LOCOMOTOR Filed April 4. 1931 2 Sheets-Sheet 2 In/venters Patented July 26, 1932 UNITED STATES PATENT oFFlicE LEE M. PARRISH AND` FLOYD G. KELBSCH, OF REDFIELD, SOUTH BAKOTA` LOCOMOTOR Application led April 4, 1931.

This invention relates to a locomotor, and it is primarily an object of the invention to provide a motor of this kind which is adapted to travel below a field of ice.

j Another object of the invention is to provide a motor of this kind for conveying under ice a Stringer or rope for the placing of nets or seines for long distances or other uses of like nature.

A further object of the invention is to provide a device of this kind of a buoyant character and which is provided with means for contact from below with a. field of ice to facilitate its tra-vel and which is also prol vided with means visible through the ice to facilitate the location of the motor.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved locomotor whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of our invention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accomso panying drawings, wherein Figure 1 is a view partly in section and partly in elevation illustrating a locomotor constructed in accordance with an embodinient of our invention and in position below a field of ice;

Figure 2 is a view in top plan of the structure as illustrated in Figure 1;

Figure 3 is a detailed view partly in section and partly in top plan illustrating a form of switch which may beemployed in connection with the device.

As disclosed in the accompanying drawings, H denotes a hulk of torpedo shape and the walls of which being preferably made of f sheet iron. The interior of the hulk is airtight although access therein may be had upon removal of the hatches 1 and 2 in the upper wall, the hatch 1 being substantially midship while the hatch 2, as herein dis i@ closed, is at the stern.

Serial No. 527,828.

Extending from the stern of the hulk H is a shaft 3 carrying a conventional propeller 4, the inner end portion of the shaft 3 being suitably coupled, as at 5, withl the drive shaft 6 of an electrical motor M. Desired access to the motor M and its associated parts may be readily had upon removal of the hatch 2.

The circuit a for the motor is in electrical connection with the batteries B placed within the hulk H and which can be readily applied or taken out upon removal of the hatch 1.

One of the legs of the circuit a has interposed therein a switch mechanism of a conventional type including the stationary contacts 7 and a swinging or rocking Contact 8. As herein disclosed, the stationary contacts 7 are carried by a table 9 supported above the motor M while the rocking or swinging contact 8 is carried by the lower end portion of a vertically disposed shaft 10. This shaft 10 extends up through the top wall or deck of the hulk H through a suitable packing gland 11. The upper or extended end portion of the shaft 10 carries a cross arm 12 to the opposite endrportions of which are secured flexible members 14. These members 1a4 extend rearwardly of the device and are directed through a rearwardly disposed `guide tube 15 carried by an outboard frame 16 supported by and disposed rearwardly from the stern of the hulk H. These flexible members 14 are of desired length and provide means whereby a person above the field of ice may readily swing lthe Contact member 8 to open or close the circuit a to the motor M as required and particularly when the motor is in working position below the ice field.

The frame 16 also provides a mounting for the rudder 17. This rudder may be of any style or type desired as its particular construction and manner of operation forms no part of the present invention. It may be stated that it is preferred that the rudder be of a well known automa-tic type which will keep the motor traveling in a stra-ight course as set by the user.

Disposed above the upper wall or deck of the hulk H and supported thereby by the delill pending members 18 are the elongated parallel runners 19 substantially straight from end to end and which extend from points adjacent the bow of the hulk to points immediately adjacent to the stern of the hulk. These runners 19 are also positioned slightly outboard of the hulk H along the sides thereof and are positioned entirely above the hulk so that the runners 19 will have unhindered or unobstructed Contact from below with an ice field F.

The top wall or deck of the hulk H in the bow thereof is provided with a lamp 2O the illuminating unit 21 of which in the present disclosure being interposed within the circuit a for the motor M although this lamp may7 if desired, have a separate circuit. The lamp 20 throws its light rays or beam upwardly thus providing means visible through the ice field to enable a ready location of the motor therebeneath. It is believed to be obvious that the hulk H possesses suli'icient buoyancy when in use to maintain the runners 19 in requisite Contact from below with the ice field F, thus assuring the desired travel of the motor to enable the conveying of` a Stringer, rope or the like beneath the ice field and more particularly for the placing of nets or seines for long distances in wintertime fishing.

The flexible members 14 are of sufficient length to enable the user to stop or start the locomotor as desired.

From the foregoing description it is thought to be obvious that a locomotor constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.

A locomotor for use under an ice field comprising a buoyant body, propelling means therefor, and means projecting upwardly and laterally beyond the width of the body for contact from below with the ice field for maintaining the body on an even keel, said means extending fore and aft of the body.

In testimony whereof we hereunto affix our signatures.

LEE M. PARRISH. FLOYD Gr. KELBSCH.
