Referring to the drawings in detail, the embodiment of the invention is shownv incorporated in a scale of a well known type fully described in United States Patent No. 1,543,768 and in our description we will describe it only in so far as is necessary to properly disclose our invention. The scale consists of a base I, which for easy transportation from place to place, is mounted upon wheels 2. Load supporting levers (not shown) are suitablysupported within the base and these levers support a load receiving platform I. The load supporting lever system, in a manner which is well known. is connected by means of a rod 4 to an intermediatelever I to which, parallel to its longitudinal axis, a plurality of index beams I and I are secured. This lever 5 is fuicrumed upon knife edge pivots 5' within a column-like housing 8 mounted upon the rear of the base i. The beams 8 and I, however, are so arranged that they are in front of the column in an easily accessible position.

Theendsofthearmsofthiebracketil are provided with colinear pivots i1 and II" from which receptacles ll and II are suspended. one receptacle from one pivot and the other receptacle from the other pivot. The receptacle II is adapted to hang in a. water-filled tank II which rests on the shelf-like bracket II fastened to the column 8. It will be observed that the load counterbalancing pendulum mechanism It is set at approximately three-fourths of its total travel when the indicator 2!, which is connected to the pendulum and indicates their movement, is at the sero position on the chart 23 which is stationed .in back of the indicator and fastened to the housing ll.-

permits movement the indicator in clockwise and anti-clockwise directions. The anti-clockwise movement is about three-fourths the distance aroimd the dial and it is used in connection with the beam equipment in weighingooncrete mixture ingredients. Its travel in the clockwise direction is for straight weighing up to about one-fourth of the automatic weighing capacity of the scale andfor determining specific gravity, moisture-content, and mak-- ing sieve analysis of aggregates. I

The scale herein described may be used for straight weighing up to one-fourth'of its total capacity; for example, when the scale has a chart capacity of 1000 pounds, that is,. the capacity which can be counterbalanced by the automatic load ofi'setting pendulmns, loads up to approximately 250 pounds can be weighed. when the load is placed on the platform I, it will depress the supporting levers within the base i and a force, proportionate to the ratio of the levers, is transmitted through the rod I to the lever I. where it is diminished by the ratio of this lever and transmitted by the rod I and the lever II to the pendulum mechanism II. These pendulums will swing outwardly and upwardly from their initial position an angular distance proportional to the load and the indicator, which'is it crystailintion.

" sasss' usedforthisdeterminationissurface drysand, that is. sand which has been dried at a moderate heat, for instance, exposed to the summer sun. This moderate heat evaporates the water clinging t th sand particles. It should not, however, be of such intensity so as to drive of! the water of It is to be understood that the receptacles II and ll are exactly similar in size, shape and wehht. When the proper amount of material has been placed in the receptacle l8, the two receptacles are reversed in position, thatv is, the receptacle It with the sand contained therein, is carefully plunged into the water in the tank 2.. As the specific gravity is the ratio of the mass of a body to the mass of an equal volume of water, the force exerted by the submerged sand on the scale counterbalancing mechanism is less and the indicator will move in an anti-clockwise direction and indicate on the table 25 marked "specific gravity" (Figure X11), the specific gravity of the sample of sand which in this example, let us assume, is 2.64. When the receptacles it and I! are reversed, the receptacle II which previously was submerged in the water in the tank 20, before hanging it in the position occupied by the receptacle it, must be wiped dry. when the receptacle II with the sand contained therein is submerged, care must be taken in lowering it into the water to prevent undue agitation, as the surging thereof would have the effect of preventing the indicator 22 from coming to ,rest

- rapidly. Care in this operation also prevents sand from being washed out of the receptacle. Furthermore, care must be taken to see that sufllcient water is in the tank so that it completely covers the sample receptacle.

In determining the moisture content of the sand after the specific gravity has been established, the operator removes the receptacle containing the sand in the previous example, carefully empties, and washes it and again immerses the empty receptacle in the water. when both receptacles I8 and is are empty and the indica-' tor points to the zero on the chart, regular runv sand, that is, the sand as it comes from the builders supply yard is poured into the front receptacle it until the indicator 22 points to the flgure 2.64 on the table 24 (Figure XIII). It will be observed that the specific gravity of the sample of sand in the previous example was determined as being 2.64. The next steps in the determination of the moisture are to remove the empty submerged receptacle and to carefully dry it and then again exchange the position of the two receptacles, that is, the empty receptacle is now suspended from the pivot i'l' carried by the front arm of the bracket l1 and the receptacle containing the regular run sand is carefully lowered into the tank 20 and suspended from .the co-linear pivot I'I" carried by the back-arm of the bracket IT. The percentage of moisture will now be automatically shown on the table 28 marked "percentage of moisture" (Figure XII); In the example, this percentage will be assumed to be 8 per cent of the weight of the sand per se.

Having thus determined the percentage of surface moisture in sand, the next step in the operation of producing a theoretically correct concrete mixture is to weigh out the required amount of sand for the batch and to compensate for the sill face moisture contained therein. The receptacle containing the sand is again removed from its hanger, carefully emptied, washed and again immersed. Both receptacles are now empty. The beams I and I which are secured to the intermediate lever i are provided with series of

indicia

21 and 28, and 2| which co-operate with poises II, I2, 22 and Il. The scale in which we have shown our invention embodied is of the so-called portable type and has a comparatively small platform 2 and when used for the purpose herein described, it is necessary that an auxiliary container be placed thereon to hold the concrete mix constituents. This container may be a barrel or a box having the proper size, and its weight is counterbalanced or tared out" by moving the poise 3! towards the right, from its initial position until the indicator 22 again points to the zero indicium of the chart 2!. The poise 22 is now moved along the beam 8 over the series of indicia 28 to the indicium which represents the amount of surface dry sand desired. The poise 32 has a downwardly projecting arm 25 which is equipped with a pivot 28 at its lower end from which a stirrup 21 and a weight hanger II are suspended. The length of the arm 25 is such that the knife edge of the pivot 20, fixed in its lower end, is in the plane of the pivots 5' in the lever 5. As the pivot 39, from which the stirrup II and weight hanger II are suspended from the poise 34, is directly in this plane, a special arm is not necessary and the pivot 29 is fixed directly into the body of the poise 34. When in their zero position, the pivots It and 28 are colinear with the fulcrum pivot of the intermediate lever 5. The poise I2 is placed in a position to counterbalance, let us say in this example,

259 pounds of sand; the indicator 22 has moved v 8% per cent and the indicator 22 will point to the 281 pounds indicium on the chart 23 which is the total weight of sand and adhering moisture which must be weighed out to obtain exactly 259 pounds of surface dry sand. Sufllcient regular run sand is now placed in the container standing on the platform of the scale to bring the indicator 22, which is now moving in a clockwise direction, to the zero indicium. In the proper compounding of concrete mixes, it is customary that more than one kind of sand or other aggregates be used. Let us assume that the next step is to add 375 pounds of a coarser aggregate. Without removing the sand from the container or disturbing the setting'of the poise 32, the poise 34 is moved on the beam 1 to the 3'75 pounds indicium and the proper percentage weight 42 is placed on the hanger H to compensate for the surface moisture which, we will assume, amounts to four per cent of the coarser aggregate per se, or 15 pounds.

The indicator 22 now points to the 390 pounds indicium and is returned to zero when the proper amount of aggregate is added to the previously weighed out sand in the container.

It is not necessary to compensate for moisture in cement and we may weigh out the cement without removing the sand and coarser aggregate from the container or disturbing the setting of the poises I2 and 3|, by moving the poise 22 on the beam 1, to the proper weight indicium which in this example is 94 pounds in the series 2!, and

field, have established the fundamental law that mixing water used per and this quantity is governed by the conditions of the structure and the different degrees of exposure to which it will be subjected; In the example herein described, we will assume that the correct amount of water for the mix is 58 pounds. with the device in a balanced condition. that is, the indicator is in registry with the zero'indicium and the load still on the platform, when the moisture percentage weights 4! are removed from the hangers ll and II, the automatic load counterbalancing pendulums are again overbalanced and move outwardly and upwardly proportionally to the amount of surface moisture compensated for by the moisture percentage weights and-the indicator 22 revolves in a clockwise direction and indicates the amount of water clingmg to the aggregates. In the example, the 8% per cent of-surface moisture in the sand is 22 pounds and 4 per cent adhering to the coarser aggregate amounts to 15 pounds. The indicator thus points to 3'1 pounds and the operator adds only suflicient water to cause the indicator 22 to point to the 56 pounds indicium on the chart 23.

In the introductory part of this description,

the statement was made that one of the objects of the invention is the provision of means whereby permanent records maybe made, both automatically and manipulatlvely, of the composition of batches of concrete, the date, and/or the location where they are finally poured. To fulfill this object, the scale is equipped with the automatic strip recorder I and the thereto coupled driving mechanism II which is operated by the movement" of the counterbalancing pendulum mechanism II. This driving mechanism comprises a bracket H which is securely fastened in a horizontal position to a vertically extending track frame 45, on which the pendulum ll and H are fulcrumed by means of iiexlble metallic This bracket is provided, on its upper faces, with V-grooved anti-friction tracks 48 on which a number of accurate bearing balls I! are resting. These balls in turn support similar V-grooved anti-friction tracks ill which are fastened to the lower side of a horizontally disposed carriage member ii. A rack 52 is pivotally secured'to an upstanding fulcrum boss 51 on the carriage: pinion 54 which is secured to a pinion shaft 55 indicator 22 is fastened. This shaft also carries the driving pinion 58 which translates the reciprocatory motion of the rack 51 into rotation of the indicator 22. The rack 51 is in a known manner operatively connected to the load counterbalancing pendulum mechanism l3.

when a load is placed on the platform 3, the force resulting from its weight actuates the counterbalancing mechanism in the manner hereinbefore described and as the carriage 5| of the recorder driving mechanism is actuated thereby, every angular movement of the indicator is again translated into a reclprocatory movement of the carriage 5| which is connected by a very light connecting bar 58 to the stylograph arm of the The recorder mechanism per se is The teeth of this rack mesh with a wellknown andwewill hereinafter describeonly the improvements we have made therein. It is obvious that as the movement of the indicator is always in proportion to the load on the platform, the horizontal reciprocatary motion of the carriage I will also be inproportion and consequently, the length of the line traced by the stylograph of the recorder will be ameasure of the weight of the load causing the initial movement. In the example hereinbefore considered, the concrete batch consisted of 259 pounds of sand, 375 pounds of a coarser aggregate. 94 pounds of cement and 56 pounds of water. Figure XIX illustrates a portion of a recording strip showing the curves automatically made when the ingredients for the batch of concrete are weighed and determined. The longitudinally extending lines printed thereon, represent the weights in pounds of the different materials. The distances between the curved transversely extending lines represent time intervals. The recording device is adapted for adjustment, that is, it may be adjusted to feed the strip at different rates per hour, to suit the speed with which the batch ingredients can be loaded and mixed. The zero or datum line on this strip is not located in the center, as the automatic load counterbalancing mechanism, which controls the recording stylograph, is adapted to move through a larger angle when the indicator is travelling in the anticlockwise direction, than when it is travelling in the clockwise direction. when the device isin a balanced condition and the recording mechanism in operation, the stylograph will trace a line 59 which overlies the zero line of the recordin strip. When a poise, for example poise 32, is moved on the beam I to the 259 pounds indicium to counterbalance the weight of the desired sand; the stylograph will trace the line 50 until its length is proportional to 259 pounds. The addition of the 8% per cent moisture percentage weight will increase the length of the line until it is proportional to 281 pounds. As 8 /2 per cent of 259 pounds equal 22 pounds, the sand is now placed in the receptacle on the platform on the scale. The line ll represents the operation of loading the receptacle with the required 281 pounds of sand. The time interval for this operation is represented by the height of the curve, measured vertically from points 52 to 83. Similar graphs 64 and represent the amount of coarsegravel and the cementplaced in the receptacle on the platform. It will be noticed that whenever the required amount of each of the ingredients is placed on the platform, the stylograph returns to the zero line, as the device is then in a balanced condition. Any deviation from it would instantly show that the amount placed on the platform is inaccurate. When all the dry ingredients are on the platform, the percentage weights 0 are removed from the hangerg and the stylograph will move on the other side of the zero or datum line of the recording strip a distance proportional to the amount of the surface moisture clinging to the aggregates, and tracing the line I. The addition of the correct amount of water will trace the line 81 and the removal of the batch ingredients will return the stylograph to the zero line.

when the apparatus is started in the moming, the inspector or operator may mark the date and time at the beginning of the graph as at 88 and it is desirable that the ingredients be placed in the receptacle in a predetermined rotation and that the previously determined moisture percent- To later identify the location where each batchwas placed, the operator or inspector makes idenfrin notes on the raph as at Ii. To facilitate these manual notations, wehave provided a small platen II directly underneath thefrecording strip ll between the driving roller I4 and the, idler roller II: and have also provided a hinged cover 1| with a lock 11' so that unauthorized or fraudulent notations can be prevented (Figure x). V

To facilitate simultaneous indications and records of the operations at a point remote from the device, for example, in the omce of the supervising engineer or in case the device is used in connection with a central concrete mixing plant on top of the mixing tower, we have provided the device with a self-synchronous generator motor system which comprises a generator Ill mounted co-axially with the indicator shaft 55 and connected thereto by the clutch member If. The generator 80 is mounted on a bracket 82 which in turn is fastened to the frame I and there is also provided a remote indicator (Figure xv) which consists of a circular housing "in which a frame 84 is fastened-to brackets II and, I! which may be integral with the housing. A pair of ball bearings I! support an indicator shaft to inbefore The rotors: the generator of the self-synchronous motor generator system, being also directly connected to theindicator shaft II, is also turned, and, since the rotor of the motor 02 turns to the same extent, the shaft "will move through the same angle as the indicator II and indicate a similar indicia. The

ll, being also mounted on the shaft 88, causes the recorder drive carriage It to actuate the stylograph of the recorder ll similarly and a duplicate graph is traced On its recording strip.

It will be. seen from the foregoing that the emmechanism in the weighing device.

which an indicator 8! is fastened. The indicator ll co-operates with an indicia bearing chart .0 which is a counterpart of the chart 2!. This chart is mounted in back of the indicator I! in the housing IS. A bracket 8i, which is similar to the bracket 82, is fastened to the frame It and supports a motor I! co-axially with theindicator shaft GI and a coupling N is provided to operatively connect them. A recorder drive mechanism at, which is a counterpart of the recorder drive mechanism II, is driven by a. pinion II which is mounted on the indicator shaft ll. As the construction and operation of the recorder drive mechanism are similar to the recorder drive mechanism II, we havenot particularly shown it in the drawings and will not describe it at great length. The carriage 96 is connected by a light connection 81 to the stylograph mechanism of the recorder ll.

When a self-synchronous generator motor system is employed, the field coils SI of the generator are connected with the field coils Ill of the motor as shown in the wiring diagram (Figure XVIII). when the generator rotor is turned by the movement of the counterbalancing pendulum system II, the indicator rotor will turn in synchronism and will assume a similar position at the end of the movement. As the operation of the self-synchronous generator motor systems perse are well known, we will not describe them in greater detail. ,7

when, due to the action of a load on the platform 3, the pendulum counter-balancing system I! is unbalanced, the indicator shaft 55 rotates the pinion i4 fastened to it. drives the rack 52 which is fastened to the carriage II of the recorder drive mechanism connected to the recorder it and causes it to trace the graphs here- It is customary in scientific concrete batch mixing, to make a sieve analysis todetermine whether the aggregates have just the correct proportion of large medium and fine particles,

as it is essential that they are of such composition that all the voids between the larger fragments of rock are completely filled by the finer particles. The device, therefore, has also been so designed to enable the operator to make this analysis with great facility. Aggregate is poured into the receptacle it until its weight overbalances the counterbalancing pendulum mechanism i2 and thereby turns the indicator in the clockwise direction to the pounds indiclum on the chart 23. This quantity represents 100 per cent of the sample and will weigh slightly less than one pound. This sample is now placed in the upper sieve of a nest of standard sieves and shaken by hand or by means of a shaking apparatus built for this purpose. As the meshes of these sieves are graduated in size, and the one with largest openings is placed on top and the one with the smallest opening on the bottom, the different size particles are readily separated, and particles of uniform size will remain in each sieve. The contents of each sieve are then placed separately into the receptacle l8; and the indicia. indicated by the indicator 22 on the chart 23 represents the percentage of the total, of that particular size particle, in the sample. The engineer in charge of the structure may thus easily select aggregates having the proper proportion of the diifcrent particles. It has been found that greater economy can thus be realized in obtaining the desired strength of theconcrete.

-.At times it may be advisable to know the amount of water of crystallization or in other words, the percentage of water absorbed in the structure of the aggregates. This is determined in exactly the same manner as the amount of surface moisture hereinbefore described, with the exception that the sample is bone dry, that is, the sample was previously exposed to a temperature suihciently high to drive out all absorbed moisture. The percentage of this moisture will be indicated by the graduations below the zero indicium on the table 26 (Figure XII).
