APPARATUS FOR BURNING IN BEARINGS OF INTERNAL-COMBUSTION MOTORS.

Application filed September 14,1822. Serial No. 588,240.

1 czZZ whom-it may com-era.

Be it known-that I, WILLIAM B. NIEN KIRK, a citizen of the United States, residing at Maquoketa, in the county of Jackson and State of Iowa, have invented new and useful Improvements in Apparatus for Burning in Bearings of Internal-Combustion Motors, of which the following is a service after having been repaired or overhauled.

It is also my purpose to improve'and' Sim+ plify the general construction of the appa ratus of the class described and to provide an apparatus whereby the crank shaftof the 7 internal combustion" engine and its asso-' ciated parts will be operated at the proper speed to facilitate the wearing in of such D rt-s." i

Wi'th theabove recited objects in view and others of similar nature, the invention resides in the construction, combination and arrangement of parts hereinafter setkforth in and falling within the scope of the appeded claims.

In the accompanying drawings Figure 1 1s a view in side elevation of my apparatus the same belng shown as connected to the crankshaft of an internal combustion motor.

Figure 2 is a top view of the'same.

Figure 3 is a vertical sectional view on the line 33 of Figure 1.

Figure 4 is a like view on the line 44 of Figure 1.

Figures 5 and 6 are views of details of the invention.

-Referring now to the drawings in

detail

1, 1 designate substantially A-shaped frames respectively, each comprising legs 2, 2- and across bar 3 and cross bars 4, and 5 respectively arranged above the cross bar 3 and in the same vertical plane as the latter. These

frames

1, 1 are spaced apart in parallelism and are connected together by means of horizontalbrace bars 6, and crossed brace bars? arranged at the opposite sides of the frames and connected to the legs thereof as clearly shown in Figures 1 and ,2

belt pulley 12 by means of which .tate the latter.

'22 carried. by the crank shaft In the present instance I have shown in F i of the drawings. The lower ends of the legs 2 are formed of outstanding feet 8 that are 'bolted or otherwise connected to an appropriate foundation.

The cross bars 3,4 and 5 on one frame lie respectively in the same horizontal plane as the cross barson theother frame and journaled in the alining cross bars 3, 4 and 5 are horizontal shafts 9, 10 and 11, respectively.

The lower shaft 9 carries upon one end a power may be transmitted to theshaft 9 in order to ro- The other end'of the shaft 9 is equipped with a pinion 13 that meshes with a gear 14 fixed upon the shaft 10. Also fixed upon the shaft 10 adjacent to the gear 14 is a pinion 15 that meshes with a gear 16 fixed upon the shaft 11. In the present embodiment of my invention the

gears

13 and 14 arein the ratio l to 4 while the pinion15 and gear 16 are in a like ratio thereby stepping down the speed of the shaft 11.

One end ofthe shaft 11 is preferably squared in cross section as at 17 and pro-- 'jectsbeyond the bearing carried by the cross bar 5 and slidabl'y mounted upon the squared end 17 of the shaft '11 is a sleeve 18. "The outer end of the sleeve 18 is connected by means of a universal joint 19 with one end of a short shaft 20 and the other end of a" shortshaftQO is formed withta clutch collar 21 that is adapted to engage the cross pin ofthe motor.

ure 00f thedrawings the fan belt pulle v 28thatis on the forward end of the crank shaft of Ford motors whi'eh is illustrated in Figure 1 of the drawings. i

In practice the belt pulley 12 is connected -with a suitable source of power and motion transmitted to the shaft 9, pinion 13 and gear 14 to the shaft 10 and from the shaft 10 to the shaft 11 through the pinion 15 and gear 16. However, before power is applied to the belt pulley the motor run in is arranged adjacent to the squared end of the shaft .11 and the shaft 20 connected to the crank shaft of such motor, the universal joint 19 and the sleeve 18 permitting the shaft 11 to be connected to the crank shaft of the motor easily and quickly and irrespective of the distance between the motor and the shaft 11 within certain limits.

the'belt pulley the shaft 11 permits the mo- The power being applied to' and relative arrangement of parts inasmuch .as in the future practice of the invention various changes andmodi cation may be made such as fallwithin the scope of the invention asdefined in my appended claims. ,IIaving described my invention. what I claim and desire to secure by Letters-Patent, is 1- 1. In-apparatus of the class described, the 1 combination with A-shaped frames spaced apart in parallelism and each including legs and across bar and cross bars arranged above and in the same vertical plane the first-mentioned cross bar, the cross bars of ,one frame being ,in the same horizontal planes as those of the other frame, shafts jonrnaled in said 'alining cross bars respectively, means for transmitting; power to the lowermost shaft, a step down gearingbetween the lowermost shaft and the next adgacent shaft and a. step down gearing he-' tween the last-mentioned shaft and the top shaft and means whereby said top shaft may be connect-ed to the crank shaft of an inter-,

nal combustion motor substantially as and for the purpose described.

2. In apparatus of the. class described, the combination [with I l-shaped frames spaced apart in parallelism and each ineluding, legs and a cross bar and cross bars arranged above and in the same vertical plane as the first-mentioned cross bar, the cross bars of one frame being in the same horizontal planes as those of y the other frame, shafts journaled in said alini ng cross bars respectively, means for transmitting power to the lowermost shaft, :1 step down gearing between the lowermost shaft and the next adjacent shaft and a step down gearing between the last-mentioned shaft and the top shaft, and adjustable means whereby said top shaft may be connected to the crank shaft of an internal combustion motor.

3. In apparatus of the class described, the

combination with ,A-sha-p'ed frames spaced apart in parallelism and each including legs and a cross bar and cross bars arranged above and in the same vertical plane as the first-named cross bar, the cross bars of one frame being in the same horizontal planes as those ofthe other frame, shafts jonrnaled in said alining cross bars respectively, means for transmitting power to the lowermost shaft, a step down gearing between the lowermost shaft and the next adjacent shaft and a step down gearing between the lastinentioned shaft and the top shaft, and adjustable means whereby said top shaft may be connected. to the crank shaft of an internal combustion motor, said adjustable means comprising a sleeve shdab'lv connected to said top shaft and designed to rotate therewith, a short shaft in line with said sleeve. and designed to connect to the crank shaft of the motor at an universal oint between said short shaft id sleeve.

In testimony whereof I affix mv signature.
