SPECIFICATION forming part of Letters Patent No. 401,736, dated April 23, 1889.

Application filed April 9, 1888. Serial No. 270,023. (No model.)

To @ZZ whom, t 11i/ay concern:

Be it known that I, SETH CURLIN, a citizen of the United States, residing at Union City, in the county of Obion, State ,of Tennessee,

have invented certain new and useful Improvements in Marine Velocipedes, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying' drawings, forming part of 1o this specification. p

In Letters Patent No. 315,743, granted to me April 14, 1885, is set forth certain improved mechanism for propelling pleasure-skiffs or similar boats by means of paddle-wheels or a propeller-wheel operated by hand and foot power within the boat.

My present invention has for its object to improve andwsimplify `the `construction of mechanism set" out in said patent, and to this end it."consistsiin the various novel features of construction hereinafter described, illus-i. trated in, the accompanying drawings, and particularly7 pointed out Ain the claims at` the end of this specification. I wish it distinctly understood, however', that while, for convenience of description, my invention may be designated as a marine velocipede, features of the invention are applicable also to the improvement of mechanism whereby the propulsion of the boat is effected :ifnply through hand-power, and I do not therefore Wish the invention to be understood as restricted to mechanism in which foot-power is necessarily employed. H

Fig. 13 is a viewin vertical longitudinal section through the hull of the boat illustrated in Fig. 12, certainy parts of the 7o mechanism being shown in vertical section.

Fig. 14 is an enlarged detail plan View of the yoke at the inner end of the propellensha'ft. Fig. 15 is a detail side view of the yoke shown in Fig, la.

Adesignates the hull of the skitf or other boat, upon the inner face of the bottom of which arefastened suitable rails or stringers, A', whereon are sustained the operators seats andthe mechanism by which the movement 8o of the paddle-wheels is effected. Upon these rails A' is mounted the main frame, the sides B and B' of which are connected bytie-rods l) and cross-bars b', the bottom of the frame B being adjustably held uponlthe rails A' by 85 means of the set-screws b2, which serve to determine the position of the frame upon the rails.

Within the sides B and l' vof the main frame, near the upper end thereof, and which 9o sides in the drawings, Fig. 1, are made approxin mately in the shape of a goose body, neck, and head, are journaled the trunnions C and C', that project from the upper end of the driving-lever C2, to the lower end of which lever is bolted the yoke c, the opposite end of this yoke being formed in piece with the rods d, the outer ends of which rods are united to a treadle, D. From-this `treadle D extend the suspension-rods D', that are sustained by roo the tie-rod b3, that extends through the forward ends of the sides B and B' of the main frame.

To the upper end of the driving-lever C2 willbe connected the hand-rod E, which serves both as a means of enabling the operator to use his hands in propelling the boat and also as a convenient device for controlling the steering apparatus. rlhis hand-rod E, which is provided at its top with the operating-handle E', adjustably bolted on the rod, is preferably connected with the operating-lever in the following manner-that is to say, the operating-lever is provided at its top with a seat or recess to receive the lower end of the hand-rod E, this hand-rod being formed with an `annular groove, c, near its end, wherein will set the end of the pin 3, which serves to prevent the accidental withdrawal of the hand-rod from its seat.

Upon the hand-rod Eis keyed the bevel .gear-wh eel 4, that engages with a corresponding bevel gear-wheel, 5, formed upon the hub of the steering-wheel F, this wheel being journaled, by preference, upon the trunnion or rock-shaft C' ofthe driving-lever C2. Over this steering-wheel F passes the rudder-rope F', that runs through suitable pulley-blocks, f and f', at the bottom, sides, and stern of the boat, and connects with the bar F3 of the rudder F4.

To the lower part of the driving-lever C2 is connected the front end of the pitinan-rod G, the opposite end of this rod receiving a wristpin, g, that is formed upon the face of a shaftwheel, 7L, which is keyed to the inner end of the section H of the main drive-shaft. The inner end of this main drive-shaft H is journaled within a suitable boss or arbor, b4, formed on the side B of the main frame, while its outer end is journaled in a suitable step or block, (i, attached to the side of the boat.

The drive-shaft is, by preference, formed of two sections, the section ll' having its inner end journaled in the side B' of the main frame and its outer end journaled in a step or block, '7, attached to the side of the boat, the inner end of the section H' of the main shaft being connected with the wrist-pin g by means of a suitable link, h', so that the two sections H and l-l' of the main shaft move in unison. Upon the outer ends of the sections H and H' of the main shaft are keyed the sprocketwheels I, from which extend the drive-chains l', that pass around corresponding` sprocketwheels, K, that are keyed to theinner ends of the shafts of the paddle-wheels L. The shafts which carry the paddle-wh eels L are sustained within the journal-blocks M, the under sides of which, as seen in Figs. l and 3,arc slightly curved and rest upon the correspondinglycurved upper faces of the bracket-plates M', that are bolted, as shown at fm, to the sides of the boat. The journal-blocks M are adjustably held upon the brackets M in' any suitable Ilnanner-as, for example, by flanges S, that retain the blocks ou thebrackets, the position of theblocks being determined by means of the set-screws 9, that pass through threaded holes in these blocks. My purpose in thus sustaining the paddle-wheels within adjustable bearings or blocks is to enable these wheels to be raised or lowered to accommodate the mechanism to boats of different sizes and according as the boat is loaded or light.

Within the boss or arbor b4, formed upon the side B of the main frame, is journaled the upper end of the vertical shaft O, upon which is keyed the fly-wheelO',the lower end of this shaft being preferably provided with an enlarged conical head, o, th at is sustained within a suitable step or block, o', that rests upon the casting 02, the ends or cross -bars bl of which are bolted, as at bs, to the sides B and B' of the main frame. Upon the hub of this fly-wheel 0' is keyed the bevel gear-wheel O2,

. that engages with the bevel-gear h of the shaft-wheel h', keyed to the inner end of the section H of the main drive-shaft. At the top of the sides B and B' of the main frame are formed the rails b5, on which is mounted the operators seat P, from the under side of which project the lugs p, that hold the seat in position upon the top edges, and by means of the set-screws p', that pass through threaded holes in the lugs p, the seat can be readily adjusted to bring the operator into the desired position with respect to the driving-lever.

The operation of my improved mechanism as thus far described will be seen to be as follows: The operator occupying the seat P will place his feet upon the ends of the treadle D and his hands upon the handle E of the hand-lever E. He will thus be enabled by both hand and foot power, or either, to readily operate the driving-lever C2, which in turn will communicate motion through the pitmanrod G tothe-shaft-Wheel 71, and the main driveshaft I-l H', the sprocket-wheels I, and thence through the chains l and sprocket-wheels K and their shafts to the paddle-Wheels L. It will also be seen thatV as motion is thus imparted to the sections ll and H' of the main drive-shaft and to the shaft-wheel L the engagement of this wheel h with the corresponding bevel gear-wheel, O2, on the hub of the fly-wheel O' will cause this Iiy-wheel"to be revolved.

My purpose in providing thei'Iy-wheel O' is to give increased steadiness to the `movement of the paddle wheels and to carry the pitman G over the dead-centers, and as well also to relieve the operator from the necessity of both pushing and pulling in order to keep up the speed of the boat, and l regard this feature of importance, because in propelling the boat it is desirable that the operator should be relieved as much as possible from the necessity of pushing the halidlever from him, since such movement is apt to speedily become tiresome. Th edriVe-wheel O is located, by preference, in horizontal position and near the bottom of the` boa-t, in order that its weight may tend to increase IOO lIO

rather than toY interfere with the steadiness of the boat.

In Fig. l of the drawings the hand-rod E is shown as provided with a supplemental handle, E2, the purpose of which is to enable a second operator, who may occupy the seat P', to assist in working the hand-rod E, and thus aid in propelling the boat. The supplemental seat B is mounted upon the frame P2, the bottom of vwhich is adjustably connected with the stringers A by means of set-screws p2 and feet p3, and the seat Il is held upon the frame P2 by means of the Iianges p4 and set-screws'pi, which enable the position of the seat to be adjusted either backward or forward,or enable it to be reversed. Itis apparent that if the operator occupying the seat I is to assist in working the hand-rod E the seat P will be turned to a position the reverse of that shown in the drawings, Figs. l and 2. If desired, however, the operator occupying this supplemental seat may operate a separate hand-rod, R, the lower `end of which is stepped in the forked casting fr, that enters holes in and is pivotally connected to the cuffs or blocks a, that are adjustably attached by set-screws fr".

The upper end of this rod R is provided with one or more handles, E", and this rod R passes through the link or casting r2, to the yoke-shaped ends of which is attached by a suitable bolt the drive-rod R', that is connected with the yoke c at the bottom of the main drive-lever C2 by means of the bolt 2. The link or casting 'r2 is held on the supplemental hand-rod R by a set-screw, fri, and, if desired, a further supplemental drive-rod, R2, may lead from the hand-rod R to another supplemental hand-rod for anotheroperator near the bow of the boat. It will thus be readily seen that any desired number of operators may assist in the propulsion of the boat, although for ordinary pleasure-boats one or two will usually be sufficient.

In order to effect the steering of the boat, it is only necessary for the operator to turn the handle E and the hand-rod E, as by so doing the bevel gear-wheel 4, by reason of its engagement with the corresponding wheel, 5, will revolve the steering-wheel Fand cause the rope l1", which passes over this wheel, to shift the rod Fit of the rudder, according as the handle E is turned in either direction, It will thus berseen that the mechanism for steering theboat is under t-he const-ant control of the operatonand by mounting the hand-rod E so that it can 'be freely turned I am enabled vto avoid the necessity of using a supplemental sleeve or similar device for con- "trolling the movement of the steering-wheel. By mounting the steering-wheel F in vertical position, as shown, I am enabled to lead the steering-rope directly therefrom to the bottom of the boat,where it will be out of the way. My obj ect in mounting the bevel gearwheei 4 immediately above the trunnons C and C of j the d riving-lever C2 is to hold this wheel, so that as the hand-rod is moved back and forth the corresponding movement of the Wheel 4; will be so slight as to not aifect the steering-wheel F or the rudder.

My purpose in adj ustably mounting the main frame, which sustains the operating mechanism upon. the stringers A', is to enable this frame and such mechanism to be moved either back or forth in order to properly balance the boat; and it is apparent that when any shift in the position is thus made it will only be necessary to correspondingly lengthen or shorten the drive-chains I, which may be of the well-known link-belt type.

My obj ect in sustaining the journals of the paddle-wheels L in adjustable bearings M is to enable these wheels to be raised or lowered to compensate for the variations in height of the sides of the boat to which the operating mechanism may be applied, and to compensate also for the change in the draft of the boat, according as it is loaded or light. The upper faces of the brackets M are preferably curved, as shown, and correspond with an arc drawn from the center of the main dri ve-shaft H Il, so that when the main frame has been set within the boat, and it is simply desired to vary the position of the. journals of the paddle-wheels, they can be moved up or down upon the standards without shifting the position of the main frame.

In Figs. IO and Il of the drawings my invention is shown as applied to a boat having a single paddle-wheel at its stein. In this construction the sides B and B of the main frame, which support the operating mechanism, are connected by tie-rods h and cross-bars b, but are of somewhat different shape .from those hereinbefore described. The precise shape, however, of the main frame I do not regard as important. In the upper ends of these sides B and B is journaled the drivinglever C2 with the adjacent and connected parts, as above described; but in this modification the main drive-shaft II is a single undivided shaft that is journaled in the boss D* upon the side B of the frame and in a bracebar, B3, that is bolted to and extends outwardl y from the side B of the frame, andupon the inner end of this drive-shaft is keyed the shaft-wheel 71 similar to that above described, and in like manner engaging with the bevel-gear O2 of the fly-wheel O.

On the outer end of this drive-shaft II is keyed the sprocket-wheel I, over which passes the sprocket chain or belt I, that leads to a sprocket-wheel, K, upon the end of the journal l of the stern paddle-wheel Il, and in this construction suitable idlers, l-l and l2, held withina standard, 13, bolted to the stern of the boat, are employed to guide the sprocket chain or belt from the main drive-shaft to the shaft of the paddle-wheel. In this modified construction the steering apparatus is the same as that already described. The stern. paddle-wheel L is sustained within the rearwardly-projecti n g beams Il and 15, that may IOO IOS

be provided with asuitable hood, 16, over the top of the paddle-wheel, and the front ends of these beams are by preference connected by hinges 17 to the rear seat or cross-bar, 18so that the outer ends of the beams can be raised or lowered in order to enable the paddle-wheel to be vertically adjusted. This vertical adj ustment of the paddle-wheel is effected by means of the threaded spindles 19, the reduced lower ends of which are stepped ir the brackets 20, that are affixed to the stern of the boat, and these spindles extend through the threaded bars 21, bolted to the under sides of the beams 14 and 15, and have their upper ends provided with suitable hand-wheels, 22, by which they can be readily turned. My purpose in thus adj ustably mounting the beams that sustain the stern paddle-wheel is to enable this wheel to be raised or lowered to compensate for the height of the stern, either when the mechanism is applied thereto or when this may be rendered desirable by the variation of the load of the boat, and it will be readily seen that by turning the spindles 19 by means of the hand-wheels 22 the adjustment of the paddle-wheel L can be easily effected. v

From the foregoing description it will be understood that the rotation of the stern- Wheel L necessary to effect the propulsion of the boat will occur when the drive-lever C2 is operated, the movement of this lever being communicated to the shaft-wheel h through the pitman G, and from this shaft -wheel through the main shaft H, the sprocket-wheel I, and the' chain I and sprocket-wheel K to the paddle-wheel L.

In the modification illustrated in Figs. 12 an d 13 of the drawings my invention is shown as applied to the propulsion of the boat through the medium of a propeller-wheel, L4, and in this construction the drive-lever C2 and-its connections and the steering apparatus are the same as that already described. In this construction, however, the ends of the main drive-shaft H are journaled in the sides B and B of the main frame, and this main drive-shaft is provided with a crank, 25, to which the end of the pitman G is connected. Upon the main vdrive-shaft II is keyed the shaft-Wheel 26, that engages with the pinion 27, keyed upon the shaft 23, the ends of which are journaled in the sides B and B of the main frame, the sides of the main frame in this construction being provided with bosses, through which the ends of the shaft 28 pass. Upon the shaft .28 is also keyed the bevel gear-wheel 29, that en gages with a corresponding bevel gear-Wheel, 30, affixed to the inner end of the propeller-shaft 31. This propellershaft 31 has its inner end journaled within a yoke, 32, the ends of which are sustained upon the bosses, and the position of this yoke can be shifted vertically by means of the threaded spindles 33, that pass through the bars 34 and bear upon the opposite sides of the yoke, the position of these spindles being determined by means of suitable set-nuts, 35. The propeller-shaft 3] by preference extends through a tubular casing, 40, that passes through the stern of the boat, and has its rear end held within the bracket-plate 41, that is bolted to the stern and bottom ofJ the boat. The rear end of the tubular sleeve 40 is provided upon its interior with a screw-thread adapted to receive the corresponding exteriorly-threaded bearing-sleeve 42, through which the propeller-shaft 31 passes, the flange of this bearing-sleeve 42 being, by preference, upon the rear side of the bracket-plate 41 and serving to hold the sleeve 40 in proper position with respect to said plate. The forward end of the tubular sleeve 40 is exteriorly threaded to engage with the corresponding threads upon the interior of a tubular stuffing-box, 44, that is provided with a perforated division-plate, 45, between which and the cap 46, that screws onto the end of the stufng-box 44, will be held suitable packing. By thus sustaining the propeller-shaft within a tubular sleeve, 40, I am enabled to provide a very secure bearing for this shaft and to obtain an effective means for packing the bearings of the shaft and preventing all leakage of water into the boat. y

My purpose in mounting the inner end of the propeller-shaft 31 within the adjustable yoke 32 is to enable the shaft and propellerwheel to be properly set in position upon any boat notwithstanding the variations in the size or draft thereof, and it will be readily seen that if it is desired to change the angle of the propeller-shaft in order to accommodate it for a boat of greater or less draft, this can be readily accomplished by varying the position of the yoke through the medium of the adjusting-bolts, it being understood, however, that a corresponding change in the opening through the stern of the boat will be made.

From the foregoing description it will be seen that when motion is imparted to the driving-lever C2 by the operator in the manner hereinbefore described the shaft-wheel 26, through the medium of the cog-wheel 27, shaft 2S, and bevel- gears 29 and 30, will cause the rotation of the propeller-shaft and wheel necessary to effect the propulsion of the boat. Upon the propeller-shaft 31 is mounted a flywheel, 50, correspondng with the fly-wheel O', in the construction hereinbefore described, and serving the same purpose.
