Specification of Letters Patent.

Patented July 111, 1911.

Application filed August 22, 1910. Seria1 No. 578,321.

T 0 all whom it may concern:

Be it known that I, RAFFAELE FnoLA, a citizen of the United States, and a-resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Look, of which the following is a full, clear, and exact description.

This invention relates to locks, and has reference more particularly to a lock serving the purpose of a padlock, but having the casing so constructed that it fits closely around the staples or eyes which receive the padlock bolt, and fits closely against the door or other support carrying the staples, the lock comprising the casing, a movable bolt, a keeper for the bolt, and key-controllable pin-tumbler mechanism for operating the keeper.

An object of the invention is to provide a simple, inexpensive and durable lock, which serves the purposes of the ordinary padlock, which, when in position prevents the staples or eye-bolts from being filed or out, and which renders difiicult other unauthorized methods of opening the look.

A further object of the invention is to provide a lock of the class described, in which the lock bolt proper is operated by key-controllable mechanism of the pin tumbler type, which permits of a large number of variations in the key-controllable mechanism, and which may have the casing of different shapes adapted for use with different kinds of doors or other closures.

The invention consists in the construc tion and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a front elevation of an embodiment of my invention, showing the same Fig. 5 is a fragmentary longitudinal section of one end of the lock; Fig. 6 is a view similar to Fig. 5, showing certain of the parts in different positions; Fig. 7 is a plan view of a modified form of the lock, showing a special kind of hasp used with the same, and illustrating in cross section a part of a door to which the lock is applied; Fig. 8 is a side elevation of the modified form of the lock; Fig. 9 is a rear elevation of the modified form; Fig. 10 is a similar view of a further modified form of the lock; and Fig. 11 is a plan view of the last-mentioned modified form of the invention, showing in cross section part of a door with which it is used.

Before proceeding to a more detailed explanation of my invention, it should be clearly understood that the same constitutes an improvement upon the form of lock shown in my United States Patent No. 924,331, issued June 8, 1909. The lock can be fashioned from any suitable material and the casing can be ornamented in different ways. Preferably, the outside of the lock casing is rounded and entirely smooth, so that it affords very little grip for attack by means of a tool, in an attempt to force the look. It can be used with ordinary staples generally employed, which receives the bolt of a pad-lock, or it can be used with specially formed eye-bolts which permit the lock casing to fit snugly against the door, and which are just the proper size to receive the bolt. The bolt itself is telescopically extensible and has a part which, when the key is inserted and operated, is released, and is resiliently projected from the casing, to permit the lock to be opened by hand. The end of the bolt when it is in a locked position within the casing, is preferably flush with the outer surface of the same. Certain of the details of construction shown for example, in the accompanying drawings, form no part of the invention, and can be varied in accordance with individual preference and special conditions, without departing from the underlying spirit of the invention.

Referring more particularly to the drawings, Figs. 1 to 6 inclusive, I provide a lock casing 10, which is preferably in the form of a semi-ovoid, and which is hollow and has at each end an inwardly extending sleeve 11 which constitutes a bolt opening. The lock casing at the flat face is open to receive the staple and eye-bolts 12 carried by the doors 13. The lock bolts 14 are movably mounted in the sleeve 11, and each consists of an outer cylindrical member or sleeve 15 and an inner cylindrical member 16, having at the outer end a head 17, and movable within the outer member 15. At the end of the casing adjacent to the sleeves 11 are walls or partitions 18, each having a stud or projection 19, which engages in a slot 20 of the outer sleeve 15 of one of the bolts 14 which limit the movement thereof. Each of the inner sleeves has a slot-'21 in which engages a stud or projection 22 of the outer sleeve, to'limit the relative movement of the parts 15 and 1.6. The latter has in addition a slot or groove 23, which receives a stud or projection 24 of the outer sleeve 15. A helical or other spring 25 is located within each groove 23 and engages at one end of the latter, and also engages the corresponding stud 24, tending normally to project the inner member 16 of the bolt. The latter at the inner end has a transverse recess 26, for a purpose to appear hereinafter. The casing 10 has a substantially central opening 27 in which is located the key cylinder 28 of the pin-tumbler mechanism. The key cylinder is rotatably mounted in a suitable opening of the pin chamber 31, which has an extension 29 and is secured by means of a screw 30 or in any other suitable manner, within the casing. Above the key cylinder, the pin chamber has a plurality of recesses 32 in which are located the pin drivers 33, and the springs 34 which tend normally to project the same. The key cylinder has a plurality of openings 35 in which are movably mounted the pins 36, adapted to be engaged by a suitably formed key 37, the key cylinder having a longitudinal slot 38 for the reception of the key. The pin tumbler mechanism operates in the usual maner, and if a properly proportioned key is inserted in the cylinder it will so position the pins 36 that the junction of the pins and the drivers is located at the edge-of the key cylinder, so that the same can be rotated to operate the look. It carries at the inner end a dog 37, secured thereto by means of screws 38 or in any other suitable manner, and having at the ends, projections 39. lVithin the casing, at the opposite sides thereof, are extensions 40, upon which are pivotally mounted keepers 41, by means of pivot pins or screws 42. The'keepers have laterally dis posed ends 43, adapted to engage in the end recesses 26 of the bolts to hold the same in their retracted, locked positions. Each keeper, further, has a curved edge or cam 44 adapted to be engaged-by one of the dog projections 49. When the key cylinder is rotated it displaces the keepers from engagement with the bolts. U-shaped springs 45, or springs of any other suitable form, are mounted by means of pins 46, upon the extensions 40, and engage the keepers, tending to hold them in normal, locked positions. The ends 47 of the inner bolt members 16 are rounded so that when the bolts are forced inward they will engage the keeper extremities, to displace them until the parts 43 of the keepers can enter the bolt recesses 26. Vithin the casing, adjacent to the extensions46, arewalls or partitions 48 spaced 7 from the extensions 18, so that the staples or eye-bolts 12 can be received in the casing. The partitions 48 have openings 49 through which the lock bolts pass.

In Figs. 7, 8 and 9 I have shown a modified form of the lock, in which the casing 50 is of semi-ovoid form, and has at the flat side, and nearer one end than the other, a cutaway part of angular form, which re ceives within it an arm 52 of a hinged'hasp 53 secured to a door 54 or other closure, the lock casing at the same time receiving the staples or eye-bolts 55 which pass through openings in the hasp. The lock casing at one end,'has a bolt 56 similar in form to the bolt 14, and movable through an opening in a partition 57 within the lock casing. A pivoted keeper 58 is movably mounted by means of a pin 59 or in any other suitable manner, upon the partition 57, and is held in a normal position by a spring 60. The key-controllable pintumbler mechanism 61, similar to the corresponding mechanism in the previously described form of the lock, is located at one end of the casing,

and has a dog 62 adapted to engage the keeper 58, to displace the same when the mechanism is operated by means of a suitable key 62. A guard plate 64 is mounted upon the flat face of the lock, and is secured in position by means of screws 65 or in any other suitable manner.

In Figs. 10 and 11 I have shown a further modified form of the lock, in which the casing 66 is of substantially triangular cross section, so that it can fit snugly into the angle formed by a door 67 and the frame 68 thereof, or in any other similar locality, being formed to receive staples or eyebolts 69 carried respectively by the door and the frame, and at angles with each other. A bolt 70, similar to the bolts 14 and 56, is movably arranged within the casing, which has a partition 71. A keeper 72 is movably mounted by means of a screw pin 73, upon the partition, and is held in a normal, locked position by means of a spring 74. It is displaceable against the tension of the spring by a dog 7 5 associated with the key-control-' lable pin-tumblermechanism 76, similar to the corresponding elements shown in the other forms of the lock, and operable by the key 77 in the usual manner.

The dog 62 of the form of the lock shown in Figs. 7, 8 and 9 has an edge recess 6%, which cooperates with a stop 64* of the casing to limit the movement of the key-controllable mechanism. Similarly, in the form of the lock shown in Figs. 10 and 11, the dog 75 has an edge recess 75 which cooperates with a stop 66 of the casing, to limit the movement of the key-controllable mechanism.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:
