Specification of Letters Patent.
Patented May 4, 1909.
Application filed June 10, 1908. Serial No. 437,759.
To all whom it may concern:
Be it known that I, HENRY R. TowNE, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Padlocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in padlocks and the method of making same, and it consists in the parts and combination of parts, and in the method of constructing and securing the parts together, as will be more fully explained and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in side elevation of my improved lock case. Fig. 2 is an end view of same. Fig. 3 is a view in side elevation of the body of the case. Fig. 4 is a view in elevation of same. Fig. 5 is a view in section on the line :cx of Fig. 3. Figs. 6 and 7 are views of the inner ring. Fig. 8 is a view of the blank from which the outer ring is formed. Fig. 9 is a view of one of the face lates showing one ear cupped and the other in its form before cupping. Fig. 10 is a view in edge elevation of same, and Figs. 11 and 12 are views of modified form of lock case.
The body of the lock is composed of an inner ring 1 provided with holes 2 and 3, and an outer ring 4 secured to the inner ring by rivets 5. The blank from which the outer ring is formed, is provided adjacent its ends with the slots 6 one of which registers with the slot 2 in the inner ring 1 and the other with slot 3 in said ring This outer ring 4 is made of any suitable ductile metal, and is .wider than the inner ring 1 as shown in dotted lines in Fig. 4, so that when the two rings are assembled, the inner ring will be central within the outer ring, with the latter projecting at both sides.
The outer ring 4 is cut away adjacent to its ends to form the rounded ears 7 and 8 bent outwardly at right angles to the ring, and erforated to receive the pivot pin of the shac 1e 9, while the ears 8 form housing or guides between which the free end of shackle enters the lock casing.
The face plates 10 of the lock case are preferably concavo-convex and circular except for the projecting cars 11 and 12 which latter conform in position to the ears 7 and 8 on the ring 4, and cover and conceal the same when the parts are assembled as shown in Figs. 1 and 2. The ears on the face plates 10, are, when formed, of the shape shown at 11, after which the outer edges are turned as shown at 12 forming flanges which overlap the outer ring and house the ears 7 and 8, and conceal the pin on which the shackle 9 is mounted.
The face plates 10, are of a size and shape to enter the outer ring 4, and rest on the seats formed therein by the edges of the inner ring 1, the ears 11 and 12 entering the slots formed by cutting out the ears 7 and 8.
One face plate 10 is thus assembled and permanently secured in place by spinning or otherwise turning the overhanging edge of outer ring 4 over the edge of said face plate. The lock mechanism is inserted and secured in place after which the other face plate is inserted and permanently fastened in place by spinning or otherwise turning the overlapping edge of ring 4 down onto the face plate. After the parts have been thus assembled and secured it will be impossible to get at the lock mechanism or the pivot pin supporting the shackle without destroying the lock.
The key opening for the lo ck may be through one face plate or through the'rings in the usual manner.
In the construction shown in Figs. 11 and 12, the inner ring 1 and outer ring 4 are made seamless, the inner ring forming the shoulders against which the edges of the face plate 10 rest. In this modification the ears on the outer ring, and the ears on the'face plates of the construction disclosed in Figs.
1 to 10 inclusive are omitted. In other respects the constructions are the same and the face plates are secured in place by spinning or otherwise turning the overlapping edge of the outer ring down out of the face plate.
The rings constituting the body of the lock may be formed by any of the familiar methods, as for example, from a flat annulus, punched from sheet metal and then converted by a cupping process into the desired form, or by punching a strip from sheet metal bending it into the form of a ring and securing its ends together.
It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described Without departing from the spirit and scope of my invention hence I would have it understood that I do not wish to confine r vself to the exact construction and arrangement of parts shown and described, but,
Having fully described inv invention whet I claim new and desire to secure by Letters Patent is 1. A loci: case comprisii ductile metal an inner ring the outer rin 1nd face pls edges on the inner ring nd tened in place by the overlspp the outer ring.
t l la (Me coniprisii I 4'. n rec an outer rinx" ductile metal, an of less width t the outer rin the suit rings having o peni for the ends of the shackle, and face pl seated at their edfles on the inner rinceiul permanently fastened in place by the overapping edges of the outer ring. 3 A look ease coinprisn V ductile inetel haviv outwardl ears, an inner ri' of less vidth than the outer rins" and ecured to the latter, and face 'UOSitlOil to plates having ears confornni 1 1n the ears on. the ring, me said face seated at their 0 es on the inner aer nanently fastened in place by leoping edges of the out r ductile iill j.
A lock case coinpris U an outer rin of ductile metal hev two pairs of outwa projecting; ears, one pair forming; beari' the shackle pivot and the other pair a guide or housing for the free end of the shackle, inner ring of less width than the outer rill; and face plates having flanged ears conforming to the ears on the outer ring, the said face '1 up; and
pro ecting being permanently secured against the of the inner ring by the overlapping of the outer ring.
5. A. look case comprising an inner ring an outer ring wider than the inner ring and riveted thereto, the outer ring provided with a pair of perforated ears bent outwardly, and face plates having flanged ears adapted to receive and cover the ears on the outer ring, the said fr ce plates resting; on the edges of the inner rin and hold in place by the turned edges of the outer ring.
6. A look case comprising a ring of ductile metal having outwerdly projecting ears, and internal annular its, and face plates having ears conforming in position to the ears on the rise the said face plates being; seated. at their and permanently edges on the annular sea-ts estened in place by the overlapping edges of the ring.
'7. lock case comprising a ring: of ductile nietel having two pairs of outwardly projecting; ears, one pair forming bearings for the l shackle pivot and the other pair a guide or housing for the free end of the shackle, the said ring being also provided with two in- 1 -isl annular seats, and face plates having flanged ears conforming to the ears on the outer ring, the said plates being permanently secured against the seats within the outer ring by the overlapping edges of said ring.
in testimonywhereof, I have signed this specification in the presence of two subscribing witnesses.
