UNITED STATES PATENT OFFIC DANIEL J. CABLE, OF PITTSBURG, PENNSYLVANIA.
SPECIFICATION forming part of Letters Patent No. 517,729, dated April 3, 1894. 7' Application filed April 28, 1893, Serial No. 472,157. (No model.)
To all whom it may concern.-
Be it known that I, DANIEL J. CABLE, a citiburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered a, new and useful Improvement in Locks, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1, is a perspective view of a book provided with my improved lock. Fig. 2, is asimilar view, partially broken away, showing the locking bar withdrawn and the book thrown partially open. Fig. 3, isa plan view of the lock, showing the operative parts in dotted lines, as in a locked position. *Fig. 4, is a vertical longitudinal section on the line a: a: of Fig. 3. Fig. 5, is a horizontal section on the line y y of Fig. 4. Fig. 6, is a similar view to Fig. 3, but showing the operative parts in dotted lines, as in a position to allow the locking bar to be withdrawn- Fig. 7 is a similar view to Fig. 5, showing the dial stems in register with the slots and thelocking bar withdrawn, as when the hasp plate is to be released. 'Fig. 8, is a plan view of the hasp' plate. Fig. 9, is a perspective view of the locking bar. Fig. 10 is a perspective view of the hasp piate. Fig. 11 is a perspective view from beneath, sh owing the lock case, the locking bar, and the hasp plates in an operative position. Fig. 12, is a perspective view of the dial. Fig. 13 is a perspective view of the dial stem. Fig. 14 is a perspective view of a securing plate to be used when it is desired to detach the entire lock. Fig. 15 is a vertical cross section on the line zz of Fig. 3.
Similar numerals of reference refer to like parts wherever used throughout this specification.
My invention consists of a combination lock to be applied to books, satchels, pocket-books, or other similar articles, and it comprises essentially-a locking case or shield having openings in theside for the insertion of a hasp 1 plate; a plate provided with downwardly projecting lugs for engaging the hasp plate, capable of longitudinal movement within the case, controlled by one or more dial stems passing through the openingsin the movable the case, in engagement with a retaining bar ,or plate, permanently attached to the article.
. Referring now to the drawings, 2 is the lock case riveted, or otherwise secured to one cover, 3 of a book, to the other cover 4 of which is similarly secured the hasp plate 5, provided with inwardly turned flanges 6 andthe slots 7.
Within the lock case 2 is located the locking 7 7 bar 8 which is held upward against the under s de of the case by the rivet heads 9 at the lower ends of the dial stems 10, which stems I pass upthrough proper openings in the case 2 and are riveted or. otherwise secured to the dial buttons 11, on the upper face ofthe case. The locking bar 8 is provided through its central body portion with openings,, made round at one end 12 to allow the full diameter of the dial stem 10 to pass therethrough, and at the other end the opening is somewhat longer and narrower as at 13 to allow thejthinner flattened portion 14 of the stem to enter it, only when it is exactly in register as shown in Fig. 7. It will be seen that when thus in register the locking bar may be withdrawn, but when not so in register, its withdrawal will be prevented, as illustrated in Fig. 5. In the drawings I have illustrated three such openings and stems and it is obvious that any number desired may be employed, thereby increasing the number of combinations as each dial is located in a different relative position on therefore must be set to its own proper position, and when all the dials are so set, the flat parts of the stems 14 will be in register with theopenings 13 in the bar. 1 have shown these openings as leading off from the opening12 somewhat to one side, as in a central position the flattened part of the stem would have to be in its center, and would therefore allow the opening to come into register with it in two positions of the dial which I desire the stem, and
to avoid. I do not, however, wish to limit myself to this way of cutting the slots, as I may find it advantageous to locate them in line with the center of the bar in some constructions of locks, varying according to circumstances.
In the side of the case adjacentto the hasp plate are the slotted openings 15 immediately below the lower edge of the locking bar and the flanges 6 are designed to enter these openings, and the slots 7 to be engaged by the downwardly projecting lips 16 on the locking bar as indicated in dotted lines in Fig. 5 and shown in perspective in Fig. 11. When in such position the dials may be turned out of combination, throwing the fiattened part of the dial stem across the slot and until again put in register, the locking bar will be immovable, securely holding the hasp plate and preventing its withdrawal.
For the purpose of allowing the lock to be made detachable I may employ the securing plate shown in Fig. 14.- which is provided with the openings 17 into which may be inserted the hooks 18, formed integral with the case, furnishing a secure attachment when the hasp plate is locked, but permitting of the easy removal of the entire look when not in use.
Any number of numerals maybe employed and the registering point 19 may be located where most convenient to suit the dilferent uses to which the lock may be put.
In the drawings I have shown the lock set to the combination 4t-1-1. And it is obvious that in any other combination it will not open. Divisions, such as halves and quarters between the numbers may be readily employed when the diameter of the dial will allow of it.
I am aware that it is not new to make locks in which a series of disks are brought into register with a lockingbar but such construction does not form a part of my invention.
The advantages of myinvention will be ap preciated by those skilled in the art. It is simple, effective, cheap, and not liable to get out of order; and is applicable to many cases where locks of other construction could not be used.
Having described my invention, what I claim, and desire to secure by Letters Patent, is-
1. A look, comprising a case or shield, having openings in the side for the insertion of a hasp plate; aplate provided with downwardly projecting lugs for engaging the hasp plate, capable of longitudinal movement within the case, controlled by one or more dial stems, passing through the openings in the movable plate, and provided with narrow portions designed to register with slotted extensions of said opening, and having at their upper portions numbered or lettered dials, designed to be set to a combination, substantially as shown and described.
2. A look, comprising a case or shield having openings in the side for the insertion of a hasp plate, a plate provided with downwardly projecting lugs for engaging the hasp plate, and a narrower forwardly extending upturned linger piece: capable of longitudinal movement within the case, controlled by one or more dial stems, passing through openings in the movable plate, provided with narrower portions designed to register with slotted extensions of the openings, such openings being located to one side or the other of the center line for the purposes described: the dial stems having at their upper portions numbered or lettered dials, designed to be set to a combination by registering with a fixed point, substantially as shown and described.
3. In combination with a book, satchel or other similar article, a case rigidly secured to one side thereof, provided with a locking bar capable of longitudinal movement therein, such movement being controlled by one or more dial stems passing through openings in the bar, the stems having narrower flattened portions designed to enter longitudinal extensions of the openings in the bar and provided at their upper portions with numbered or let-' tered dials, designed to be set to a combination, and a hasp plate secured to the other side of the article provided with inwardly and forwardly shaped lugs designed to enter open ings in the side of the case and to be engaged by downwardly projecting lugs on the locking bar, substantially as shown and described.
4. In combination with a book, satchel or other similar article, a case carrying a locking bar capable of longitudinal movement therein, such movement being controlled by one or more dial stems passing through openings in the bar, the stems having narrower flattened portions designed to enter longitudinal extensions of the openings in the bar and provided at their upper portions with numbered or lettered dials designed to be set to a combination: the case being provided with downwardly projecting hooks, removably attached to a retaining bar or plate secured to one side of the article, and a hasp plate secured to the other side of the article, provided with inwardly and forwardly shaped lugs, designed to enter openings in the side of the case, and to be engaged by downwardly projecting lugs on the lockin g bar, substantially as shown and described.
In testimony whereof I have hereunto set my hand this 27th day of April, 1893.
