FASTENING DEVICE FOR ICE-CHESTS.

. Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed September 10, 1912. Serial No. 719,672;

To all whom it may concern:

7 Be it known that 1, ANDREW J. ALLISON, a citizen of the United States, residing at Hartshorne, in the county of Pittsburg and State of Oklahoma, have invented certain ures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in eccentric latches forvthe doors of refrigerators, coolingrooms, windows or other doors requiring force to close and release the same and where an airtight joint is desired.

The invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation showing a door held in a locked relation by means of my invention. Fig. 2 is a view showing the latch in the act of tilting the keeper to allow the latch point to pass behind and against the door strip, a further lifting of the latch handle causing the door to be locked, and Fig. 3 is a detail perspective view of the latch and strip adapted to be attached to the door, the latch being designed to tilt back to a vertical position after the latch has passed by said catch.

Reference now being had to the details of the drawings by letter, A-designates a door, a portion of which only is illustrated but which is adapted to be hinged in the usual manner, and C is a portion of a door casing. A cylindrical bearing member D is formed of a late which is bent upon itself, and has anges D which are fastened to the casing 1n such a position that the bearing portion will be horlzontally disposed. Said bearing portion is provided with an angular and inclined slot E.

A; locking bolt or latch is designated by letter F and is of cylindrical form and has latch;

in, said bearing member, said bolt or latch having an angled end F, the purpose of a rotary and longitudinal movement withwhich will be presently described. A handle H projects from said bolt orlatch through the angled slot E and serves as means for rocking the bolt and movin'gthe same longitudinally when the shank portion of the handle comes in, contact with the inclined edges of the slot. It will be:

noted on reference to the drawings that,

when the latch is in the-position shown in Fig. 1, it is in a locked relation and, when in theposition shown in the dotted lines in 1, will allow the door to be swung open. A plate K is fastened .to the door,'preferably near its free end, and to said plate s pivotally mounted upoh a pin N a keeper 0 which has a lug or" heel Q-projecting I laterally therefrom, aportion of which keeper is bent to form a lipor fiange R. An upper portion of the kee er has an elongated slot K formed therein, and a pin S fastened'to the door asses through said slot and serves as a guide to the keeper as it swings to its limit in opposite directions. It will be noted that the pivotal .point of said keeper is at one side of the center of the latter for the purpose of throwing the greater part of the weight to one side which will have a tendency to prevent the upper portion from falling back from over the The'operation of my invention is as follows r-VVhen the door isajar, the bolt or latch is adapted to assume the position shown in dotted lines in Fig. 1. After the door is closed, the handle is swung to the position shown in Fig. 2 of the drawings when the angled end F of the bolt will contact with the inclined flange R, causing the keeper 0 to tilt to the position-shown in dotted lines in Fig. 1 and allow said angled .end to pass behind thekeeper O and afur ther upward throw of the lever to the position shown in solid lines in Fig. 1 will cause the angled edge of the bolt to contactwith the projection Qand tilt the keeper 0 to an upright position, as shown in solid lines in Fig. 1 of the drawings, thus securely looking the door. A reverse downward movement of the handle will cause the angled end of said bolt to swing outwardly and contact with the inner face of the keeper 0 and im part the initial starting movement to the opening of the door, this being accomplished while the latch is rocking and before a longitudinal movement is imparted thereto. As the shank portion of the handle comes in contact with the inclined edges of the slot in the bearing D, an outer longitudinal movement will be imparted to the bolt for the purpose of throwing the angled end thereof out from behind the keeper 0 and which will allow the door to be swung open.

By the provision of a latch made in accordance with my invention, it will be noted that a simple and efficient means is accorded whereby the keeper may be operated manually' in the manner disclosed, the locking of'the door being'securely held in a locked relation when the handle is at its highest throw and the door released automatically when the handle is at the limit of its throw inits opposite direction.

A device made in accordance with my invention will afford means whereby a powerful leverage may be obtained and by which the door may be operated readily regardless of the swelling or warping of the door and the initial loosening of the door from a jammed position easily accomplished.

What I'claim to be new is 1. An eccentric latchfor doors, comprising a combination with a door and casing to which the same is hinged, abearing member fastened to the casing and having an angled slot in its wall, a rocking bolt mounted in said bearing and having an angledend .and-

a handle fixed to the bolt and extending through said slot, a keeper pivotally mount- I ed upon the door and having a beveled flange against which said angled end is adapted to contact to tilt the keeper, a projection upon said keeper against which said angled end of the bolt contacts to return weaves the keeper to its normal upright position, as set forth.

2. An eccentric latch for doors, comprismg a combination with a door and casing to which the same is hinged, a bearing member fastened to the casing and having an angled slot in its wall, a rockingbolt mounted in said bearing and having an angled'end and a handle fixed to the bolt and extending through said slot, a-keeper pivotally mounted upon the door and having a beveled flange on one edge thereof against which the end of the bolt is adapted to contact, causing the keeper to tilt, the upper portion of the latter having a slot therein, a pin pro- I jecting from the door and passing through said slot, and means for returning the keeper to its normal position, as set forth.

3. An eccentric latch for doors, comprising a combination with a door-and casing to which the same is hinged, a bearing member fastened to the casing and having anangled slot in its .wall, a rocking bolt mounted in said bearing and havingan angled end and a handle fixed to the bolt and extending through said slot, a bail-shaped keeper pivotally connected at its lower end to .the door and having a beveled flange on one edge thereof against which the end of the bolt is adapted to contact and cause the keeper to tilt, said keeper having a lateral projection and against which the angled, end of the bolt is adapted to contact to throw the keeper to its normal upright position, as set forth.

In testimony whereof I hereunto afix my signature in the presence of two witnesses. ANDREW J. ALLISON. Witnesses;
