Application filed November 3, 1915. Serial No. 59,436.

To all whom it may concern:

Be it known that we, WILLIAM A. OLEEN and 0101* H. OLEEN, citizens of the United States, residing at Columbia Cit in the county of Columbia and State 0 Ore on, have invented certain new and useful mrovements in Door Opening and Closing KIechanisms, of which the following is a specification.

This invention has relation to certain new and useful improvements in door opening and closing mechanisms, and has for its primary object, the provision of improved mechanism which will be especially adapted for opening and closing the doors of a garage or the like.

The invention has for another object the provision of an improved door opening and closing mechanism of this character which may be readily operated to open or close the doors from either within the building or outside of thesame.

The invention has for another object the provision of improved mechanism of this character which will also include connecting means and door and latch operating means, all of which may be controlled by operation of the wheel operated members.

The invention has for a still further object, the provision of a door opening and closing mechanism of this character which will be extremely simple in construction and operation, as Well as highly eiiicient in use and composed of the Ininimum number of parts.

With the above and other objects in view, the invention resides in the novel construction, combination, and arrangement of parts as hereinafter set forth in the specification, pointed out in the claims, and shown in the drawings, in which- Figure 1 is a perspective view of the improved door opening and closing mechanism, showing the same connected with a pair of horizontally swinging doors of a garage or the like;

Fig. 2 is a plan view of the mechanism showing the doors and a portion of the frame for the same in section;

Fig. 3 is a horizontal sectional view of the upper portions of the doors and the frame for the same with the doors shown in open position in full lines and closed posi tion in dotted lines to illustrate the operation of the door connecting means;

Fig. 4: is a detail view showing the door latching means.

Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout 'the several views, 1 designates the reciprocating operating rod which has the operating link 3 mounted upon its inner end and within which is engaged the roller The roller 2 is secured to one corner of the inverted U-shaped wheel operated member 4' which has its lower ends pivoted, as shown at 5, to the floor 6 of the building a suitable distance from the door frame 7 and to one side of the hinged doors 8 and 9 mounted in said door frame 7. The wheel operated member 4 has a suitable roller 10 loosely mounted on its upper horizontalportion and said wheel operated member 1 is resiliently retained in its normal or upright position by the spring 11 secured to the floor 6 and having its arms 12 engaged against the opposite sides of the main portion of said wheel operated member 4.

The reciprocating operating rod 1 is preferably placed upon an incline and has its central portion engaged through the elongated slot 13 in the floor 6 beneath the door frame 7 and the outer ends of the reciprocating operating rod 1 has the link 14 formed thereon, within which is engaged the'roller .15 mounted upon the depending end 16 of 'similar chain 23 is connected with the outer collar 21. The chain 22 is extended around the curved face of the semi-circular casting 24 and secured to the outer vertical edge thereof as shown at 25, while the chain 22 is extended around the curved face of the casting 2i in the opposite direction and secured to the inner and vertical edge thereof as shown at 26. The casting 24 is secured to the lower inner corner of the door 8, as shown at 27, and a suitable opening 28 is formed in this corner of the door 8 to accommodate the chains 22 and 23.

A latch operating chain 29 has the diverging short connecting chains 30 and 31 connected with one end and also connected, respectively, with the chains 22 and 23. The latch operating chain 29 extends through a suitable guide 33 mounted'upon the inner face of the door 8 near the bottom thereof and the remaining end of the latch operating chain 29 is connected with the' niner upper corner of the pivoted latch plate 34. The latch plate 34: is pivoted to the inner face of the door 8 at the lower outer corner thereof, by a suitable pivot member 35 extended through the lower inner corner of said latch plate 34. The ivoted latch plate 34: is resiliently retained in its lowermost or operative position by means of a suitable spring 36 connected therewith and with the door 8 and operating against the chain 29. \Vhen in its lowermost or operative position, the pivoted latch plate 31 is adapted for engagement with the keeper 37 mounted upon the floor 6 to retain the dpors. 8 and 9 in closed position, as clearly shown in Figs. 2 and 4 of the drawings. The pivoted latch plate 34 is adapted to be guided in its movement upon its pivot 35 and limited in its movement by the guide pin projecting from the door 8 and engaged in the elongated and slightly curved guide slot 39 in the pivoted latch plate 3-1.

The doors 8 and 9 are connected at their upper ends by means of a connecting rod 40 which has one end pivoted in the small bracket 41 secured to the inner face of the door 8. while the opposite end of the connecting rod 40 is pivoted in the angula'rly extended bracket 42 secured upon the inner face of the door 9 and projecting rearwardly from the same. By referring to Fig. 3 of the drawings, it will be readily seen that as the door 8 is swung in either direction, the door 9 is compelled to swing with the same, thereby assuring proper opening and closing of the doors 8 and 9. Movement of the doors '8 and 9 outwardly is limited, however, by the chain 413 which has one end connected to the inner face of the door 8, while the opposite end is secured to the door frame in any suitable manner above said door 8.

It will be understood that a suitable roller 44 is mounted upon the outer wheel operated member 17, and is practically the same as the roll r 10 on the wheel operated member 1. It will also be readily seen that should the wheel of an automobile or other vehicle pass over the roller 14 or the roller 10 and swing the wheel operated member carrying said roller toward the door frame 7, the reciprocating operating rod 1 will be forced forwardly, thereby causing the operating chain 23 to pull the connecting chain 31 and swing the pivoted latch plate 3st to inoperative position against the tension of the spring 36 and also pull uponthe semicircular casting 31 to swing the door 8 upon its hinges to open position, the connecting rod 40 compelling the door 9 to also swing outwardly with the door 8 until both doors are in open position, as shown in Fig. 3. The spring 11 will immediately act to return the wheel operated members 4 to normal position. 7

As soon as a wheel of the vehicle passes over one of the vehicle operated members i and 17 in a reverse direction to swing said member in the opposite direction, the reciprocating rod'l will be drawn inwardly, causing the chain 2:2 to pull upon the chain 30 and again swing the latch plate 34 to inoperative position and then pull upon the opposite side of the semi-circular casting 24 to swing the doors 8 and 9 to closed position.

As soon as the wheel leaves the wheel operated members, the spring 11 will again act to return the wheel operated member 4. The spring 11 is only for the purpose of returning wheel member 4 to normal position. The outside wheel member 17 is returned to its normal position by the weight of the outer end of the operating bar and link acting as a weight on the roller 15 The operating bar 1 is only operated in conjunction with the doors 8 and 9. As will be noted, the links 3 and 14 are of special importance as to make a simple reverse of the mechanism. possible, (which is absolutely necessary) in that the wheel members 4: and 17 can return to a normal position without moving the operating bar, which would also operate the doors 8 and 9.

It is necessary that the wheel members 4 and 17 be able to assume a normal position without moving the operating bar 1. For instance, the front wheel of a car entering would .press the wheel member 17 downwardly and said wheel member 17 would assume a normal position as the wheel of the car leaves it. The rear wheel of the car would then pass over the wheel member 17, but this would not operate the mechanism, because of the link 14 which allows the wheel member 17 to be pressed downwardly any number of times in the same direction and returned to its normal position without operating the mechanism after the first time. This also holds good in the reverse movement of a car over said wheel member 17.

It will also be understood that when the wheel operated members 1 and 17 are returnedto normal position, the strain upon the latch operating chain 29 is relieved and the spring 36 permitted to act to return the pivoted latch plate 3% to normal position, so that it may again engage the keeper 37 to lock the doors 8 and 9 against movement when the doors 8 and 9 are in closed position. When the doors 8 and 9 are in open position, however, and the strain upon the latch operating chain 29 is relieved by a return of the wheel operated members 4 and 17 to normal position the spring 36 serves to return the pivoted "latch plate 84 to its lowermost or normal position and permit the same to engage the outer keeper 45 secured to the floor 6 outwardly of the doors 8 and 9 and'the frame 7.

\Vhile the preferred embodiments of the invention have been shown and described, it will be understood that minor changes in the details of construction, and arrangement of parts may be resorted to within the scope of the appended claims without departing from the spirit of the invention or sacrificing any of the advantages of the same.

What is claimed is:
