AUGUST Menrnurni., or cirroAGo, ILLINOIS,
Application filed February 1, 192,3; Serial No. 6169265. n
To alla/)hom it may concern.'
Be it known that I, AUGUST MAN'rnU'r-EL, a citizen of the United States, and a residentof the cityl of Chicago, county oit Cook, andv State of: Illinois, have invented certain new and useful improvements in Locks, oiwhicli the tollowing is a specification.
My invention relates` to improvements in locks, and has tori its principal object the provision or an improved constructiony ot this character which will be highly eliicient in use and economicalin manufacture.
4Among other objects of the invention is theprovision of certain elements which will greatly facilitate the manufacturing of the invention and the assembling of the same.
Other objects will appear hereinafter.
The invention consists 'in the combinationsv and arrangements oi'' parts hereinafter described and claimed. l
The invention will be best understood by reference to the accompanying drawingsV forming a part of this specification, and in which, d Y

Fig. ll, is a sectional View of the same taken substantially on line 114-11 of Fig. 10;. and l Fig. l2, is an enlarged sectional view of the. same takenv substantially on line 12-12 of-Fig. V10. l
Referring to the drawings indicates a with an enlarged head 23 adapted' to seatv within an annularv recess 2li formed inthe lock barrelr 2O.l
The construction solar described is eln-v bodied in approved locks of the character" herein set forth and reference to such parts are only madellor the purpose of bringing out the legitimate combination oliI the presi' ent invention. i'
The tumbler hol-der 22, as shown in Fig. 5, n
is provided with longitudinally extending slots 25 andl leg portions 26 arranged at one end. thereof, the latterv being viorriied at an; angle o :t approximately forty-tive degreesf with respectV to each other. The cap QSQFig. Ll, ol? the tumbler holder is provided with notches 29 for the reception of the leg portions 26. The lock tongue 30'is formed integral on a disc 31 having opening'sSQ cut theretlnfough, through which reduced por-iy tions 34; of the legs 9.6 project. The disc 3l is mounted over the cap 28 and when such position theprojecting.portions 34! are riveted over, securing` the disc in such yposition. lThe lock tongue is adapted to unction with a cooperating lock member `(not shown) Voli any approved Formed inthe cap 28 and the opposite end oli* the tumbler holder 24 are registering key slots and through which the key' is inserted.
The tumblers 35, illustrated in Fig. 7, are formed with slots 36 for the passage of the key and are mounted in the tumbler holder 22 with their opposite extremities projecting through the opposite slots 25. f
fn manufacturing the locl,'the tumblers are arrangedl in pile form with their eri# tremities projecting beyond the periphery of the tumbler holder, Fig. 9, and with their key slotsBG registering with .one another. The key 35i is used as a pattern for lcutting the tumblers so as to function only with that particular key. ThisA is accomplished by inserting the hey within the` tumbler holder and cutting vthe extremities ofthe tumblers liush with the periphery of tumbler-holder with the keyy inserted therein. Due to the irregular side edges of thekey the tumblers when the is`V withdrawn romthe tumbler holder will bel irregularly construction.
