United States Patent O Wire Cloth Division, Hanover, Pa., a corporation of Delaware Filed Oct. 24, 1965, Ser. No. 504,657 4 Claims. (Cl. 235-58) The present invention relates to apparatus for printing on a moving surface.
Thus, various types of sheet material can conveniently have indicia printed thereon while the sheet material is moving, and of course the distribution of the printed material on the sheet must be carefully correlated with the movement of the moving surface itself.
Various types of sheet material goods are supplied in roll or SpOOl form, so that one can conveniently cut from 'a roll or other supply source a desired length of the material. For example, sheets of screening, fabric, metal, and other forms of sheet material are generally required to be cut into predetermined lengths, and this latter objective is met at the present time simply by measuring a required length of the sheet and cutting it from the source. However, this conventional, age-old method is cumbersome as well as inaccurate and time consuming.
It is accordingly a primary object of the present in vention to enable sheet material of the above general type to be placed in a condition which will render the sheet material far more convenient to cut to a selected length.
In particular, the objects of the invention include the provision of an apparatus which will print directly on a moving surface of the sheet material numerical indicia which will enable an attendant thereafter to cut a desired length of the sheet material from the source thereof.
More particularly, it is an object of the present invention to provide an apparatus which, will automatically print on the moving surface of a moving sheet, such as a sheet of screening or the like, numerals which are in-. dicative of the length of the sheet, these numerals automatically being graduated as they are printed on the sheet so as to provide between successive numerals a distance equal to the length of the sheet as indicated by the numerals imprinted thereon. Therefore, it will be possible with such printing directly on the sheet for the attendant to cut the sheet into suitable lengths simply using for measuring purposes the indicia which is printed directly on the sheet with the structure of the present invention. "ltis also an object of the present invention to provide a structure, therefore, which will automatically totalize the length of the sheet or the like as it moves past a given point and will automatically print the length of the sheet at various increments thereof in accordance with the movement of the sheet.
The objects of the present invention also include the provision of an exceedingly simple and compact totalizing mechanism which is capable of printing graduations over a' range which would normally require with conventional totalizers far more totalizing structure than-that required by the present invention.
Furthermore, it is an object of the invention to provide a structure of the above type with a means which will enable the totalizing structure to be efficiently mounted on moving parts in a manner which will automatically actuate the totalizer so as to provide an accurate indication 3,327,941 Patented June 27,1967
of the length of the moving surface which moves past a given point.
Primarily with the structure of the invention there is a support means and a rotary housing carried by the support means for rotation about an axis which extends perpendicularly to the direction of movement of the moving surface. The rotary housing carries part of a totalizing means the other part of which is carried by the support means, and this totalizing means responds automatically to the rotation of the rotary housing for totalizing the length of the moving surface which moves past a'given point. Printing type is actuated by the totalizing means for printing indicia indicating this length directly on the moving surface simultaneously with the movement thereof.
The invention is illustrated by way of example in the accompanying drawings which form part of the application and in which:
FIG. 1 is a partly sectional front elevation of one possible embodiment of an apparatus according to the present invention;
FIG. 2 is a sectional side view of the structure of FIG. 1 taken along line 2--2 of FIG. 1 in the direction of the arrows; i
FIG. 3 is .a longitudinal fragmentary section of the totalizing structure, taken along line 3-3 of FIG. 2 in the direction of the arrows; and
FIG. 4 is an exploded perspective illustration of the components of that part of the totalizing means which is carried by a rotary housing of the invention.
Referring now to the drawings, the structure illustrated therein includes a support means 10 in the form of a suitable base member 12 having an upstanding wall 14, and this. structure is stationary and rigidfThe upstanding wall 14 has a suitable bearing which supports for rotary movement ashaft 16 which is continuously rotated in a well known manner referred to below. This rotary shaft 16 fixedly carries a rotary housing 18 of the invention. The rotary housing 18 has an axially bored hub 20 through which the shaft 16 extends and to which the shaft is fixed. For example the shaft 16 may have, as shown in FIG. 1, fiat surface portions engaged by suitable 'set screws which extend through threaded bores of the hub 20 for fixing the housing 18 to the shaft 16. The sheet material," such as screening,'forexample, is adapted to move from right to left, as viewed in FIG. 1, beneath the rotary housing 18. Part of this sheet'material 22 is indicated in phantom lines in FIG. 2.
The sheet material 22 is continuously advanced in a known way with a conventional structure which does not form part of the invention and is therefore not illustrated. Thus'the sheet material can be nipped between rollers which in a well known manner will provide a predetermined rate of movement of the sheet material. The upper surface of the sheet material is supported either on a suitable roller or on a suitable support member along which the sheet material slides so that the upper surface of the sheet material will be situated in a given plane which is the plane of the upper surface of the sheet material 22 as illustrated in FIG. 2.
A totalizing means of the invention is carried in part by the rotary housing 18 for rotation therewith and in part by the support means 10.
Considering first the part ofthe totalizing means which is carried by the rotary housing 18, it will be seen that this housing has a pair of relatively [robust portions 24,
and the housing is formed between the portions 24 with a space which receives various components of the totalizing means. The housing 18 fixedly carries a shaft 26 which extends across the space between the relatively heavy portions 24 of the housing 18, and this shaft 26, it willbe noted, is perpendicular to the shaft 16 while being fixed to the housing 18 for rotation therewith. Starting from the left in FIG. 1, it will be seen that there is situated in the space between the portions 24 of the housing 18, on the shaft 26, a washer 28, a units wheel 30, a tens wheel 32, a tens ratchet 34, a units ratchet 36, an actuating lever 38, and a washer 40 between the lever 38 and the right portion 24 of the housing 18, as viewed in FIG. 1.
As may be seen particularly from FIG. 4, the tens ratchet 34 is fixed directly to the right face of the tens wheel 32. The units ratchet 36, on the other hand, is fixed to one end of a tubular sleeve. 42 which extends slidably through the ratchet 34 and the wheel 32 while extending into and being fixed to the units wheel 30. Therefore, the sleeve 42 is situated between the shaft 26 and the tens wheel 32 and its ratchet 34, these latter elements being freely turnable on the sleeve 42.
The face of the rotary housing 18 which is visible in FIG. 1 fixedly carries an L-shaped bracket 44 which serves to carry a pawl pin 46 on which a pair of holding pawls 48 are mounted in respective alignment with the ratchets 34 and 36. Springs 50 are respectively connected to the holding pawls 48 and a pin 52 is also fixedly carried by the bracket 44, so that these springs urge the tips of the pawls 48 respectively into engagement with the toothed peripheries of the ratchets 34 and 36. Thus, while these ratchets can turn in a counterclockwise direction, as viewed in FIG. 2, the holding pawls 48 will prevent them from turning in a clockwise direction, as viewed in FIG. 2.
In addition, the right portion 24 of the housing 18, as viewed in FIG. 1, fixedly carries a supporting bar 54 (FIG. 2) to the bottom face of which is fixed an elongated leaf spring '58 which has, as shown most clearly in FIG. 4, a pair of free springytongues 60 respectively in alignment with and pressing frictionally against the ratchets 34 and 36. Therefore any possible play in the ratchets is eliminated by the friction spring 58 while turning of the ratchets in only one direction is assured by the holding pawls 48-. Because these pawls respectively cooperate with the ratchets independently of each other, it is possible for each ratchet to turn independently of the other.
The lever 38 of the totalizing means fixedly carries at one end a pin 62 connected to one end of a tension spring 64 whose oppositev end is fixed to the shank of the set screw 66 which also serves to fix the housing 18 on the shaft 16, as indicated in FIG. 1, so that the front end of the lever 38 is always urged upwardly by the spring 64. Situated beneath the actuated lever 38 is -a stop pin 68 fixedly carried by the right portion 24 of the housing 18, and thus the extent to which the lever 38 can be turned by the spring 64 is limited by engagement of the stop pin 68 with the lower surface of the lever 38.
This lever 38 fixedly carries at its rear, actuating end, a pawl pin 70 which servesto pivotally carry a stepping pawl 72 which is situated directly beside the lever 38 and carried by the latter. The width of the stepping pawl 72 is equal to the total width of both ratchets 34 and 36, and the stepping pawl 72 extends across both of these ratchets so that the ratchets are actuated in common, in a manner described below, by the one stepping pawl 72 which is pivotally carried by the lever 38. A spring 74 is coiled on, a pin 76 fixedly carried by the lever 38, and one end of the spring 74 presses against the upper surface of the lever 38, as indicated in FIG. 2, while the other end of the spring 74- presses against the pawl 72 for urging the latter toward the ratchet. In this way the spring 74 maintains the tip of 4 the pawl 72 constantly in engagement with the ratchets 34 and 36. e
As was indicated above part of the totalizing means is fixedly carried by the support means 10. This latter part of the totalizing means is in the form of a cam 7-8 fixed as by the screws a to the upstanding wall 14 of the support means, and this cam 78 has a curved camming surface 80 the curvature of which is most clearly apparent from FIG. 1. This curved camming surface is situated in the path of movement of the rear actuating end of the lever 38 which turns with the housing 18 in a clockwise direction, as viewed in FIG. 1. It is apparent that during each revolution of the housing 18 the rear end of the lever 38, which is the right end thereof as viewed in FIG. 2, will necessarily engage and slide along the camming surface 80 of the totalizing means, so that in this way the lever 38 will be turned in opposition to the spring 64 to a position shown in dot-dash lines in FIG. 2 with respect to its stationary position engaging the stop pin 68, and in this way the stepping pawl 72 is actuated to advance the ratchet teeth through a distance of one tooth with respect to the holding pawls 84. As a result at each revolution of the housing 18 at least one of the stepping pawls will be advanced by an increment of one tooth with this totalizing means of the invention.
In accordance with a further feature of the invention, the units wheel 30 carries a plurality of series of digits ranging between 0 and 8, so that more than one series from O to 8 is distributed along the periphery of units wheel '30. In the illustrated example there are two series of digits ranging between 0 and 8 and uniformly distributed along the periphery of the units wheel 30. Furthermore, in accordance with a further feature of the invention, the digits carried by the units wheel do not include all digits in the series. In the example illustrated only even numbers are included, so that in the units place of the totalized values given by the totalizing means of the invention there will always be an even number. The tens wheels on the other hand, carries a single series of digits ranging between 0 and 10 and all of the digits in this series are included at and uniformly distributed along the periphery of the tens wheel '32. With this arrangement .a tens digit carried by the wheel 32 will always be situated beside an even units digit carried by the units wheel '30.
As is apparent particularly from FIG. 2, the teeth of the units ratchet 36 are shallower than those of the tens ratchet 32, so that the. stepping pawl 72 will forthe most part advance only the units ratchet 36, and thus through the sleeve 42 the units wheel 30 will be advanced through an angular increment, corresponding to the angular distance of one tooth of the ratchet 36 at each. revolution of the housing 18.
However, two of the teeth of the units ratchet '36 are deeper than the others, and these are the pair of diametrically opposed teeth 82 which are respectively aligned with the 0 digits carried by the units wheel 30. As a result whenever the stepping pawl 72 reaches a tooth 82 it will advance the tens wheel 32 by one increment simultaneously with the units wheel 30, and in this way at each one half revolution of the units wheel 30 the tens wheel 32 will be turned by one increment. Thus with this exceedingly compact structure requiring no more than is required by conventional units and tens wheels it is possible to greatly reduce the wear of the parts. With the structure of the invention it is only necessary for the units wheel to turn through a half revolution in order to bring about results conventionally requiring a full revolution.
Thus, the extent of rotation of the housing 18 is such that, for example, every five revolutions of the housing corresponds to a length of 10 feet of 'the sheet material, and the totalizing means will indicate, for example, a
length of feet during five revolutions when the units Wheel will have been stepped through five increments while the tens wheel will have been stepped through one increment. The remaining half of the revolution of the units wheel will be completed during the next five revolutions corresponding, for example to the next ten feet. In this way the totalizing means is capable of totalizing from 0 up to 99 feet of sheet material before starting at() again. The digits 84 carried by the totalizing wheels 30 and 32 are in the form of printing type made, for example, of rubber and fixedly mounted on steel strips which in turn are fixed to the periphery of the wheels 30' and 32. This printing type is capable of receiving a coat of ink from a suitable ink supply at each revolution of the housing 18 so that when the totalizing means reaches its lowest position shown in FIG. 1 it is capable or" printing a numerical indication on the surface of the moving material 22 while moving at the same speed as the material 22, and in this way even-numbered graduations will be automatically applied to the moving sheet material indicating from one graduation to the next a distance of two feet, for example.
Additional subject matter may be printed with the structure of the invention. Thus, the housing 18 can carry additional printing type 86 carried by a suitable support which is fastened to the exterior periphery of the housing 18. In alignment with the additional type 86 are a pair of material-engaging elements 88 fixed to the housing 18 for rotary movement therewith and capable of engaging the sheet material so as to hold the sheet material in a condition rendering it more suitable for receiving an impression from the type 86.
This type 86 can be relatively localized and can have any desired configuration such as that of a suitable trademark, for example. In addition, however, it will be noted that the type 8 6 is situated at a part of the housing 18 which is diametrically opposed to the totalizing wheels 30 and 32. As a result, the mark which is made by the type 86 will be situated on the moving surface midway between the graduations imprinted thereon from the type 84 carried by the wheels 30 and 32, so that the mark provided by the type 86 can be usedto guide the cutting of the sheet material at locationssituated midway between a pair of graduations. It will therefore be seen that even though the odd-numbered graduations are lacking from those which are applied to the sheet material, nevertheless the type 86 will make a mark on the sheet material at those locations where the odd-numbered graduations would have applied their mark had they been provided, and thus the even numbered graduations together with the marks made by the type 86 situated midway therebetween enable the same results to be achieved as would have been provided with a complete set of digits at the totalizer. Of course, such a complete set of digits would have required the shaft 16 together with the housing 18 to rotate at twice the speed actually required with the structure of the invention, and in addition the totalizing wheel 30 would have required turning at twice the speed through twice the distance that it turns through with the structure of the invention. Therefore, the combination of the totalizing means together with the mark 86 greatly reduces the wear and tear on the parts, and in addition promotes an operation of the structure which is far quieter than would otherwise be possible.
