SPECIFICATION forming part of Letters :Patent No. 554,615, dated February 11, 1896. Application filed Octobell', 1895. Serial No. 565,978. (No model.)

T0 all whom, t may concern:

Be it known that I, NICHOLAS H. CoLwELL, a citizen of the United States, residing at Kenton, in the county of I-Iardin and State of Ohio, have invented certain new and useful Improvements in Door-Fasteners, of which the following is a specication, reference being had therein to the accompanying drawings.

My invention relates in general to an improved doorastener designed for use on the doors of refrigerators and other like structures, and specically to that class of fasteners for refrigerator-doors in which on raising the handle the door is both unfastened and pried slightly outward, the latter action being desirable from the fact that the door frequently swells and binds in the casing.

The invention, broadly stated, consists in a door-fastener having a pivoted drop-handle, a prying-finger whose longitudinal axis is at a right angle to the pivot of the handle, a latchnose projecting laterally at a right angle from one end of the prying-finger, and a keeper against which the prying-finger bears on the upward movement of the handle, pressing the door slightly upward and outward, and with which the latch-nose engages from below on the downward movement of the handle.

The invention also consists in certain details of construction and combination of parts which will first be described in connection with the accompanying drawings, and then pointed out in the claims.

Figure 1 of the drawings is a perspective view of a combined latch and lock embodying my invention. Fig. 2 is a rear elevation of the same with the back-plate and keeper removed. Fig. 3 is a side elevation of the lock with the keeper in section7 showing the positions of the handle, latch-nose, and prying-iinger when the parts are in normal position, the prying-finger and the shoulder with which the finger contacts in operation being shown in dotted lines. Fig. 4 is a view similar to Fig. 3, but showing the parts in the positions they occupy when the handle is being raised to disengage the' latch-nose from the keeper. Fig. 5 is a broken sectional view of the combined latch and lock on the line x x,

Fig. 2, showing the locking-dog in the locking position. Fig. 6 is a perspective view of a portion of the handle and its integral parts, comprising the prying-linger, the latch-nose, the handle-pivot, and the lug on the pivot adapted to engage with the locking-dog and also to limit the upward movement of the handle. Fig. 7 is a perspective View of the keeper. Fig. 8 is a perspective view of a latch embodying my invention. Fig. 9 is a side elevation of the latch with the keeper in section, showing the position of the handle, prying-finger, and latch-nose when the parts are in the normal position, a portion being shown in dotted lines. Fig. l0 is a view similar to Fig. 9, but showing the parts in the positions they occupy when the handle is being raised to disengage the latch-nose from the keeper. Fig. l1 is a plan view of the latch with the keeper removed, showing the parts in normal position. Fig. 12 is a side elevation of the keeper.

Referring to the drawings on Sheet 1, A represents a lock-casing having a removable back plate a, and B a keeper.

O represents a drop-handle, provided with short pivots c c', adapted to work in recesses l, formed in the sides of the casing, the back plate abeing provided on its sides with forwardly-projecting lips 2, adapted to close recesses l and serving to hold the pivots therein; but, though two short pivots are shown, a continuous pivot-rod extending across the casing may be substituted if desired.

On one side of the handle, and preferably integral therewith, are formed a prying-finger D and a latch-nose E, the longitudinal axis of the prying-finger being at a right angle to the pivot of the handle, its end being adapted to bear in operation on a shoulder on the keeper, hereinafter described. The latchnose E, having a roundedfaee, projects laterally at a right angle from one end of the prying-finger, the longitudinal axis of the latchnose being parallel with the handle-pivot but in a plane below it.

On the inner side of the casing A is an ordinary locking-dog F, having the usual spring 3 to prevent accidental displacement, the dog being provided with a downwardly and forwardly extending projection 4, adapted on movement of the dog to override a lug 5, formed on the pivot c of the handle, which lug by contact with the back plate also serves to limit the upward movement of the handle. The locking-dog is designed to be operated by the usual key (i.

The retaining portion Z1 of the keeper B is rounded on its lower end, as at 7, and on the inner edge of the keeper is formed a shoulder b, for a purpose hereinafter stated.

The parts being assembled and in place on a refrigerator or other like structure the operation will be as follows: Assuming the drophandle to be locked in its normal position, when the latch will be in engagement with the keeper, then on unlocking the handle and raising it the latch-nose will be swung outward and thereby disengaged from the keeper, by which time the prying-finger will contact with the shoulder h on the keeper, which will result, on a slightly farther upward movement of the handle, in pressing the door upward and outward, when the lug 5 will have been turned so as to contact with the back plate of the lock, thereby limiting the farther upward movement of the handle. To close the door it is only necessary to push on it, when the latclnnose will come into contact with the rounded end of the retaining portion I) of the keeper, riding down it and thereby raising the handle until the latch-nose has passed in rear of said retaining portion, when the handle will drop by gravity.

Referring now to Figs. S, 9, 10, 11, and 12 on Sheet 2 of the drawings, it will be seen that in applying my invention to a latch, the principal modifications relate to the form of the handle and the manner of pivoting it. Instead of using a U-shaped handle, such as above described, I employ for the purpose of alateh a single-bar drop-handle C, and form the prying-finger D and the latchnose E on a short pivot-bolt 8, which passes through two lugs 0 formed on a plate A, adapted to be secured to the door, and on this pivot-bolt I secure the handle preferably by means of a set-screw lO. For the purpose of limiting the movement of the handle I recess it on both sides in rear of the pivot so as to leave shoulders ll, which are adapted to come into contact when the handle is raised to a horizontal position, with shoulders l2 formed on the inner sides of the lugs 9. The keeper I5 of this latch is substantially the same as the one previously described, having the rounded retaining portion b and shoulder b.

It will be noticed that in the operation of this latch, as well as in the operation of the combined latch and lock, the latch-nose enters the keeper from below.

Ilaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a door-fastener, ahandle pivoted in a suitable support, and a prying-finger and a latch-nose adapted to be operated by the ha-ndle, -the longitudinal axis of the prying-finger being at a right angle to the handle-pivot and the latclnnose projecting laterally at a right angle to one end of said iinger, in combination with a keeper against which the iinger presses on the upward movement of the handle and wit-h which the latch-nose engages from below on the downward movement of the handle.

2. In a door-fastener, a handle, a pivot for the handle, a support in which the pivot is mounted, a prying-linger, a latch-nose projecting laterally at a right angle to one end of the finger, said prying-finger and nose being formed integral, and means for limiting the upward movement of the handle, in combination with a keeper against which the finger presses on the upward movement of the han- -dle and with which the nose engages from below on the downward movement of the handle.

3, Ina combined latch and lock, a lock-case, a U-shaped drop-handle pivoted inthe sides thereof, a pryingnger and a latch-nose formed integral with one branch of said han dle, and a lug carried by the handlepvot and adapted to contact with the case to limit the upward movement of the handle, in combina tion with a keeper with which said iinger and nose coact in the manner and for the purposes set forth.

4. In a combined latch and lock, a lockcase, a U -shaped drop-handle pivoted in the sides thereof, a prying-finger and' a latch-nose formed integral with one branch of said handle, a locking-dog, and a lug carried by the handlepivot, said lu g being adapted when the handle is in the normalposition to be engaged by the locking-dog and to contact with the case when the handle is in the horizontal position, in combination with a keeper with which said finger and nose coact in the manner and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NICHOLAS II. COLXVELL.
