TONNAGE-EQUATING MACHINE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed January 4, 190. Serial No. 294,662.

To all whom 'it may concern:

Be it known that JOHN M. DALY, 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 Tonnage-Faquating Machines; and I do hereby declare that the following' is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention has reference to a computing machine and relates particularly to a device for equating train tonnage or for measuring the resistance of railway-trains.

One of the objects which I have in view with the present device in the equation of train tonnage, is to give an average allowance of draw-bar pull per car, thereby allowing the same to each weight of car next to the engine or caboose.

The results to be obtained by the present device is in most respects similar to that obtained by machines upon which patents have already been granted to me and by others upon which applications for patent are now pending. The patents referred to are numbered 715,197 dated December' 2, 1902; 715,199 dated December 2, 1902 and dated December' 2, 1902. The applications for patent to which reference has been. made were filed on April 11th, 1904 and August 15th, 1905 and bear Serial Nos. 202,552; 202,553 and 274,342.

For a further and full description of the invention herein and the merits thereof, and also to acquire a knowledge of the details of construction of the means for eifecting the result, reference is had to the following description and drawings hereto attached.

`While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a tonnage equating device embodying my improvements; Fig. 2 also shows a top plan view of my device and with the top plate or covering removed to show the relative arrangement of the working parts in the casing forming a part of said device; Fig. 3 is a cross section through the device, to illustrat-e in side elevation the mechanism which controls the actuation of certain registering wheels, and known as the car numbering device; Fig. 4 is a cross section through the device to illustrate in side elevation certain trip mechanism and a gong, whereby in the operation of the device the gong is sounded to indicate that the car limit in making up a train of cars has been reached; Fig. is a cross section through the device, to illustrate in side elevation certain tonnage computing or registering wheels and coperating parts; and also the car registering or tallying wheels and cooperative parts; Fig. 6 is a longitudinal and sectional detail through a portion of the device; a driving shaft and tonnage computing or registering wheels in cross section on the said shaft; Fig. 7 is a longitudinal and sectional detail through a portion of the device; a shaft and car tallying or registering wheels in cross section thereon, and 8 is a cross section taken through a portion of the casing of the said device and showing a revoluble wheel, disk or plate; a superposed plate or disk and the manner of mounting both of said disks also a locking mechanism carried by the superposed disk adapted to normally engage a part of the casing.

In the drawings like numerals of reference indicate corresponding parts throughout the figures.

1 refers generally to a casing having the side and end walls 2 and 3, the bottom 4 and a top or covering which in this instance is shown having a detachable connection with the casing by means of the screws 6. The said top or covering 5 is further provided with an annular cut out portion 7 and from the edge of the said cut out portion 7 the top is beveled rearwardly as at S to the surface thereof. At 9 the covering is provided with a sight opening whereby an operator may readily see certain car tallying mechanism, to be described which is disposed in the casing beneath the opening 9 and at 10 is also shown a sight opening in the covering 5 whereby an operator may see certain tonnage computing or registering wheels disposed in the casing beneath the said opening. EX- tending up from the bottom 4, see Fig. S, is shown a standard or upright 11 having a reduced upper extension forming a shoulder 12 and the said standard is further provided with the interiorly threaded portion 13,

the reduced upper extension of the standard p 11 and to accomplish this the said disk is provided with the depending tubular Vportion 16 designed to be slipped over and encircle the standard 11 somewhat as seen in Fig. S and having its lower edge resting on' the olf set 12 of the standard 11. ln working position the disk 15 is disposed in the casing beneath the annular opening formed therein and the outer edge of the disk extends beyond the edge 7 forming the annular open way in the said casing. The disk 15 is further provided with the dependent flange 1T projecting downwardly from the outer edge thereof and is provided with a series of teeth 18 extending around the entire lower edge of the iange 17.

19 indicates a series of perforations in the disk 15 and are spaced, preferably equidistant to each other in a circumferential row around the disk.

2O denotes a superposed disk or annulus plate which is adapted to be rotatably held on the upper end of the standard 11 by means of the screw or plug 14 which passes through an opening in the said plate and has a screw connection with the standard, as described.

The disk 15 and the annulus plate 2O areV adapted to be held spaced apart, to permit of a free rotation of one or the other of said parts, for purposes which will be hereinafter apparent, and to separate'the two parts l have provided the washer or interposed disk 21 which encircles the upper end of the standard 11, somewhat as seen in Fig. 8.

The superposed annulus plate 2O has itsV outer peripheral edge located within the circle described by the series of perforations 19 arranged in the disk 15, and is spaced from the edge 7 of the covering 5 forming the wall of the cut out portion therein to provide the annular channel way 22 between the wall 7 and the peripheral edge of the annulus plate 20, beneath which and corresponding to the annular channel way is disposed a series of perforations 19 in the disk 15.

The disk 15 is adapted to have a free rotation in opposite directions, while the annulus plate is normally arranged stationary and locked in adjusted position, suitable locking means being provided which will now be described and the purposes of which hereinafter explained. On the annulus plate 20 at a suitable point is secured a block 23 which projects across the channel way 22 heretofore described and clearly seen in Fig. S; the said block is provided with an open tubular chamber 24 which communicates with a reduced longitudinal opening 25.

Operating in the longitudinal opening and chamber just described in the block 23 is a stem 26 on the rear end of which is carried a block or has formed thereon the head 27 provided with the depression or slot 28 projecting inwardly from the upper face thereof; and on the opposite end of the said stem and carried within the chamber 24 is a plug 29 between which and a shoulder formed by the wall of the chamber 24 and the longitudinal opening 25 is carried a coil spring 30 which encircles the said stem. The extreme outer end of the stemV 26 when in normal position is adapted to engage with one of a series of slots 31 arranged in the inner edge of a block 32, which may be attached to or form a part of the covering 5 of the said device. rlhis block is of suitable width and length and in contour forms the Y segment of a circle so that the edge thereof in Vwhich the series of perforations 31 are arranged is on the same radius as the edge or wall 7 which forms the annular cut out portion of the covering 5.

it will readily be seen from the above de scription, taken in connection with Figs 1 and 8, that if it is desired to adjust or par tially rotate the annulus plate 20 it is only necessary for the operator to insert a pointer or pencil of some suitable description into the perforation or depression in the head 2'? and drawing the same outwardly willY disengagc the end of the stem 26 from the perferation 3 1 with which it is then engaging in the block 32; upon the release of the pencil or pointer from the head 27 the tension of t-he spring 30 against the plug 29 will force the stem 26 outwardly, and it in Vturn will engage with the desired perforation in the block 32; or if upon the release of the stem 26 from the block 32 it is desired to place the annulus plate in a position for its disconnection from the casing or the standard 11 therein, the said plate will be rotated sufliciently to entirely disengage the stem from the said block when, upon the removing of the -screw or plug 14 the said annulus plate may be removed. It is adapted when rotating or partially rotating the disk or plate 15, in a manner to be described, to impart motion to a series of numbering wheels which are adapted to register train resistance computed by the actuation of the said disk in connection with an expanded and contracted scale; also to actuate certain car tallying mechanism for registering the number of movements of the said disk 15, which movements correspond to the number of cars which are placed in a train the resistance of which it is desired to obtain; furthermore and in the operation of the disk 15 it is intended at a pre-determined number of operations thereof or when the car tallying mechanism has moved to a certain point to signal by means cfa gong that a given number of cars have been placed in a train which indicates that the train limit has been reached.

Through the casing from one end thereof to the standard 11 is carried a shaft 33 which is journaled in a suitable bearing formed in the standard 11 and in the end wall of the casing, best seen in Figs. 2 and 6. Suitably secured on a shaft to rotate therewith is a pinion 3st which is in mesh with the teeth 18 of the depending flange of the disk 15, see Figs. 2 and 0 and carried on the said shaft between the end wall of the casing and the said pinion 3% is seen a series of registering wheels, forming respectively7 the unit, tenths, hundredths and thousandths wheels which together form the tonnage registering wheels of the device. `Each of the wheels is provided with a series of numerals from 0 to 9. The units wheel is indicated as 35; the tenths wheel as 36; the hundredths wheel as 37 and the thousandths wheel as 38. The first mentioned Wheel is adapted to be iixedly secured or attached to the sha-ft 33, see Figs. 2 and 6; while the remainder of the wheels, are all shown loosely carried on the said shaft.

The registering wheels 35, 3G, 37 and 38 are not unlike registering wheels which are in general use in machines of this class and it is hardly thought necessary7 to describe the detail construction thereof, other than a general description to show how one of such wheels is capable of transmitting motion to its adjacent wheel. rllhe units wheel 35 described vas being secured on the shaft 33 is provided with a single tooth projecting late ally therefrom, the same being substantially like that shown on the wheel 3? best seen in Fig. the Wheel 38 being broken away for the purpose of illustrating the same. lilith each movement of the shaft 33 the wheel 35 is correspondingly moved and with each complete rotation thereof the tooth 39 is adapted to engage with a tooth of a pinion i0 and move the said pinion the distance of one tooth. This pinion contains a series of teeth and each alternate tooth thereof is only half the width of the said pinion, for a purpose soon to become apparent. The wheels 3G, 37 and 38 which are loose on the shaft are in most respects similar. That is, each of the said wheels is provided with the toothed portions 36a, 37a, and 38a respectively, which extend completely around the periphery of the said wheels, and on the opposite sidesl of the wheels 30 and 3T only are provided single teeth 41 and Ll2, similar to the tooth 39 on the wheel 35 and each is adapted during a rotation thereof to engage with the tooth of a pinion Li3 and del. for the purpose of mving the said pinions the distance of one tooth during each revolution of the said wheels. For a better understanding of the operation of the registering wheels it is understood that through the movement of the disk l5 the shaft is actuated through the pinion and through such movement of the shaft the units wheel 35 is also rotated. Then the units wheel makes a complete rotation its tooth 39 engages with the pinion l0 and moves it the distance of one tooth; the toothed portion 3ba of the wheel 3G is continuously in mesh with the pinion 40 and when the latter is moved the distance of one tooth it will be seen that the wheel 30 is moved the distance of one tooth. The wheels 3T and 38 have their toothed portions 37a and 38a in mesh with the pinions 3 and elet, so that with each rotation of the wheel 30 its tooth 41 will move the pinion t3 the distance of a tooth and it in turn will move the wheel T the distance of one tooth; and when the last mentioned wheel has made one revolution its tooth l2 will engage with the pinion it and move it the distance of one tooth and it in turn will move the wheel 38 the distance of one tooth.

In connection with the perforated disk 15 l have provided a scale or chart and the same is indicated as a whole, as 45. This scale or chart is preferably placed on the inclined face 8 of the covering 5 and the characters which go to make up the said scale are arranged opposite a perforation 19 in the rotatable disk 15. The designating characters are preferably numerals and the said scale has both, a contracted and expanded portion. The contracted portion being that portion of the scale between 1 and 40 and the expanded portion of the scale is that part between the numeral 40 and 75 The arrangement of the numerals which go to make up the scale is from 1 to To i and is suthcient to illustrate the principle involved and the mode or system of reducing train tonnage to train resistance; although, the scale or chart might be continued to a greater length if it is so desired. The numerals of the scale or chart are designed to indicate tons in car, as called for by the way-bill or manifest, and like in the patents and applications for patent referred to the scale is based on a testing unit and the particular scale seen in Fig. 1 of the drawings is adapted for use in computing the train resistance on an engine which is rated at two thousand (2000) tons and wherein the unit of such rating is a forty (40) ton car; and said scale, as will he further explained is expanded for cars of less than forty (40) tons and contracted for cars of more than forty (40) tons. One of the methods by which this rating is found is fully explained in the patentissued to me and heretofore referred to as Number 715,199, dated December the 2nd 1902.

ln connection with the scale or chart referred to and the perforated disk 15 coperating therewith 1 have provided an adjust able feature, expanded scale or allowance, whereby the machine or device may be adjusted to compute the resistance of cars when employing the said device for engines of different sizes and capacity; this will obviate the necessity of having to have a series of different machines in each oflice adjusted to different sizes and capacity of engines. In this way, 1 not lonly provide an average basis for a train with heavy and light cars mixed, wherein there is conceded weight to the light cars and shrink the weight on heavy cars, but also makes an allowance to engines in proportion to their rating.

rllhe adjustable feature, expanded scale or allowance is employed on the device in connection with the yieldingly held stem 26 and the block 32 of the covering having the series of perforations 31 extending into the said block. On the upper face of the block is provided a scale or chart indicated generally as 46 and made up 0f the following: 300 to 999, 1000 to 1999 2000 to 2999, and 3000 to 5000 These characters indicate the different sizes and capacity of engines within the rating provided for by this scale or chart 46. The iirst is used in connection with the size or capacity of an engine between 300 and 900 tons; the second is used in connection with the size or capacity of an engine between 1000 and 1999 tons; the third is used in connection with the size and capacity of an engine between 2000 and 2999 tons and the last is used in connection with the size and capacity of an engine between 3000 and 5000 tons. 1n the adjustment shown in Fig. 1 of the stem 26 engaging al perforation 31 in the block 32 the machine is being used for the placing of cars in a train, the engine hauling which has the rating of two thousand (2000) tons. If it were desired to use the device in connection with an engine whose rating was anything between 300 and 999 tons the head 27 of the stem 26 would be withdrawn for the purpose of partially rotating the superposed plate 20 whereby the stem would be caused to be inserted in a perforation 31 of the block 32 coinciding with the characters or numerals 300 to 999, or if the rating of the engine were between 1000 and 1999 tons or between 3000 and 5000 tons the adjustment of the superposed plate and the stem 26 would be substantially as that just above described. It is to be noted thatt-he forward portion of the block or member 23 extends across the channel way 22 formed by the covering' 5 and the superposed plate 20 and is in width at this point to extend across one perforation only in the disk 15. In this way, a pin, stem or suitable pencil inserted atrany point into one of the perforations of the disk\15 Aa\nd rotating the disk in the direction indicated by the arrow in Fig. 1, the said pin, stein or pencil will engage with the outside wall of that portion of the block or member 23 crossing the channel 22, just above described.

The arrangement of the scale or chart 45 on the inclined face S of the covering 5 is such, that on a rating of 2000 tons where the unit is a forty (40) ton car, the numeral 1 or the first character of the scale will be removed or spaced from the two thousand (2000) ton mark on the block 32 so that if a stem were placed in the perforation 19 of the disk 15 opposite the 40 ton mark and the disk rotated until the pin engaged with the block 23 the tonnage registering mechanism, consisting of the wheels heretofore described would indicate thereon 40 tons which would be readable through the sight opening 10 in the covering 5.

r1`he scale or chart 45 has been referred to as being expanded below the unit and contracted above the same. 1t is believed that this is readily seen in connection with the above description relating to the tonnage scale or chart indicated as 45 and the adjustable feature expanded scale or allowance indicated on the chart 46 and the disk position or placing of the first character of the tonnage scaleor chart 45 with reference to the 2000 ton rating appearing on the chart 46, by which provision is made for the registration of forty (40) tons between the 40 ton mark on the scale 45 and the block 23 when the same is in alinement with the 2000 tons appearing on the chart 46.

V1n connection with the variable features of the scale or chart 46 and the stem 26 cooperating therewith a 15 ton car placed in a train rated at 300 to 999 tons the registering mechanism will indicate, instead of 15 tons, 17 tons; and the same car put into a train rated at 3000 to 5000 tons, the registering mechanism, instead of registering 15 tons will register 20 tons. This it is believed fully illustrates the expandible feature of all cars placed into a train, where the cars are of less than of forty (40) tons. Now then, a 70 ton car placed in a train rated at 300 to 999 tons, the registering mechanism instead of registering tons will register tons and the same car placed in a train rated at 3000 to 5000 tons, the registering mechanism instead of registering the amount indicated by the way-bill or manifest or the character on the scale 45 corn responding to the tons in car appearing on the way-bill or manifest, will register 57 tons. This it is believed fully illustrated the contractible feature of all cars placed j engine, viz: an engine rated 300 to 999 tons is only required tohaul approximately from eight 8) to sixteen (16) cars to obtain this rating in gross tons; whereas to haul 3099 to 5090 tons enginefmus't haul approximately fifty (50) to seventy-iive (7 5) cars. lWith a small train less cars bind in the curves and there is less wind resistance. Again, on momentum grades, a short train of from ten (10) to lifteen cars7 allows the engine to get a run at the next grade; whereas, a long train holds back and forces the engine to work hard down the first hill to pull the rear part of the train up hill.A

Hence an engine can come nearer to hauling` its full rating of light cars on a 300 to 999 ton rating, than it can on a 3000 to 5000 ton rating, and for this reason I make a greater allowance as the rating increases, which is accomplished by means of the block 3 and its componentparts.

The car tallying mechanism which has been referred to will now be described. There extends longitudinallj7 through the casing 1 a shaft 47 on one end of which and within the casing is provided a pair of numbering wheels 4S and 49 adapted to tally cach movement of the disk l5 and thereby register the number of cars placed in a train. rlhe wheels 48 and 49 are in all respects similar to wheels 37 and 38 of the tonnage registering mechanism. That is each is provided with the toothed portions 4S2L and 49a respectively which extend completelj7 around the periphery of the said wheels on one edge thereof; and on the opposite side of the wheel 48 at a suitable point is provided the single laterally7 projecting tooth 50, which is similar to the tooth 39 on the wheel 35 and the corresponding teeth of the wheels 36 and 37. 1t is adapted in the rotation of the wheel 48, or during each revolution thereof that the tooth 50 will engage with a tooth of the pinion 51, with which the teeth of the wheel 49 are constantly in mesh and with each revolution of the wheel 48 the tooth 50 thereof will move the pinion 51 the distance of one tooth which in turn will move the wheel 49 the distance of one tooth. The pinion 51 is in all respects similar to the pinion 40, wherein the alternate teeth are only half the width of the said pinion. The wheel is keyed or otherwise suitably secured to the shaft 47, preferably by a spline and grooved connection, the spline being indicated as 52 and best seen in Fig. 7. The wheel 49 is slidably carried on the shaft 47 and has the extended hub portion to which is attached one end of a flat coil spring 5.54 which is coiled concentrically about the axis of the shaft 47 and has its opposite end secured to a rod 54, see Fig. 5, on which the pinion 51 is journaled and which is secured in the frame of the machine.

The rod 54 has attached thereto a short vertical standard 55, see Fig. 5, which is placed in close proximity to the outer face of the wheel 49 and the upper end of the standard 55 is in such a position that a pin 5.6 securedto and projecting fromthe wheel 49, when the parts are in a normal position or both of the tallying wheels at 0, will rest on the upper end of the standard 55, substantially as seen in Fig. 5. The continuous rotation of the wheel 49 in the direction of the arrow shown on the said wheel in Fig. 5 will wind up the spring 53a and cause the pin 56 to engage a depression or slot 57 in the standard 55, this will lock the parts in an immovable position. For the purpose of releasing the tallying wheel 49 so a's to disengage the teeth thereof from the teeth of the pinion 51 to permit the spring 58a to automatically return the wheel 49 to its initial position which will return the pin 56 from the notch 57 in the standard 55 to again rest on the standard, as seen in F ig. 5, I have provided for projecting the shaft 47 in the direction shown by the arrow in Fig. 7 and by such movement the spline 52 of the shaft will engage with the face of the wheel 49 and projecting it longitudinally with the shaft until the teeth 49a of the wheel 49 are disengaged from the pinion 5l which will permit of the spring 53a exerting its pressure to return the wheel 49 to its normal position, as there is nothing to prevent the return of the said wheel under the pressure of the said spring after the teeth` of the wheel have been disengaged from the pinion. A finger hole 5S is provided on the outer end of the shaft 47, see Fig. 2, which enables the operator to project the shaft 47 in the manner described. On the shaft is a collar 59 and between said collar and the wheel 48 is a spring 60 encircling the shaft, which, after the return of the wheel 49 to its initial position will return the shaft 47 to its normal position through the pressure on the collar 59. And on a reduced portion 61 of the shaft 47 is carried a coil spring 62 which bears against the end wall 3 of the casing and the end of the sleeve of the wheel 49; its oflice being to act upon the sleeve of the said wheel for the purpose of returning the wheel 49 in a position where the teeth thereof will engage with the pinion 5l, after the said wheel has returned to (V. 1t is believed it will be understood ho f' the wheel 49 returns to its initial position when the shaft 47 is projected, to cor respondingly return the wheel 4S to its initial position, the operator through the linger hole 5S will turn the shaft 47 and thereby place the wheel 4S in its desired position.

The manner of operating the shaft 47 for illustrating on the tallying wheels 48 and 49 the number of cars placed in the train which corresponds to the number of movements imparted to the disk 15 will now beV described. On the shaft 47, see Fig. 3, is carried a ratchet wheel 63 which is adapted to have movement imparted thereto in the direction indicated by the arrow in said figure. For imparting a step by step movement to the ratchet wheel 63 I have provided a spring arm 64 adapted to engage with the teeth of the said wheel and the spring arm is secured at one end to an arm 65 which is fulcrumed on the shaft 47. Adjacent to the arm 65 is carried a stem 66 disposed in a vertical position inthe saidV casing and on the upper end of the said stem is secured a crank arm 67 which is carried across the face of the disk 15 and beneath the superposed plate 20, for a purpose to be described. Attached to the stem 66 and projecting outwardly therefrom is a linger 68, which, when the crank arm 67 is actuated and in turn partially rotates the stem 66, will engage a cam face 69 of the arm 65 and elevating the lower end of said arm will cause the spring arm 64 to move the ratchet wheel 63 the distance of one tooth, which in turn, will partially rotate the shaft 47 and correspondingly the wheel 48. A coil spring 70 carried on the stem 66 and having its ends suitably secured is adapted to automatically return the stem 66 with its crank arm 67 to its initial position and allowthe arm 65 to drop and place the end of the spring arm 64 in a position to engage the neXt tooth of the ratchet wheel 63. To limit the return movement of the stem 66 and operate the crank arm 67 thereof, I have provided the pin 71, shown in dotted lines in Fig. 1, which depends from the covering 5 and is engaged by the crank arm 67 somewhat as shown in Fig. 1.

'Io operate the crank arm 67 for rotating the stem 66 to impart movement to the shaft 47 in the manner heretofore described, the movement of the disk 15 by means of a suitable stem or pencil inserted in one of the perforations 19 and moved through the channel way 22, when the said stem or pencil engages with the free end of the crank arm 67 which lies across the upper face of the disk 15 and also the channel way 22, it will be seen that the said crank arm will be oscillated and by such movement through the pin 68 from the stem 66 elevate the arm 65 for imparting a partial rotation to the ratchet wheel 63 through the spring arm 64 and when the stem or pencil moves off of the end of the crank arm 67, the spring 70 operates to return the stem 66 and the crank arm 67 to their initial position.

I have provided in connection with the car tallying mechanism and the shaft 47 a gong and a trip feature for signaling the gong at pre-determined intervals in the operation of the machine to indicate to the operator that a given number of cars has been placed in a train and that the train limit of cars has been reached. A train limit consists approximately of 60 or 70 cars and to notify the operator when 60 cars have been placed in a train I have provided the bell 72 suitably supported by or on the base of the machine and 73 denotesV a longitudinally carried and rocking shaft or rod 73 journaled in the bracket 74 projecting inwardly from the sides of the casing 1. On one end of this shaft or rod is carried a trip arm 75 which engages with the end of a lever 76 fulcrumed at 77 to a suitable support 7.8 extending up from the base of the casing and the outer free end of the lever 76 is adapted to engage with one end of a bell crank lever 79 pivotally supported at 80 to a stem 81 projecting inwardly from the end of the casing, and on the lower end of the opposite extension of the bell crank lever is provided a knob 82 adapted to engage or strike the bell 72. On the opposite end of the shaft or rod 73 to that which carries the trip arm 75, is carried a second trip arm 83 which projects inwardly and alongside of one of the car tallying wheels and preferably the wheel indicated as 49.

In the rotation of the wheel 49 just referred to, it is adapted to have the pin 56 heretofore referred to, engage with-the trip arm 83 and depressing the same partially rotates or rocks the shaft or rod 73 and by such movement the trip arm 75 will actuate the lever 76 and it in turn will elevate the knob end 82 of the bell crank lever 79. Upon the pin 56 riding 0H of the trip arm 83 a spring 84 attached to the free end of the lever 76 and also to the support 78 will automatically lower the free end of the lever 76 and elevate its opposite end, which, engaging with the trip arm 75 willreturn it together with the shaft or rod 7 3 and the trip arm 83 to their normal position, and simultaneous with the return of such parts the knob 82 of the bell crank lever 79 will sound the gong by engaging with the bell 72.

In Fig. 4 the lever 76, the bell 72 and their component parts are shown in two different positions. In Fig. 5 the trip arm 83 is also shown in two different positions, and also the manner in which the pin 56 engages with the same for depressing the said trip arm to actuate the rock shaft or rod 73 for sounding the gong in the manner described when the train limit has been reached. The pin 56 is so positioned on the wheel 49, that when the wheels 48 and 49 have moved to a position to register 60, the said pin 56 will trip the arm 83 to sound the said gong.

I have described in connection with the tonnage resistance computing wheels 35, 36, 37 and 38 the means by which the same are successively actuated and together with the scales of the device how the actual tonnage of a train is reduced to train resistance. I

will now proceed to describe means by which the. tonnage registering Wheels are returned to then' initial position. The Wheels 36, 37 and 38 have pivotally attached to their side faces the paivls 85, see Figs. 2, 5 and 6 and the said pawls are adapted to have engagement with a longitudinal slotor groove 8G in the shaft 33. And 87 denote flat springs which are secured to short sleeves or hubs of the said Wheels and the free ends of the springs engage with the pavvls 85, somewhat as seen in Fig. 5.

A cradle consisting of the plate 88 and the side arms S9 is pivotally connected at 90 to one of the sides of the casing 1 and normally held in an elevated position by a flat spring 91 secured at 92 to the side 2 of the lasing and engaging with the loiver face of the plate SS. The pinions et), 43 and 4a which have heretofore been referred to as being engaged by the tonnage registering wheels are all carried by a short spindle 93 journaled in the free ends of the side arms S9, see Fig. 5. The forvvard end of the plate 88 is covered With felt or some other suit-- able material 9d and when the plate S8 is depressed, in a manner to be described the felt face 94 of the said plate 88 will engage With the peripheral faces of the registering Wheels for the purpose of holding the said Wheels steady While the said Wheels are being returned to lt ivill be seen that if the plate SS is depressed, so Will the side arms 89 be depressed and disengage the pinions carried by said arms from the registering Wheels and to retain the pinions in their relative positions in which they leave the registering Wheels when the cradle is depressed have provided 'a V shaped trough 95 Which is suitably secured on the bottom of the casing 1 beneath the pinions carried by the arms 89, so that ivhen the cradle is lowered the pinions vvill engage Wit-h the trough and be locked against rotation or accidental displacement, so that when the cradle is again raised the pinions Will be in a position to properly engage Wit-h the registering Wheels aforesaid.

T he direction of movement of the tonnage registering Wheels ivhen train resistance is being computed Will be in the direction of the arroiv shown on Twheel 38 in Fig. 5; but when it is adapted to return the said Wheels to their initial positions at O the direction of rotation Will be just opposite to that just described and the returning of said n heels being` accomplished through the movement of the disk 15 it is natural to suppose that the disk 15 must be rotated in a direction opposite to that above referred to and is indicated by the arrow in Fig. 1. To accomplish this return of the wheels to their initial position the operator ivill press down on a. stem 66 attached to the upper face of the plate 88 of the cradle, which eX- tends up through an opening 9T in the covering rhrough this movement of the scale 9b the cradle vvill be depressed to engage With the registering Wheels and to also disengage the pinions carried by the cradle from said Wheels, in the manner described. rihe pointer or pencil used for actuating the disk 15 vvill then be inserted in one of the holes and a reverse movement imparted to the said disln which, through its engagement of the pin 34E on the shaft also impart a reverse movement to the said shaft and the registering .vheels carried thereby. And a pin 9S which projects outwardly from the face of the ivheel 33 Will engage ivith the extension 99 of a tumbler-pawl 100 pivoted at 101 to the forward end of the plate 83 of the cradle. and through such engagement of the pin 98 with the extension 99 of the said tumbler-pand, the latter will be slightly oscillated on its pivot sufficient to lovter the extension 102 of the tumbler-pavvl into the path of inovmient of the pin 9S to engage the same in the further rotation of the said Wheel. 38 and prevent any further movement of said .vheel 38 which at this time ivill be in its initial position or with the O beneath. the sight opening 10 in the covering lilith this position of the Wheel 38 and its paivl engaging with` the slot or groove in the shaft in the further rotation of the said shaft through the movement of the disk the remainder of the registering Wheels vvill be gathered or returned to their initial positions and their pavvls enter the slot or the groove in the shaft 33 When the entire series of registering' Wheels Will be in corresponding positions ready to begin a new operation. Upon the release of the stem 96 the spring 91 will automatically return the cradle and its parts to their normal positions, and as a means of controlling the movement of the tumbler-pavvl upon the first engagement thereon by the pin 9S l have provided the pin 103, adapted to engage the said paivl in the manner seen in F In Fig. 1 l. have shoivn the preferred arrangement of scale or chart Which is placed on the bevel face S of the covering and b v the same am enabled to reduce train tonnage to train resistance. is ivas above described all cars placed in a train of less than forty (#10) tons are expanded and all cars of more than forty (40) tons are contracted. So that on the basis of 2000 ton rating and a forty (i0) ton unit a train made up of fifty cars, of forty (e0) tons eaclnOOO tons will be registered on the registering mechanism. And if the train is made up of S3 cars, of Q0 tons each. 1G60 tons .vill be registered on the registering mechanism or if the train is made up of 36 cars, of tons each, tons Will bel registered on the registering mechanism.

The perforations 19 in the disk 15 represent one tooth each of the 'toothed portion of the said disk or are disposed in the said disk to coincide with the teeth thereof, and each perforation or each tooth represent one ton. So that if the stem 26 of the block 23 coincide with 2000 tons, between the said block and the 407 of scale 45 there will be 40 perforations, equaling 40 tons. And the scale 45 between l and 40 has been contracted as is readily seen by doubling the characters at certain points for the purpose of equating the proper resistance to cars below the unit when the resistance thereof is computed in connection with the scale 46 in manner described; and likewise that portion of the scale above the unit or 40 ton mark is contracted but in a greater proportion than that shown on the portion of the scale below the unit for the purpose of equating the proper resistance to cars above the unit. Thus it will be seen that the adjustment of the scale 46 to the scale 45 permits of the hauling of a greater tons resistance in heavy cars than is permitted in light cars. And to give a better understanding of such equation of tonnage resistance, and particularly on an engine rated at 2000 tons, the said engine will haul only 1660 tons of 20 ton cars, 1890 tons of 30 ton cars and 2000 tons of 40 ton cars which is the unit of rating; while the same engine will haul 2120 tons of 50 ton cars, 2310 tons of 60 ton cars or 2520 tons of 70 ton cars. This it is believed has been fully explained in connection with the scale 45, wherein a 20 ton car measures 24 ton resistance; a 30 ton car, 32 tons resistance while a 40 ton car being the unit of rating measures 40 tons; a 50 ton car measures 47 tons resistance; a 60 ton car, 52 tons resistance and a 70 ton car 56 tons resistance. The above have been selected at ran? dom, but a careful examination of Fig. l will substantiate this showing.

By beveling the covering 5 as at 8 and placing the scale 45 thereon it brings the characters of the scale in close proximity to the perforations in the disk 15 so that there is little danger of the operator making a mistake when placing a pointer or pencil into a perforation of the said disk alongside of a character designating tons in car, the resistance of which is to be computed.

Attention is here called to the fact that in computing the resistance in trains of cars, the pointer or pencil used to operate the disk 15 will be inserted into the 1perforation in the disk opposite the number on the scale corresponding to the tons called for by the way-bill or manifest, but through the mechanism described as coperating with the said scale and disk the tonnage registering wheels will register amounts at variance with that called for on the scale, or in fact reducing tonnage to train resistance.
