' noon HOLDER.

Application filed May 6,

This invention relates to a door holder and has for its principal object a door retainingrod held in offset position relative to the door on which it is to operate.

A further object is to provide a holder as above referred to working in combination with a means for retaining the door in a pre-determined position.

With the foregoing and other objects in view, as will appear as the description proceeds, the invention consists of the novel construction. combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application, in which:

Fig. 1 is a perspective sectional view of a door showing the preferred embodiment of my invention in position thereon.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a corresponding view to Fig. 2 with the door hinged at right angle position to that shown in Fig. 2.

Fig. 4 is one preferred embodiment of the guide member used in combination with my invention.

Fig. 5 is a modified form of the guide member.

Like numerals of reference designate corresponding parts throughout the different views.

6 indicates a door and 7 the side portions of a door frame. The door is hingedly connected at one side to the frame 7 by means of the hinges 8. The door 6 is considerably thinner than the door frame 7 and is sup ported from the outer edge of the movable portion of the hinge 8. Preferably across the central panel of the door 6, I connect a holder rod. 9. The holder rod 9is hingedly connected to the frame 7 in the half hinge 10 by a suitable pivotal bolt, the pivotal point being positioned on the face of the door frame 7 slightly out of pivotal alignment with the hinges 8. 11 indicates a guide member having an outwardly protruding portion 12, which portion has an elongated slot 14 therein. This guide member 11 is suitably secured by screws or otherwise to the central panel of the door 6. 15 is a guide member having a transverse opening in alignment with the slot 14. when this guide member is properly positioned on the central panel of the door 6 as shown in Fig. 1.

1927. Serial No. 189.426.

16 is a thumb set screw threadedly engaged in the. guide member 15, the purpose of which will" be hereinafter mentioned.

The holder rod 9 is reciprocally positioned through the slot let and the transverse open- 'ing in the guide member 15.

When the door is closed as shown in Fig. 2, it will be noted that the half hinge 10, the outer portion of the elongated opening 14 and the transverse opening in the member 15 are in alignment with each other. When the door is hinged to its right angle open position as shown in Fig. 3, the elongated slot 14 and the transverse opening in the guide member 15 are swung out of alignment with the half hinge 10, so as to cause the holder rod 9 to be sprung as at 17 when it is in contact with the protruding portion 12 of the guide member 11.

When the door is in position as shown in 2 or when it is turned to full open position, the holder rod 9 is at its least tensioned position, while when the door is in the position shown in Fig. 3 it is at its greatest tensioned position in the protruding portion 12 of the guide member 11 and if pushed in either direction, will swing to closed or full open position respectively.

While the door is opening and closing, the thumb set screw 16 is turned out to give free reciprocation to the holder rod 9 in the guide member 15. When it is desired to retain the door at any predetermined position, the door may be swung to that position and the thumb set screw tightened to retain the holder rod 9 against reciprocating motion through the guide member 15.

In a guide member such as shown in Fig. 4-, a certain amount of friction might be caused on account of the holder rod 9 being tensioned against the inner face of the protruding portion 12. In Fig. 5, I illustrate a guide member provided with a bearing pivot-ally mounted in the inner end of the slot 14 and the holder rod 9 during any reciprocation will contact against this bearing and will overcome to a great extent the friction above referred to.

The foregoing specification and annexed drawings disclose the preferred embodiment of my invention, but it is to be understood that minor changes may be resorted to in the commercial adaptation of my invention without departing from the scope of the invention as hereinbefore claimed.

What I claim as new is:

The combination with a hinged door, a holder rod of spring material hinged from a pivotal oint out of alignment with the 5 hinging polnt of said door; a retainer clamp seoured'to the inner face of said door and having an opening therein through which the free end of said rod extends; a tensioning member secured to the'inner face of said 10 door intermediate said pivotal point and said retainer clamp; said tensioning member having a transverse elongated slot therein through which said rod extends, said slot being of such length that said holder spring rod will be in normal alignment between said pivotal point and said retainer clamp when said door is in either closed or full open position and adapted to tension said rod out of alignment when said door is in hinged position intermediate said positions and said tensioning member being provided with a bearing contacting with said rod.

In testimony whereof, I affix my signature. JACOB M. STUDEB.
