DOUBLE COMPOUND POWER-APPLYING MACHINE.

To all whom it may concern:

Be it known that we, J OSEPH A. BOZUNG, formerly a citizen of Germany, but who has declaredhis intention of becoming a citizen of the United States of America, and PAT- mo S. MOMAHON, a citizen of the United States of America, both residing at the city and county of Denver and State of Colo rado, have invented a newand useful Double Compound Power-Applying Machine, of

" which the following is a specification.

Our invention relates to improvements in double compound power applying machines. The object of the invention is to provide a machine or device of this character in which power is applied to a pawl and nected to ratchet mechanism through a series of levers acting one upon another in progressive order, the initial power exerted uponthe first lever ofv the series being transmitted through the succeeding levers :to the pawl and ratchet mechanism, said mechanism being arranged to rotate a power shaft from which power may be transmitted throughj a system of gearing and "applied in any desired manner. I

Further, to provide a power machine ofthis character inwhich the initial power maybe manually. applied to the first lever of the series, or thesaid lever may be conpower driven operating mecha- IllSIIl.

These objects. are accomplished by the mechanismiillustrated in the accompanying drawings injwhich: I

Figure 1 is a side elevation of the machine looking toward the initial operatinglever.

Fig. 2 is a side view at right angles to Fig. 1 and looking toward the second lever of the series. I

Fig. 3 is a plan view of the machine. 9 Fig. 4 is an enlarged sectional view on the line 4-4 of Fig. 3, illustrating the pawl passed rigidly secure the plate to a fixed V Specification of Le'tterslatent.

support The plateis provided with posts or standards which may, if desired, be secured thereto, but which preferably form an integral part of the plate. The standards,

on a fulcrum pin 11, in the upper end of; the

standard 3, which is bifurcated 'to receive the said lever, and the ratio of thedistance between the fulcrum and weightend of the.

lever, to the distance between the fulcrum and "the power end thereof, may be determined by the use for which the machine is employed. y y 1 In the drawing, the long end o'f the lever is shown as being less than three times the length "of the short end, or of a ratio to the short end of less than three to one; but the fulcrum, in any case, will be positioned to meet power requirements. Thislever may be manually operated, if desired, but, in the drawings, it isshown'as power 'driven,jand is connected with a sourceof powerin'the following manner: 1 i v a V The power end offth'e lever 10, is provided with a longitudinal slot 12, through which passes awrist pin 13, in the outer end of a crank 14, which is rigidly secured upon one end of a shaft 15, which is mount ed in bearings on .the standards 9. I

Th'e shaft 15, carries .a pulley 16, whic is connected by a belt 17, with a suitable power source (not shown), by which the shaft 15, is rotated, and an oscillating movement is thereby imparted to the'lever, the pin 13,-slidin'g from one end of the slot 12, totheother asthe crank 14, ro-

wrist tates. V e a. c The weight end of thelever 10, is connected "by a link 18, with th'epower end of a second lever 19, which, is pivotally mounted on a fulcrum pin 20, infthe upper end of the standard 4, which is bifurcated to receive the said lever 19;

For, convenience and compactness, the

lever 19, is arranged to-lie at right angles,

to the lever 10, and as shown, the distance between its fulcrum and weight end bears the same proportion to the rest of the lever, as the corresponding parts .of the lever 10, bear to each other, but with this lever, as with the lever 10, the fulcrum may be at any desired point between its ends.

The ends of" the levers .10 and 19, which are connected by the link 18, are formed with elongated holes 21, and 22, respectively, to receive the pins 23 and 2 1, respectively, which connect the ends of the levers with the link, and as the link is limited to a verticalmovement, while, at the same time, the ends of the levers travel in arcs, it is apparent. that the link would be bent or broken by the levers, but for the elongated holes 21, and 22, which allow sliding movement of the ends of the levers on the pins 23 and 2 1, as will be seen by reference to Figs. 1, and'2. i

The link 18, is of the form shownin Fig. 6, and comprises a central body portion and bifurcated end portions which are apertured, as shown, to receive the pins 23 and 2 1, the bifurcations being arranged at right angles to each other.

The links hereinafter mentioned, are of the. same construction as the link, 18,. and therefore need no description, and in all cases the levers arexprovided with elongated holes to receive the link pins. i The weight end of the lever 19, is connected to the power end of a lever 25, by a link 26, and this lever is mounted on a fulcrum pin 27, in the upper end of the:

pends from the free or weightend of said lever, while the; other is located between the fulcrum and the power end thereof, and the same distance from the fulcrum as the other link. I

The links 28, are connected at their lower ends, to' the free ends of a'pair of levers 29, the opposite endsfof which are bifurcated and are loosely mounted on a power shaft 30, which is mounted in hearings on the upper ends of the standards 6. lVithin the bifurcated end of each lever 29, and rigidly mounted on the shaft 30, is a group of ratchet wheels 31, each group comprising, preferably, four ratchet wheels. Each of these wheels is provided on each side with a slight circular projection 32, and

these; projections serve to space the. tooth,

portions of the wheels, as vvillbe understood by reference to Fig. 5. These wheels are keyed upon the shaft in such relation to one another that the teethof the second wheel in each group, are slightly out of line with those of the first wheel; the teeth of the third wheel, are slightly out of line with those of the second wheel, and the teethof the fourth wheel, are slightly out pawls of each group are held in engagement with the ratchet teeth, by a platejspring 35, which is screwed to the lever. 29, as shown, the forward end of each plate being slitted to form four independent fingers 36, which rest upon, and hold the pawls against the ratchet teeth, as clearly shown in Figs. 4,

and 5.

Power fromthe shaft 30, is transmitted the following manner: I V a A gear wheel 37, is rigidly mounted on the said shaft '30, and this gear wheel meshes with a gear wheel 38, of suitable diameter, which is rigidly secured upon a shaft 39,

which is mounted in hearings on the upperends of the standards 7. The shaft39, has

also securedthereon a bevel vgear 40, of.

greater diameter than the gear 38, and the bevel gear meshes with a gear-41, of suitable diameter, on a shaft 42, which. may be connected in any desired. manner with an; 0b-' ject, whereby the power imparted to the power shaft 30,. is transmitted throughthe shaft 42, to the said object, to exert a drawing or a:lifting force, or toproduce an oscillating: or a reciprocating movement as the case may be; the manner of transmittingpower, from the shaft 12, beingdetermine by the character of work to beperformed.

In practice, power is applied to the power,

end of the initial lever 10, either manually,

or through the mediuinof the crank 14, and

its power-driven shaft 15, and this power is transmitted to the lever-.19,-a nd thence to the lever 25, the meclianical advantage due 'to each succeeding lever,'being in proportionto the position of the fulcrum of'each lever with respect to its opposite ends. The rock ing movementof the. lever 25, imparts an oscillatingmovement-to the. levers 29, by which the groups, of ratchet wheels, are alternately engaged, and theshaft 30, is thereby continuously rotated. By arranging the ratchet wheels in the manner before mentioned, there can be no lost motion; of the pawls 34, with respect to the ratchet teeth, as one pawl in each group is always in engagement with a tooth.

Having described our invention, whatwe' levers having bifurcated ends, which ends are pivotally mounted on said shaft, each bifurcated end inclosing one group of ratchet wheels, pins extending through said bifurcated ends, pawls mounted on said pins and adapted to engage said ratchet wheels, the teeth of each wheel in each group being out of line with those of the next succeeding wheel, an oscillating lever, links connecting the same on each side of its fulcrum, with the free ends of the bifurcated lever, and means for oscillating said lever.

2. In a machine of the character described, a power shaft, two groups of ratchet wheels rigidly mounted on said shaft, the teeth of each wheel in each group being out of line with those of the next succeeding wheel, a pair of levers having bifurcated ends, which ends are pivotally mounted on said shaft,

each bifurcated end inclosing' one group .of ratchet wheels,-pins extending through said bifurcated ends, pawls pivotally mounted on said pins in line with the ratchet wheels and adapted to engage the same, plates secured to said bifurcated levers, having independent integral spring fingers which engage said pawls, an oscillatory lever, links connecting the same on said side of its fulcrum, with the free ends of the bifurcated levers, and means for oscillating said lever.

In testimony whereof we afiix our signatures in presence of two witnesses.
