EDMOND DE MOULIN AND ULYSSES S. DE MOULIN, OF GREENVILLE, ILLINOIS.

LIFTING-MACHINE.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed January 24, 1907- Slerial No. 353380.

To all whom it may concern:

Be it known that we, EDMOND DE MOULIN and ULYSSES S. DEMoULm, citizens of the United States, residing at Greenville,-in the county'of Bond and State of Illinois, have invented a new and useful Lifting-Machine, of which the following is a specification.

This invention relates to machines for testing the strength of ersons and is more par ticularly designed or initiation and other pur oses.

T 1e object of the invention is to provide a machine ada ted to actually or a parently record the weight which can be lifted by a person and which, when the mechanism has 7 assumed a predetermined position, will operate t0 startle the users With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

-In the accompanying drawings is shown the preferred form of the invention.

In said 'drawings: Figure '1 is a perspective view of the machine inverted and Fig. 2 is a view showing the manner of using the machine.

Referring to the figures by characters of reference, 1 is a casing open at the bottom and having recesses 2 in the lower edges of the sides thereof across which are secured base plates 3. These recesses are adapted to receive a cross strip 4 shown in Fig. 2 which extends laterallybeyond the sides of the ma-' grooves 9 formed within the inner faces of the sides of the casing. Rods 10 project from the end portions of the strip and are slidably mounted in the top of the casing, the outer ends of said rods being provided with grips 11. Resistance springs 12 are interposed between the top of the casing 1 and the strip 8 and are preferably coiled around the rods 10. These springs are adapted to retard the upward movement of the strip 8. Abracket 13 is secured upon the lower face oi the top of the casing 1 and has a forked end It in which is l'nlcrumed a lever 15. Due end of this lever is also forked, as

A spring 18 is connected to one end- 0 the catch and to lever 15 so as .to hold said catch constantly pressed against the adjoining edge of the cross strip 8. A notch 19 is formed within one edge of the catch so that when the cross strip is pulled to a predetermined point the same will become seated within the notch 19. A block 20 is secured within the casing and has a concave end in which is seated a rubber bulb 21 said bulb being held in place by a disk 22 at one end of lever 15. As the movement of the disk toward the block 20 is normally prevented by catch 17 pressing against the adjoining edge ef strip 8 it will be apparent that show at 16, and has a catch 17 pivoted thereiii.

and is conneclt p d by a spring 26 with the bracket 13. 1e end of arm 25 bears upon the out-struck portion 27 of a spring leaf 28 fastened ,in any suitable manner to the top of the-casing. The end ofthis leaf normally extends into the path of a pin 29 .said bulb will not be compressed ordinarily projecting from a lever 29 which is pivoted upon a pin 30 extending from a plate 31. A spring 32 is coiled around the pin 30 and is secured at its ends to plate 31 and lever 29 respectively. A block 33 is secured within the casing 1 and has an opening .54. he center of this opening is in an are described about pin 30.

As has heretofore been intimated the spring 26 is normally under tension but will not move lever 15 toward the top of the easing 1 because the catch 17 bears against the adjoining edge of strip 8. Lever 29 normally rests upon the end of the leaf 2Sso as to be held against movement thereby. \Vhen it is desired to use the apparatus the bulb 21 is removed and filled with water or other fluid after which it is replaced between the block 20 and disk 22 and connected [0 nozzle 24. A blank cartridge is then inserted into the opening 34 so that the cap thereof will be in position to be contacted by the lever 29 when the same is released, said lever aeting as a hammer After the parts have been assembled in this manner the casing is placed with its top uppermost and s1 rip 1 is inserted the Weight lifted. After the strip 8 has been through the openings 2. The applicant is then requested to testhis strength and as shown in Fig. 2 is placed with his feet upon the ends of the strip 4 and told to pull up ward on'the grips 11. This upward pull will cause the springs 12 to be compressed, said springs therefore retarding the movement of t e grips. Worm 6 will be rotated by the strip 8 sliding therealong and therefore the index of the gage 5 will berotated to show raised to a certain point it will register with the notch 19 and the catch 17'will promptly engage the strip 8. As soon as the operator has fully tested his strength in this manner he either releases the grips 11 or lowers them,

gradually. This will cause the stri 8 to press downward on the catch 17 t ereby swinging the lever 15. As a result of this action the bulb 21 will he suddenly compressed between the block 20 and disk 22 fulcrum by sprin and a stream of liquid directed upward through the nozzle 24 and into the face of the operator. Simultaneously with. this operation the leaf 28 is pressed upward by arm 25 so as to release the hammer or lever29 and the same is promptly swung upon its 22 so that its-end will strike the cap of t e cartridge in opening 84 and explode it.

What is claimed is:

1. The combination with a casing, a grip rigidly connected thereto, and a resistance spring designed to be tensioned by the movement of the grip in one direction; of anon tainer within and opening through the easing, a lever mountedwithin the casing, and means operated by the resistance spring when released for actuating the lever to force the contents of the container therefrom.

4. The combination with a casing, a cap holder therein, a spring actuated hammer, a nozzle, and a container therefor opening into the nozzle; of means for holding the hammer against movement, a lever, a grip movably mounted on the casing, a resistance spring for retarding the movement of the casing in one direction, and means operated by the resistance spring upon its release subsequent to the tensioning thereof for actuating the lever to release the hammer and expel the contents of the container.

5. The combination with a casing; of a cross strip movably mounted therein, resistance springs for retarding the movement of the cross strip in one direction, a lever fulcrumed within theorising, a'spring pressed catch mounted upon the lever and normally bearing upon and disposed to engage the cross strip, a cap holder within the casing, a spring controlled hammer for exploding the cap, a depressible spring for locking the hammer against movement, a grip connected to the cross strip and disposed when drawn in one direction to tension the resistance springs and place the strip in engagement with the catch, and means operated by the resistance springs when released of stress forreleasing the hammer.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signa tures in the presence of two witnesses.
