Application May 3, 1946, Serial No. 667,058

1 Claim. 1

The invention relates to locks and more particularly to a type of lock which employs a rotatable lock cylinder functioning in conjunction with a sildable lock bolt.

The object of the invention is to provide a lock which is of extreme simplicity and therefor economical to manufacture and easily installed. A further object is to provide a look which is very rugged in construction and therefore practically burglarproof.

The lock is particularly designed to replace the well known hasp lock used on garage or store doors or for that matter on any door where it is desired to use a lock of great strength.

Other objects and advantages will become apparent as this speciiication proceeds. Referring to the drawings forming a part thereof and in which a preferred form of the invention is illustrated:

Fig. 1 is an elevational view showing the lock in position on a door. In this view the locking bolt in one of 'its locked positions;

Fig. 2 is a longitudinal sectional view on a larger scale and taken on line 2-2 of Fig. 4. In this View the locking bolt is in another one of its locked positions.

Fig. 3 is a longitudinal sectional view taken on line 3 3 of Fig. 2. In this view the looking bolt is locked in its open position; and

Fig. 4 is a cross-sectional view taken on line 4 4 of Fig. 2.

Referring again to the drawings the reference numeral I designates the door to which the lock I I is to be attached and I2 the door jamb to which the keeper I3 is secured. The usual door stop is indicated at I4. The lock may be secured to either side of the door depending upon which way the door opens and the door jamb I2 might be another door of a pair of double doors.

The lock I I comprises a body or block I5 having a longitudinal opening I6 formerly therein for the accommodation of the slidable locking bolt Il. Just above and intersecting the opening I6 is a transverse bore I to accommodate the lock cylinder member I9.

The slidable locking bolt I'l is tapered at one end 20 to facilitate its entrance into the keeper and from there on to a point 2l (see Fig. 2) is cylindrical. The opposite end 22 is rectangular in cross section to form a stop as hereinafter described and the lower half of the bolt between the squared end 22 and the point 2l is rectangular in cross-section as particularly indicated at 23 in Fig. 4. The opening I6 in the block I5 conforms to the shape of the bolt and thus any rotational movement of the bolt is prevented. The bolt is provided with another stop 24 toward itsv tapered end and the purpose of this stop will hereinafter become apparent. The upper rounded portion of the slidable locking bolt is provided with a plurality of semi-circumferential grooves or recesses, three being indicated at 25, 26 and 21.

The forward part of the lock cylinder I 9 is provided with a key hole slot 30 for the reception of a key 3| and the conventional spring pressed locking pins 32 cooperate with the serrations of a proper key so that the lock cylinder may be rotated to either lock or unlock the locking bolt as hereinafter described. The rear portion of the lock cylinder is provided with a semi-circumferential groove or recess 33. The inside surfaces of the grooves or recesses in the bolt correspond in shape to the exterior of the bolt; and the outer surface of the bolt corresponds to the inside surface of the recess 33 in the cylinder I9.

In order to prevent longitudinal movement of the lock cylinder a pin 35 is passed through its rear end, beyond the groove 33 and the projecting ends of the pin are accommodated in a counter-bored portion of the bore I8. Thus forward longitudinal movement of the lock cylinder is prevented. A plate 35 suitably secured in position over the pin closes the counter-bore and prevents rearward movement of the lock cylinder.

The lock is secured in place by virtue of a stud 40 formed integral with or suitably secured to the block I5. This stud passes through an opening in the door I0 and is firmly secured thereto by a nut 4I and washer 42.

The keeper I3 is secured to the door jamb by suitable screws one of which is indicated at 43 and is provided with a suitable opening 44 for the reception of the slidable locking bolt.

In Fig. l the lock cylinder I9 is in engagement with the groove 26 in the slidable locking bolt, the bolt has entered the keeper and the door is locked. Insertion of the key 3l into its slot 30 and rotation of the lock cylinder 180 will bring the groove 33 over the bolt I I and permit the bolt to be manually moved to either of its other two positions.

One may wish to enter the locking bolt further into the keeper, or the lock due to circumstances may be so positioned on the door that a maximum movement of the locking bolt is necessary to have it enter the keeper. The bolt is then manually pushed to the position of Fig. 2. At this time the squared end 22 of the locking bolt engages the block I5 and properly positions the bolt so that by rotation of the lock cylinder the 3 groove 33 will be moved out of engagement with the bolt and the solid part of the lock cylinder will enter the groove 2l in the locking bolt and the parts Will be locked in this position.

When it is desired toopen the lock and insure it staying open the locking bolt is manually moved toward the right in Figs. 1, 2 and 3 until the stop Z4 engages the side of the block as illustrated in Fig. 3. At this time the groove 25 is in line with the lock cylinder and the lock cylinder is rotated until its solid part enters the groove 25. The key is then removed and thus the possibility of inadvertently moving the locking bolt to one of its locked positions is eliminated.

Several changes in details of construction and arrangement of parts as would occur to one skilled in the art are to be considered as coming within the spirit of the invention as set forth in the appended claim. y

I claim:

A lock comprising a body, mounted in said body and having transverse recesses formed side by side in its outer surface, a keeper having an opening to receive said bolt, the body having a bore and a rotatable lock cylinder therein disposed crosswise of said bolt, and bear- 2 a bolt slidably ing a recess formed therein and extending length' Wise of said bolt, the last-named recess having its inside surface shaped to permit longitudinal movement of the bolt with respect t0 the body, and the recesses in the bolt being shaped to permit rotary movement of the cylinder therein, said bolt projecting at both ends from said body and having stops to limit its movement in either direction, a stud projecting from the body for mounting and securing the lock in place, and a stop pin wholly Within the lock to retain the cylinder in said bore.
