COMBINATION'LOCK.
No. 470,438. Patented Mer. 8, 1.892.v
UNITED STATES TIMOTHY XV. MCGRATH, OF BROOKLYN, NEY YORK.
COMBINATION-LOCK..
SPECIFICATION forming part of Letters Patent No. 470,438, dated March 8, 1892.
Application tiled August '7J 1891.
certain new and useful Improvementsin Comj bination-Locks, of which the following is a specification.
My invention relates to that class of locking ,A
devices known as combination-locks, in which the bolt is unlocked throughthe medium of a certain combination of letters, marks, or numbers.
The object of my invention is to provide a simple, secure, and durable lock consisting of few parts and which will be very cheap to manufacture.`
Thefinvention consists in the novel details of improvement and the combination of parts that will be more fully hereinafter set forth, and then pointed out in the claim.
Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure lis a partly-broken perspective View of a box having my improvements applied. Fig. 2 is an inverted plan view of the cover. Fig. 3 is a central longitudinal sectional view showing the parts in the locked position, and Fig. 4 is a face view of the locking-disk.
In the accompanying drawings I have shown my invention as applied to a box A to hold its cover B closed.
My invention contemplates the combination of two or more, preferably two, of said locking devices, as shown in Fig. l, which consist ofthe disk D, shown carried on the spindles a, the dial-knobs h being rigidly connected to said spindles. Each dial-knob is provided with a marked or numbered portion or dial f, formed upon or rigidly attached thereto, so that when the dial-knob b is rotated the dial fand parts a and D revolve. The disks D are cut away at D2on one edge to reduce their diameter at that point, and the remainder D3 of the periphery of the disks is to enter a groove or engage a projection g, (shown on the door or cover B or the part to be held,) whereby the latter cannot be moved unless the cut-away parts of the disks both coincide with the groove or projection g.
e is a stationary dial-plate, shown carried on the box Al and having on its face two lettered- Serial No. 401,978- (No model.)
or numbered dials and being provided with two apertures e4 to admit the spindles a. By this means the dial-plate is held in position by the spindles only without extra parts, whereby a saving in expense is effected. This stationary dial plate, although preferably made in one piece, may be made in two plates, having one dial e2 on each plate.
The spindles a are shown journaled in the side of the box A, and the disks D are concealed within the box, while the operating knobs b are on the outside. I prefer to provide the knobs b with a less number of figures or characters than the dial-plates e, so that only one combination of figures can be made at once, the others remaining out of line. By thus graduating the stationary and rotating scales differently an indefinite number of Vcombinations can be made and the combinations of the spindles can be entirely different, and this with the use of but asingle scale on each spindle and stationary dials for each. If only one scale were used, as heretofore, only a number of combinations correspending to the number of figures on the single scale could be used, thereby greatly limiting the number of combinations possible to make; but by having a stationary and a rotating scale a Very great number of combinations can be made.
To open the lock, lthe disks D D must be turned by rotating the knobs h until the correct number combinations are reached upon the dials, when the cut-away parts Dz'on both disks will coincide or be parallel in line with the groove or projection g, and the groove or projection g will be then completely disengaged from the disks and the cover be free to open. A partial revolution either to the right or left of either or both disks then relocks the parts, as the part D3 then encounters the groove or projection g.
It will be observed that by using the disks D correspondingly cut away at D2 both the latter places must coincide in line with the obstruction on the cover before the latter will open and that if either disk is turned slightly the cover will be locked.
The construction of parts is very simple, yet effective in use, and the cost to manufacture is very slight, so that the locks can be placed IOO on cheap articles,such as scholars companions, (peneil-boxes,) and cigar and stamp boxes.
It Will be understood that when I speak of a boX audits cover I mean any device to which the invention is applicable, as it is capable of use on drawers, doors, Windows, and many other articles. It is evident that the disks could be carried on the cover and the obstruction g be on the box with the same result.
Having now described my invention, what I claim is- In a combination-lock, the combination of two or more lock-disks D, each having a spindie a, and dial-knob b, having scales, the parts D and bbeing rigidly connected together and each capable of being rotated independence of two Witnesses, this 3d day of August, 3o
