SPECIFICATION forming part of VLetters Patent No. 580,736, dated April 13, 1897.
Application liled Tuly 18, 1896. Serial No. 599,700. (No model.)
To all whom t may concern:
Be it known that I, GRANT W. SMITH, of ONeill, in the county of Holt and State of Nebraska, have invented a new and Improved Time-Lock for Tobacco-Boxes, of which the following is a full, clear, and exact description.
This invention relates to novel mechanism for controlling the supply of chewing or smoking tobacco carried by the user of the weed, the object being to provide a portable receptacle for tobacco that is held closed during predetermined intervals of time by mechanism that releases the lid of the receptacle at the expiration of periodic timeelimits, so as to permit the user to remove a supply of tobacco from said receptacle only when the boxlid is thus automatically released.
The invention consists in the novel construction and combination of parts, as is hereinafter described, and deiined in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar'characters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan View of the novel tobaccoboX closed and locked. Fig. 2 is a reverse plan View of the same. Fig. 5 represents the box-lid open and the glazed dial-cover similarly adjusted. Fig. 4 shows the box opened, the dialcover swung back on its hinge, and an important feature of the improvement exposed by removal of the cover. Fig. 5 is a reverse plan view of a novel time-controlling dial removed from the b'ox. Fig. 6 is an enlarged partly-sectional side view of the improved tobacco-box substantially on the line 6 6 in Fig. 1,showing thelid locked in full lines and released in dotted lines. Fig. 7 is a transverse sectional view substantiallyon the line '7 7 in Fig. 6. Fig. 8 is a transverse sectional view showing a slightly-altered construction of the lid-locking mechanism; and Fig. 9 isa transverse sectional view of the box-lid and supports for the modified locking device on the line 9 9 in Fig. 8, showingl the construction of said device.
There is a receptacle provided, of any suitable material, which is preferably afforded an elongated rectangular form, as indicated in the drawings, the corners and edges at the bottom of the same being rounded to remove sharp angles and adapt it for easy portage in the pocket of the person carrying the device.
The box is divided into two compartments 10 11 by a transverse partition 12,` the compartment lO being designed to hold tobacco of any kindused for chewing or smoking, while the'other compartment contains timeclock gearing 13, adapted to control the release of the lid and cover that close the open sides of the two compartments.
An apertured lid 14 is hinged at one end of the compartment 11 and has a glazing 15 secured over the aperture in it, and below the lid 14 an apertured frame cap-plate 14a is removably secured to the case by screws. A lid, 16 is provided for the compartment 10, having a hinged connection at the end of the same, as shown at a in the drawings, and said hinge is provided with a throw-up spring b, that will cause the lid to assume open adjustment when it is free to do so.
The timeeclock gearing 13 is of any approved construction adapted to drive the dialplate c and note the lapse of hours and fractions thereof that are marked on its top face, the dial in this construction being secured on the cannon-post d of the gearing, below and opposite the aperture in the cap-plate 14, so as to receive correct rotative motion, the regular movement of the dial-plate being indicated by a fixed hand e.. (Shown in Figs.l
1 and 3.) The gearing 13 is driven by a coiled spring f, wound by turning its arbor f in the usual way, said arbor being provided with a thumb-piece that is foldable in a recess in the back wall of the chamber l1, and said recess has a ilat pivoted cover f2, that will close the open recess.
The dial-plate c is suitably notched in its peripheral edge, as best shown at h in Figs. 4 and 5, said notches being each provided with a guard-plate c, that is pivoted on the lower side of the dial near one end of the guard-plate, so that each of the latter-mentioned pieces may be swung to open or close the notch to which itis adjacent.
Each of the cover-plates iis provided with an upright stud or pin m, which pins project from the guard-plates at points near their free ends, up through curved slots in the dialplate c, so .that by moving by hand any of the pins in its respective slot the attached guard- IOO plate may be rocked over or away from the notch 71 it is to guard.
From the lower side and near the free end of the lid 16 a latch-hook n depends, which hook has the sloped wall on its hook portion, faced toward an edge of the locking-bar o, that is within the case 11.
The bar o in one form of its construction is represented in Figs. 4, 6, and 7, comprising a metal strip of proper stability having a T-head o and is pivoted on a projection p from the partition 12, near a side wall of the compartment 11, through a slot in which wall said bar projects and terminatesin a thumbpiece o2. A spring p is projected from the wall 12 and presses the end of the locking-bar o, having the T-head o', away from the dial c.
The bar 0 being spring-pressed at its edge nearest the partition 12, so as to normally remove its head o from the notched edge of the dial c, it will be evident that if any one of the notches h has its cover-plate 'L' swung away therefrom, so as to leave it open, the head o may be vcaused to enter the open notch when the rotative movement of the dial c locates the opened notch opposite the head, the vibration of the lever being manually effected.
It will be seen that the length of the T-head 02 is sufficient to allow its upper member to engage with a notch in the edge of the dialplate c and also impinge upon the ends of such cover-plates i as are swung over the notches they are to guard, so that the bar 0 can only vibrate away from the partition 12 when pressed into an open notch h.
rIhe glazed lid 14 is sufficiently depressed at the edge which is adjacent to the partition 12 when closed to permit the free transverse edge of the lid 16 to lie level thereon when in folded condition, as shown in Fig. 6. The free transverse edges of the cover 14 and cap-plate 14a are notched, as shown in Figs. 6 and 7, so as to avoid contact with the latch-hook n when the latter is caused to enter the compartment 11, the notch a2 of the cover 14 being also shown in Figs. 3 and 4.
- The folding movement of the lid 16 will cause the sloped face of the latch-hook n to bear upon the lower edge of the head o on the locking-bar 0 so that on vibrating the bar against the' stress of its spring p a disengagement of the hook and bar will be effected.
The spaces between the notches h represent periods of time, preferably equal in duration, and it will be seen that the interval between any two of said notches will represent the shortest time for a locked adjustment of the box -lid 16, the complete rotation of the notched dial c defining the longest period of time for a retention of the lid over the compartment 1() in a closed and secured condition.
The manner of using the novel tobacco-box is as follows: The user sets the controlling time mechanism for the lid 16 by closing a suitable number of notches h, the cover-plates z' being moved Over the notches to be closed by manipulation of the studs fm, where they .construction of the device is shown.
project through the time-indicating dial c, so that the free end o of the locking-bar o can be pressed by the thumb-button o2 into a notch 7?. that has been left open. The compartment 10 is sealed and kept closed by folding its lid 16 over the closed lid 14, so that the latch-hook n will engage with the edge of the locking-bar o when the T-head o thereon is in normal retracted position. Now it will be evident that if the gearing 13 is actuated by its spring, so as to correctly measure the lapse of time indicated by the dial c, when the open notch h is thus brought at a predetermined instant opposite the head o of the locking-bar the latter may be caused to vibrate against the stress of its spring by manipulatin g its thumb-button and thus release the hook n, so that the lid 16 may be thrown open by the hinge-spring Z).
It will be obvious that the user of the novel tobacco-box, if he depends solely on the contents of said box for the tobacco he chews or smokes, will be enabled to control the extent of such use of the weed by arranging the mechanism that has been described so that access tothe interior of the compartment 10 can only be had at times previously determined by the tobacco-chewer, who desires to control his appetite therefor and resist inclination to an inordinate use of the same.
It is well known to habitual tobacco chewers and smokers that the use of the same increases involuntarily, so that the tobacco is chewed and smoked at more frequent intervals of time than would be if the user was caused to realize the excess of consumption by inability to satisfy the craving unchecked.
The improved tobacco-box is designed to enable an inordinate chewer or smoker of tobacco to limit use of the same by causing him to wait the lapse of a predetermined interval of time before he can take a fresh chew or ll his pipe, and by gradually increasing the length of time between such acts of indulgence the habit of tobacco chewing and smoking may be greatly restricted and cured in the course of time, as its effect on the system is gradually diminished.
A small pinion on the upright shaft d', which has a thumb-piece exposed above the cover-plate 14, is meshed with the gearing 13, so as to enable the user of the improved tobacco-box to set any figure on the dial c op- -posite the hand e by a rotatable movement of the cannon-post. d when such adjustment is desired. Y
In Fig. 8 of the drawings a slightly-altered The locking-bar s for the device represented in Figs. 8 and 9 is held in an upright position by pivoting its lower end onran ear s', that in this case projects projects from the transverse wall 12 of the compartment 11, a further support therefor being affordedy by the laterallyextending rod o, that in complete form extends through a slot in a bracket-plate p, that vprojects from a side wall of the compartment,
as indicated by dotted lines in the figures mentioned.
On the side of the upright locking-bar s a latch-dog u is pivoted, the pivot engaging a limb s2 of the dog that projects therefrom so as to lap upon the side of the bar, whereby the dog is supported to rock between the inner edge of the locking-bar and the edge of the dial-platee, that is notched, as before eX- plained, and has the cover-plates z', provided to guard said notches h.
The dog u is provided with a contractile spring n, that is connected to its lower end at u,and also to a projection S3 from the ,bar s, the pull of said spring being adapted to rock the toe of the dog u toward the edge of the dial c until checked by the impinge of a depending lug u2 on the dog upon the adjacent edge of the upright locking-bar s.
In the operation of the modified form of the device the lid of the tobacco-holding compartment is retained in closed adjustment by the latch-hook fn on the lid 16 during the rotatable movement of the 'dial c necessary to bring an open notch thereon opposite the toe of the dog u, so that the latter may be rocked into said open notch by movement of the rod 0, and correspondingly rock the locking-bar s away from the engaged latch-hook n, so as to permit the spring-hinge of the lid 16 to elevate it, and thus expose the contents of the tobacco-holdin g compartm ent of the improved tobacco-box.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a device of the construction described, the combination with a box having two compartments therein, a hinged lid for each compartment, and a depending latch-hook on one lid adapted to enter a compartment when the lids are closed, of clock-gearinghaving a timeindicating and time-controlling peripherallynotched dial on a rotatable post of said gearing, and a locking-bar for the latch-hook, adapted to enter an open notch of the dial and thus release the latch-hook, and means for closing one or more of the notches in said dial, substantially as described.
