BOLT FOR DESKS AND OTHER STRUCTURES.

Patented Feb. 4, 1908.

,lpfiliciitioii filed December 19.1905. Serial No. 348.544.

T 0 all whom it may concern:

Be it known that I, CininLns E. JonNsoN, a citizen of the United States, and a resident of New Britain, in the county ol' Hartford and State of Connecticut, have invented a new and Improved Bolt for Desks and other Structures, of which the following is a specilication.

My invention relates more especially to that class of locks for securing a slidingl cover,

and the objectof niy invention is to provide an extremely simple and cheap construction of lock of this class; and a further object of the invention is to provide such a lock enibodying a minimum number of parts;

and a further object of the invention is to provide such a lock with self actuating means for throwing the bolt; and a further object ol'l the invention is to provide iiieans for acconiniodating a bolt to dilferent sizes of structures,

and also for simplifying the adjustnient oll A torni ol device in the use of which these objects niay be attained is illusthe parts.

trated in the accompanying drawings in Which- Figure I is a view in longitudinal section through the lower end ol a desk top showing the cover in rear elevation and the table in full, the cover being partly raised. is a like view showing the cover closed.

3 is a view in longitudinal section through the cover in a plane passing through the locking bolt and at right-angles to the plane of Fig. 4 is a detail view View of Figs. l and 2.

proved lock applied thereto.

Fig. 5 is an end view of the edge rail showing niy ini-i rail e of the sliding cover. This edge rail c,

in structures of this class, is formed of considerable width and does not project into the guide-ways c.

This edge rail may be of a thickness, as shown herein, to cover that port of the groove c opposite which the edge rail may be located, and guides are thus required to retain the edge rail in proper position with respect to its cooperating parts.

These parts, with the exception ol thel projecting guides lroni the rail niay be ol any ordinary and well-known construction and further and detailed description is therefore deemed unnecessary herein. 'lhe edge rail c has in its back surface a groove 6 terminating at each end in recesses 7. A lock case S is secured to the inner surface of the rail e and contains mechanism of ordinary and wellknown construction coninion to devices ol this class and operated as by means of a. key. The lock niechanisni includes bolt actuators 9 projecting froni the case, which actuators are reciprocated by lock niechanisni constructed in a nianner well-known to those skilled in the art.

.Bolt casiiigs 1() are secured in the openings extendiiig froni the recesses 7 through the rail c lo the end thereof. These casings extend beyond the ends of the rail c forming guides 11, that, hy engagement in the guideways c, direct the rail c in its sliding moven nient, maintaining it in proper position. These guides are so forined that a shoulder 11L is located between the guide and that portion of the casing located within the rail c, this shoulder forniing a stop for the casing to properly locate it within the rail. Locking bolts 12 are located within the casiiigs 1l), these bolts having shanks 13 extending through the casings and terminating in eyes 14 located in the recesses 7, said guides or dowels 11 thus lorining a shield or protector for the bolt in its sliding movement. Springs 15, each thrusting with one end against the inner wall of the casing and with the other end against a shoulder formed by the enlarged ends constituting the end of the bolt are employed to project the end of the bolt beyond the casing. The bolts 12 are connected with the bolt actuators 9 by flexible connections 1.6, in the structure herein shown these connections being composed of wire secured as by loops engaging a hook 17 on the actuators Q and hooked into the eyes 14 of the bolts, thus securing the parts in engagement.

Keepers 1S are properly located in the guide-ways e to receive the locking bolts 12, and it will be noted that the bolts 12 will be projected into the keepers each time the bolts are moved into :registering position therewith, as the springs 15 thrusting against the bolts will draw, through the intermediate connections, the keepers 9 from the position in which they may have been located by means of the key.r

It will be noted from this construction that the lock as a whole is adapted for use in any size of desk, it being required to supply with the other parts of the lock enough wire for the larger sizes of desks, and the proper adjustments caused by reason of shrinkage, Wear or the like may be readily made by letting out or taking up the flexible connection extending between the actuators and the bolts.

What I claim as my invention and desire to secure by Letters Patent is 1. A sliding cover, a cooperating member having a guideway and a keeper, a portion of said cover terminating without said guideway, a case borne by and projecting beyond the end of said portion and forming a guide to engage said guideway, a bolt located Within said casing and adapted to engage said keeper, and means Jfor operating the bolt.

2. A sliding cover, cooperating members located on opposite ends thereof, each. of said members having a guideway and a keeper, a portion of said cover terminating Without said guideway, casings borne by and projecting beyond said portions of the cover and forming guides for each end thereof engaging said guideways, a bolt located within said casing and adapted to engage a keeper, and means for operating the bolts.

3. A sliding cover including an edge rail having an opening extending inward from the end thereof, a cooperating member having a guideway and a keeper, a casing insertible Within said opening from but projecting beyond the end of the cover `to Jform a guide, a bolt located Within the casing and adapted to engage said keeper, and means for operating the bolt.

4. A closure including a side part having a guideway and a keeper, a cover having a portion projecting within said guideway and an edge rail ilexibly secured to the cover and terminating short of the guideway, a bolt casing having its end projecting beyond the end of the edge rail and engaging said guideway, a bolt located within said casing to engage said keeper, and means for operating the bolt.

5. A sliding cover having a casing recess extending inward from its end, a cooperating member having a guideway and a keeper, a casing located within said recess and having an enlarged end projecting beyond the edge of the cover to form a guide, said enlarged end having a shoulder abutting against the end of the cover, a bolt located within the casing and having its end projecting thereout of to engage said keeper, and means for operating the bolt.

6. A movable member and a cooperating member, one of said members having a guide- Way and a keeper, a case borne by one of said members andprojecting to form a guide engaging said guideway, a bolt located within said case and adapted to engage said keeper, and means for operating the bolt.

7. A movable member and a cooperating stationary member having a guideway and a keeper, a case borne by and projecting beyond the edge or' the movable member located without said guideway, said case forming a guide to engage said guideway, a bolt located within said case and adapted to engage said keeper, and means for operating the bolt.
