UNITED STATES -PATENroFF1c-1a HEBER o. GRIFFIN, oF FRANKLIN rants, NEW-HAMPSHIRE, ASSIGNOR trof THE GRIFFIN Loo COMPANY, or SAME PLACE.
COMBlNATlQ N-LOCK.
SPECIFICATION forming part ofLetters Patent No. 381,068, dated April 10, 1888. y Application filed December 17, 1887. Serial No. 258.158. (ModeL) 10 combination-lock, and is designed to facilitate the finding by the operator of the pointfrom which to compute the combination, commonly called zero. i
The object 1 to enable ,the operator to find zero wholly by the sense of feeling, as well as count the revolutions of the knob. 'This is readily accomplished by the device illustrated in the accompanying drawings, and clearly described in thefollowing specification and 2C claims, of which said drawings form an inseparable part.
Figure 1 is a perspective view showing a portion of the edge and front or outside of a door to which a lock and my improved operating-spindle are attached. Fig. 2 is a similar view having a portion of the outside of the door broken away and exposing to view the lock-housing. Fig.3 is a sectional elevation showing a portion of the'lock housing, its rotative tumblers, andmy improved operatingmy improved operating-spindle.
spindle as when in its normal position. Fig. 4 is a similar View showing the improved operatingspindle as when at zero. Fig.5 illustrates a simple modification of a portion of Similar reference letters indicate corresponding parts throughout the various views. A-is a portion of the inner part of a lock- -housing,and a is an integral journal on which 0 the rotative tumblers rest, which also serves as a bearing for myimproved operating-spindle, through which it passes. I
The latter is formed in two parts, B 0, one end of the spindle portion B being adapted to enter the knob portion 0, which is bored to form a loose fit, and rendered capable of longitudinal .movement thereon in the following manner, viz: The spindle portion B is slotted at 'b, and the knob portion 0 is provided I with a hole, 0, which passes throughit transversely and a little to one side of its longi-Q tudinal center, accommodating a pin, a, which L passes throughthe said slot in'the spindle portion B. .A spiral spring, D, maybe placed in the chambered' portion of the knob portion 0, bearing against the outer end of the spindle I portion 13, as shown, and thus hold said knob pdrtion O as shown in Fig. 3i. e. ,;with the 'pin clbearingagai'nst the outer end of the slot 0 of the said-spindle port-ion B-=-for apurpose to be hereinafter explained. The said spindle portion B may be shouldered at 1) against the lock-housing A, or otherwiseprevented from further'entering the lock;
In connection with my improvementitis necessary that a'stoppiece, a, be provided on the lock-housing A at 'a-point to contact with;
a slot, 0", formed for'th'is-purpose inthe inner face of the knob'portionO ofmy improved spindle, which designates the starting-point for computing the combination. Thisstoppiece a may be semicircular, asin Figs. 2, 3, 4, or a thin projecting lug, as in Fig.5, provided always that the slots" of the knob-pop tion 0 shall be of corresponding length, in
order that there may be no'lost motion when" I said, knob portionis engaged with said-stop piece. a.
To find zero by the use of thisimpr oved q spindle, it is but necessary topressthe knob portion 0 inward while rotating the same, and the moment the slot 0 and stop-piece a are opposite the knob portion yields tothe pressure and receives the said stop-piece a,"as in Fig. 4.. Then by relieving the pressure theknob putation. t
Having described my improvement, what I' claim, and desire to secure by Letters Patent of the United States, .is-- y 1. The combination, with a combinationloc'k, of an operating-spindle composedof two parts, one movablejlongitudinally upon the 8" 7 portion of the spindle may be turned forc'omother and rotative nl ,in unisontherewith,
and a suitable spring wherebysaid movable member is held in itsnormal position, sub stantiallyas and for the purpose explained.
2. The combination, with the lock-housing having a projection or stop-lug near the op-.
crating-spindle, thefsaid spindle, a knobor roe handleportion for rotating the same capable In testimony whereof I afiix my signature in of longitudinal movement thereon, and propresence of two witnesses. 4 vided with a slot for engaging the stop-lug on 1 T said lock-housing, andasuitablespring where- HEBER GRIFFIL by said movable knob is held normally clear Vitnesses: of the said stop-lug, all substantially as and JAS. E. BARNARD, for the purpose set forth. DANIEL BARNARD.
