'1 Claim. (01. 292-167) them from swinging open when they are closed.

Another object is to provide a device adapted for inside use for holding doors of offices and homes.

I am aware of the fact that door-holding devices have been used which are placed in operative position by pressure of the foot. As distinguished from such devices, another object of my invention is to provide a device which when released will-automatically move into operative position for holding the door.

The full objects and advantages of my, invention will appear in connection with the detailed description thereof, and the novel features of my inventive idea will be particularly pointed outin the claim.

;,In the accompanying drawings, which illustrate some of the forms in which my invention may be embodied, 1

Fig. 1 is an elevational view showing my device applied to a pair of garage doors. Fig. 2 is a View in section on the line 22 of Fig. 1, on an enlarged scale. Fig 3 is an elevational view of a door held I in open position. Fig. 4 is a fragmentary view showing a slight modification. Fig 5 is a view in section on the line 5-5 of Fig. 4 on an enlarged scale. Fig. 6 is an elevational view of a modified construction. Fig. '7 is a view in section on the line 7-7 of Fig. 6 Fig. 8 is a fragmentary View of a still further modification. Fig. 9' is a side view of a slight modification of the form shown in Figs. 4 and 5. Fig. 9 is a vertical sectional view of another form. Fig. 10 is a partial face view of this form. Fig. 11 is a vertical sectional view of a still further form. Fig. 12 is a partial face view of this last form. I Referring to the construction illustrated in th drawings, and-first more particularly to the form shown in Figs. 1, 2 and 3, a pair of garage doors 10 and 10 are shown in closed position in Fig. 1. One of my devices is shown applied to each of these doors. In constructing this form of the device I provide a rod 12 which at one end is bent atright The rod means of two staples 16 through which the rod is adapted'to slide. The staples are driven into the door in proper position toward the bottom thereof.

A nail 18 or similar device is driven into the door in proper position to form a rest or stop adapted to be engaged by the handle 14 to hold the rod 12 suffici ntly elevated so as not to engage the floor or ground. .A. second nail 20 or similar device which constitutes an anchoring element is driven into the door in such position that a coiled spring NT oFFicET 22 when attached at one end to this nail and attached at the other end to the handle 14 will be stretched so as to be placed under tension. Fig. 3 shows the door 10 in open position, the handle 14 having been turned to release it from the rest or stop 18. The tension of thespring' 22 causes the rod 12 to move'downwardly so that its lower end will engage the floor or ground and thereby firmly hold the door in the desired position.

Figs. 4 and 5 show a slightly modified form of the device applied to'a door 24 for use in an oflice or a home. In this case the staples 16, are re placed by bearings126- secured .to the door by screws 28 so that therod 12 may slide through the bearings. This form of the device is otherwise similar to that already described except that v a rubber tip 80.is placed on the lower end of the rod 12 for engaging with the floor.

Figs. 6 and 7'show another formof the device which is. particularly adapted for application to new'doors, such as door 32. In this" form of the device a vertical opening 34 is made in the door extending from the bottom thereof upwardly for a proper distance. of this opening a small panel is out out of one side of the door so as to leave a cutaway area 36 through which the rod 12 is inserted downwardly through the opening 34. A guide 38 for the rod is then placed in the opening 3% and the lower. end of the rod is provided with a' rubber tip 30. A plate 40 is secured over the cut-out area'36 by screws or other fasteners 42. This plate has a bayonet slot 44, the upper portion of 'whicliis adapted to form arest for the angular member 14 carried by the upper end of the'rod 12. The lower inner surface of the plate 36 carries a projection 46 which constitutes an anchoring element for attachment of the lower end of the a in use. Fig 9' shows a form similar tothat of fie Adjacent theupper portion its Figs. 4' and 5, the difference being that a plate 25 is secured to the door and the ends of this plate are turned out at right angles to provide bearings 26' in which the rod 12 slides.

Figs. 9 and 10 show another form of the device in which acompression spring and a holding dog are used in connection with a door 50. In this form a vertical opening 52'is made in the door extending from the bottom thereof upwardly for the proper distance. The upper portion of this opening is made smaller than the lower portion to provide a shoulder against which a ring 54 rests. Adjacent the upper end of this opening, one side of the door is cut away to provide a circular opening 56, the margin of which is rabbetted to receive a circular plate 58 held in place by screws 60. A shaft member 62 extends through the plate 58, the outer end of this member 62 being provided with a handle 64. Within the opening 56 the shaft 62 carries a. disc 66 and a barrel 68. The periphery of the disc 66 is provided with a notch 70 in which the inner end of a dog 72 is adapted to engage. This dog is mounted on a pivot 74 held in the opening formed in the upper portion of the plate 58. The outer end of the dog on its upper surface is knurled, as indicated at 76 in Fig. 1G in order that the dog may be readily engaged by the operator. A wire cable '78 is adapted to wind on the drum 68, the upper end of this cable being secured to the drum while the lower end thereof is secured to the upper end of a rod 86 which passes slidably through the ring 54. The lower portion of the rod 80 is formed with an enlargement 82. A compression spring 84' surrounding the rod 80 is interposed between the enlargement 82 and the ring 54. The enlargement 82 is adapted to'sli'de in a bearing 86 secured at the lower end of the opening 52. The enlargement 82 at its lower end carries a rubber tip 88. In Fig. 9, the dog '72 is shown in released condition in full lines, so that the compression spring 84 acts to hold the rod 80' downwardly with the rubber tip 88 engaged with the floor. In order to place the device but" of operative position, the handle 64 is turned and the dog '72 is moved into engagement with the notch 70. When the outer end of the dog '72 is pushed downwardly the, spring 8% acts instantaneously to lower the rod 80.

In the form shown in Figs. 11 and 12', the door.

90 is provided with a vertical opening 92 which extends from the bottom thereof upwardly for the proper distance. Adjacent the upper portion of this opening a small panel is cut out of one side of the door so as to leave a cut-away area 94 which is covered by a plate 96 secured in place by screws 98. A shaft member 100 extends through plate 96, the outer end of this shaft being provided with a wing member 102 for turning the shaft. The inner end of the shaft 100 carries a crank 104. A projection 106 extends out laterally from the crank 104. This projection extends through an opening in the upper end of a connecting rod 108 whose lower end is attached by a 'pivotlIO to the upper end of a rod 112. The lower portion: of the rod 112 is formed with an enlargement 114 adapted to slide in a bearing 116 secured at the lower end of the opening 92. The enlargement 114 at its lower end carries a rubber tip 113. The lower inner surface of the plate 96 carries a' projection 120 which constitutesan anchoring element for attachment of the lower end of a spring 122 whose upper end is attached to the projection 106 whereby the spring is placed under tension. Fig. 12 shows the wing member 102 turned to bring the crank 104 upwardly so that the rod 112 is held out of operative position.

Upon giving the wing member 102 a slight turn the spring 122 wi ll force the rod 112 downwardly I for engagement with the floor.

I claim:

A door-holding device comprising a rod mounted for vertical sliding movement in an opening at the lower end of a door, said door on one of its sideshaving a cut-out area at the upper end of saidopening, a plate secured over said outout area, a shaft passing through said plate, a

handle member on the outer end of said shaft, a

said projection whereby the lower end of said rod iscaused to engage the floor whensaid crank'arm is turned from upper toward lower position.
