WATER-SKATE.

Specification of Letters Patent.

Patented June 22, 1920.

Appncationkied october 2, 191e. serial No. 328,040.

To all whom it may concern: a

Be it known that I, GUsrAv citizen of no country, and a resident of the borough of Brooklyn, county of Kings, city` and State of New York, have invented certain new and useful Improvements in Water- Skates, of which the following is a specification.

This invention relates to improvements in devices by means of which a person may skate or glide upon the surface of a body of water. i

The invention has for its principal objects the provision of means controlled by the movement of the feet of the operator for propelling the sustaining means over the surface of the water, and to provide propelling means adjustable to permit backward movement when desired. f

There are other important yobjects and advantages of the invention, all of which will hereinafter appear.

In the accompanying drawings, Figure 1 is a plan view of the device;` 1

and 4 showing another modified construction of the device;`and Figs. 10 and 11 detail views showing a modified form of impeller blade reversing means.

l Referring to the various parts by numerals, 1 and 2 designate a pair of long and narrow floats or buoyant hollow sustaining devices, preferably pointed at their ends as shown. Each float is provided midway its ends with a foot plate or rest 3 and also with a hand-rail 4 supported on a pairfofA standards 5. A bar 6 extends longitudinally between the floats 1 and 2 above the waterline and is supported at its forward end by means of a vertically extending rod 7 rigidly HAnBow, a j

held at its lower end to said bar and provided vvith an integral cross-bar at its upper end having central spacing portions 8 and reduced end portions 9 yto which the upper ends of plates or supporting arms 10 are pivotally held. The pair of plates or swinging supporting arms 10 are pivotally' held at their lower ends at 11 Vto the floats 1 and 2 adjacent ythe forward ends of the floats. y

A pair of oppositely disposed vertical posts or standards 12 arel rigidly held at their `lower ends to the floats 1 and 2 adjacent the rear ends of said floats and a pair of upwardly extending arms 13 are hinged at their lowerends at 14 to the upper ends of the posts 12. Suitable braces 15 may be provided for assisting in supporting posts 12.

The arms 13 are pivotally held attheir upper ends to the reduced end portions 16 of a cross-bar having a central enlarged spacing portionl 17. The cross-bar is formed integrally with or rigidly held to the upper end of a vertical rod or standard 18 which is rigidly secured at its lower end to the rear end of the bar 6. A pair of pulleys 19 are journaled on vertical pivots in suitable supports 2O at the front and rear ends of bar 6. A pair of cables 21 pass over pulleys 19 and are securedat their ends to a pair of slides 22 held to guides 23 on the floats vto move freely in an up and down direction. The pairs of arms 10 and 13 are normally held in vertical positions and the floats normally maintained directly opposite each other by a f flat spring 24, secured at one end tothe cross-bar 17 and at its other end to a pin 25 on one of the arms 13, `and a similar flat spring 26 held at one end to cross-bar 9 and at its other end to a pin 27 on one of the arms 10. Y

An impelling device` is rigidly but adjustably heldto each of the arms 13 to rock in unison with said arms. Each impeller comprises a bar 28, preferably rectangular in cross section, the upper end of which extends through a rectangular aperture in a bracket 29 held to arm 13, and an impeller blade 31 pivotallyv held tothe lower end of the bar by a bolt^32. The bars 28 are held in their adjusted positions by suitable set screws 30, and it will be obvious that the extent that bladesrl will dip into the water may beregulated by adjusting bars 28 vertically. An impeller reversing device is provided for each of the impellers. Each reversing device comprises a lever 33 pivotally held intermediate its ends at 37 to bar 28 and provided with a'pair of spaced stop lugs 34 and 35 at its lower eud located at opposite sides of the impeller blade 3l., A latch lever 36 pivotally held at one end to the upper end of lever is provided with a pair of' spaced notches 58 and 39 adapted to co'perate with a pin 40 on bar 28 to lock the reversing lever 33 in either of its two adjusted positions.

lfVhen lcversl are adjusted so that stops 34 will arrest the swinging movement ofthe p blades lwhen the blades reach positions substantially parallel with bars 2S, the skater may move forwardly over the water by pushing' first one float and then the other forwardly. Il levers are adjusted so that stops will arrest the swinging movement of the blades when the blades reach positions parallel with bars 28, `the skater may move backwardly by pushing first one float and then ,the other rearwardly. The device maybe steered by means of a rudder 4l'held to a rotatable post 42 at the rear end of the float l. An arm 43 held to the rudder post 42 is connected by a cable 44 with a rock Aarm 45 on a vertical rock shaft 46 journaled in suitable bearings held to one of the standards 5 and provided with an operating handle 47 preferably so located as to .form practically a continuation of the adj acent hand-rail 4.

In the modified construction shown in Fig. 7, the various parts are constructed and arranged as above described, except for the fact that one of the cables 48, corresponding with the cables 21, extends forwardly and the other rearwardly from the pulleys 19 and said cables are connected at their ends with the floats adjacent the forward and rear ends of the floats by slides 49 and guides 50 similar to slides 22 and guides 23. Referring to the construction shown in `Figs. S and 9, the bar 6 is connected at its ends by pairs of links 5l and 52 to pairs of rigid standards?) and 54 mounted on the floats. The impeller-blade carrying bars 28 are adjustably held by set screws 55 in brackets 56 formed on the lower ends of levers 57 pivotally held on studs 58 on the standards 54. The levers 57 are provided with elongated slots 59 through which pins 60 on the links 52 extend for vibrating the impellers.

In Figs. l0 and 1l a modified construction of impeller blade reversing means is shown.

This arrangement comprises a pair of stop bars 6l and 62 pivotally held to the opposite ends of a pair of levers 63 and 64. The levers 63 and 64 are pivotally held intermediate their ends to the impeller blade supporting bar 28 and the lever 63 is formed with an extension or handle to permit either 'each float adjacent opposite ends of the float,

four links pivotally connected -at their upper ends `to the upper ends ol' the standards and pivotally connected together in pairs at their lower ends, a bar extending longitudinally of the floats and supported by the pivotal connections between the lower ends of the pairs of links, two impeller-blade carriers pivotally held intermediatetheir ends to standards adjacent the same endof differ- -ent floats, means forming a pin and slot connection between the upper end ot each earrier and the link connected with the standard supporting the carrier, and impeller blades mounted on the lower ends of the carriers.
