Tooll idiom it may concern:

Be it known that i, JOHN M. DALY, a citieago, in the county of Cook and State of Illinois, have invented certain new and' useful improvements in Computing-Machines5 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 coniputing machine, and has for its object the equation of train tonnage or for computing the tonnage resistance iii-railway trains, the object being to reduce or adjust the loading of engines from an actual weight to a drawbar pull. y Attention is called to several patents issued4 to me on December 2nd 1002, two of which are lnumbered 715,109 and 715,201

computing the tonnage resistance of railway trains, and while the results to be obsiinilar to the patents referred to, the method of and the construction of the mechanism are The 'method in vogue on railroads for making up trains or loading engines prior of loaded and empty ears in train, reducing empty cars to a loaded car basis. Onsome (2) empty cars equal to one (1) loaded car, hence an engine rated at twentyfive (25) loads would haulA twenty -(20) loads and ten (10) empty cars. On other roads they used a basis of three (3) empty cars equal to two .(2) loaded ears, others five (5) empty cars equal to three loads, etc. At that time this method was reasonably accurate, as cars were of almost uniform capacity and weight, viz., fifteen (15) and twenty (20) ton capacity. With the introduction of large engines, and the reduction of grades about 1897, came the large capacity car of fifty (50) ton capacity, against the standard fifteen (15) and twenty (20) ton capacity cars, making it impractical to rate and load engines on the car-haul plan was next tried, this plan has on several roads -proved a failure and frequently reing delayL to train and creating .additional leleven hundred and twenty (1120) chances for accidents. The manifest or way-bill that accompanies loaded cars shows the tare, net and gross Weight of car and and build up trains on the tonnage basis'.

The gross tonnage plan is not a correct basis, for the reason, that it does notrecognize or provide for the additional power required to haul a ton of car as compa-red to a ton of contents, although all experts concede that the same engine can haul a greater gross tonnage of large capacity heavy loaded cars than it can haul in small capacity light loaded cars, for the reasonthere are elements of friction due to the number of cars used in taking care of a given tonnage of contents. For example: an engine rated at twenty-one hundred `(2100) gross tons is attached to train composed of thirty (30), seventy ton cars equal to twenty-one hundred tons, will have no ditliculty in hauling such a train, in fact it should have six hundred or seven hundred tons more.4 On thenex't trip over the same grade the saine engine has twenty-one hundred 2100) gross tons of fifteen (15) ton cars, it cannot possibly haul it. Again 'on another trip over the same grade the same'engine has twentyone hundred (2100) tons of forty (40) gross tons in fifty-three (53) cars, it is able to h aul the train in the allotted time. Each standard freight car has eight (8) wheels, eight (8) journals and measures about forty (40) feet in length overall. twenty-one hundred (2100) tons is in seventy (70) gross ton cars we have only thirty (30) cars, two hundred and forty (24:0) wheels and journals and twelve hundred ,(1200) feet of train. ln forty- (A10) ton cars we have fifty-three (53) cars, four hundred and twenty-four (424;) wheels and journals and twenty-one hundred and twenty (2120) feet vof train and if in fifteen (15) ton cars, we have one hundred and forty (140)' cars, wheels andl journals and fifty-tix hundred (5600) feet of train. With seventy (70) gross ton cars, we have friction on two hundredand have twelve hundred (1200) feet of surface for Wind resistance; we have the henelit of inomentumvwhen one half/the train passes loo Vforty (24.0) journalsland at Wheel to rail on two hundred and forty (240) wheelsywe over the summit of grade to help over an adjacent grade again; we have only Jtwelve hundred (1200) feet of train to bind in one i fifty 50) cars of forty (40) tons each, we

This tons each next the engine and the fteen ratio does not exist to the same per cent. on (15) ears of fifteen (15) tons each next the heavy grades where the rating is five huncahooseand the engine can haul seventy-five dred (500) to one 'thousand (1000) gross (75) additional tons or a total of nineteen tons as where the grades are light and en-- hundred (1900) tons. In the first case, when giiies are rated at fifteen hundred (1500) light cars were next the engine We conceded to twenty-,tive hundred (2500) tons, for the twelve (12) additional tons per car to the reason, that theY smaller the rating the less engine for increased resistance of a fifteen cars are required and the less friction, wind (15) to a fort-y (40) ton car, also for the adresistance and resistance due to distance of ditional resistance due to heavy cars at rear weight from power. end. In the second case, with the light cars llaving shown the fact that a ton of car at rear, we 'reduce that feature of the conceshas a greater draw-bar pull than a ton of sion .and allow the engine six (6) tons per contents, I wish now to show that the draw-v car on the fifteen (15) light cars for differbar pull or train resista-nce will vary on ence in weight compared to forty/(40) ton heavy and light cars according to their locacar, no concession made for light cars ahead. tion in train or distance from the engine.

Again rear of train near caboose and light cars when an engine is tested on basis of forty placed at head end near the engine, the (40) ton cars and rated at, say, sixteen hunheavy cars at rear draw hard and tend tO- dred (1600) tons, no concession is made for ward straightening out train in curves creany car of forty (40) gross tons `put in train ating additional friction of wheel liange to between the first and fortieth car, as the rail, the i'everseeect is felt when the heavy engine demonstrated its capacity to haul cars are hauled near the engine. Hence in full rating of such cars up to a limit of forty order to equalize, adjust and load an engine (40) cars; however, when a forty (110) gross on an equated tonnage or draw bar pull ton car is placed in train at the rearof forty basis, it is necessary to not only provide for other cars on a 'sixteen hundred (1600) ton the difference in the resistance between light rating, it must receive an additional allow and heavy cars, but, to also provide for the ance according to its location behind the fordifference in the resistance or draw-bar pull ticth (LlOth) car, due to length ofitrain redue to location of each weight of car in the sistance and also to the resistance due to train andthe distance of the'weight from the placing cars of less than forty (40) tons engine. ahead of the fortieth (40th) car.

in oider to provide for the difference in The invention has for its further object, resistance of light and heavy gross weight a machine for equating the draiv-bar pull cars, my plan is, to test the engines with of cars of different gross weight at different train composed of cars all of one gross locations in train, preferably, from the acweight, say forty (40) gross tons each. Aftual weight of car and contents as shown on ter arriving at a proper rating on forty (40) the manifest or way-bill that accompanies ton cars, determine the resistance of iifteen each car; by means of a suitable registering (15),twenty (20), twentyive (25) ton, etc., device or display, having a series of keys at different locations in train. For example, for operating the same, which said keys have on a of two-thousand (2000) tons, an invariable movement for a predetermined different weights oiicars. The o'bject being,

that if an operator presses down the kcy numbered H; 15, 16, ten consecutive times it registers on the registering device one hundred seventyY (170) tous, instead of one hundred titty (150) tons; two tons allowed each car on account-ot their representing tons less than the testing unit. ltress the same key ten (10) additional times 'and the registering device will record one hundred eighty (180) tons or three tous per car additional, one ton more being allowed for length 'o1' train or distancetrom the power. Press the same key ten (10) additional times and it registers on the recording devicetwo hundred (200) tons or two additional tons, which is allowed for the increase distance from the power; this ratio on the basis that the engine rated at sixteen hundred (1000) tov two thousand (2000) tons. It the engine is rated at seven hundred (700) to twelve hundred (1200) tons the allowance in each instance would be less; butnif rated two thousand (2000) to twenty tive hundred (2500) tons, a greater allowance per car would be made. Again, if after the placing of the thirty light cars in the train, such as indicated by the key, you add tive (5) cars of forty (40) [tons each, to 'record this additional tonnage the Vdraw-loa .ton unit cars.

The next ive (5) cars added to the train, if of seventy ton cars the ton key is pressed and at each pressure oif the seventy (70) ton' key there will be registered' on the recorder sixty two (62) tons making a total of 310 tons.

The adjustment of th'e keys may be such that the increase in their stroke may be after tive successive strokes on one key or upon five dii!- terent keys or adjusted to suit any number of strokesl as may be desired and as required for different ratings.

in order that the invention may be more fully"understood reference is had to the accompanying drawings forming a part oi this specification, in which;

The'device may be portable,v as shown in the drawings or otherwise as may be desired ando'f a siie most convenient.

The devices* tached portions of diiiercnt forms of a tapey bar pull of same weight of car at diii'erent- In the cas' iso may form a part of the standards 2. The

reel 8 is supported on a shaft 10 extending longitudinally and parallel with the, shaft 4 and the same is journaled in the brackets '11 which extend up from and form a part of certain standards 3. To insure the tape or scale being fed uniformly from the reel 7 to the reel 8 I provide for frictionally feeding the said tape or scale, which is accomplished by the

rollers

12 and 13, the former bearingupon the surface of the tape and impinging the same against the surface of the wheel 5; the roller 13 bearing against the surface of the wheel 5 as shown and frictionally holding the same during its rotation, both the

rollers

12 and 13 are yieldingly held by means of the springs 14.' The roller 12 is carried inthe swingably supported arms 15 carried by a shaft 16 extending parallel with the shaft 10 which in turn is supported by arms 17 forming a part of the brackets 10. The roller 13 is snpported by arms 18 which are swingably carried on the shaft which supports the reel 7. In the movement of the wheel 5 the tape or scale G is unwound from the reel 7 and wound upon the reel 8, for thc purpose of registering the tons of resistance indicated by the operation of certain keys to be described. The winding of the tape on the reel 7 is assisted by a spring drum 1S from which a tape or cable 19 is fed and one end attached to and adapted to be wound on a reel 2O carried by the shaft 10. In rewinding the tape or scale (3 on the reel 7 the same is assisted by a spring drum 21 from which a tape or cable is fed one end of which is attached to and wound upon a drum 23 attached-to or carried by the shaft supporting the reel 7.

The wheel 5 is adapted to be actuated through the tape 6 and pawl 24 carried by a rod 25, which said rod is mounted in a link frame which will be described. vT he pawl 24 f being yieldingly held to its work by means of the springs 26 5 the pawl heilig so disposed that in its normal position it is free of the ratchets on the wheel 6 to permit the latter to bel turned in opposite directions without necessity of having to disengage the pawl, the purpose of which will be described.

The link frame to which attention was called comprises a shaft 27 extending longitudinally in the frame and journaled in the Standards 28 atopposite ends thereof and at- In the tached to the ends of the shaft 27 is shown the bars 29 extending forwardly and connecting the free ends of the bars 29 is shown a rod 30. Extending up from and attached to the opposite ends of the rod 30 are shown the link bars 31 and connected to the u per end of the link bars 31 is the outer end o the rods 25, the inner end of the rods 25 connected inra link bar 32 which extend from the shaft 4 which support the i'nner ends thereof out and beyond the rods 25 and their ends are connected by the short rod 33. The

arrangement here shown has been made necessary on account of the construction of the wheel 5 and the arrangement of the link bars 31, 32, and the rods 25; butthis arrangement may be modified and rearranged desired. The link frame consisting of the

bars

29, 31, 32 also the

rods

25 and 31 is held normally in a raised position, and yieldingly held in such position by means of the springs 34 carried by the shaft 27 and bearing against the under side of the bars 29, also the springs 35 carried by the shaft 4 and bearing agalnst the under side of the rods 25 as shown.

36 indicates a shaft or rod, its opposite ends journaled in the upper ends of the standards 23, and 37 denote a series of key-v bars having their inner ends pivoted on the shaft 36 and the bars separated by the spacing collars 33 carried on the shaft 37; the bars 37 extend forwardly inclined slightly upwardly and pass above the rod 30, with the lower edges of the bars 37 lying in close proximity to the upper face of the rod 30. The bars 37 pass out of the casing 1 through the slots 39 in which the key-bars are adapted to have vertical movement and the key.- bars are alternately short and long to economize in space, and are provided on their outer extremities with the short arms 40 to which is attached a key or-button 41, upon the face of which .is adapted to be placed certain numerals representing cars of certain tons, as called for by the way-bills or manifest, which will be further described.

42 denotes aflongitudinally disposed shaft which is journaled in the upper ends of the standards 3, and upon said shaft is carried a series of stop members 43, in practice one for each of the key-bars 37. The said stop members are provided with irregular peripheries, to be further described, and have the extended hub portion 44, to provide a suitable bearing therefor on the shaft 42. The stop members arev so arranged on the Yshaft thatthey are alternately disposed with body through which the shaft 42 extends and to adapt the bars 45 to have an extended movement across the axis of the shaft which 'is occasioned by the depression of the keyascesi the lips or depending ears 4S of the succeeding arms 45 are shorter than those on the preceding bars 45, the purpose of which will `,be'takeul as indicating-g also be described. The key-bars are adapted to lie-normally held in a raised position, with vthe lips 48 of the bars 45 in their extreme raised position above the stop members' described, accomplished by me'ans of spring arms 49 bearing upwardly against the lower edge of the key-bars 37, with a coil of the spring, coiled around the shaft 27. These spring arms serve also, to return the key-bars to their normal position after eachdepression whenvthe hand or finger of the operator 1s released therefrom.

Referrlngagam 'to the key-bars 37, attention is directed to Fig. 1 -which shows inplan the buttons or keys 41; these keys are provided with suitable numerals and are adapted to register the tonnage in cars ranging from fourteen (14) tons to seventy-three 7 3) tons. It. will be observed, as was stated above, that each of the keys p ovided with three numerals. The first ke beginning with the left hand side of th machine, represents a car weighing fourteen (14), ftecn (15) or` sixteen (16) tons, respectively, and each succeeding key thereafter represents carsthree tous more than the preceding keys.` This arrangement is made for the purpose of economizing in space and the registering deviceis conformed thereto, but it is not intended to put a limit on the number ot' keys nor what tons in cars each key shall represent; 'for the reason, that a machine may ,be so constructed that a fifteen (l5) ton car will be represented by one key and asixteen (.16) ton car by another key. There is no limit to this arrangement and the device here shown is to illustrate how in4 practice the device maybe made.

Referring now to the stop members which I have indicated as 48, it Wlll be observed from the drawings and especially Figs. 3, 4,

5, and 7, that the irregular faces thereof vary on nearly all of the stop members. In Fiv .3

which represents an end View from one side of the machine, the stop member there shown may be taken to indicate a seventy or a seventy-one (7i) ton stop member, while in Figs. 4 and 5, the stop member may a tort y (40) ton stop member, and in Fig. Y, three dili'erent stop members are shown which may be taken as reprtsenting' fifteen (15), thirty-tive (35) and forty-five (45) ton stop members respectively', Thermachine in this case, maybe taken as being based on a sixteen hundred (1600) ton rating, the unit of which is a i forty (40) ton car; therefore, all of the stop members would be adjusted to this rating; and the depending` lips or ears 48 ot the bars 45 are in length tocorrespomtto the stop members with which they co-act. In other words, taking for example a forty (40) ton stop member and the position in which it is lshown in Figs. 4 and 5; it a forty' (40) ton car were placed in a train in the lirst forty (40) cars, the stroke ot a forty (40) ton keybar would be only sutlicient to move the registering tape 6to record forty (40) tons, the depression. oli' the key beingdetermined by the distance between the upper squared face of the forty (40) ton stop member as shown in the figures, and the lower edge of the ear or lip 48 of the barv 45 co-acting; with such forty (40) ton stop member and attached to the forty (40) ton key-bar.

lin computing the tonnage resistance of the cars as they are added to the train, I have provided as was intimated in the fore part of the specification, to allow somuch resistance tor cars of diferent weights and in series; so that in making up a train if ten cars of fifteen (15) t-ons each are placed in thetrain next the eng-ine, each car will register on the recording device seventeen (17) tous respectively or in the main one hundred and seventy (170) tons. At this juncture, mechanism would be brought into play for automatically changing the position of the fifteen (15) ton stop member and in fact all the stop members simultaneously,

so' that by placing ten (10) additional `tifteen (15) ton cars' in the train, the movement of the fifteen (15) ton key-bar and its bar 45 would move so as to register on the rec'ordingdevice eighteen (18) tons'for each depression of the key-bar or one ton additional for cach ot the ten (10) cars .110

added to the train, amounting to one hundred and eighty (180) tons. For example, take the seventy (70) ton key-bar, and i in making up the train, we shouldA place ten 10) seventy (70) ton cars next the engine, the depression of the seventy (70) tons keybar ten (10) times wouldv register on the recordingdevice six hundred (600) tous or sixty (60) tons for each car, the reasons for which have been heretofore stated. Or if in placing a sixty (60) ton car next the engine, a depression of the sixty (00) ton key-.bar would record tittysive (55) tons; or a depression of a forty-eight (48) ton key-bar, the same will re'ord a'iproximavtely forty-six (46) tons; the depression of a thirty-six (36) ton key-'bar will record approximately thirty-seven (37) tous; the depression-of a twenty-seven (27) ton key-bar will record approximately twentymine (29) tons. In other words, the tonnageotcars iso ia i

below the` unit is expanded and that above the unit contracted, and the nearer the car comes to the testing unit, the less variation in the'resist'ance.y The stop members are so made and the lips t8 of the bars 45 so adjusted with reference to the distance of travel to lthe face of the stop member, that in no matter what position a car is placed iii the tr'ain, the pressure upon a key-bar represent-ing such a car will equate on the register its proper'resistance. In the machine here shown, each of the stop members is provided with eight (8) irregular faces which are adapted to limit and regulate the distance of travel of each of the key-bars as they are depressed. The examples above given With reference to thel'placing of certam cars 1n a train Were equated as though each stop member had ten irregular faces,

rather than eight, and I wish it to be understood that vin computing the resistance the machine may be adJusted bythe placingof stop members whichwill equate in series of eight cars more or less. Each stop member is made to suit the requirements of its office. and eachlip 48 of the bars 45 are made in lengths, to have a stroke which will equate the proper resistance in a car whether vthesame -1s 1n the first series of eight, or

Wherever elsel it might be placed in the y ltrain or Whatever tons arev represented by such a car as itappears on the way billsor manifest. And devices are provided which will be described for changing the position ofnot only one but of all the stop members at predetermined intervals, or after each eight cars have'been placed in the train, if the machine is so made and the shape of the stop member is to conform to cars in series A described, is also adapted to servel as atallyofeight. ,This mechanism which will be ing device for `'registering the number of carsl placed in a train.' It Willf1 be noticed from the drawings that the peripheral edges of the stop members as you leave those rcpresenting the unit of forty (40) tons and upon opposite sides thereof, are more and moreirregular, that is to say, the otfsets become greater, While the stop members which' represent the unit of forty(40) tons 'are provided with a series of contact faces which are similar the remainder of the contact faces are more and more depressed.

This is tov accommoc ate the placing of a' given number of forty (40) ton cnrs in the train, and lwhen placing a forty (40) ton car after the train has reached a certainlength,

the face o f the. forty (40) ton stop members is provided with a series of increasing irregular portions to properly compute the resistance in the .forty (40) ton car whenl placed inthe train as stated.

The shaft which has been referred to as l0 is here shown in two parts and connected 'sewer by the sleeve 9h at or near the outer end,

the shaft l0 carries a pair of gear wheels 5() and a pair of

unit wheels

51 and 52. The

`gear wheels will haveteeth in number to correspond to the acting faces of the cams. As was stated, the cams in the present application are provided with eight portions, therefore the wheels 50 are each provided with eight teeth. This will also be true of the unit wheels which will register with every depression of a key-bar 37. This is accomplished by means of a gear Wheel 53 corresponding to the gears 50 and is carried on the outer end ofthe shaft l';v this shaitt like the shaft 10 is in two parts and is connected by sleeve 54. To operate the gear 53 for transmitting power to one of the gears 50 with each depression of the lreyfl. have provided aratchet bar 55, the lower end of which is carried by the rod 30 -formv ing one of the elements ot the link-trame. The upper end of the ratchet bar has a toothed portion adapted to engage with a ratchet wheel 56 carrierlby the shaft 16, and may be integral with the wheel 53, it desir able. A springr 57 attached lo the shaft 30 and bearing against the rear of the ratchet bar 55, serves to hold the same in position for engagement with a tooth oi the ratchet lwheel 56; so that with each depression of a key-bar 3T, the tooth of the ratchet bar will impart a partial rotation to the shirt, 'by engagement with a tooth of the rtchet wheel and cause the wheel 53 to more one oit the wheels 50 the space ot' a tooth and regster the same on the unit or tallying wheel 5l. \Vith every complete revolution of the wheel 51, it is ada ted to move the lunit wheel 52 the space ot one tooth, for the purpose which is clearly apparent and well known with this form of tallying device. I accomplish this by securing a segmental gear 57 havingpne tooth on the shaft i6, the tooth ot which is adapted to inter-mesh with the teeth of the gear wheel 50, adjacent A to' the unit 'Wheel 52. And as was stated above, the actuation of the tallying device is also employed for the purpose ot imparting a partial rotation to the shaft'l which carries the stop members after a given number of strokes have been applied to any one key-bar or a series of such key-bars in succession. This is accomplished by a gear wheel 58, in all respects similar to the

wheels

50 and 53, and is secured on the shaft 4Q and interineshes with one'of the wheels 50, best seenin Figs. B, 4 and 8.

The registering tape or scale 6 is provided with suitable signs or marks .and numeralsv llO l0, or of any other suitable form. The tala kev.

distance, a hand wheel (il has been provided seci'ired upon the oiiter.ciid ot `the shaft l as seen in the tigures andthe arrangement of the ratchet teeth Q4.- desciibed as being norinally held' away from the teeth oit the ratchet wheel (i, will pei'init'ot the reverse ilnoveinent. just. described, andthe pawl 2l is .so disposed that a preliminary depression must be given to the key-bars 23T before the pawl engages with the teeth ot' the ratchet. wheel. This preliminary movement ot the key-bars is made without atl'ecting the position of any of the parts by leaving a sutlicient amount of space between the shaft or bar 30.and the lower tace of the key-bars 37 when they are in their normal position. lt

' is adapted to have the pawls 34 with three ene'aeine' ioints onev shorter than the other a u e: l s

so as to provide their ready engagement with any one tooth of the ratchet wheel (l as the link-trame is depressed. The means for reversing the tallying device is similar to the tonnage registering mechanism and is accomplished by means of a hand wheel (r2 on the outer end of the shatt. 1G, and upon the outside ot' the device which is also the ease with the hand wheel 6l.

in the present device, the arrangement of the irregular a ct-ing faces ot the stop members is to provide tor making up trains ot cars 't'roin the power rearward or when switching in cars at points remote from thepower. rlhe reverse of this-may be aeconiplished by i'eversing the arrangement. oi the stop niembers and provide for picking up cars next to the engine orpower to save backing engine and cars into side tracks, and further, will save equating ears in train when more are added. rlhis and many forms of arranging and equating with the devices here shown,

may be provided, and l do not wish to he confined to the specific structure as herein shown.

I have provided the casing with a cover i3 hinged at (it and adapted tobe locked at. (if). The same may be swung backward to expose to view the operative parts of the. apparatus and give access thereto.
