RECORDING SCALE-BEAM.

SPECIFICATION forming part of Letters Patent No. 778,263, dated December 27, 1904. Application tiled March 9, 1904. Serial N0. 197,312.

T all whom, it may concern:

Be it known that I, ANDERS NILsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Recording Scale-Beams; and I do hereby declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in recording devices for scales, the object being to provide simple and eflicient recording means adapted to record tare and gross and net weights; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a side elevation of a scale-beam provided with recording devices constructed in accordance with my invention. Figs. 2, 3, and 4 are transverse sections of same on the lines 2 2, 3 3, and 4 4, respectively. Fig. is a plan of a card used in connection with the scale-beam to receive records of weight.

My said invention consists in providing a scale-beam consisting of a bar 1, pivotally mounted on the hangers 3 of the frame and connected with the platform, by means of the rods 2, in the usual manner. The said bar 1 is provided between its ends with a longitudinal slot 4, the parts 5 and 6 above and below said slot 4 forming guides for the balance - weight members 7, 8, and 9, respectively, and being provided with weight-indicatinggraduations 10, 11, and 12, said graduations 11 and 12 being located on the lower guide, which is provided with a stop 13, the forward edge of which registers with the Zero-mark of said graduations 12. lThe inner end of said slot 4 registers with the zero-mark of the graduations and 11 and is in vertical alinement with a shoulder 14 on said bar. Secured to the guide 5 is a bar 15, provided with notches 16, each having a vertical wall registering with the graduations 10.

The balance-weightmember 7 comprises an elongated inverted-U-shaped part 17, having one short flange resting upon the upper edge of the part 5 of said scale-beam and receiving the notched edge portion of the bar 15, the other fiange projecting below the lower edge of said part 5 and carrying a platform 18, which projects through said slot 4. Said member 7 is held against removal by means of a plate 19, mounted thereon and overhanging the front face of said part 5, said plate 19 being provided at its inner end with a recess to form an indicating-finger 20 thereon. In said inverted-U-shaped portion of said member 7 a lever 21 is pivotally mounted between its ends, one end of said lever projecting through a slot in the upper wall of said mmber and the other end thereof being adapted to enter the notches 16 in the bar 15, said end being normally held at the lower limit of its movement by means of a fiat spring 22.

The balance- weight members 8 and 9 are constructed similarly to the member 7 and carry platforms 23 and 24, respectively, and indicating-fingers 25 and 26, but are devoid of levers 21.

Each of said platforms 18, 23, and 24 is provided with a plurality of parallel longitudinal grooves 27 in the upper faces of their free end portions, each of said grooves being located a predetermined distance from the forward face of said bar l, and the parts 5 and 6 of the latter are provided with outwardlyprojecting' arms 28, 29, 30, 31, 32, 33, 34, 35, and 36, said arms being of various lengths and being provided in their free ends with vertical openings for the passage of the shanks 37 of button 38, having pointed ends adapted to puncture scale-tickets 39, inserted over said platforms of said balance-weight members. Springs are interposed between the heads of said buttons 38 and the upper faces of said arms to normally hold said buttons at the upper limits of their movement. Said arms and the grooves in said platforms are relatively so arranged that each of the points of said pins of the arms 28, 29, 30, and 31 are in vertical alinement with one of the longitudinal grooves in the platform 18, those of the arms 32 and 33 in alinement with the grooves of the platform 23, and those of the arms 34, 35, and 36 in alinement with the grooves of the platform 24. The number of grooves and pins IOO may obviously be increased or diminished, as desired, without departing from the spirit of my invention.

In connection with the devices hereinbefore described l employ a scale-ticket 39, carrying three sets of graduations 41, 42, and 43, said scale 41 comprising four columns of figures reading from 500 to 8,000 in multiples of live hundred, the graduations 42 comprising three columns reading from 0 to 500 in multiples of twenty-live, and the graduations 43 comprising two columns reading from 0 to 1,500 in multiples of fifty. It will be noted that each of said graduations 41, 42, and 43 coincides in its divisions with the graduations 10, 11, and 12, and the size of such ticket and length of each column coincide exactly with the distance between each two pins of any set which are designed to puncture on such column, as will be hereinafter more fully explained.

1n operation my device is as follows: Assuming that a wagon to be loaded is to be weighed before and after loading to ascertain net weight of the load, the ticket 39 is inserted over the platform 23 of said balanceweight member 8 and against stops 44 thereon after the said weight has been moved to the balance-point. This brings the columns of the graduations 43 of' said ticket over the grooves in said platform, the length of said columns coinciding exactly with the distance between the pins 32 and 33, so that both said pins cannot record at the same time, the wagon having been placed upon'the scaleplatform and said member 8 moved toward the free end of said bar until the latter is balanced, whereupon the ticket 39 is inserted and the pin then in vertical alinement with .the ticket is depressed to puncture the latter, thereby recording the exact weight of the wagon or tare. When the loaded wagon is returned upon the scale-platform, the said member 8 may be returned to the point coinciding with the record on the ticket or may be left at the inner limit of its movement. ln the event that the former course is adopted the ticket 39 is lirst again inserted over the platform 23 and the member 8 then moved until the record on the ticket is in exact vertical alinement with the pin with which such record was made. The ticket is then removed and the member 8 secured in position by means of the set-screw 47 thereon. The balance-weight member 7 is then moved outwardly until it is determined between which two marks of the scale 10 the weight lies, and, assuming that such weight is live thousand seven hundred and twenty-live pounds, the member 7 is moved back until the point of the lever 21 rests in the notch 16 in vertical alinement with the 5,5007 mark. The ticket 39 is then inserted and the weight is then .recorded on the ticket by depressing the pin rlhe ball 30, and the ticket is then removed.

ance-weight member 9 is then moved outwardly until the bar 1 or scale-beam proper is balanced, which in this instance would occur when the indicating-finger registers two hundred and twenty-live pounds. The ticket is then inserted over the platform 24 and against the stops 46 thereon, and the linger 35 is then depressed, and thus records this weight on the ticket. By adding the last record to the second the net weight of the load is given. lf the member 8 is not moved outwardl y to take up tare when the loaded wagon is placed upon the platform, then assuming the weight of such wagon to be one thousand pounds, the second record would be six thousand live hundred pounds instead of live thousand live hundred, and the total six thousand seven hundred and twenty-live pounds. By deducting the tare the net result would be the same.

It will be obvious that my invention may be applied to scales of any desired capacity and the specific arrangement herein illustrated and described modified to suit the purpose for which the scale is intended.
