This invention relates to a fastener for cold storage and refrigerator doors, the general object of the invention being to provide a spring actuated bolt and keeper member which are so constructed and arranged that the door will be held closed at all times and the bolt can be moved to releasing position by a handle from outside of the door and the door can be pushed open from inside the refrigerator with means for locking the bolt in looking position.

This invention-also consists in certain other features of construction and in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention indetail, reference will he had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of part of a refrigerator, with the invention thereon, and

, showing the bolt locked in projected position.

Figure 2 is a horizontal sectional view through Figure 1, with the locking device in lan.

Figure 8 is a section on line 3-3 of Figure 1.

Figure 4 is asimilar view, but with the bolt retracted by the handle.

Figure 5 is a similar view, but showing the parts in the position they occupy when the door is pushed open from inside the refrigerator.

Figure 6 is a view looking toward the inner end of the device.

Figure 7 is a section on line 77 of Figure 1.

Figure 8 is a section on line 88 of Figure 4.

Figure 9 is a section on line 9 9 of Figure 1.

' Figure 10 is a View showing the hub and cam parts of the handle. I

of the door frame. A plate 1 is fastened to the door and is provided with the guide 2 at its forward or outer end and the block 3 at its inner end. This block is formed with the spaced bearing parts 4 and the forwardly extending tubular part5 which is exteriorly threaded. A bearing member 6 is also carried by the plate at the inner end of the guide. A bolt, composed of the shaft 7 and the L- shaped plate 8 fastened to the front or outer end of the shaft, has its shaft rotatably and slidably arranged in the bearing members and the long arm of its L-shaped plate sliding in the guide. A collar 9 is fastened to the shaft and a nut 10 is threaded on the tuto hold the bolt in projected position with a roller 12 on the outer or forward end of the long arm of the plate 8 engaging a bell crank keeper 13 which is pivoted to a bracket 14 fastened to the door frame B. A spring 15, carried by the bracket, engages the keeper.

As shown in Figures 3, 4 and 5, the keeper and its bracket are so arranged that the spring 11 will hold the bolt with its roller 12 in engagement with the keeper and with the keeper in a position to hold the door closed, but when pressure is exerted against the inside of the door, the roller will exert pressure on the short arm of the keeper,.thus rocking the keeper on its pivot and causing the keeper to press the bolt rearwardly so that the door will be opened.

In order to lock the door in closed position, I pivot a locking plate 16 to one end of the block 3 so that the plate can be swung between the bearing parts 4 into engagement with the reduced rear end 17 of the shaft so that the edge of said plate will engage the shoulder formed by the reduced end and thus prevent rearward movement of the bolt. This plate is slotted to receive a staple 18 on the block 3 and a padlock or the like is adapted to be passed through the staple to lock the plate 16 in looking position.

A handle 19 is formed with a hub 20 through which the shaft passes and one end of this hub is ournaled in the bearing memher 6 which is formed with a tubular cam part 21 for engaging one edge of the cam part 22 formed at the center of the hub.

. The other end of the hub extends into a cam member 23 which is keyed to the shaft, as

7 shown at 2 1, so that said cam member is slidably but non-rotatably connected with the shaft and this .cam member abuts the collar 9 when the bolt is in projected position. This cam member has its camedge engaging the other cam edge of the cam part 22. As shown, all the cam edges are'of double constructionto give an even and smooth action to the bolt when the handle is actuated. The

cam members 21 and 23 each has slots 25 the nut, a tensioning spring between the nut and collar, means on the guide having the sleeve for locking the bolt against movement when shifted to locking position, cams for moving the bolt when released from the last named means, and a handle for operating the cams.

- 8. In a door fastener, a spring pressed bolt, guides for the bolt, a sleeve on one guide and receiving the bolt, a nut adjustable on the sleeve, a collar fixed to the bolt spaced from the nut, a tensioning spring between the nut and collar, means on the guide having the sleeve for locking the bolt against movement when shifted to locking position, cams for moving the bolt when released from the last named means, and a handle for operatingthe cams, said cams being disposed opposite each other and on opposite sides of the handle.

In testimony. whereof I aflix my signature.

raised position with the cam parts in neutral position.

g s Thus it will be seen that when the handle is'swung downwardly, the cam part 22, engagaing the cam members 21 and 23, will force the member 23 rearwardly so that said member will exert force against the collar 9 and thus push the bolt rearwardly or into retracted position, against "the action of the spring 11, and as shown in Figure 4, Then the door can be opened. When thespring 27 returns the handle to raised position, the cam member 23 will move forwardly, thus releasing pressure on the collar, so that the spring 11 will project the bolt. I

As will be'seen, the cam parts will not interfere with the retraction of the bolt when they are in neutral position so that the door can be pushed open from the inside, as before explained. I

It is thought from the foregoing descrip tion that the advantages and novel features of the invention will be readily apparent.

' It is to be understood that changes may be made in the construction and in the combination' and arrangement of the several parts, provided that such changes fall withinthe scopeoffthe appended claims.

l Vhat I claim is 1. Ina door fastener, a spring pressed bolt, guides for the bolt, a sleeve on one guide and-receiving the bolt, a nut adjustable on the sleeve, a collar fixed to the bolt spaced from the nut, a tensioning spring between the nut and collar, and means on the guide having a sleeve for locking the bolt against movement when shifted to locking position.
