Patented Oct. 5, 1937 PATENT OFFICE LOCK CONSTRUCTION Henry F. Keil, Scarsdal e, N. Y., assignor to Franois Keil & Son, Inc., a corporation of New York Application February 20, 1934, Serial No. 712,125

14 Claims.

This invention relates to a lock construction and more particularly to padlocks or the like.

One of the objects of this invention is to provide a lock construction which will be simple, practical and thoroughly durable. Another object is to provide a construction of the above character which may be easily manufactured with a minimum amount of labor and with inexpensive materials. Another object is to provide a construction of the above character which while being durable and lasting is nevertheless neat in appearance. Another object is to provide a construction of the above character which may be easily assembled and repaired with extreme ease. Another object is to provide a construction of the above character which may be disassembled for purposes of repair without undue damage to any of the parts thereof. Another object is to provide a construction of the above character which is capable of permanently carrying a plurality of spare parts in a convenient manner without sacrificing economy of manufacture and effectiveness of operation. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the fea- 'tures of construction, combinations of elements and arrangements of parts as will be exemplified in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing in which is shown one of the various possible embodiments of this invention, I

Figure 1 is an exploded perspective view showing my lock construction as partially assembled;

Figure 2 is an enlarged vertical sectional View taken along the line'2--2 of Figure 1, and

Figure 3 is a vertical sectional view taken along the line 33 of Figure 2 of the casing of my lock construction, the other parts thereof having been removed for purposes of clarity.

Similar reference characters refer to similar parts throughout the several views of the drawmg.

As conducive to a clearer understanding of certain features of this invention, it might here be pointed out that considerable difficulty has been encountered in the repair of 'lock constructions and more particularly padlocks or the like. These locks are necessarily rugged in construction and hence often difiicult to disassemble for purposes of repair. When such locks are disassembled, often it is necessary to so damage the outer casing or various parts connected thereto that the lock is practically ruined and cannot be put back into its original condition. Further still, such locks are used in widely scattered sections of the country where it is difficult to ob-' tain spare parts upon short notice, thus causing delay for a considerable period of time while the spare parts are shipped over long distances. One of the objects of this invention is to provide a construction in which the several difficulties hereinabove mentioned are successfully and efficiently overcome.

Referring now to Figure 2, there is generally indicated at ID a casing comprising the main body portion of my lock. Formed within casing I is a cylindrical recess II to be more fully described hereinafter, while a chamber |2 extends transversely along the right-hand end of casing Ill, as viewed in Figure 2, a portion thereof being connected with recess A pair of holes l3 and M extend through the top of the casing (the right-hand side as viewed in Figure 2) into chamber i2 and a recess l5 of considerable length extends into casing Hi in'registry with hole I4.

The end portions l6 and ll of a U-shaped part or shackle generally indicated at |8 extend through holes l3 and I4. Thus as clearly shown in Figure 2, end l6 may rest at one end of chamber l2 and end I! which is of greater length extends into recess l5. One side of end portion I1 is reduced to form a slot l9 connected to an annular groove 20 substantially near the extremity of end portion H. A pin 2| fits within a hole 22 formed in casing ||I so that the extremity thereof extends within slot I9. The upper end of pin 2! is preferably enlarged to hold it in this position but, as will be explained more fully hereinafter, pin 2| may drop out of the hole when recess II is empty.

Thus under certain circumstances to be described more fully hereinafter, U-shaped part l8 may be moved in a right-hand direction as viewed in Figure 2 until the end of pin 2| engages shoulder |1a of end portion I! immediately adjacent groove 20. Due to the length of slot l9, end portion 6 is then free from casing l0 and accordingly part |8 may pivot about end portion I! as an axis, pin 2| being in groove 20. Further outward movement of part I8 is prevented by pin 2|, but when the part is rotated so that slot I9 is in registry with pin 2|, end portion I6 is in registry with hole l3 and the part may be moved to the left to assume the position shown in Figure 2.

Fitted within recess is a lock cylinder or key plug generally indicated at 23 preferably having an annular flange 24 formed on one end thereof and seated within a recess 25 in the left-hand end of easing I0, as viewed in Figure 2. Thus flange 24 rests against shoulders forming the bottom of recess 25 and is held in this position by a pin 23 (Figure 2) extending through a portion of casing If] and having an end fitting within a circumferentially extending groove 21 in lock cylinder 23.

Lock cylinder 23 carries a series'of tumblers generally indicated at 28 extending from the interior thereof through suitable slots formed therein. Tumblers 28 are so proportioned as to fit within longitudinal channels Ila and Ill; (Figure 3) formed on the opposite sidesv of recess II when lock cylinder 23 is in proper position. Furthermore these tumblers are preferably disc-like in shape, this types of tumbler being more admirably adapted for the present construction due to the small amount of spacerequired therefor. Tumblers 28 and the other apparatus associated therewith within lock cylinder 23 are constructed in the usual manner so that when a key 29 is inserted in a hole 35 in the lock cylinder (Figure l), the key draws all of the plungers down into the cylinder so that none of them extend above the periphery thereof. In thismanner the tumblers are drawn out of channels I la. and I Ib (Figure 3) and the lock cylinder may then be rotated by means of key 29.

A pair of bolt or shackle-dogging members generally indicated at 3| and 32 are located within chamber I2 (Figure 2). Bolt members 3I and 32 have beveled side portions 33 and 34 terminating in shoulders 35 and 35. Shoulders 35 and 36 may fit within notches 38 and 39 located in the opposite sides of U-shaped part I8 and are preferably held in this position by a spring 40 seated within suitable apertures 4| and 42 on the opposing end of the bolts.

As best shown in Figure 2, bolts 3i and 32 are preferably equal in width to chamber I2 and their left-hand sides, as viewed in this figure, are cut away to provide a pair of shoulders 43 and 44. Shoulders 43 and 44 preferably extend from the top to the bottom of chamber I2 as viewed in Figure 2, Extending from the end of lock cylinder 23 is a pair of studs 45 and 46 preferably in registry with shoulders 43 and 44. Notches 38 and 39 are sufficiently deep so that spring 48 may force shoulders 43 and 44 into engagement with the studs.

Thus when the parts are in the position shown in Figure 2 and tumblers 28 extend into channels lid and lib (Figure 3), shoulders 35 and 36 are seated within notches 38 and 39 to prevent righthand movement of part I 8 as viewed in this figure. However, when key 23 is inserted in cylinder 23 so that the cylinder may be rotated as described above, rotation thereof moves shoulders 43 and 44 and consequently bolts 3| and 32 toward each other against the action of spring 40. This action continues until shoulders 35 and 36 are free from notches 38 and 39 after which U-shaped part I8 may be moved to the right and rotated about the axis of end portion I? as described above.

As best shown in Figures 1 and 2, there is located in the upper portion of casing II] a chamber 41, being alongside and to the left of the chamber I2, the chambers 4'! and I2 being separated by an intervening wall portion of the casing structure, that wall portion being the portion earlier above referred to and having a hole therein for receiving the pin 25 (Figures 1 and 2) the upper or open ends of the chambers 41 and i2 and of the hole to have the hole 26 and the chamber I2 communicate into or with it, just as does chamber 41. The opposite sides 48a and 48b (Figure 3) and the end 480 (Figure 1) of channel 48 are preferably beveled inwardly. Immediately adjacent and to the left of channel 48 (Figure 1) and connected therewith is a channel'49 formed on the end of the casing. The bottom of channel 48 has formed therein a chamber 53 preferably having its sides provided with a .U -shaped flange, as by being beveled outwardly to receive the beveled head 55a of a rivet (Figure 2). Chamber 59 extends into channel 48 as does the open end of the U-shaped flan e thereof, and consequently rivet 5I may be slipped therein or removed therefrom with ease.

A cover plate 52 fits within channel 48, being, as shown in Figures 1 and 2, the same length as channel 48, thus covering over the upper openings of chamber 47, hole for the pin 26- (thereby preventing the latter from moving out of the peripheral groove 27 in the key plug 23) and chamber I2, and has its opposite sides beveled outwardly to correspond with walls 485; and 481; (Figure 3) and is thus held in position over chamber 41, hole for pin 25, and chamber I2, thereby. The left-hand end of cover plate 52 has a right angle projection 52a fitting within channel 49 and is also provided with a hole 53 through which rivet 55 extends. Rivet 5! is headed over on portion 525; (Figure 2) thus to hold cover plate 52 in its closing position within channel 48 and prevent sliding thereof.

Before assembly, as described above, I prefer to place in chamber 41 a plurality of spare parts generally indicated at 54. Thus these parts preferably take the form of spare tumblers, pins, springs, and always a small supply of rivets such as rivet 5E. Accordinglywhen the lock is assembled as shown in Figure 2, parts within chamber 47 do not interfere with the successful and efiicient operation of my lock and yet are readily available in case repair becomes necessary.

For example if my lock gets out of order for any reason, it is merely necessary to file off the head of the rivet 5! (Figure 2) and then slide cover plate 52 free from channel 48. The parts 54 in chamber 41 are thus made available and also the lock may be readily disassembled by positioning the casing so that channel 48 is bottom side up. When in this position, pin 26 slides out of the 'casingthus'allowing for the removal of lock cylinder 23 from recess II. The removal of the lock cylinder allows pin 2i to drop out, and, when spring 41! is removed, bolts 3| and 32 may be moved inwardly to permit the displacement of part I3 from the casing. A complete disassembly of my lock'may be thus accomplished with a minimum amount of labor and without damaging any part except rivet 5 I.

After the necessary repairs have been eifected including, if necessary, the use of any of the parts 54, the lock may be reassembled as de-. scribed above and the parts 54 replaced in cham ber 47. A new rivet replaces rivet 5! and may be easily slid into its groove-like chamber 50 (Figure 1) when cover plate 52 has been removed. With the new rivet in position cover plate 52 may be replaced and the rivet headed over, my lock construction then being in as satisfactory condition as when new. Thus not only are spare parts available at all times during the use of my lock, but it may be readily disassembled for purposes of repair without damaging any vital-parts thereof and with a minimum amount of labor. 7

Accordingly it will be seen that I have provided a. thoroughly practical and eflicient construction in which the several objects hereinabove mentioned as wellas many *others are successfully carried out.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing-is to be interpreted as illustrative and not in a limiting sense.
