UNITED STATES PATENT OFFICE.
CHARLES E. BLECHSCIIMIDT, OF BELLEVUE, KENTUCKY, ASSIGNOR TO THE VICTOR SAFE AND LOCK COMPANY, OF CINCINNATI, OHIO.
SCREW-DOOR SAFE.
SPECIFICATION forming part of Letters Patent no. 645,448, dated March 13, 1900.
I Application filed December 4, 1899. Serial No. 739,109. (No model.)
To all whom it may concern:
Be it known that 1, CHARLES E. BLECH- SCHMIDT, a citizen of the United States, residing at Bellevue, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Screw-Door Safes; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which forma part of this specification.
In Letters Patent No. 629,7 64,issued August 1, 1899, to The Victor Safe and Look Company, of Cincinnati ,Ohio, as my assignee, I have shown a screw-door safe having a peculiar mechanism for advancing and retracting a set of sliding bolts, their retraction being effected by a time-lock attachment. Said mechanism is perfectly reliable when a door is operated in a proper manner; but in attempting to force it open by wedges or other violent means the bolts or their connections are liable to bend, and thus render it impossible for the timer to perform its duty. Therefore to render the mechanism uniformly reliable no matter how many of its parts may be bent I now arrange it in such a manner as to enable the timer to liberate an auxiliary springactuated device. By such an arrangement the power necessary for withdrawing the bolts from their respective keepers is produced by said auxiliary device, thereby relieving the timer from this service, as hereinafter more fully described.
In the accompanying drawings, Figure 1 is an elevation of the inner end of a screw-door safe provided with bolt-operating mechanism similar to that described in said patent. Fig. 2 is an elevation of the lower portion of said door, a timer being applied thereto, the timercase sectioned, and the auxiliary device locked. Fig. 3 is a similar elevation, but showing the auxiliary device unlocked and the bolts retracted. Figs. 4and 5 are enlarged vertical sections of a combined trip and stop in two different positions. Fig. 6 is an enl'arged vertical section of part of my mechanism, said section being taken at the dotted line Z Z of Fig. 2.
The front wall A of the safe has secured to it a ring B, provided with a female thread C, wherewith is engaged a male thread of a ring E, attached to the inner side of the door F, said male thread being indicated in Fig. l by the dotted circle D. Cut across this ring E are grooves e, that guide sliding bolts G,.pivoted to angular links H, the latter being coupled at h to an oscillator I, pivoted at i to the door F and normally held against a stop f by a spring J.
M is ashifter-bar of any approved timer, housed within a case N.
' O is a transverse bore in the door-ring E to admit a push-stem P, whose outer end is beveled off, while its inner end is coupled to a lever B, pivoted to the safe-door at r.
S is a spring that maintains said lever in its normal position. These devices P R S constitute the combined trip and stop above referred to.
b are keepers in the fixed ring B to admit the advanced bolts G for the purpose of looking the door and preventing it being turned either to the right or left until the timer liberates the operating mechanism.
All the above-described parts are arranged to operate in precisely the same manner as the correspondingly-lettered devices shown in the patent previously referred to, and for this reason furtherexplanation of them is unnecessary in this specification.
Coming now to a description of the novel features of my present invention,T represents a plate or disk that conceals the aforesaid mechanism and has the timer-case N secured to it. This plate is of the same diameter as the ring B and is slotted att to permit free passage of a coupling-pin h, projecting rearwardly from one arm of the oscillator I, as shown in Figs. 1 and 6. Again, in addition to passing through this slot t said pin traverses a slot u of a link U, pivoted to the plate T at 'v and having a side lug v. \V is a trigger, also pivoted to said plate and having one end so shapedas to engage the lug '0, while its other end enters a notch or slot on of the timer shifter-bar M.
X is a comparatively-stiff spring for operturned by the spring J as far as the stop f will permit, at which time the pin it is at the upper end of slot u, and trigger WV is en gaged with the lug 'v. Furthermore, the shifter-bar we now occupies the position shown in Fig. 2, and assuming, as a matter of course, that the timer had been properly set before closing the door it is evident that the bolts will remain advanced until said timer goes ofi. Such action of the timer shifts its bar M m over to the position shown in Fig. 3, thereby disengaging the trigger W from the lug o and permitting the spring X to exert its power upon the lever V. Consequently the free end of this lever is depressed and link U pulled down until the pin h strikes against the bottom of slot 15, which act so rotates the oscillator I as to retract all the bolts, thereby unlocking the door and permitting it being screwed open. This retracted position of the bolts is indicated in Fig. 3 by the dotted lines G, while the dotted lines G in Fig. 2 indicate that said bolts are advanced to the same position as in Fig. 1.
' From the above description it is evident that the powerrequired to retract the bolts is afforded by the stiff spring X, and therefore the only duty of the timer is to disengage the trigger W from the lug 'v,which liberation is readily effected by a very weak spring.' Hence if the bolts G should be bent in attempting to force the door open by driving wedges in between it and the safe-casing, the spring X will insure the positive retraction of said bolts at the appointed hour. Finally, the longitudinal slot u of link U enables the free end of lever V to be swung up, so as to engage its lug o with the trigger W and without turning the oscillating spider I, as it must be arrested by the stop R, as shown in Fig. 5,when said spider is coupled to the timer attachment.
I claim as my invention- A screw-door safe provided with an oscillator that automatically advances and retracts a set of belts, in the manner described, a timer shifting-bar M m; a trigger W operated by said bar; a leverVo,wherewith said trigger engages; a spring X, that operates said lever; a slotted link U it, connected to said lever; and a pin h projecting from said oscillator, and traversing said slot u, all as herein shown, and set forth.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES E. BLEOHSOHMIDT.
