COMBINED LATCH AND LOCK.

SPECIFICATION forming part of Letters Patent No. 625,217, dated May 16, 1899. Application filed September 26, 1898. Serial No. 691,912. (No model.) I

To all whom it may concern:

Be it known that I, FRED W. TOBEY, a citizen of the United States, residing at Grand Rapids, in the'county of Kent and State of Michigan; have inveu ted new and useful Improvements in a Combined Latch and Look, of which the following is a specification.

This invention relates to certainnew and useful improvements in a combined latch and, lock; and the invention consists in the combination of parts and details of construction hereinafter described.

The objects of my invention are, first, to form a combined latch and lock for refrigerators and analogous purposes in which the inner face-plate may be attached without the means of screws or bolts; second, in the improved means for moving the locking-doginto a different position either to lock the latch or to unlock it, and,third, in the various combina tions of partshereinafter 1n ore fully described, and pointed out in the claims. These objects I accomplishby means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the combined lock and latch constructed in accordance with my invention, showing the latch lowered in position to engage with a suitable catch. Fig. 2 shows a rear elevation of the same, illustrating the covering-plate secured in position without screws or bolts. shows an edge elevation, illustrating the position of the face-plate and latch. Fig. 4 shows a rear elevation with the face-plate removed,exhibiting the springs,locking device, and latch. Fig. 5 shows a sectional view on line X X of Fig. 2.

Similar letters refer to similar parts throughout the several views.

The lock is provided with a shell or case, preferably of metal, (shown byA.) A thumblever turning upon the bolt, shown by B, is provided with a projection J, adapted to engage with the latch C. The latch 0 turns upon a stud or bolt made integral with the case or shell and is provided with a spring, which spring has itsstationary end secured by means of two studs or pins, as shown in Fig. 4, having a free end bearing against the Fig. 3-

and in dotted lines it is shown in position to .lock the latch in the catch, said dog being provided with a shoulder P, which engages with the latch when said dog is thrown into the position shown by dotted lines in said figure. A spring II has its stationary end held by two studs made integral with the case,

as shown in said Fig. 4. The free end of the said spring H is bent at an angle, so as to furnish two flat bearings, which rest against the flat surfaces of the flange E of the dog. In the position shown in the dotted lines the outer or farther surface of the spring H has a bearing against the inner surface of the flange E, thereby holding said dog out of locking position. Vhen the dog is thrown into the position shown by the dotted lines in Fig. 4, the spring H bears against the outer surface of the flange E, said flangeE bearing against the second surface of the spring H, said spring thereby holding the dogin looking position until the sameshall have been thrown out by means of the key.

The shell or case A is provided with two projections at its front edge, (shown by K and L-,) said projections, with the case, forming ways, into which is slid or crowded the face-plate R. M is also a projection from the shell, under which projection is passed the face-plate R and held securely in position. In order to retain the face-plate R securely in position, I provide an opening in the faceplate R, which opening is shown by O. This opening in the face-plate is crowded into position, passes under the projection M, and the projection M may bend downwardly into said opening, thereby securing said face-plate to the shell. By this construction I entirely obviate the necessity of screws or pins in fastening the face-plate to the shell. It will. be understood that the shell is made of some material which is somewhat flexible, so that the projection M may readily bend downward slightly, soas to engage with the hole in the face-plate R, making a very secure attachment for the face-plate.

The dog D is provided with two projections between which the key passes. The key being turned in one direction throws the dog out of locking position and being turned in the opposite direction throws it-into locking position. The dogturns upon a bolt placed at some distance from the keyhole, so as to give a slow motion to the dog. The latch has a portion cut away from beneath, which al- .lows the extended end of the dog to rest beneath the latch, the latch serving the purpose of holding the dog in position and forming a way for the travel of what 1 term the locking end of the dog. The notch P of the dog, however, does not pass beneath the latch, but is of sulficient length to bear upon the upper surface of the latch when the dog is thrown into locking position and to be entirelyout of the wayof the latch when thrown out of locking position. When the dog. is thrown out of locking position, the flange comes in contact with the edge of the case, thereby limiting the throw of the dog in that direction. When thrown into locking position, the end of the dog which passes beneath the latch meets a shoulder on the latch, which limits the throw of the dog in that direction. This is shown by the dotted lines in Fig. 4. The thumb-lever B is placed near the edge of the case, as shown in Fig. 1, being in a convenient position for use and in position to secure the greatest leverage upon the latch.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is

1. In a combined latch and lock, a case provided at two opposite points with projections to retain the face-plate, and having a flexible projection at a third point adapted to be bent into an opening in the face-plate to retain the latter in place, substantially as described.

2. The combination with a lock-case which is provided with opposite projections, of a faceplate adapted to slide between said projections, and a flexible projection forming part of the case and adapted to be bent into an opening near the edge of the face-plate to prevent the latter from being withdrawn, substantially as described.

3. The combination with a case having two opposite projections, of a face-plate adapted to lie between and be retained by said' projections, a third flexible projection forming part of the case, to be bent into an opening near the edge of the face-plate, a latch turning on a fixed pivot and having a free end projecting from the case, a spring to bear on said latch, a dog turning on a pivot between its ends and having a projection to pass beneath the latch and a shoulder to engage the latter when the dog is in locking position, and

a spring having two angular portions at dif- FRED V. TOBEY.
