l SPECIFICATION forming part of Letters Patent N o. 588,561, dated August 24, 1897.
Appiioiiion inea. January 1s, 1896. serial No. 575,350. (No man.)
To all whom t may concern.: Be it known that 1, ALFRED FAIRHU'EST, citizen of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented a new and useful Lock, of which the following is a specification.
This invention relates to locks for doors, boxes, drawers, and for general use where it is required to secure parts by projecting a boltacross the joint formed between the said parts when closed.
For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.
The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacriicingan'y of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a front elevation of a lock constructed in accordance with this invention. Fig. 2 is a rear elevation thereof having the obverse side of the case removed and showing the relative disposition of the parts when the bolt is projected. Fig. 3 is a View similar to Fig. 2, showing the position of the parts when the bolt is withdrawn. Fig. 4 is a detail viewof the front or main portion ofthe case, the bolt and its operating mechanism being removed. Fig. 5 is va transverse section of the lock on the line X X of Fig. 1.
The same reference-numerals denote similar and corresponding parts in all the figures of the drawings.
The case is composed of two parts 1 and 2, which are secured together in anyconvenient manner. The part 1 is formed on its rear side with sideV ribs 3 and a rear rib 4 of equal depth and with a circular recess 5, and a keyhole 6 is centrally disposed with respect to the recess 5 and is surrounded by a circular depression 7 to receive a portion of the web of a key 8 used for projecting and withdrawing the bolt 9. A circular disk 10 is snugly fitted within the circular recess 5 and comes iiush with the inner or rear side ofthe part 1 of the case, and this disk has a keyhole 11 to register with the keyhole 6, so as toreceive the end of the key stem and web, whereby the said disk 10 can be turned so as to operate the bolt 9.
The bolt 9 is rectangular in shape and isy guided in its movements between the side ribs 3 and has an elliptical opening 12 near its rear or inner end to receive a circular boss 13, eccentrically formed on the rear side of the circular diskv 10 and by means of which the bolt is projected or withdrawn upon rotating the said circular disk 10, as will be readily understood. The elliptical-shaped opening 12 is formed with its major part to one side of the center of the bolt 9, and its inner end engages with and limits themovements of the circular boss 13 when turning the circular disk 10 to project or withdraw the bolt 9, as most clearly shown in Figs. 2 and 3. If theopening 12 projected to an equal distance from a central line, no provision would be had for limiting the movements ofthe circular disk and the latter could be turned indefinitely in one or the other direction and it could not be known with certainty when the bolt was fully projected or withdrawn, but by disposing the opening to one side of the central line the movement of the disk is limited both when the bolt is projected to its full extent or entirely withdrawn.
It will be seen that the lock is devoid of springs and other parts which are likely to derangement, and is therefore simple and effective for the purpose designed.
The lock is extremely simple and compact and operates in conjunction with a key, the web or bit of which has a portion entering and working in the circular `depression and in the keyhole formed inv the disk and boss, the depression providing clearance `for the bit, whereby the key is steadied and prevented from withdrawal until the keyholes 6 and 11 are brought into register.
Having thus described the invention,what is claimed as new is- A lock constructed substantially as specified, the saine comprising a case inclosed on three sides and having a centrally-disposed keyhole, and formed on its inner side with a circular depression and a circular recess concentric with each other and with the keyhole, the circular recess being of less depth' than IOO ister with the keyhole of the case, and having a circular boss ecccutrically disposed on its rear side to operatelin the elliptical opening of the bolt; the keyhole extending into the boss and adapted to receive the other portion of the web or bit of the key, substantially in the manner set forth for the purpose specified.
ln'testimony that I claim the foregoing as in y own I have hereto affixed my signature in the presence of two witnesses.
