SAMUEL IEELLEGRINO, OF MONESSEN, PENNSYLVANIA.

PADLOCK.

To all whom it may concern:

Be it known that I, SAMUEL PELLEGRINO,

residing at Monessen in the county of VVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Padlocks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to pad locks and has for its object to provide a lock of such class, in a manner as hereinafter set forth, with a spring pressed locking member engaging in the shackle for maintaining the latter closed and to further provide a lock with means to permit of sufliciently shifting said spring pressed locking member to release the shackle when the occasion so requires.

With the foregoing and other objects 111 view the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views :Figure 1 is a longitudinal sectional view of a pad lock in accordance with this invention. Fig. 2 is an end view. Fig. 3 is aside elevation. Figs. 4 to 9 are details.

Referring to the drawings in detail 1 denotes a cylindrical lock casing having its inner face formed with a pair of lengthwise extending grooves 2 which are arranged opposite each other. The casing 1 is closed at one end through the medium of a head 3, the latter having abutting thereagainst a retaining member 4, provided with a centrally disposed opening 5 having a stepped wall which provides a shoulder 6 and which forms the opening 5 of two different diameters. The retaining member 4 has a lateral lug 7 which engages in the opening 8 formed in the casing 1 for the purpose of maintaining said member 4 in position against said member 3. The member 4 is notched as at 9, and said notch 9 registers with an opening 10 formed in the body of the casing 1 at one end thereof. The head 3 is notched as at 11, and the inner wall of said notch 11 Specification of Letters Patent.

is beveled, and the said beveled inner wall flush with the beveled inner wall 12 of the a citizen of the United States of Amerlca,

notch 9. The casing 1, opposite the end provided with the opening 10, has an opening 13.

Arranged longitudinally of the casing 1, is a rotatable spindle 14, having a head 15, which is arranged in that portion of the opening 5 of greater diameter and is prevented fromlongitudinal shifting by the shoulder 6. The spindle 14 intermediate its ends has peripheral threads 16, and said spindle 14 is of a length to project from that end of the casing 1 provided with an opening 13. The retaining member 4 constitutes a bearing for one end of the spindle 14.

The reference character 1? denotes a disk and the said disk 17 has a pair of lugs 18 which are seated in the edge of that end of the casing 1 which is provided with the opening 13. The lugs 18 prevent shifting of the disk 17 The reference character 19 denotes a shackle, and the arms of the latter are indicated at 20, 21. The free terminus of the arm 20 is reduced as at 22, extends down through the opening 10, and into the notch 9, and is pivotally connected to the member 4 by a pin 23. The beveled wall of the notch 11 and the beveled wall 12 of the notch 9 provides a clearance for the reduced terminus 22 of the arm 20 when the latter is swung in one direction on its pivot. The free terminus of the arm 21 is reduced as at 24 and it extends down through the opening13. The reduced terminus 24 has a groove 25.

Arranged within the casing 1, is a longitudinally extending shiftable sliding support 26, the latter has an enlarged opening 27 for the passage of the spindle 14 and said member 26 is formed on one face with a pair of lugs 28, having mounted there be tween a nut 29. The latter permanently engages with the threads 16 of the spindle l4 and is prevented from rotation by the lugs 28. The lugs 28 are formed on one face of the member 26, and the latter has proi jecting from its other face an arm30.

Rotatably mounted upon the spindle 14 is a locking member 31, formed with an anelongated nular flange 32, the latter being notched as at 33 to provide clearances. The flange 32 is adapted to engage in the groove 25 of the arm 21 of the shackle 19 for the purpose of locking the same. WVhen the member 31 is shifted into the notch 33 the arm 21 of the shackle 19 can be swung from out the cas ing 1.

Formed integral with the locking member 31 and projecting forwardly therefrom is a sleeve 33, which provides a bearing for the outer end of the spindle 1 1 and said sleeve 33 finds a bearing in the disk 17. Formed integral with the outer end of the sleeve 33 and arranged exteriorly of the easing 1 is a disk 36 which is employed for retainingthe locking member 31. The spindle 14L projects forwardly from the disk 36 and has fixed thereto a disk 37 for the purpose of turning said spindle. The locking member 31 has a seat 38 for the free end of the arm 30.

Surrounding the spindle 1 1 and interposed between the member 1 and the nut 29, to prevent looseness of the latter, is a coil spring 39 and surrounding the spindle 14 and interposed between the disk 36 and the locking member 31 is a coil spring 40. The function of the spring 10 is to maintain the locking member 31 in the groove 25 of the arm 21 of the shackle.

It will be assumed that the parts are in theposition shown in Fig. 1. The spindle 14: is rotated in one direction so that, the nut 29 will move toward the member, 1 thereby releasing the tension of the spring 40. The disk 36 is then revolved which carries a locking member 31 therewith until the notch 33 is opposite the groove 25, which will provide a clearance for the inner terminus ofthe arm 21 of the shackle and said arm can be swung clear of the casing 1.

The locking member 31 is prevented from rotation by the arm 30 which engages in the seat 38. hen the support 26 is shifted toward the member by the expansion of the spring 4-0, the arm 30 is' moved out of the notch 38 in the member 31.
