casing 43 through the top thereof and the inserted end portion of this bar 42 is operatively engaged with a rock member 44. The arm 42 within the casing 43 is )rovided with a laterally directed arm 45 which operatively engages through the medium of the rigid plate 46 with the end portion of a rock lever 47. The opposite end portion of the lever 47 is operatively en gaged with a second bar 48 which has free sliding movement through the lower portion of the caslng 43 and the outer or lower end portion of said rod 48 is operatively engaged with the upper end portion of a rod 49. This rod 49 is also sectional and has the opposed end portions of its sections coupled by the turn-buckle 50 for the same purposes as hereinbefore set' forth with respect to the turn-buckle 41. The lower end portion of the rod 49 is operatively engaged asat- 51 with the latch 52. This latch 52, when the doors D are in their full closed position, engages a keeper 53 provided in the floor of the garage or other structurewhereby the doors D-are further held in closed position.

Disposed through the casing 43 and extending beyond the opposite sides of the associated-doors D is a spindle 54, the extended or exterior portions of said spindle having suitably afiixed thereto the operating members 55, whereby requisite turning or rocking movement may be imparted to the spindle 54 outside of the garage or other structure or from Within. Carried by the spindle 54 within the casing 43 is'a cam' member 56 which, upon requisite rocking movement of thespindle 54 serves to impart the desired rocking movement to the rock member 44 and which movement results in a simultaneous inward pull being interposed upon the bars 42 and 48 resulting in retraction of the latch 52 and upward swinging movement of the arm 28 of the lever L to free the flange or lug 16 from either the block 18 or 21. Under these conditions the doors are then free to be moved in either open or closed position,

With the doors D in either open or closed position it is of advantage to ositivelylock the same in such position and for this purpose I shall provide within the casing 43 a key actuated bolt 57 which interlocks with the bar 48 when said bar has been moved inwardly of the casing 43'.

From the foregoing description it is thought to be obvious that a gate operating and locking mechanism constructed in ac cordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated,.and it will also be obvious that m'y invention is susceptible of some change andmodification without .departing from the principles and spirit there of and for this reason I do. not wish to be understood aslimiting myself to the precise arrangement and formation of the several parts hereln shown 1n carrying out my 111- vention in practice except as hereinafter claimed.
