Appli-cation filed March 4, 1916. Serial'No. 82,264. l

To all 'whom t conce/Mi:

Ee known that I, BERT E. CLoUsii, a citizen of the 'United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certa-in new :ind useful improvements in Mechanically Operated Horse Power Computing vl'echiiies.y of which the following is a specification.

hij invention relates to improvements in apparatus for ascertaining or computing the horse power of a prime mover or inotor, and preferably also for indicating the speed at which the horse power is'determined. Y

fin important object of the invention is to provide a machine of the above inentioncd character. embodying wholly ineclianical means for computing the horse pewer from the ascertained speed and torque.

A. further object of the invention is to provide a. machine of the above mentioned character, which is highly convenient in use, and reliable in operation.

)ther objects and advantages of the in vention will be apparent during the course of the following description. v

Fi G is a bottom plan view of lever mechto actuate the movable parts of the gage mechanism,

Fig. 7 is a plan view of the same, and,

Fig. S is a side elevation of a crank and associated elements. y

ln the drawings, wherein for the purpose of illustration is shown a preferred embodiment of mfr' invention. the numeral 10 designates a main shaft having areduced cylindrical portion 11, upon-whichv f' :is rotatably mounted a sleeve l2, The shaft` 10 has' shoulders 13, formingl with the inner.'

end of the sleeve 12 a cavity for the reception ofV bearing balls i4, as shown. Rigidly connected with the outer endof the shaft 10 is a disk 15, adapted tobe clamped or otherwise connected with the rotatable ineinber'of the prime mover to be tested. rRigidly connected with the outcr'end'of the sleeve 12'is a similar disk i(gto be clamped` or rig! idly connected with of the load.

the rotatable'member` The sleeve 12 is 'provided with aflan'gey 17, provided upon its .periphery with a groove. or-` race-'wayl 13 receiving bearing balls 19. These bearing balls also project into an annular groove or race-wayl 20, formed in` a flange 21.' The flange 21 is preferably formed' integral with an annular housing or casing 22. The lower end of the housing or casing is equipped with a weight or weights 23,tendingto hold the same sta-V tionary in a vertical position. Rigidly connect'edwith the flange 17 is an inner hous-A ing 24. y j

' The relative turning Ainoveinentof the shaft V10 with respect tothe sleeve 12in avr clockwise direction is opposed by a torque' coil spring 25, one` end of whichfis attached or anchored in a l'ring 26,'rigidly attached to thelange 17.- Theother end of 'the' spring 25 is attached or anchored within a ring 27, which is keyed o'rotherwise rigidly attached tothe shaft'10.

Bolted or'otherwise' rigidly attached to the ring 27 for yrotation therewith is a ring-- gear 28, shown more clearly inFigs. 3 vand 4. This ring-gear engages pinions or gears 29, carried by shafts 30. These shafts have their opposite ends rotatably mounted with in openings formed in a flange 31' and lugs 32. The shafts 30 have their intermediate inner shifting ring, having screw-threaded openings 36, receiving a screw-threaded portion 33 of the shafts 30. The inner shifting ring 35 isV provided "upon itsjperiphery with an annular groove or race-way 37, receiving bearing balls 38, also vopera'tingig' within an inner annular groove or'race-way39, formed' in an outer co-acting'shifting ring 4Q. From the foregoing description it is obvious that.' when thejshaft :10 turns with relation to the sleeve-12,[the ring-gear 28 will turn-the' screw-threaded shafts 30 upon their aXe's,-"'V

which will in turn inoveth'eA co-aetin'g shi-fb ing ringsl 35 and 40 to the right. The inner shitting ring not only shifted to the right but must rotate with the shafts 30 and the housing 24, Whilel the outer co-acting ring 40 is nonrotatable but is free to shift laterally. The rotation of the outer shifting ring 40 is prevented by the use of one or more guide studs or rods 41, rigidly attached to the flange 21. The guide rod 41 operates through an apertured head 42, termed integral upon the upper end of the outer shitting ring 40, as clearly shown in Fig. 1. The head 42, as shovvn in Fig. 1, carries a laterally extending crank 43, as shown.

Centritugally operated means for operating the gage mechanism, comprises a centrifugal Wheel or member 44, (Figs. 2 and 4) which is eccentricallv pivoted upon the flange 17 and has a large opening for the reception of the sleeve 12 and has a Weight 45. ris clearly shown in Fig. 4, the Wheel 44 is rotatably mounted upon a stud or trunnion 46, preferably cast integral With the flange 17. Surrounding this stud 46 is a torque coil spring 47, one end of which is attached toa ring 48 rigidly attached to the Wheel 44, rllhe outer end of the spring 47 is attached to a ring 49 clamped or otherwise rigidly secured to the stud 46. It is thus apparent that the spring 47 Will oppose the clockwise rotation of the Wheel or member 44, due to centrifugal action. rlhe centrifugal Wheel or member 44 is in the form of al gear Wheel having gear teeth to engage gears or pinions 50, as shown more clearly in Figs. 2 and 3. rllhese gears are rigidly mounted upon the shafts 51, journaled through openings in the flanges 17 and 31, as shown. rlChek shafts 51 have intermediate enlarged screw-threaded portions 52, as shown. The screw-threaded portions 42 operate vvithin screw-threaded openings 53, formed in an inner shifting ring 54. rlhis inner shitting ring is provided With an outer groove or race-Way receiving, bearing balls 56, also operating within an annular groove or race-Way 57, formed in a coacting outer shitting ring 58. This outer shifting ring is provided with an apertured head 59 sliding upon the guide rod or .stud 41, as more clearly shown in Fig. 3. rlhe head 59 carries a laterally extending crank 60, as shown.

From the foregoing description, it is obvious that when the centrifugally operated Wheel or member 44turns upon its pivot, such turning movement ivill be imparted to theV gears or pinions 50, which rotate the shafts 51. lhey rotation ol the shafts 51, through themediumof their screvv-threaded portionsv 5.2, cause the rings. 54 and 58 to movelatera'lly, the ring 54 revolving While thering. `58fis.non-r'otatable The ring 58 is thus 4shifted tothe right. v

.upon the ring 58.

As clearly shown in Fig. 5, the numeral ('31 designates a speed indicating hand or po' -ter, adaptedto cooperate 'with a speed indicating scale The ninneral G3 nates a horse poner hand or pointer coperating with a scale (34, indicating horse power. The hand or pointer (33 receives its rotati n 'from a pinion 65, engaged by a quadrant G6, (Figs. 3 and 7') which is turned by a slotted crank liis slotted c il; receives a sivoted member 53, ope Within a slotted rlllie pivot ineinber (58 also operates in guide slot 63, as shown. This slotted slide hasY its outer end pivotally connected with a linl-i 70, having pivotal. connection vii'h a stud 71, which is carried `by the cran 3 of the shitting ring 40, as shown in sig. 1. its more clearly shown in Fig. (i, the slide GS) has its end bent over and is pivote-d at 72 Ywith a lever This lever 73 has 'otal connection between its ends with a leer 74, pivoted to a plate or base 75, as shown.. Vlhe lever 73 is piv-v oted at its end with a lever 7G, pivoted to the plate or base 7 Pivotally mounted upon the base 75, as shown at 77, is a bell cranl; lever 7S. L@ne arm or this bell crank lever is pivotally connected with a link 7 i), by means ot' a pivot memlfzeii' 80, operating Within a slot 81, 'lhe linli; 7 is pivotally connected with the free end oy the lever 73 and the slide G9 at the point 7 2. I'Ehe upper end of the pivot element 89 extends upwardly beyond the base 7 5 and is pivotally connected thereabove with a link 81. This linlr 31 has pivotal connection with a crank 82, connected With a quadrant 83 engaging a pinion 84, which turns the pointer 61. larticular attention is called to the fact that the slots 63 and 31 are arranged at substantially a right angle. lllicn the lever 73 is swung to a position so that the pivot 7 2 co incides With the pivot 68, the movement of the slide G9 Will impart no movement to the rand 63. llllhen the lever 73 is moved in the opposite direction, the eKtent of move ment that the slide 69 Will more the pivot 63, correspondingly increases. The free end of the lever 78 has a pivot element 78, secured to the crank G0 of the head 59, formed llt is thus apparent that the pivot 63 will move the horse power indicating hand or pointer in accoroance with the combined movement ot the torque and speed shifting rings.

The operation is as follows:

rlhe Wheel 15 is clamped or other-Wise rigidly attached to the rotatable member of a prime mover or motor while the Wheel 1G is clamped to the rotatable member oli' the load. Upon starting the prime mover to be tested. there is very little, if any, load. the speed builds up, the centrifugal Wheel 44 turns upon its pivot 46, turning the pinions 50, The rotation et these pinions turns the sline (59,

shafts 51, causing the rings 54 and S'to move inwardly. The inward movement of the ring- 5S is transmitted to the bell crank lever 7S through the medium of the crank 6() and associated elements. This movement ofthe bell crank .lever swings the speed pointer or hand 6l to the left along the scale v62, thusindicating the speed at which the prime mover is'operated. As the .load is applied, the shaft l0 turns with relation to the sleeve l2.` This turning movement is transmitted to 'the gear 28, whichy engages and drives the gears 29. The rotation of the gears 29 is imparted to the shafts 30, and the screw-threaded portions of these shafts shift the ring 35 inwardly toward the flange 3l. This movement of the `ring 35 affects a corresponding movement ofthe ring 40. The inward movement of the ring 40 transmitted to its crank 43.. The crank 43 swings the slide 69 upon its pivot 72, andthe position of this pivot is determined by the position of the bell crank lever 78. The lateral inwardy movement ofthe slide 69 is imparted to the pivot `element 68 oil'ierating in the slot 68. rihis pivot element has connection with the crank '67, which turns the toothed segment 66, in turn operating the pointer 68. The pointer is thus made to travel to the right inproXimity to the scale 64, for indicating the horse power of the prime mover. f 1 j It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
