To all whom it may concern:

Be it known that I, ALBERT C. ALBERTSON, I

a citizen of the United States, and a resident of the city, county, and State of New York,

have invented certain Improvements in Power Transmitting Devices, of which the following is a specification.

This. invention relates to certain improvements in power transmitting devices, and has for its object to provide a device of this general character of a simple and comparatively inexpensive nature, and of a novel and 1mproved construction wherein the centrifugal 'orce generated 1n revolvlng'or rotating bodies is employed in the transmission of power,

the construction and arrangement of the parts being such that the said centrifugal force is communicated through certain-mechanical instrumentalities to attain an im- 0 proved and useful result in the transmission improved power transmitting device, whereby certain important advantages are attaine'd, and the device is rendered simpler, less expensive, and otherwise better ada ted and more convenient for use, all as wi 1 be The novel features of the invention. will be carefull defined in the claims.

In the accompanying drawin s which serve to illustrate my invention-Figure 1 is a plan view showing one embodiment of the improved powertransmitting device; Fig. 2 is a side elevation of the device, as shown in Fig. 1 Fig. 3 is a sectional view taken vertica ly through the device in the plane indicated by line a,a in Fig. 1, and showing certain features of construction to be hereinafter described; Fig. 4 is an enlarged sectional detail view taken in the plane indicated by the line l b in Fig. v3;'Fi 5 is a sectional detail viewsomewhat simi ar to Fi 4, but

taken in the plane indicated by the dine cc in Fig. 3; Fig, 6 is a partial sectional view illustrating a modified formation of the im roved power transmitting device, andig. 7 is a fragmentary detail view showing certain features of construction of the device as illustrated in Fig. 6.

Referring first to Figs. 1 to 5, 1 represents a frame having spaced bearing'pieces 2, 2, in .5 which is journaled a shaft 3, having a tgrooved sheave or pulley 4, securedupon it etween l the said bearin pieces, and in position to receive one end 0 a band or belt 5, by means of which the said sheave or pulley 4 andthe shaft 3 whereon the same is secured, are driven from any suitable source ofpower (not shown). lhe extremities of the shaft 3 are provided, beyond the bearing pieces 2, 2, with crank arms 6, 6, which are extended in opposite directions, respectively, from said shaft, and are provided, at their outer ends, with wrist-pins 7, 7, which are engaged in slotted guide-ways 8, 8, produced in rods 9, 9, held to turn, at their inner ends, upon pins or studs 10, 10, extended from slide blocksv 11, 11, mounted for sliding reciprocatory movement in horizontal directionsin guideways 12, 12, produced in frame members 18, 18, erected at opposite ends of shaft 3.

The outer ends of the rods 9, 9, are pro-- vided with weights 9, 9 and the arrange ment of the parts as above described is such that the movement of the shait 3 is commu nicated by reason of the connection of its crank arms 6, 6, to the rods 9, 9, in such mannor as to cause the same to turn. upon the pins 10, 10, as centers, and as the speed of movement of said rods 9, 9, increases, the centrifugal force generated thereby is per-- mitted to throw the slide blocks 11, 11, in op posite directions along the respective guide wrist pins 7 of the said crank arms 6, 6, are engaged, permitting movement of the said rods 9, 9, in unison. with the slide blocks 11, and in the direction of their guide ways 12, independently of the said crank arms 6, 6. By this arrangement of the parts, as the speed of rotatory movement of the rods 9, 9, increases, the centrifugal force is caused to act with increased power upon the rods 9, 9, and causes the slide blocks 11, .11, with which the said rods are connected to reciprocate along the guidesvays 12, 12, in the frame members 18, 18, in opposite directions to each other.

Upon the frame members 18, 18, outside of the guide ways 12, 12, wherein the slide blocks 11 play, are arranged bearing pieces 17, 17, wherein are pivoted, as shown at 16, 16, rods or levers 15, 15, the inner endsof which have rounded enlargements 14, 14s, loosely engaged in sockets in the outer sides of the said slide blocks 11, whereby it will be seen that the reciprocatory movement of the slideblocks 11 is imparted to the rods or leways 12, 12, the slots 8, 8, wherewiti'i the i vers 15, in such a manner as to reciprocate the same pivotally upon their pivotal connections with the bearing pieces 17. Upon the levers are mounted collars 19, '19, of which there are two for each lever, one such collar being at each side of the pivotal connection of said le er with the corresponding bearing piece 17, and 20, 20, represent links connecting said collars with pawl arms 21, .21, mounted to oscillate upon'shafts 24, 24, whereon are carried ratchet Wheels 23, 23, the teeth of which are engaged by pawls 22, 22, carried by the said pawl arms 21, 21, in a well known way. By this arrangen'ient the oscillatory movement of the rods or levers 15, 15, is communicated through the links and pawls 22' to the ratchet wheels 23, 23 in such a way as to impart intermittent rotatory movement to the shafts 2 1, 24, and since the throwof the pawls 22 over the erimeters of the ratchet wheels 23, 23 wil vary, with the speed of rotatory movement of the rods 9, 9, and will gradually increase as the throw of the slide blocks 11 increases upon the rise of the centrifugal force'incident to increased speed of rotation of the said rods 9, 9, it will be seen that the speed'at which the shafts 24 24 are turned by the mechanism will also'be'commensurate with the speed of movement of the arts and with the increase of centrifugal orce generated by the rotation of the rods 9, 9.

From the above description of. my improvements, it will be seen that the power transmitting device constructed according to my invention is of an extremely simple and comparatively inexpensive construction, and is particularly Well adapted for use by reason of the effective operation attained by the utilization of the centrifugal force, Which insures actuation of the driven devices in unison with the increase of speed of the rods or members 9, and it will also be obvious from the above description that the device is susceptible of considerable modifica-' tion without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts of the device as herein set forth in carrying out my invention in practice. For example, in some cases, the slide blocks 11,11, may be dispensed with, and as shown in Figs. 6 and 7, the guide-ways 12 may be replaced by elliptical guide-ways 25, in which the inner ends of the levers 15 15 are extended and adapted to travel as shown at 26 in Figs. 6 and 7, the said inner ends 26 of the levers carrying rollers or sleeves 27 for rolling contact upon said elliptical guide-ways and having at their inner extremities loose connection with the inner ends of the rods or members 9, 9, as clearly shown at 28. By this arrangement a great portion of the impact and shock produced by the striking of the slide 1 block 11 upon the ends of its guide way when 1 the device is being operated at high speed is avoided and a more even and uniform and E economical operation of the improved power l transmitting device is attained.

Having thus described my invention, what ing a frame having parallel spaced guides 4 arranged opposite to each other, parts mounted for reciprocatory movement along the respective guides, weighted members each having one end mounted to turn on one of the respective reciprocatory parts, and a rotatory. part arranged to turn between the spaced guides and having oppositely arranged crank portionsslidably connected with the respective weighted members.

3. A power transmitting'device comprising a plurality of, oppositely arrangedfmembers adapted for independent movement under centrifugal force, a rotatory part between saidjmembers having oppositely directed cranks each of which has sliding connection with one of said first-named members to compel turning movement thereof, parts connected for movement in unison with therespective members, and guides wherein thesaid parts are engaged for reciprocatory movement.

4. A power transmitting device comprising a plurality of oppositely arranged members adapted for independent movement under centrifugal force, a shaft journaled between said members and parallel with the axis of rotation thereof, a pulley on said shaft, oppositely directed crank arms on said shaft having sliding connection with the first named members 'to compel turning movement thereof, parts connected for move- 2. A power transmitting device comprisi 2 1 and guide-ways wherein the said parts are engaged for reciprocatory movement.

5. A power transmitting device comprising parallel spaced guide-ways, slide-blocks mounted for reciprocatory movement in the respective guide-ways, members pivotally connected at their inner ends with the respective slide blocks and having their outer ends extended outwardly therefrom in 0pposite directions respectively and provided with weights, a shaft mounted to turn between the guide-ways and provided with driving mechanism, and oppositely directed crank arms carried at opposite ends of said shaft and having at then outer ends sliding connection with said pivoted members to ment in unison with the respective members, 7

lmving at aheir outer ends sliding connection 5 with. said pivoted members to compel turning movement; thereof in unison with said shaft, and pivobally mounted; levers connested for movement in unison with the respective slicle blocks.

In Witness whereof l have hereunto signed. my name this 28th day of J any 1908, in the presence of two subscribing witnesses.
