MINE-CAB CHECK LOCK.
This invention relates" to locking devices, and more particularly to ailock specially adapted for securing mine car checks such as commonly used by miners; i i
One of the main objects o1 the invention is to'provide acheck lock of simple and inexpensive construction wliich will securely hold the checkin such manner as to iiectually avoid its unauthorized removal. A further object is toprovide a lock in which the locking" bolt is magnetically operated thus avoiding any possibility of releasing the check by means of a key'or similar element. Anotherobject is to provide a lock so constructed as .to eflectually prevent release of the check by means of a strip of wire or other material inserted into the lock. Further objects will appear from the detail description. x
In the drawings Fig. 1 is a front view'ott thelock;
Fig. 2 is aback view; i
Fig. 3 is a sectiontaken line 3-3 of Fig. 1;
Fig. lis an inner face view of the back plate;
5 is a planview ot a miners check to be used in connection with the lock;
Fig.6 is a side view of the locking bolt;
Fig. 7 is an end view of the bolt.
The bodv of the lock is formed of a front plate 1 and a back plate 2.
is of approximately semi-circular shape. being slightly greater in extent than a semicircle, and tits snugly into a similarly shaped flange 3 extending rearwardly from plate 1. This back plate is provided, in its inner .iace, with a recess 4; which co-operates with the substantially on inner face of front plate 1 to provide a slot for reception of a check such as that shown in Fig. 5. The main portion of this recess increases inwardly in depth to within a. short distance of a socket 5 provided in the upper portion of plate 2 for reception of the inner end portion of a locking member or bolt 6. This provides a depression 2 at the inner side of check A when the latter is in the lock. and a shoulder 2 adjacent to the lower edge of socket 5. In the event that an at tempt is made to release the check by inserting a thin strip of material between the check and back plate 2, this strip of material will follow depression 2 so as to be deflected away from check A until it encounters The back plate shoulder 2". As the upper portion a of depressions is of just suiiicient depth to snugly receive th'eupper portion ofthe check, the strip of material which encounters shoulder 2' will be deflected upwardly thereby and, upon contact with the inner face of check A, will be turned back upon itself. This serves to effectually prevent the release of check A by inserting' a. strip of materialbietween the check and back plate 2. f
'l-.ock ing bolt 6 is normally held in its inner oroperative position by means of an expansion spring 7 mounted about stem 8 o the bolt and confined between a square shoulder 9 carried by the bolt and the outer end o'l 'a recess'lO extending from the inner lace-otthe front plate .1. shoulder 9 operatingr in this recessjand fitting snugly therein. The nose 11' of bolt 6 has its'inner end beveled at 11 so that, when the check is inserted into the lock it will displace the bolt or force it outwardly against the action of spring 7 until opening a in check-A -registers.with socket 5. 2113"\Vl11Cl1 time the nose portion-of the bolt will passthrougrh opening a into the socket thus securing the check in the lock. Aswill be noted more clearly from Fig. 3, the cylindrical portion socket- 5. the cylindricalv portion of the nose will extend to within a short distance of the inner face of back plate 2.; TlllS effectually prevents displacement oi the bolt so as to release check A by insertion of a thin strip otmaterial between checl' A and plate 1. as
this strip will strike the cylindrical. portion of the nose of the bolt and will be turned back upon itself. As will be noted from Fig. 3. the upper portion of check A is beveled at a so that when the check is inserted into the casing ot the lock this beveled portion will engage between the. beveled surface 11 of nose 11 ot the bolt and the inner face of back plate 2. thus Forcing the bletcly inserted at which time it will be secured by the bolt in the manner described.
This permits ready insertion of the check 7 permitthis to bei done, the bolt is made of A it is, of course,
magnetic material, the body of the lock consisting of plates l and being made of any suitable or preferred non-magi etic nmteriel, such as brass or :ihnninnni. though any other enitnble non-nn1gnetic material may be used for this purpose. A soft iron disc if! is set into plate 1 in alignment and concentric with :1 bore ll! extending from roceso It) and ncconnnodoti11g neck S of the bolt. To relenee the check on energized eleetro-inngnet is placed against or clo-ely mljncenl to disc 113. As the. body ol' the loci; in of nmrmngnctie material. the linen ot nmgnetic force will tend to collect at the central portion of dire 1:3 and to concentrnte upon the neck of the bolt. pulling: the bolt ontwnrdl against the action of spring! 7*, thus rel using the check which will drop ont of the lock or may be readily \\'ilill(l1ll'\\'ll therefrom. Preterobl though not necess:1rily,b:1cl plnte tnperh in thiehnes being thicker at its lower portion. .-o 11 to canoe the lock to set at on onele to the side l of is mine car to which the lock is secured by riretine or nny other snitoble or preferred n'mnner. For this purpose. front plate I is provided. at its lower portion. with inter- :1ll projecting are "l -l which receiverivets 14. these rivets also pnssine' through the ride \rnll lg of the car.
As above indicated. :1nd as will be underetood. changes in detailsv ol coirtrnction and arrangremcnt ot pnrte ot the inyenlion 111:1 be resortedto without departing from the Scope of the Fume. and 'I intend to inelnde all nch \wirintiorin. :18 tall Within the scope of the appended chime, in this application in which :1 preferred form only of my in \ention is disclosed.
