FASTENING MEANS FOR DGORS AND THE LIKE.

Application filed June 15, 1914.

To all 'whomit may concern Be it known that l, .FIUIIDEIU'GH W. Bnrnnn, a citizen of the United States, residing at New Athens, in the county of St. Clair and State of Illinois, have invented certain neu and useful Improvements in Fastening Means for Doors'und the like: and I do declare the following to be a full. clear, and exact description oi enable others skilled in the art to ivhich it a 'ipertains to make and use the same. U

My invention relates to improvements in means for fastening doors or the likc in any one of a number of adjusted positions.

In constructing my device, I employ a segmental rack for attachment to the door frame, a spring retracted latch for attachment to the door and, adapted to cooperate with said rack, a lever adapted to be pivoted to the door, and an elastic connection between the latch and the lever forprojecting the former into engagement with said rack.

To the above end, the primary obgect 0i the invention isto provide a device of the shown a portion of a character described provided with a flexible connection between the latch and the operating means therefor, thereby allowing the latter to be operated, to project the former, Whether said latch be located opposite a notch of the rack or opposite one of the teeth thereof. I

A secondary object of the invention is to proportion the parts in such a manner as to cause said elastic connection to retain the operatinp" lever in contact with a stop to move east dead center to project the latch.

With these and other objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is a perspective view of a por tion of a door and its frame showing the application of my invention thereto, the latch being projected; and Fig. :2 is a front elevation of the latch with the front of the casing removed.

in the accompanying drawings, 1 have door D which is hin 'ci'lly connected as at H to a door frame F. These parts may be constructed in any suitable manner and form no part of the present invention.

Serial No. 845 308.

attaching foot 1, secured to the upper cross bar of the frame F, is a segmental rack 2, the intermeiliate portion of said rack being provided with a pair of inwardly converging attaching arms 8 and 3, the arm 3 being provided. with an attaching i'o-zrt 4- Whichis likewise secured to a suitable portion of the frame. It may here be stated that the positioning of the rack 2 such as to cause the some to lie concentric with the hinges H. Pivctally secured to the. upper edge of the door I) is a latch :3. the same being here shown in substantially the. form of a bell crank lever which is pivotally supported within a suitable casing 6, a coil spring 7, attached to said latch and having its opposite end fixed, being employed for the pur pose of normally retracting the active arm 8 of said latch, said arm lying beneath the rack 2 and in position to be forced into any one of the notches 9 formed in the lower edge thereof. Spaced toward the free edge of the door, from the free end of the latch 5, is a guide roller 10, while directly beneath the roller lO'and disposed adjacent the knob K of the door, is an operating lever 11 WhlCl1.lS pivoted to said door at 12 and provided with a suitable operating knob or handle 13 at its free end. Attached .to the knob 13 or to any suitable part of the lever 11, is a flexible operating element 14, here shown in the form of a flexible wire, said element passing over the guide pulley l0 and being connected to the free end 15 of the latch 5, by a coil spring 16.

By this construction and arrangement of parts,-it will be seen that should the door he opened to such arrextent as to position the arm 8 of the latch 5 intermediate two of the notches 9, the lever 11 could be open A ated to equal advantage as if said arm 8 were directly beneath one of said notches, this being" due to the fact that the yielding connection 16 is provided, this connection allowing said operatin lever 11 to swing around its pivot 12 and into contact with the stop 17, said stop being positioned as to allow said lever to move dead center in which position it is retained by the tension of the spring 16. When now the door is moved in either direct-ion, the tension of said spring, being greater than the tension of the spring 7, will roclr the latch around its pivot will project the arm 8 into one 9, there by securely retaining the door in adjusted position, but it will be seen that movement of the lerer 11 in the opposite direction, will relieve all tension from the spring 16 and will allow the spring 7 to again retract the latch. 5.

I have described my invention as employed in connection with a door and door frame. it will be evident that it could be used to equal advantage with any sup port having an opening and a hinged opening therefor.

Having thus described my invention what I claim as new and desire to secure by Lettors Patent isz- 1. The combination with a support having an opening, and a closure for said opening hinged to said support, of a segmental rack secured to the support adjacent one end of the closure, a normally retracted latch carried by the closure, means for projecting said latch into engagement with the rack, and an elastic connection between said means and said latch.

2. The combination with a support having an opening, and a closure for said opening hinged to said support, of a segmental aliases raclr. secured to the support adjacent one end of the closure, a normally retracted latch carried by the closure, a lever pivoted to the closure and an elastic connection between said lever and said latch for projecting the latter into engagement with the rack.

3. The combination with a support hav ing an opening, and a closure for said opening hinged to said support, of: a segmental rack secured to the support adjacent one end or" the closure, a normally retracted latch carried by the closure, a lever pivoted to the closure, an elastic connection between said lever to the latch, and a stop for limiting the movement of said lever when swung past dead center to project said latch into en agement with the rack.

ln testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
