and adjustable holding means for holding the door in an open position.

It is, therefore, an object of the present in vention to provide a door holding device which is particularly suited for use with slide connections for doors.

It is another object to provide a door holder which may be readily adjusted to alter the position in which the door may be held open.

It is a further object to provide a door .holder which may be easily rendered operative or inoperative, and which is provided with a stop for limiting the opening movement of a door when the holder is in inoperative position.

It is another object to provide a door holder which operates with a minimum amount of vibration and noise.

It is a further object to provide a door holder which may be easily assembled on a slide bar without the aid of tools.

It is another object to provide a door holder which cooperates with a stop, both of which may be regulated by a single adjustment.

These and other objects not specifically enumerated are contemplated for this invention, as will be apparent to one skilled in the art as the following description proceeds.

In the drawings- Figure 1 is a perspective view of a holding device constructed and installed onv a door in accordance with the present invention.

Figure 2 is a side elevational view of a slide connection with the holding means in holding position.

Figure 3 is a fragmentary View in cross section of a slide connection and holding means.

Figure 4 is a fragmentary view in cross section showing the holding means in inoperative position.

Figure 5 is a cross sectional view taken on the line 55 of Figure 3.

Figure 6 is an end elevation of a device embodying this invention.

Referring to the drawings, a bracket or frame 9 is positioned within a cut-out portion I I! in the upper edge of a door II. The frame may be formed from a single strip of metal having an upright portion 12 and a base portion 13. End

members I4 and I5 may be formed by bending upwardly the ends of the base [3. The base has openings to receive screws l6 which secure the frame to the cut-out portion of the door.

A slide bar I! has journals I8 and I9 which are supported by suitable journal bearings provided by the ends [4 and I5. The slide bar may be of any cross section and is substantially square in the present embodiment. Thejbar-may be maintained in supported engagement with the frame in any suitable manner, such as by a slip 20 engaging the end |5of the frame and a shoulderon the bar. An inwardly extending finger Y 2| may be provided by the upright portion l2 for engaging the vbar and limiting its, rotation with respect to the frame. 7 V v The bar I! has a threaded portion 24 adjacent one end on which is screwed a stopor spring seat 22 which is provided with an internalannular groove 23. A coil spring 25'is slidably mounted on the bar adjacent the spring seat 22.

A crosshead or slide 26 is slidably mounted on the bar I! and is provided with bearing surfaces which conform to the cross sectional shape of the bar. The slideis provided with a spindle 21 on which an operating arm 28 is pivotally mounted, and a pin 29holds the arm onthe spindle.

The undersurface of the slide bar is provided with a channel or groove 33 which is of sufficient width to accommodate a curved resilient holding member 3|. The holding member 3| has a downwardly turned portion 32, the end of which engages the annular groove 23 of the seat 22. The coil spring 25, through which the member 3| extends, may support the member in such a manner that the free end 33 of the member is maintained inengagement with a cam rod 3'3.v

- The cam rod 34 extends substantially the length of the groove 30. One end of the rod extends through a hollow portion of bar I! and through end member I4, terminating in a turned-down portion or crank 35. The rod is provided with a notch in its narrow surface for engaging a bearing pin 38 which extends across the groove 30' adjacent the end. The rod 34 hasa width greater than its thickness. so that when it is turned up on edge by movement of the crank 35, the notched edge of the rod engages the pin and the narrow edge of the rod cams the end 33 of holder 3| downwardly. When the crank is turned the other way, as illustrated in Figure 6; the broader side of the rod engages the pin and the end 33 of the holder is permitted to move upwardly under the influence of coiled spring 25 which has previously sible from the top'of the door.

been distorted by the downward thrust of holder 3|. It will be noted that it is not essential that the coil spring return the holder in the manner described since the slide Will move it up as it passes over the holder.

In operation, as the door II is opened, the bar I! moves with it and the arm 28, which is secured at one end to the door frame, causes the slide 26 tomove toward the holding member 3|. When cam rod 34 is in the position shown in Figure 2, with its wider surface in a vertical position, it holds the central portion of the resilient holder 31 below the margins of groove 30. As the slide reaches the holder it passes over the end 33 until the lower surface of the slidewedges against the undersurface of holder 3|. .The holder being resilient, the slide is frictionally engaged and held with a minimum of noise and vibration. A slight pressure on the door will release the slide and permit the door to be returned to a closed position.

Torender the holderinoperative, thecrank .35 is moved so thatthe wide surface of the cam .rod 34. is in ahorizontal position, thereby permitting theholder tobe moved upwardly in the groove 30 as theslidepasses over it. The slide 26.may now pass over the holdern3l until it en- .gages and compresses .coil spring-25 against the springseat 22.

The position of the holder as -well as the coil spring :and spring seat maybe-altered as a unit by merely screwingthespring seat 22 in the desired direction. This maybe easily accomplished after the-device has been installed in a door by rotating the spring seat, which is readily acces- The downwardly turned end 32 of the holder freely rides in the annular groove 23 of the spring seat as it is revolved.

It will be noted that when the holder is in inoperative position it is. notnecessary that-all of member- 3| be maintained within the groove30, since slide Edwin-force theprotruding portion up in the grooveas it passes over that portion of the slide-bar, provided the holder does not extend downiar enough to bind the slide -andfrictionally hold it, as when it is in operative position.

The curved shape of holder 3| and itsresiliency permit the slide to become gradually engaged and disengaged as it'approaches and recedes from a holdingposition, WlththB resultant smooth and quiet operation of the device.

It will be further noted that simplicity of construction of this device enables it to be completely assembled and installed without tools,

after the frame has been secured to the door.

It is to be understood that the invention is not limited to the exact embodiment of the device shown, which is merely by way of illustration,
