To asZZ whom it may concern.-

Be it known that LGARRETT MARTLING V'RooMn, a citizen of the United States, and a resident of Castle'tonCorners, in the county of Richmond and State-ofNew York, have invented certain new and usefullmprove.

ments in Combination Power-Machines, of

which'the following is a specification.

My invention is an improvement in combination power machines, and consists inv certain novel constructions and combinations of arts hereinafter described and claimed.

mentof my invention. Fig. 2-is'a central side view showing a modified form. Figs 4 is a front view of Fig.3.. I Fig. 5-is a view of a inodifiedform of mechanism for connectingthe weight and driving-shaft. other modification-of. the connection between the weight and thedriving-shaft. I Fig. 7 is a, front view of a modifiedform of mechanism for connecting the floatto the transmission--- shaft. Fig. 8 is a front View. of another modification, and Fig. 9 is a side view'of the Fig. 10 shows another modification of my invention. Fig. 11 is a. side view thereof, and Figs. 12-, l3yand Mare detail views of parts shown in Flgs. 4 and 5. I

In the embodiment shown in Figs. 1 and 2 the mechanism is supported within and above a pit A,-of-masonry.or,other suitable material,- communicating with the water of the ocean through the conduits a, whereby the water in the pit may be influenced by thetide. Slideways a, comprising a plate provided with a cured to the si es of the pit, and floats a are arranged within the pit tobe acted upon by the tidewater-, the sand floats being provided with brackets a at the ends thereof for engaging the slideways, the brackets having grooves for receiving the tongues, whereby to guide the floats in their rising-and-falling movement. Vertical guideways a are.'sup-. ported in the pit by asuitable framework A, and slidably mounted on the guideways are rack-bars a, the rack-bars being connected at the lower ends to the floats and; engaging pinions a7, 'ournaled upon shafts a sup- 'ported by t e framework A before mentioned. The pinionso mesh with, inions a", secured u on a shaft a f, journa ed n the framewor and upon the shaft u. is slidably.

mounteda sleeve of, havingupon oneofthe I Fig. Sisa Fig. 6 is anrojecting tongue a are s e-.'

wheel a is provided with a projection a,

adapted to be engaged by .propctions a a upon the upper'and lower portions of the rack-bar, the said rojections acting to partially rotate the w eel, whereby to operate the clutch; i

YA brakeis provided for the drum a, comprising a lever c. pivoted upon the frame", I

and r'ovided witha brake-shoe a engaging the rum, the lever, being provided with a.

weightin whereby to make suitable pressure upon the drum.

. The drum a. has wound thereon a rope-a winding at its other end upon a roovedul-' ley, a, loosely journaled upona living-s it a, mounted in the framework A and con- I nected thereto by a paWl-and-ratchet-mecb. The pawl-and-ratchet mechan-.

'anism 03?.

ism u is so arranged that when the rope'is wound upon the drum I the oovedpulley a is. disconnected fro Tl the s aft a. The

pulley 0. is provided with another groove a, and woundwithi-n the groove is a rope'a connected to a weight a movable vertically in the pit. I I I I The motion of the shaft aa'is transmitted. by means of the gear-wheel a with the shaft and meshing with the inion 0 upon a shaft a, journaled intl'le amework from whence it may be. distributed in any suitable" manner. I It will be evident from the description that when the float a is moved upward by the tide the rack-bars a at the commencement of their movement will partiallyrotate the [wheels a, through the engagement oft-he pro ections a on the rack-bar with theme-- ection q 'ripon the wheels, to swing the lever 0 to operate theclutch a a. to connect the shaft a with the drum a;

pulleyu and winds up. the rope (rain the groove 0,, thus elevating the weight 07.. The

pawl-and-ratchet connection .ot the pulley a. with the shaft af permits the movement of the drum without -aifecting the shaft. At high tidexthe. projections 0 engage the pro I The winding of the 'rope'c upon the drum'a rotates the- I the gear-wheel a and the pinion a to the shaft e. and the bevel-gear 6 may shaft a. i

In the modificationshown in Figs. 3 and the weight a is attached to'the lower end of a system of lazy-ton gs B, .working upon a fixed shaft 6 and having secured to the upper end thereof the rack-bar a, meshing with the pinions a7, as before described. It will be understood that the mechanism shown in Figs. 3 and 4 is merely a modification. of the manner of connecting the'float a with the rackbars.

In Fig. 5' the grooved pulley a isdispensed with, and the weight a is connected bya link 6 with a lever C, loosely mounted upon the shaft a and provided with a springpress'ed pawl c, engaging'a ratchet-wheel c rigid with-the shaft a, It will be evident that when the rope a is wound upon the drum a the arm C will be drawn upward, ullino' u the Wei ht (1 the awl d mov- P. n P g P mg idly over the ratchet-teeth. When theweight has reached its highest position and the drum a is released from the shaft a the weight tends to draw downward the arm C. and the pawl c engages the ratchet-wheel thus rotating the shaft a i'the rotation being imparted to the shafta by means of the intermeshing gear-wheels a a In Fig. 6 the weighta is attached to arackbar D. meshing with the gear-wheel d, loosely mounted on the shaft of, the gear being provided with a spring-pressed pawl d, engaging a ratchet-wheel d rigid with the shaft a When the-weight is drawn upward by means of. the rack-bar ,D and the rope a, the gear? wheel d is rotated and the pawl cl slips idly over the teeth of the ratchet-wheel (1 When,

however, the weight commences to descend,

the pawl engages the ratchet, thus rotating the shaft (1 I In Fig. 7 the weight a is connected by the links E E to a yol e e, the yoke being connected by the rope'a with the drum a. The links E E slide through bearings inthe supporting framework A, and the weight is guided in its upward and downward movement by the guideways e". A cross-bar e is secured to the. links E E, and the said crossbar is provided with a pin. e engaging a spiral groove '6 in a vertical shatt e, mounted for rotation in the framework A. The bevelgear a is secured to the upper enl gt the e are is now, however, connected withranged to mesh with a bevel-gear (not shown upon the shaft (1 and connected to the shaft by paWl-and-ratchet mechanism similar to that shown in Fig. 6 in such manner that when the weight moves upward the rotation of the shaft 0" not imparted to the shaft e but when said weight moves downward the pawl-and-ratchet mechanism connects the shaft c" with the shaft o In Figs. 8 and 9 is shown afront and side view of a modification wherein the weight a? is connected to a rack-bar G, slidable in a guideway g,supported in any suitable man ner by the framework A and engaging the .inion g", loosely mounted upon the shaft a.

he shaft (1. has mounted for longitudinal movement thereon, but keyed thereto, a

sleeve g, provided with a clutch-face 9, engaging a clutch-face g upon the pinion g" be fore described. The sliding sleeve is operated by the same operating mechanism shown in Figs. 1 and 2, comprising the lover a -and the link a, connecting said lever to the wheel a, the wheel having a projection 0, engaged by the projections (2 and a before described. The rack-bar G also ongages a gear-wheel g, loosely mounted on the shaft and coimected thereby to pawl-andratchet mechanism. 9 in such manner that when the rack-bar moves uoward the gearwheel g rotates loosely on the shaft a and when said rack-bar moves downward the pawl-and-ratchet mechanism 9 connects the gear-wheel to the shaft. The sh aft (1? is p ro vided with the usual gear-wheel a for transmitting movement, and the pinion 0. is actuated by the rack-bar a, before described.

. In Figs. 10 and 11 is shown a modification wherein the fio'at a, is. connected by a trussbar H with the crank-pin h of a wheel h, se cured to a shaft 72, the wheel h. being grooved to receive a rope if, the rope being secured at the point it to the periphery of the wheel.

The ends of the rope h are connected directly with the rack-bars a, one end of the rope being connected to one rack-bar and the other end to the other rack-bar. The wheel h is so proportioned with respect to the height of the rise of the tide that at high tide the crank-pin will be at about the posi tion shown in Fig. 11, while at low tide it will make a similarang-le with the horizontal diameter of the wheel, but on the lower side of said diameter. It will be evident from the description that when the tide rises the rack-bars secured to the end 71 of the rope 71/ will be elevated while at the falling of the tide the rack-bar secured to the end ll. of the rope h will be elevated. In this manner both the rise and fall of the tide will he utilized.

In Figs. 12, 13, andld is shown in detail a means for guiding the lazy-tongs in the modification shown in Figs. 8 and 4. The pivotrods 5 in this device have their ends forked at b and have journaled in the fork frictioi1- rollers b on aging the sides of the guideways b Other iction-roll'ers b-are journaled directly upon the pivot-rods and. also engage the guideways. This arran ement constrains the pivot-rods of the azy-tongs to -move' in vertical lines and in the same verand said shaft, means whereby the rack-bar. may Operate the clutch to release the drum at the end of its upward movement, a driving- ,sh'aft below said first shaft, a pulley journaledon .the driving-shaft, a pawl-andratchet connection between the pulley andthe drivingeshaft, means connecting the drum and. the pulley for impartin rotary movement thereto, said' awl-an ratchet "connection releasing the s aft during said rotary movement, and a cable winding upon aving the pulle during said movement and an attac ed weight whereby to rotate sai pulleyand driving-shaft in the opposite direction when the drum released.
