LAMINATED PADLOCK.
Application filed December The invention relates to padlocks of the type shown in my former Patent No. 1,490,987, April 22, 1924-. The said patent discloses a lock casing comprising a plurality oi laminated plates, riveted together to constitute a unitary structure, the laminations being provided with variously formed perforations permitting the rotation of a key O1 a design ap 'rO1:)riate to the several perforations of the laminations. In that construction, one of the laminations was provided with a projection which was adapted to engage a recess in the shank of the swiveled shackle of the lock, and so retain the shackle in position and prevent its withdrawal after the assembly of the laminations had. been completed. In assembling the elements shown in the said patent, it required considerable time and pains to etlect the engagement of the locking member with the shank of the shackle, and my present invention is directed to an improvement thereon, whereby the work of assembling the elements is greatly facilitated.
I achieve this result by providing one of the laminations with a floating locking member, one end of which is adapted to be brought into engagement with the locking notch in the shank of the shackle, and when such engagement of the floating member with the shackle is effected, I fasten the floating locking member against disturbance of its position, and so secure the shackle against withdrawal from the lock.
The invention will now be described in detail, and the novelty thereof pointed out' inthe appended claims.
In the accompanying drawing: 7 Figure 1 illustrates a vertical central section through the lock, showing the general arraiigement of parts disclosed in my former patent.
Fig. 2 is a sectional view 011 the line 22, Fig. 1.
Fig. 3 is a view similar to Fig. 1, showing the lock in the position in which it is held to permit the insertion of the shackle.
Fig. 4 is a view of the nail or pin which serves to retain the floating locking member in its position of engagement with the shackle.
In the drawing, the numeral indicates a laminated lock casing, and the numeral 11, the shackle thereof. The lock casing is :ituted ct a plurality OLE plates provided 7, 1927. Serial No. 238,371).
with variously lormed perforations, which when the plates are superposed and riveted together form a passage for the key 12.
The shank of the shackle 11 is provided near its lower end with a circumferential groove 13, opening out at one side into a flat surface 14, extending axially of the shank of the shackle for a distance equal to the thickness of three orfour oi the laminations.
One of the laminations oi the lock cas ing, indicated 15 in the drawing, is provided with an elongated opening 16, as shown in Fig. 2. A floating locking member 17 is placed in the opening 16, and confined therein by the laminations next above and below the particular lamination 15. The floating locking member 17 has a thickness slightly less than that of the lamination 15, and has capacity for free longitudinal movement in the recess thus formed. The severallaminations are assembled and secured together by means of rivets 18 to complete the lock casing.
The key 12 now inserted and given a quarter-turn to separate the branches of the shackle retaining spring 19, to permit the insertion of the shank of the shackle in the opening provided therefor, and the casing is turned to the positionshown in Fig. 3. Upon doing this, the sliding locking plate 17 will fall to the bottom of the recess in which it is housed, so as to enable the shank of the shackle to be inserted in position in the lock, the free end of the shackle at such time entering the recess 20 provided therefor. The lock casing is then reversed or given a half-turn, standing in its vertical plane. In suchposition, the sliding looking member 17 will fall to the opposite end of the slot, the end of the sliding locking member 17 being brought into engagement with the flat surface 14:, on the shank of the shackle 11. The expansion spring 21 seated in a bore in the shank of the shackle and confined by the bottom plate of the lock, will expel the shackle, when pressure on the latter is released, until the circumferential groove 13 is in line with the locking plate 17, the annular head 22 on the end of the shank of the shackle preventing further outward movement 01 the shackle. The point of the shackle at this time is disengaged from. thereeess 20, so that the shackle may be tn: '1. to one male The recess is reduced by a continuing central bore 23, which extends'beyond the lamination 15. A locking pin or nail 24 is now driven into and wedged tightly in the bore 23, behind the other end of the sliding locking plate 17, and serves to hold the locking plate in the position indicated in Fig. 1. The length of the sliding locking plate 17 should be approximately that of the distance between the pin or nail 24 and the flat surface 14 on the shank of the shackle.
The construction shown constitutes a very simple and efficient means for securing the shackle in the casing of the lock.
Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:
1. In a padlock, a plurality of laminated plates attached together to constitute a casing, a shackle the shank of which is mounted in an opening in the casing, a concealed member within the casing adapted to be moved to engage the shackle and secured in position to prevent removal of the shackle from the casing.
2. In a padlock, a plurality of laminated plates attached together to constitute a casing, a shackle the shank of which is mounted in an opening in the casing, the said shackle being cut away for an intermediate part of its length, a concealed member within the casing adapted to be moved to engage the cut away part of the shackle and secured in position to prevent removal of the shackle from the casing.
3. In a padlock, a plurality of laminated plates attached together to constitute a casing, a shackle the shank of which is mounted in an opening in the casing, the said shackle beingcut away for an intermediate part of its length, a concealed member adapted to be moved within the casing to engage the cut away part of the shackle and secured in position to prevent the removal of the shackle from the casing, and means for securing the concealed member against disengagement from the shackle. I
4. In a padlock, a casing compr sing a plurality ofi laminated plates secured together, one of such plates being provided with an elongated opening therein, a member adapted to be moved in the said opening, a shackle the shank of which is mounted in an opening in the casing, and means for fixing the position of the said member in engagement with the shank of the shackle to prevent removal of the latter from the casing.
5. In a padlock, a casing comprising a plurality of laminated plates secured together, one of such plates being provided with an elongated opening therein, a member adapted to be moved in the said opening, a shackle the shank of which is mounted in an opening in the casing, and means contained within the casing for fixing the position of the said member in engagemet with the shank of the shackle to prevent removal of the latter from the casing.
6. In a padlock, a casing comprising a plurality of lamimitcd plates secured together, one of such plates being provided with an opening, a member adapted to be moved in the said opening and confined therein by the adjoining plates, at shackle the shank of which is mounted in an opening in the casing, the said shank having a cut away portion intermediate its length, one end of the said member being engaged with the said cut away portion to prevent removal of the shackle from the casing, and a pin engaging the said member to secure the latter in engagement with the shank of the shackle.
7. In a padlock, a plurality of laminated plates secured together to form a casing, a shackle the shank of which is mounted in an opening in the casing, a concealed plate within the casing adapted to be moved to engage the shank of the shackle and prevent removal from the casing, the casing being provided with a recess for receiving the free end of the shackle and a continuing bore leading therefrom, and a pin driven into the said bore to maintain the engagement of the concealed plate with the shackle.
In testimony whereof, I have si ned my name at Milwaukee, this 3d day 0" December, 1927.
