ANTHONY r. MERQNEK, or POLONIA, W sconsin.

Application filed June 5, 1924. Serial No. 718,124.

To all whom it may concern.

Be it known that I, ANTHONY F. MER- oNnK, a citizen of theUmted States, residing at Polonia. in the county of Portage and State of Wisconsin, have invented certain new and useful Improvements in Manually-Operated liltechanisms for Operating and Securing Swinging Doors; and I do declare the following to be a full, clear, and exact description of the invention; such as will enable others skilled inthe art to which it appertains to make and use the same. 1

This invention relates to an improved manually operated means for opening and closing swinging doors and releasably securing these doors in either an open or a closed position, the device being so constructed that a portion of the mechanism may constitute a handle by means of which the doors may be opened and closed and a portion of the device constituting a latch for releasably securing the doors in either the open or the closed position.

Another object of the invention is to so construct this structure that a pair of swinging doors may be simultaneouslymoved to either an open or a closed position when the handle portion of the device carried by one of the doors is grasped and turned to release the latch and the door carrying the handle moved to either the open or the closed position.

Another object of the invention is to provide a device which may be operated from either within or outside the garage.

Another object of the invention is to provide a structure of the character described which will be simple in construction and easy to operate and not liable toreadily get out of order.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view showing the garage and door operating mechanism in top plan with the garage shown in section and the doors shown closed.

Figure 2 is a view similar to Fig. 1 show 'ing the doors open.

Figure 3 is a vertical sectional view through the garage with the door-operating mechanism shownin side elevation and the doors secured in the closed position.

Figure 4:is a view similar to Fig. 3 showing the handle elements turned to move the latches to the releasing position and'permit opening of the doors.

Figure 5 1s a bottom'plan view showing the latch in position to secure the doors when open.

. This garage is indicatedrin general by the letter G and will, be provided with doors .1) vhingedly mounted so that: they may be swung outwardly from the closed position of Fig. 1 to the open position of Fig. 2. This is a conventional construction of garage and 1t Wlll be understood that the garage and doors may be formed of any suitable material.

A bar 1 which may be termed a track bar or track element extends longitudinally in the garage and has its end portions secured to the front and rear walls thereof above the level of the doors. It will thus be seen that this bar willbe positioned at a sutficient height so that it will not inter fere with an automobile entering or leaving the garage. This trackbar 1 has been provided with lugs 2 and 8 as shown in Figs. 3 and 4 for engagement by the catch arms 4 and 4t of the latch 4 which is pivotally carried by a carriage 5 positioned beneath the track bar and provided with side flanges 6 which overlap the side portions of the track bar and thus slidably mount the carriage.

mediate its length with a crank arm 8 by means of which it may be moved to an inoperative position. It will be readily seen that when the latch is rocked in one direction, the arms P and 4t will be swung against the action of the spring 9 which is positionedabout the pin 7 and has its ends engaging the arms of the latch.

The handles 12 and 13 are rotatably mounted by means of a bolt 14 which extends through one of the doors and it will thus be seen that when either of the handles is grasped andturned, the other handle will turn with it. The handle 12 is provided with an extension 15 having an opening formed therein so that a lock 16 may be passed through the opening of the extension 15 and through a similar opening formed in a bracket 17 to lock the handles against turning and thus prevent un-authorized opening of the doors. A plunger latch 18 is slidably mounted in a bracket The latch is pivotally mounted by means of a pin 7, and is provided inter-v avardly from a draw-bar25, the outer end ot'which is connected with the handle-carrying door by means of a bracket 26. i A similar draw-bar 27 is pivotally connected with "the other door-by means off a bracket 28 and ilar connection :22. closed and when 1n ithls position, the latch these two draw-bars have their inner ends loosely connected with the carriage by means of the pivot pin 7'. An abutment ear 29 extends from the bar 25 to engage the latch arm 1- and limit pivotal movement thereof by the spring 9. The bell-crank lever '23 extends in a vertical plane and has its upper arm connected with the crank arm S of the latch I l by means of a wire, light chain or other ,similar I connection '30 and has its horizontallydisposed 'arm connected with the handle 13 at the opposite side thereof from the flexible connect on 22 by means of. a similarconnection 3-1. Therefore, when the handle is turned to the position shown in i, the latch 4% will be swung to move the (latch arm 4 out of engagement with the lug 3 r the arm 4 out of engagement with the lug '2 according :to whether doors are open or closed.

han thisstructure is'applied to a garage, the track bar will extend longitudinally in thelgarage and the bars 25 and 27 connect ed with the doors. QThe handles will be put in place and the handle 13 connected ith the bell-crank lever '23 by :means of the flexible connection ill and then connected with the plunger latch of the garage door ibyi 'means oi the chain or other -sim- The doors can then be arm 4- will engage the' lug 8 and secure the doors in the closed position. It the operator is standing outside'the garage, the

"padlock '16 can then be put in placeand the handles cannot be turned to release thedoors until the padlock is removed. WVhen' the padlock is removed, the handle 12 can be turned andas this handle is turned,-the handle 13, will turn with it thus drawing .upon the flexible connections 22 and 31 to move the latch 18 to a releasing position and turn 'the bell-crank lever 23 to draw upon the flexible connection 30 and thus rock the latch 4 upon the pin 7 to move the latch arin' i toa releasing position. With the latch in the releasing position, the han closed positions.

wards the doorway and at the same time,

cause the second door to be swung outwardly to the open position. Vhen the doors begin to open, the handles 12 and 13 may be permitted to return to the position shown in Figs. land 2 and the latch 4 will then be returned to the operative position so that when the doors have been opened the full extent, the latch arm 4 may 'en-' ga ge the lug 2 "and :the doors be securely held in the open position and prevented from blowing shut when not desired.

There has thus been provided manually operated means for opening and closing the doors of the garage and for releasably securing the doors in either the'open or the There has further been provided means in which the latches may be moved 'to a releasing posit-ion by means of handles which will serve as ordinary handles for tone of the doors.

I claim-1 1. Amechanism of't'heicharacter described comprising .a suitably mounted track bar, lugs projecting therefrom, a carriage slidahlymounted on said :track bar,-a latch pivotally mounted on said carriage, said latch 3 comprising oppositely extending catch arms bars pivotally connected at their inner ends with said carriage and at their outer ends witha pairot. doors, operatively connected handles disposed on opposite sides of one of said doors, and a latch releasing mecha- {and ;a laterally projecting crank arm, draw- 2 nism connected with one of said handles and with the crank arm-of said latch, whereby the turning o f said handle will actuate the latch for disengaging the catch arms thereof from the lugs on said trackbar.

2. Amechamsnroii the character described comprising a suitably mounted track bar,

pivotally mounted onjsaid carriage, said. latch comprising oppositely extending catch arms and a laterally projecting crank arm,

draw-bars pivotally connected at their inner ends with said carriage and at their outer ends with pair of doors, operatively connected 'hadles disposed on'oppositc sides of one of said doors, alat ch releasing mechanismcomprising a bell cr'ank lever pivotally mounted on one of said draw bars,a

flexible connection between one arm of said lever and one of sald handles, and a flexible connection between the other arm of said lever and' t-he crank arm of said latch.
