Application filed July 10, 1914. Serial No. 859,120.
. numbering machines, and more particularly to devices for preventing tampering with the numeral wheels of such machines by unauthorized persons.
In the drawings I have shown in Figures 1 to inclusive, the application of my invention to a hand numbering machine of a type well known in the art, while Figs. 6 and 7 show the invention as applied to a numbering machine of the sort which may be used in connection with a power press.
The invention consists of the elements, combinations and arrangements of parts hereinafter described, and the advantages resulting therefrom will be apparent from the description; while the scope of protection contemplated will appear from the claims.
In the accompanying drawings, which are to be taken as a part of this specification, and in which I have shown embodiments of the invention as at present preferred, Fi g. 1 is a front elevation of a numbering machine of the hand-operated type, with my'invention applied thereto; Fig. 2 is a side elevation of the subject-matter of Fig. 1, look ing from the right, the main frame being broken away; Fig. 3 is a rear elevation; Fig. 4t is vertical cross sectional view taken on the line 44 of Fig. 8 and looking in the direction of the arrows, the parts. being shown in their normal positions; Fig. 5 is a view similar to Fig. 4, but showing the parts in the depressed or printing position; F ig. 6 is a front elevation with parts in section, illustratin a numbering machine applied to a power press and including a correspondingly modified embodiment of my invention; and Fig. 7 is a vertical cross sectional view taken on the line 7-7 of Fig. 2.
Referring to the devices shown in Figs. 1. to 5 inclusive, there is, as usual, a main frame 1 having a general U-shape, and provided with the usual cutout base plate 2. On the top of the frame 1 there is provided a sleeve 3, within which works a reciprocatheads on the inside of the frame 1.
ing rod 4, whose upper end is provided with a handle 5 whereby it may be depressed against the force of a coiled spring 6 mounted within the sleeve 3 and surrounding the rod 4. At the lower end of the rod 4: is carried a printing frame 7, having studs 52 extending from the sides thereof and adapted to slide in the vertical grooves 8 on the inner sides of the arms of the frame 1. The printing frame carries a shaft 9 on which are mounted a series of numeral wheels 10, at the side of each of which is formed a ratchet wheel 11 having teeth adapted to be engaged by a spring-pressed de'tent-pawl 12, whose office is to prevent the wheels 11 from rotationeXcept in one direction, and also to prevent over-rotation thereof. The several detent-pawls 12 are mounted on a common supporting shaft 12 which extends acrossthe printing frame. There is also pivotally mounted on the shaft 9 an actuating pawlframe 14 having a shaft 15 extending across it on which is mounted a series of actuating pawls 16 adapted to engage the ratchet wheels 11 to advance the numeral wheels in the usual manner. Projecting from each of the side walls of the pawl-frame 1 1- is a pin 17, which engages a cam slot 13 formed in each one of a pair of plates 18, which plates 18 are. secured at their upper ends to the inside of the walls of the main frame 1, as by screws 1919, these screws having their The lower ends of the plates 18 are secured by screws 2020, the heads of which are countersunk on theoutside of the walls of the main frame 1. The heads of the screws 20-2O are preferably provided with spanner holes, so that a special tool'is required to unscrew them. When the handle 5 of the machine is depressed, the pawl-frame 14 is rocked 011 the shaft 9 by reason of the movement of the pins 17 in the cam slots 13 in the side plates 18. This causes the pawls 16 to move back over one tooth of the several ratchet wheels 11, as shown in Fig. 5, without accomplishing any movement thereof, but as the handle moves upwardly again, under the influence of the spring 6, the pins 17 again engage the slots 13 and rock the pawl-frame 1 1 back to its normal position, shown in Fig. 4, the pawls 16,01- at least one or more of them, having, in the meantime,
engaged and moved one or more of the ratchet wheels 11 and thereby caused the nu- Patented Oct. as, rare.
meral wheels 10, or one or more of them, to progress n the usual manner. The mechanisms thus farrdescribed are not, in them- The result is that the ratchet wheels 11 and consequently the numeral wheels are locked in position, and while the numeral wheels are of course now accessiblefrombelow the machine through the opening in the base 2, they cannot be moved or tampered with.
7 Between the walls of the main frame 1 there is also mounted an inking frame 21 which is generally U-shaped, and the side walls of which are provided with slots 53 (see Fig. 2) in which are engaged the studs 52 in the sides of the printing frame 7. The side walls of this inkingframe 21 are notched to v form projecting lugs 22 bent out at right angles,- and between these lugs 22 and the bottom of the frame 21 there is also an ink pad 23 secured to a holder 24, which holder 24 has at its forward'end an upturned flange 25 andat its rear end a spring clip 26 adapted to engage in a hole in the bottom of'the inking frame 21 to lock the ink pad holder 24 in position, as shown in Figs. 4 and 5. The inking frame 21is provided with pins 54 extending'from each side, to which are connected the endscof arms 55, the other ends of the'said arms being pivoted to screws 56 in'the sides of the frame 1. The arms 55 are furtheroconnected to the: studs 52, by means of arms 57, which are pivoted to the i studs 52 and'to the. arms 55 as at 58. The
screws 56being mounted in the frame 1 constitute pivots for the arms 55, and when the handle 5 is depressed and the printing frame 7 moves downwardly, it carries the studs 52, on which are pivoted the arms 57,
which in turn are connected tothe'arms 55.
The inking frame 21 being pivotally connected to the arms 55 by means of the pins 54, causes the frame to move down and swing out from under the descending printing frame, as shown in Fig. 5, the studs 52 forming the pivots for the inkingframe 21, the said studs engaging in the slots 53 as described, so as to permit of the downward travel, as well as the upward swing.
From the description of the mechanism it will be evident that it would be possible to tamper with the numeral wheels 10 when the machine is normal, as the detent-pawls 12 are not in that position locked against the ratchets 11. Therefore, to prevent access to the numeral wheels when the position is in its normal position, as in Fig. 4, there is provided a shield 27, secured as by means of rivets 28, to the front edges of the cam plates 18. This effectually prevents access from the front of the machine, and to prevent access from the rear, there is provided a shield 29, secured by rivets 30 to the rear of the printing frame 7 and substantially closing the same. Access from the bottom when the machine is in its normal or unlocked position is prevented by reason of the fact that'with the construction shown and described, it is impossible to remove the ink pad holder 24 from the inking frame, except when the machine is in a printing position, as in Fig. 5, because the holder 21- can only be removed by a straight vertical pull, as shown by the dotted lines of Fig. 5, and such a vertical pull can only be exerted when the machine is in the printing position and when consequently the numeral wheels are locked, so that it makes no difference whether the numeral wheels are exposed or not. The holder 24 cannot be removed when the machine is in the normal position, as it is in Fig. 4, because the upturned flange 25 on the holder is held by the bottom of the printing frame 7. Consequently, with my invention the numeral wheels are substantially shielded so long as they are not in printing position, and when they are in printing position they are locked. In addition to the precautions already enumerated, I prefer to provide the screws 20 with special heads, requiring a special tool to remove them, thus to prevent the unauthorized moval of the plates 18 to which the shield 27 is riveted.
In the embodiment of the invention. shown in'Figs. 6 and 7, a numbering machine is rotatably mounted on a stationary shaft 31, which is secured to some part of a power press, not shown. The position of the shaft 31 is, however, such that when the machine is rotated in a manner hereinafter described, the numeral wheels will engage the periphery of a platen roll 41 mounted in the press, and register upon a strip of paper which is fed through the press the number set up on the numeral wheels. lhe numbering machine in this case consists of a frame 32 having a boss 33 projecting from the rear wall and forming a bearing on which the machine rotates on the shaft 31. Means for rotating the frame 32 is provided by securing to the rear wall of the frame, as by means of a screw 34, one part of a clutchmember 35 adapted to be engaged by the other part 36 of the clutch which is slidahly mounted on the shaft 31 and has connected to it, by means of a key 37, a pulley 38 driven by a belt 39, a forked lever 40 engag ing the member 36 to provide means for operating the clutchmembers 35 and 36. The numbering machine has mounted between the side walls of the frame 32 on a shaft 109 a numbering head comprising a series of numeral wheels 110, the printing surfaces of which are formed in an arc whose center is the center of the shaft 31. The numeral wheels 110 are provided with ratchet wheels 111, as usual, adapted to be engaged by detent-pawls 112, and there is also mounted on the shaft 109 an actuating pawl frame 114 which carries a shaft 42 on which are mounted actuating pawls 116 which engage the ratchet wheels 111. The pawl-frame also carries a second shaft 115 which, in its function, is analogous to the shaft 15 in the hand numbering machine previously described in that it serves as a lock for the detent-pawls 112 when the numeral wheels are in the printing position. The actuating pawl frame carries a knob 43 adapted to engage a cam 44 on the shaft 31 and secured thereto by a pin 45. This knob 43 revolves around the cam 44, and, in the position of Fig. 7 the knob 43 and consequently the pawl-frame and the actuating pawls 116, are held up by the retractive springs 46, which are attached between the pawl-frame 114 and the main frame 32, and the shaft 115 overlies the detents 112, keeping the same in locking engagement with the ratchet wheels 111, so that the numeral wheels cannot be moved. The cam 44 is of course shaped so that the upward swing of the pawl-frame under the influence of the springs 46 is permitted. When, however, the printing head revolves around the shaft 31 the knob 43 comes in contact with the cam surface on the cam 44, and the pawl-frame 114 and consequently the actuating pawls 116 are swung downwardly on the pivot 109, so that one or more of the actuating pawls 116 will act upon the corresponding ratchets 111 to advance one or more of the numeral wheels, this advance being completed before the printing head again reaches the printing position, and when this printing position is reached the cam again permits the springs 46 to pull the pawl-frame back into the position shown in Fig. 7 where it looks the detents 112 against the ratchets 111, thereby preventing any tampering with the numeral wheels while the latter are in the printing position. Any tampering with the numeral wheels while the apparatus is in other than printing; position is prevented by the provision of a casing 47 surrounding the printing head and cam, this casing having a boss 48 mount ed on the shaft 31 and secured thereto by a driven pin 49, and the casing having also a flange 50 to provide a rear bearing for the casing, this flange surrounding a reduced portion of the clutch-member 35. The printing point of the apparatus is determined by a printing aperture 51, through which the engagement of the numeral wheels with the platen roll 41 takes place. The numeral wheels are therefore inaccessible while they are in non-printing position, and when they are in printing position, they are locked. The general theory of this apparatus is that the numbers set up on the numeral wheels are advanced by one with each revolution.
It is obvious that the invention might be embodied in other forms than those shown and described, without departing fro-m the important particulars of the improvement, which reside in the provision of means for guarding the numeral wheels of a numbering machine against tampering or interfen ence when the latter are in their accessible printing position, and furthermore in the provision of means for inclosing and shielding the numeral wheels when in their nonprinting position.
Inasmuch as many changes could be made in the above construction, and many appar' ently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
