HUGH TODD, OF SEATTLE, WASHINGTON.

DOOR AND GATE HANGER.

Specification of Letters Patent.

Application filed March 5, 1909.

Patented Aug. 30, 1910. Serial No. 481,479.

To all whom it may concem:

Be it known that I, HUGH TODD, of the city of Seattle, in the county of King, in the State of lVashington, one of the United States of America, have invented certain new and useful Improvements in Door and Gate Hangers, of which the following is the specification.

My invention relates to improvements in door and gate hangers and the object of the invention is to devise a strong and durable and efficient hanger which will always insure of the door moving evenly and without any liability of jamming, in which the use of tracks and wheels are dispensed with and in which all the working parts will be hidden from view in the door casing and by which the door is always kept in proper alinement. To effect this object I have constructed my invention in a manner which I will presently describe in reference to the accompanving drawing in which.

Figure 1, is a general perspective view of my door and gate hanger therefor showing the casing of the door broken away and in section and the door in the open position. Fig. 2, is a view looking from the opposite side of the door. Fig. 3, is a similar view to Fig. 1 showing the door in the closed position. Fig. 4, is a vertical sectional view taken through the door and door casing showing the cross connecting sprocket chains of the operating mechanism removed to more fully show the location and arrangement of the sproc ct wheels operating the mechanism. Fig. 5, is an enlarged detail elevation of the foot plungers and co-acting parts. Fig. 6, is a plan view of the parts shown in Fig. 5.

In the drawings like letters of reference indicate corresponding parts in each figure.

A indicates a door, A the door frame and A the hollow door casing into which the door is moved when it is in its open position. The upper and lower inner corners of the door are provided respectively with spaced upwardly and outwardly projecting arms A and A between which are respectively journaled the

sprocket wheels

2 and 3. The

sprocket wheels

2 and 3 are connected by the cross sprocket chain B. On the spindle B of the sprocket 2 is fixedly mounted a depending arm B On the spindle G of the sprocket 3 is fixedly mounted an upwardly extending arm C (see Fig. 2).

D is a journal bracket secured to a suit- I able portion of the interior of the door casing and in which is rotatably mounted the spindle D carrying the sprocket wheels E and F and on which is fixedly mounted at one end the depending arm D The lower end of the arms B and D are pivotally connected by a pin B G is a bracket secured on a suitable beam Gr located beneath the flooring G and in which is rotatably mounted the spindle G carrying the sprocket wheel H and on which is fixedly mounted at one end the arm G The upper end of the arm Gr and arm 0 are pivotally connected together. H is a crossed sprocket chain connecting the sprocket wheel H with the sprocket wheel E.

I is a supplemental bracket in which is rotatably mounted the spindle I carrying the sprocket .K and on which is fixedly mounted the arm P.

J is a bracket secured to the top of the door intermediate of the width thereof and in which is rotatably mounted the pin J and on which is fixedly mounted the arm J The upper ends of the arms J 2 and I are pivotally connected together by a pin I K is a crossed sprocket chain connecting the sprocket wheel K and F.

L are rollers mounted on suitable pins secured to the door, so as to engage with a suitable guide-way formed at each side of the door casing to the inside thereof.

L are rollers journaled in the flooring within the door casing to each end of the door and designed to form in conjunction with the roller L a guide for the door as it is being opened or closed.

M and M are a pair of grooved pulleys mounted on the spindle G and on which are reversely wound the cord M and M The cord M passes from the pulley M down around the supplemental bearing pulley M and from thence upwardly over the pulley M The cord M passes from the pulley M around the supplemental pulley M and thence ver a pulley M N and N are a pair of levers journaled at one end thereof on a bearing pin N mounted in a bracket hl and provided with foot plungers O and O pivotally connected at their opposite end by rods 0 and Such bracket N is supported on a suitable beam forming part of the flooring. To the levers N and N are connected the free ends of the cords M and M It will be noticed upon referring to Fig. 1

that each of the cross sprocket chains are provided intermediately of the length t-here of with connecting rods and turn buckles so that such chains may be readily adjusted to take up any slack therein.

Having described the principal parts involved in my invention I will briefly describe the operation of the same.

By pressing upon the foot plunger 0 with the foot the lever N is depressed so as to pull on the cord M and rotate the pulley M. By this means the arm G is thrown into the direction indicated by arrow carrying the arm C with it which as it moves forwardly is brought toward a perpendicular position thereby rotating the sprocket wheel 3 and carrying the door toward the closed position. By means of the cross connecting chain B the sprocket wheel 2 is similarly rotated so as to move the arm 13 and draw on the arm D to carry the upper end of the door toward the closed position. Simultaneously the sprocket wheel I-I being connected to the sprocket wheel E and the sprocket wheel F being mounted on the shaft D the sprocket wheel K rotates by means of the cross sprocket chain K so as to move the arms I and J 2 in unison with the aforesaid arms. By this means the door is carried into the closed position shown in Fig. 3. When it is desired to open the door the foot plunger O is depressed so as to operate the lever N, cord M and pulley M, so as torotate wheel H and move the arm Gr in the opposite direction thereby giving a reverse motion to the mechanism to open the door.

From this description it will be seen that I have devised a very simple form of door hanger in which all pulleys and guides for directly supporting the door are dispensed with and in which all the working parts are hidden from view in the door casing and which may be readily kept in alinement by adjusting the cross connecting sprocket chains by means of the turn buckles as before described.

What I claim as my invention is:

1. In a gate or door hanger, the combination with the door, of an arm mounted in a suitable bracket above the door and an arm mounted in a bracket extending from the rearmost upper corner of the door, said arm being pivotally connected at its lower end to said first mentioned arm, a supplemental arm mounted in a bracket secured to the top of the door in proximity to the front thereof, and a co-acting arm mounted in a bracket above the door, the free ends of the supplemental and co-acting arms being pivotally connected together, and means operatively connected to said arms to swing the same to carry the door horizontally in a forward direction, as and for the purpose specified.

2. In a gate or door hanger, the combination with the door, of an arm mounted'in a bracket located above the door, an arnr located beneath the door, an arm mounted in a bracket located in proximity to the lowermost rear corner of the door and pivotally connected to the aforesaid arm mounted beneath the door, a supplemental arm mounted in a bracket secured to the top of the door in proximity to the front thereof, a co-acting arm mounted above the door, the free ends of the supplemental and co-acting arms being pivotally connected together and means operatively connected to said arm for swinging the same so as to impart a horizontal backward or forward movement to the door, as and for the purpose specified.
