COMPUTING-MACHINE.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed April 11, 1904. Serial No. 202,552.

Be it known, that I, JOHN M. DALY, a citizen of the United States, residing at Chica 0, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Com uting-Machines;

and I do hereby declare t at the following is a full, clear, and exact descri tion of the invention, which will enable ot ers skilled in the art to which it appertains to make and use the same.

This rhvention has reference to a computing machine, and has for its object the equation of train tonnage or for computing the tonnage resistance in railway trains. The" object being to reduce or adjust the loading of engines from an actual weight to a draw-bar pull.

That the invention may be more fully understood, reference is had to the accompanying drawings forming a part of this specification, in which Figure 1 is an elevationof one end of my improved machine, with the casing shown in section; Fig. 2 is a plan view of so much of the machine as will illustrate my improvements, and showing the casing in section; Fig.3 is a vertical sectional elevation taken adjacent 'to the tonnage recording mechanism, and looking into the machine just opposite to that shown in Fig. 1; Fig. 4 is a Like numerals of reference indicate cor-- res ending parts throughout the figures.

n the drawings, 1 indicates a casing which may be of suitable form and in'which arts of mydevice are contained. The eviee may be portable as shown in the drawings or otherwise as-may be desired, and of a size most convenient. In the casing are carried the standards 2 and 3, supported upon the base of the casing and suitably connected together, the parts which are shown in Fig. 1 being arranged in series to support certain operative parts in the length of themachine. In the standards 2 there is journaled a shaft 4 and on this shaft are carried certain recording wheels which will lie hereinafter referred to and described more in detail."

niachine in the application referred to, a. link-frame adapted to be actuated by any one of a series of key-bars for the purpose of registering on the recording wheels the tonna e resistance of cars called for by any one of the key-bars which may be actuated, the link-frame being suitably connected with the recording wheels for this purpose. The link-frame comprises a shaft 5 extending longitudinally in the frame and journaled in the standard 6 at opposite ends thereof, and attached to the ends of the shaftr5, are shown the bars 7 extending forwardly, and connecting the free ends of the bars 7 is shown a rod 8. Extending up from and attached to the opposite ends of the rod 8 are link-bars 9, the upper end of which-is pivotally connected at 10 to an arm 11- carried by and extending forwardly from the shaft 4, the purpose of which will be further described.

12 denotes a rod, its opposite ends journaled in the upper ends of the standards 6, and 13 denote a'series of key-bars havin their inner ends pivoted on the shaft 12 and the bars 13 are separated by the spacing collars 14 carried on the shaft 12; the bars 13 extend forwardly inclined slightly upwardly and pass over the rod 8 with the lower edges of the bars 13 lying in close proximity to the upper face of the rod 8. The bars 13 pass out of the casing 1 through slots 14 arranged in the front wall of the casing in which the key-bars 13 are adapted.

to have vertical movement, and the key-bars are alternately long and short to economize in space, and are provided on their outer extremities with the short arms 15 to which is attached a key or button 16, upon the face of which are adapted to be placed certain numerals representing cars of certain tons as called for by the way bills or manifest, substantially as inthe application referred to.

17 indicates a longitudinally disposed shaft which is journaled in the 11 per ends of the standards 3, and upon said shaft is carried a series of sto 3 members 18, in practice one to co-act wit 13. The said stop members are provided with peripheries which have graduated depressed portions extending from a point remote from the center of the stop member shaft and terminating adjacent thereto, and

the said stop members have the extended hub each of the key-bars portions '19 to provide a suitable bearing therefor on the shaft 17. The stop members are so arranged on the shaft that they are alternately disposed with vertically movable bars or arms 20, which at their lower ends are pivotally attached to the keybars as at 21, and are further provided with the elongated slots 22 in their body through which the shaft 17 extends and to adapt the bars 20 to have an extended movement across the axis of the shaft which is occasioned by the depression of the key-bars 13 to which the bars 20 are attached. Each of the bars 20 are provided with the depending ears or 15 lips 21, which overlie the peripheral edges of the stop members 18 and are adapted to engage or abut with the stop members 18 when the keys are depressed, serving to limit the stroke of the keys. The arms 20 are adapted 20 to be and are preferably uniform in length, while the lips or depending ears 21 of the succeeding arms are shorter than those on the preceding .bars 20, and while it is'prefs erable to construct the bars 20 as just de- 25 scribed, it is to be understood that no limitation is to be put upon thelength of the bars or their lips. The key-bars are adapted to be normally held in a raised position, with the lips of the bars 20 in their extreme .50 upper position raised above the' stop members described, accomplished by means of springs 22 bearingv upwardly against the lower edge of the key-bars 13, with a coil of the spring wound around the shaft 5. These springs serve also, to return the keybars to their normal position after each depression when the hand or finger of the operator is released therefrom. Any number of key-bars may be employed, and they 40 may be disposed as shown in Fig. 2 of the drawings, each of the keys representing cars of a s ecified tonnage and on the button 16 of sai keys is adapted to be placed one or more numerals indicating to the operator the tons represented by the keys, substantially as is disclosed in the application rcferred to and as herein shown. In this application, the stop members have ten graduated portions with :which the lips 21 of the bars 20 are adapted to co-act, and in Fig. 1, the stopemember there shown in elevation, may. taken as representing a seventy (70) ton stop member, while in Fig.

3, the stop member there shown may be taken as representing a forty (40) ton stop member. As in the application referred to, the machine here shown may also be taken as based on a sixteen-hundred (1600) ton rating,'the unit of which is a forty (40) ton car; therefore, all of the stop members would be adjusted to this rating and the de ending lips or ears 21 of the bars 20 would made in lengths to correspond to the stop members with which they co-act. This 06 would necessitate maln'ng the stop members which represent the unit of rating with a series of uniform portions on their peripheries to admit of placing a given number of cars in a train without showing any creased resistance until after reaching a cerwe tain length in the train.

It is to be understood in this, as well. as in the application referred to, that the ma-- chines may be constructed to represent engines of any rating which may vary from eight hundred to twenty-five hundred tons, more or less, and that the stop members and bars 20 would be made to suit this rating.

It is also'understood that in making up a train of cars, it is adapted to compute the increased resistance after a series of cars have been put in the train, and it was shown in the application referred to that it was adjusted to cars in series of eight, while in this case, the stop members are adjusted to compute them in series of ten and devices are provided so that after ten cars have been assembled in series, the stop member shaft will be caused to make a partial rotation which will increase the length of stroke of the bars 20 during; the placing of the next ten cars, and simultaneous with the next ten strokes the stop members will be again automatically adjusted to give additional movement to the bars 20 and such movement is carried on throughout the operation of the machine which is clearly apparent.

The mechanism which operates the stop member shaft is also adapted to actuate a 1 tallying device, in all respects similar to that shown in the application referred to for registering the number of cars placed in a train. A detail descriptionof the tallying device is unnecessary except to say that 10 units wheels 23 are carried on a shaft 24- which is' journaled in a bracket 25, and the shaft 24 is actuated by means of a gear Wheel 26 meshing with a gear wheel 27, the latter being carried on a shaft- 28 also 10 -journaled in the bracket 25 and the shaft 28 has anintermittent movement through a ratchet 29 actuated by a ratchet arm 30, the lower end of which is carried by the shaft 8 and the upper end thereof, held for engage 5 ment with the teeth of the, ratchet wheel by means of the spring 31. Thus it will be seen that upon the actuation of a key-bar, the shaft 8 is depressed and through the ratchet arm 80 the shaft 28 receives a partial 0 rotation suflicient to move the wheel 27 the distance of one tooth and also the wheel 26 which meshes therewith. Upon every complete revolution of the shaft 28, a segmental toothed wheel 32 is brought into play for actuating one of the units wheels 23,. which is accomplished by providing a wheel 33 on the shaft 24: with which the single tooth of the segmental gear intermeshes substantially as n the application referre to. And upon every complete revolution of the shaft 24, the shaft 17 .is caused to make a partial revolution which is accomplished by'me'ans of a gear wheel 34 carried by the carried on the shaft 4. On the face of this wheel is provided a series of suitable signs and numerals indicating tons. In this instance, the signs are transverse lines accompamed by numerals indicating from O0- to 990 tons, so that'in the actuation of,

the key-bars in one complete revolution of the wheel 35, the operator may record from 00 to 990 or 1000 tons. There is associated with the wheel 35 a supplemental wheel 36, which is also carriedon the shaft 4 and adjacent to the wheel 35. On theface of this wheel, is arranged a series of signs and numerals for the-purpose of registering during thecontinued rotation of the recordof the wheel 36, at stated intervals and providing numerals such as 00, 10 20,

etc. Mechanism is provided operating synchronously with the movement of the keybars and when a complete revolution is madefby the wheel-'35 for registering ton-' nage from 1000 and upward. In other words, with every complete revolution of the wheel 35, the wheel 36 will make one tenth of a revolution. The movement of the wheels 35 and 36 is caused primarilyv by the actuation of the key-bars 13 and with" the assistance of the link-frame described, The wheel 35 is provided with a flange having the internally arranged ratchet face 37, the ratchet teeth of which may be" spaced the distance of a one ton mark appearing on the surface of the wheel, five, ten, more:-

or less; in this instance, the teeth are ar-* ranged at'every five ton mark.

38 is a pawlco-acting with the ratchet,

teeth of the wheel and is pivotally sup ported at 39 on the outer end of the arm 11, and the pawl is held under the tension of a spring 40 to insure its contact at all times with the ratchet teeth. Thus it will be seen, upon the-depression of a key-bar,

thelink 9 will move downwardly bringing with it the bar 11 and the engagement of the pawl-38 withthe ratchet teeth of the wheel- 35 will impart a partial revolution thereto, which is predetermined by the length of the key-bar which is depressed and the position of the stop member with which it co-acts. Upon the release of the key-bar, the same will return to its normal position in'the manner specified, and the link-frame will be returned to its normal or raised. osition carrying with it the arm 11 an the pawl 38 by means of a spring-arm 41 bearing against the lower face of the bar 7 and hav ing a portion coiled around the shaft 5.

The wheel 36 has a flange similar to the, wheel 35' which is provided with thezinternally arranged ratchet ring 42 corresponding to the ratchet 37 of the wheel 35. Go-

- acting with'the ratchet teeth 42, is a spring heldpawl 43, which is pivotally connected at 44 to the outer end of a bar 45 which is attached to or is integral with a' stem 46 fournaled in the bracket 25. To obtain the "every complete revolution of the wheel 35, I have provided a short arm 47 carriedupon the opposite end of the stem 46, which projects into the path of a in 48 extending rradially from the side of tie wheel 35, and

.the stem 48 at the proper time during the rotation of the wheel 35, engages with the arm 47, and by such engagement imparts a partial rotation to the stem 46, which will oscillatethe arm 45 and throughthepawl 43 attached thereto, "partially rotate the wheel 36,.the stem 46 and the arms '45 and 47 beingheld' under thetension of a suitable spring, not shown, as soon as the in .48 passes beyond the end of the stein-A ,the spindle 46 will return the parts to the position as shown in thefiguresa A frame 49 is provided which serves. as a-support for the spindle 46 and from such frame extends a lug or lip 50 with which the arm 47' abuts when in its -normal position and insures the same being always inposition forengagement with the pin or stem 48 as the wheel 35 is revolved.

With a recording device for.computing desired movement of the wheel 36-with the tons of resistance ina train-of cars, such as illustrated herein, there is obviated any complication in the construction "{of the mac ine as the parts are reduced to a mini-. "mum and taken as a whole, very much simgplified. By recording with a wheel such-as 2.35, where the rating does not extend over one thousand tons, the machine may be again simplified bythe. omission of the wheel 36 and the mechanism referred to as cotiper ating with the wheel 35 foractuating' the said wheel 361 f The casing l is'provid'ed' with a cover '51, hinged at 52 and adapted to be locked at 53. The-same may be swung backward to expose to view the operative parts of the apparatus and give access thereto. There is also providcdin the cover 51, a sight open ing 54 suitably located above the tonnage recording wheels to enable the operator to note the number of tons asrecorded bysuch tonnage wheels; and 55 denotes a sight opening which is also arranged in tllG-COVGI 51 and is to enable the operator to note the number of cars in the train asrecorded by the tallying device, all of'whicli, it is betion, what claim and desire te-secure by Letters Patent of the United States, is:
