JOSEPH W. MILLER, OF SUSQUEHANNA v'lWNSI-IIP,

PENNSYLVANIA, AssIGNoR or ONE-NALF TO HOWARD L. ARNOLD, OF SUSQUEHANNA TOWNSHIP, PENNSYL- VANIA.

Application filed March 1, 1915. Serial No. 11,297.

T 0 all 'whom t 'mag/.concern Be it known thatf I, Josnrii W. MILLER, a citizen of the United States, residing at Susquehannatownship, in the State of Pennsylvania, have invented certain new and useful Improvements in Door-Operating Mechanism; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the 4art to which it appertains to make and use the same. i

The invention relates to improvements in door operating mechanism. u

The object of the present invention is to improve ythe construction of vdoor operating devices and to provide a simple, inexpensive and practical door operating device adapted toenable a garage door or similar closure to be readily opened and closed by a chauffeur entering or leaving the garage.

A further object of the invention is to arrange the door operating means in con-I venient position with relation to the door and with one of the. door operating levers close to the side of a machine while the latter is straddling the other lever. j

The invention also has for its object to provide latch mechanism automatically operated to release the door in the opening movement of the latter and to engage and secure the door when the latter is closed.

Vith these and other objects in view the invention consists in the construction and novel combination and varrangement of parts hereinafter fully described, illuse trated in the accompanying drawings and pointed out in the claims hereto appended, it being' understood that various changes in the form, proportion and minor details of construction may be resorted to without de-` parting from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure l is a perspective view of a portion of a garage provided with door operating mechanism constructed in accordance with this invention, the door being closed, Fig. 2 is a vertical longitudinal sectional view of the same, the door being open, Fig. 3 is a reverse plan view ofv the door operating mechanism, Fig. 4 is a transverse sectional view, Fig. 5 vis a detail perspective view of the latch mechanism for securing the door in its closed position, Fig. 6 is a detail sectional view illustrating the manspecification of Letters Patent.

DOOR-OPERATIN G MECHANISM.

ner of mounting the latch arm on the verticlosure. The door 2 which is hinged at 3 is provided at the bottom adjacent to its hinged edge with a projecting arm 4 provided with an attaching portion 15 and connectevdby a link '6 with an approximately L-shaped arm 7 of an angle lever 8. p

The attaching portion 5 of the arm 4 is lsuitably secured to the inner face of the door and a pair of links 6 is'prefer'ably employed and is secured by pivot bolts 9 and 10 or other suitable fastening means to the arms 4 and 7. rlhe angle lever 8, which is fulcrumed at its angle at 11 on a suitable pivot is mounted beneath the floorv l2 of the garage and the said L-shaped arms extend upwardly through an opening l13 in the said floor.` The other arm 14 of the bell crank or angle lever 8 is connected by links 15 to an arm 16 of a transverse lever 17 fulcrumed intermediate of its ends on a suitable pivot bolt 18 and located beneath a platform or 4 of the drawings. The arm '21 of the transverse lever is arranged at an angle to the arm 16 and is connected at its outer terminal with a pair of dooropening and closing levers 22 and v23 by links or vbars 24' and 25. The door opening and closing levers 22 and 23 are fulcrumed intermediater of their ends at 26 and 27 on the extension or platform 19 and ythey extend above and below the same, the lower armsJ of the levers 22 and 23 beingV connected to the said links or bars 24 and 25. The link or bar 24 which. is approximately straight extends from the arm 21 of the transverse lever to the door open- -ing lever 22 and the other link or bar 25 is the door closing lever to the link 2li and is secured to the same at 28 by a bolt or suitable fastening device. The levers 22 and 23 which are equipped at their upper arms with pedals or foot plates 29 and 30 have their said upper arms arranged at a slight angle to their lower arms which are disposed in parallelism and which also move in unison.

When the door is open as illustrated in Fig. 2 of the drawings, the foot lever or treadle 29 is depressed and arranged close to the platform or extension 19 while the other foot lever or treadle is elevatedand is located in an approximately vertical position. Suiiicient space is provided between the foot plate or treadle 29 at the garage to f allow for the opening of the door when the machine is adjacent to the foot lever 22.

When the door is closed as shown in Fig. 1 of the drawings the outer door closing lever is depressed and the foot plate or pedal 30 thereof is contiguous to the platform or extension 19 while the door opening lever has its foot plate or pedal elevated. The

lever 23 is located a sufficient distance from the garage to enable a machine leaving the garage to stop with its front portion at the foot lever 23 and at the same time be clear of the door so as not to interfere with the closing movement thereof.

The door is locked in its closed position by latch mechanism comprising a vertical rock shaft 31 j ournaled in suitable bearings at one side of the door opening 32 of the garage and provided at its upper end with a latch arm 33 and having an arm 34 extending from its lower end and connected with the transverse lever by a link 35. The link 35 is pivoted to the arm 21 adjacent to the link 24 as clearly shown in Fig. 3 of the drawings. The latch arm 33 Vwhich has a hooked shaped outer portion 36 for engaging the door extends through a slot 37 of a face plate 38 and it is provided at its inner end with an opening 39 of rectangular or other polygonal shape in which is arranged a polygonal portion 40of the rock shaft 31. The latch arm has a limited movement independent of the rock shaft 31 and is connected with a coiled spring 41 secured at one end to a fixed portionof the garage and connected at its other end to the said latch arms. The coiled spring L11 is adapted to maintain the latch arm rmly in engagement with the door 2 and the limited independent movement of the latch arm permits the door to close after the latch arm is in position for engaging the door. rlhe curved hook shaped portion 86 at the outer end of the latch arm presents a rounded surface to the edge of the door and enables the latter to swing the arm outwardly or rearwardly a sufficient distance to pass the engaging portion 36 which is automatically carried into engagement with the door by the spring 41 after the door has passed the bill of the hook-shaped portion 36. By this construction a door is automatically unlocked and opened when the lever 22 is operated and when the lever 23 is operated the door is closed and locked.

l/Vhat is claimed is 1. Door operating mechanism of the class described including a main transverse lever, an angle or bell crank lever having an approximately L-shaped arm, means for connecting the other arm of the angle or bell crank lever with one of the arms of the main lever, a link for connecting the L-shaped arm with a door, and door opening and closing levers connected with the main levers, said door opening levers being spaced apart laterally and located at different distances from the door at the same side thereof.

2. Door operating mechanism including operating mechanism connected with and adapted to open and close a door, a substantially vertical rock shaft adjacent to the free edge of the door connected with the said mechanism, a latch arm mounted on the rock shaft independently of the door and arranged to engage the free edge of the door, and yieldable means connectedfwith the latch arm for urging the same toward the door.

3. Door operating mechanism of the class described including door opening and closing means, a substantially vertical rock shaft having an arm connected with the said means, a latch arm carried by the rock shaft and having a limited movement independently thereof and a spring for urging the latch arm toward the door.

4l. Door operating mechanism of the class described including door opening and closing means, a substantially vertical rock shaft connected with the said means and provided with a polygonal portion, a latch arm having an opening,` receiving the polygonal portion of the rock shaft and having a limited movement independently of the said rock shaft, and a coiled spring connected with the latch arm and arranged to urge the same toward the door.

1n testimony whereof l affix my signature in presence of two witnesses.
