To all whom it may concern:

' a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Mechanical Recording-Scales, of which the following is a specification, reference being had therein to the accompanying drawings,forming part of this specification, in which- Figure 1 is a view in front elevation of my improved registering-scale.

Figs. 13 and 14 are detail views showing a modified construction of wheel-turning mechanism.

Fig. 15 is a detail view illustrating a modification.

My invention relates to an improvement I in scales; and it consists of means whereby each operation of the scale is registered in conformity with the weighing operation by means of one or more type-wheels which print the weight for each operation upon a tape which progressively travels through the machine and is thus provided with a record of all of the operations for an stated period. The printing-wheel is direct y controlled by the poise through a connection adapted to bring the proper t position correspon in to the wei'g t indi cated by'the poise on t e beam.

The invention also provides means for application to scales of different capacity by combining the poise's of a double beam-scale. with a double wheel construction and also for automatically adjusting a supplemental printing-wheel by the removal of the weights.

Referring now to the drawings, 2 is the cap of a scale provided with the usual balancinge-figures into rinting' beam3 and poise 4, the beam being preferably provided with a clearance-opening for the passage and protection of the chain.- Mounted upon the cap 2 is an inclosing case 5, Within which is located the printing registering mechanism, the case being provided with a door or gate 6, adapted to be locked to prevent unauthorized intrusion, it being desired to accumulate the recorded weights during any stated period, as a day, and to remove a portion of the'strip containing them at the termination of such period for examination or filing.

Rotatabl mounted on a spindle or shaft 7, journale in bearings in a suitable frame 8 Within the case, is a Wheel 9,provided with a series of printing type-figures 10, arranged a partially or wholly around its periphery, the

wheel also being provided wi a groove 11 for actuating chain or cord 12,whichis secured to the wheel at a point sufliciently far around its circumference to insure suflicient rotation for the greatest range of movement of the poise 4. The chain 12 passes from wheel 9 downwardly around a guiding-sheave wheel 13, mounted in a suitable openin in the beam, and is connected to the poise 4, as

shown, so that as the poise is moved out-' wardl -to the indicating-point on the beam it wil carry the chain with it, andthus anchor that end of the chain, so that when the wheel is' rotated, as hereinafter described, it will act to limit its movement at the proper point for correct printing.

The mechanism is acuated by a key-lever- 14, pivoted at 15,provided with a de ressingterminal 16, extending outwardly t rou h a slot in the end of the case 5 and normally eld retracted inposition for operation by a spring.

17. A wheel-actuating arm 18 is pivotally 23 is a roll of paper tape rotatably mount- I ed on bearin s 24, journaled in suitable supporting-brac ets 25, the tape being arranged 1n alinement with the type-wheel and adapted to be drawn successively from the roll asit is used.

The arm 14 is provided with a laterallyarranged inwardly extending t mpan 26, preferably rounded at its upper si e to insure good contact and to prevent contact with the adjacent non-registering type and provided with slots 27 27, through which the tape is laced, as clearly shown in Fig. 4, so as to present a limited section only of the tape a ainst the type. The lever 14 is also provide with a locking pin or abutment 28, adapted to engage notches or grooves 29 around the edge of the type-wheel and to fixedly adjust it to the exact position desired at the moment when the printing operation takesplace. The

type are inked b r a roller 30, mounted in a frame 31, pivota ly mounted on bearing-pin 15 or elsewhere and normally held in contact with the type by spring 32.

The tape passes from the printing-tympan around a guiding pin or roller 33, mounted in frame 31 or elsewhere, in a suitable position to lead the tape downwardly away from the type and then upwardly between a springpressed feeding-roller 34 and a feeding-wheel 35, convenientlymade in the form of a ratchetwheel. The feeding-wheel 35 is rotatably mounted on a bearing pin or shaft 36, journaled in a suitable bracket 37 while the roller 34 is rotatably mounted on a pin or shaft 38, carried by a housing 39, slidingly mounted upon supporting guiding extensions 40. The roller 34 and the intervening tape are held into operative engagement with feed-wheel 35 by springs 41, connecting shafts 36 and 38, or otherwise suitably applied, and the housing 39 is provided with a button 42, by which it and the roller 34 are raised to free the ta e when it is desired to draw it freely from t 1e machine for removal of a completed section or series of printed numbers.

Feeding movement is imparted to the tape at each operation of lever 14 b means of a spring-pressed pawl 43, pivote at 44 in an arm 45, secured to the hub or any suitable portion of the lever, as shown. The pawl passes downwardly on downward movement of the lever, engaging one of the ratchetteeth 46 of wheel 35 on upward movement due to spring 17 after the printing operation, thus shifting wheel 35 one space and correspondingly moving the tape forward sufficiently far for the next operation.

For the purpose of assisting in reversing the wheel 9 at the last portion of its reverse travel, also bringing it to a constant initial position, and to insureinking of all of the type and relieving the chain 12 of strain, a counterweight 47 is suitably secured upon the wheel, although ordinarily the friction-arm 18 will impart reverse movement to it when the lever is retracted. A dash-pot 48 is connected at 49 to lever 14, adapted to engage a plunger-rod 50, pivoted at 51, which acts to revent a too sudden action of lever 14 and its connected parts.

It is desirable to give a signal when the. lever 14 has been depressed to its full limit, and thus insure. a complete operation, and for this purpose I have provideda bell 52, which is sounded by a tapper 53, thrown into contact by the upper end of arm 18 at about the limit of its upward travel, thus indicating to the operator the completion of a full operation. It is obvious that the bell or other similar signal may be located at any suitable position in the apparatus and that it may .be sounded by any convenient mechanism ada ted to be actuated by the operative mec anism at the proper time, as stated.

The operation will be readily understood from the foregoing description. In the operation of weighing, the poise is located upon the beam, which is preferably notched to prevent disturbance of the poise by the tension of the wheel on the chain. -The movement of the type-wheel is thus regulated, so that the printing-figures corresponding to the indicated weight will be arrested b the chain in properlocation for printing, an the operation is completed by depressing the lever and then releasing it, the tape thus being imprinted with the recorded weight. The successively-recorded weights will be imprinted in alinement with each other and may easily be added together to find the total weight for any selected period after the tape has been torn off and removed.

The machine just described is adapted only to a scale having the capacity indicated by the maximum capaeit graduated on the beamas, for instance, our hundred pounds. When it is desired to apply the invention to scales of larger capacity than can be graduated over the range of a single beam, I employ the modifications shown in Figs. 9, 10, 11, and 12. In the construction shown in Figs. 9 and 10 means are rovided whereby upon removal of the weig its 54 from their rack for use on the outer end of the beam movement proportionate to the width of the weight is imparted to a supplemental hundreds or thousands wheel 55 through a connected pinion-wheel, en aged by a rack bar 56, normally retracted y a s )ring 58 and normally held outwardly by t 1e weights or some of them when in position on the rack. As one or more weights are removed for use the rack-bar will be proportionally retracted, rotating the pinion and ty )e wheel to its proper position, said wheel t hen operating in conjunction with the units-wheel t). It will be understood that otherwise the same mechanism is employed performing the same functions, it being only necessary to provide a sufliciently wide tape with a corresponding change in the other elements, the lever 14 being provided with an additional arresting or adjusting pin 28 for the additional wheel. This mechanism operates as follows: During the operation of weighing and recording we will sup )ose the beam to be graduated over a range of one hundred pounds, each notch on the beam representing one pound, the. full ICS capacity of the scale being, say, six hundred pounds, the difference between one hundred and six hundred bein made up b the use of weights. In the we1 hin of a oad of, we will say, -four hundre an sixty pounds the first 0 eration will be to remove four hundred pound; in weights from the weightrack and to place them on the counterpoise on the end of the beam. This will effect to allow the bar 56, actuated b into the space whic was'previousl occupied by these weights, and consequent y turn by the rack-and-gear movement the type-wheel 54 to such a position as will make it print the figure 4 1n alinement with the number 60, which will be printed by type-wheel 9, controlled by the chain and brought to position by the oise and lever mechanism when thelever is epressed for the purpose of makin a record.

In the modification shown in Figs. 11 and 12 a double beam is used, the lower bar 59 of which is traveled by a sufficiently heavy poise to balance at its greatest movements over the full ca acity of the scale. I merely provide a supp emental type-wheel 55, provided with figures corres ending to the hundreds and thousands of earn 59, connected by a chain 12, said wheel operating in conjunction with units-wheel 9 through a duplicate set of mechanism, the same in all respects as that already described.

In Figs. 13 and 14 is shown a modified arrangement of the friction mechanism by which the type wheel or wheels are brought to the proper position for rinting on depression of the key-lever 14. In place of the rubber hub. 21, fixed to wheel 9 or its shaft, a pinion is engragedby a rack-bar 61, corresponding to iction-arm 18. The pinion 60 is loose on the wheel-shaft 62 and is provided with a spider or star wheel 63, the arms of which bear with considerable friction against a washer 64, of leather,rubber, or other frictional material, secured to the side of the typewheel.

In Fig. 15 I have shown a detail view illustrating a modified construction of connection between the poise-chain and the poise, employing a terminal wedge, adapted to be drawn forward by the chain between the 0ppositely-dis osed arms 65 65 of the oise and to expand t em a ainst the inner si es of the slotted beam. T 's construction is designed as a substitute for a notched beam and operates to clamp the poise in osition, its bmding hold inereasing, so that it will thus be held rigidly in position against disturbance by the printing operation.

The advantages of my invention will be readily appreciated from the foregoing description, and it will be found to perform itsfunctions in a satisfactory and efficient manner. The mechanism is com aratively simple, not liable to get out of or er, and the rethe spring 57, to move sults secured are hi hly desirable and render the accurac of weiiin weights in ependent of the operator and therefore not subject to mist'ak Chan es and variations may be made by the skilled mechanic in the various parts or details of construction; but all such are to be considered as within the scope of the following claims.
