' Specification of Letters Patent.

Patented June 4, 1912.

Application filed September 5, 1911. Serial No. 647,737.

To all whom it may concern Be 1t known that we, EDWARD B. DESEN- nnne and EDWARD S. PILSWORTH, a 'clt-lzen "of the United States and a subject of the Kingdom of Great Britain, respectively, re-

siding at Kalamazoo, Michigan, and at Battle Creek, Michigan, respectively, have invented certain new and useful Improvements. in Propellers, of which the following is a specification.

ThlS invention relates to lmprovements in propellers.

The main objects of this invention are First, to provide an improved-propeller adapted for use in shallow water and in water filled with water plants, logs, or other debris. Second, to provide an improved propeller having these advantages which is also adapted for use as a steering means. Third, to provide an improved propeller having the advantages above enumerated,"

which is strong and durable in structure and not likely to be damaged in use and one I which is easily manipulated. I

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by'the'device's and-meansdescribed in the following specification.

The invention is clearly defined and pointed out in the'claims.

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail vertical longitudinal section of a fiat bottomed boat shown in 0on ventional form, having our improved propeller applied thereto, the propeller being shown in full lines in one position and in dotted lines in a raised position. Fig. II is a detail view partially in horizontal section taken on a line corresponding to line 22 of Fig. I. Fig. III is a detail view partially in vertical section taken on a line corresponding to line 3-3 of Fig. I. Fig. IV

is a detail view partially in vertical section, taken on a line corresponding to line 4-4 of Fig. I. Fig. V is a detail plan view, showing the tiller ropes 20 connected to the steering post arm 19. I v

In the drawing, similar reference characters refer to similar parts throughout the several views,and the sectional views are taken looking in the direction of the little arrows at the'ends of the section lines.

' Referring; to the drawing, the boat 1 is of the flat ottom type upon which our improved propeller is especially designed for use, that is, a boathaving a shallow draft and adapted for use in shallow water. 'The engine 2 which is shown in conventional form, is mounted at the rear end of the boat. The propeller shaft is formed of sect-ions 3 and 4, the section 3 being the crank shaft or engine shaft and is supported in suitable bearings to project through the rear end of the boat. The propeller 5 is mounted on the rear end of the section 4. The shaft sections.3 and 4 are connected by a universal joint, comprising the fork members 6 and 7 connected by the journal pin block 8 and the journal pins 9 and 10. The joint member 7 is provided with a socket 11 for the end 12 of the propeller section 4, thus providing a slip joint connectionfor the section 4 to the universal joint.

The steering post 13 is provided with a :The ring 14 is provided with journals 15 wh1ch are disposed horizontally and in alinement with the horizontal axial center of-the shaft joint. The post is supported in a sleeve16,the sleeve being provided with a flange 17.engaging the underside ofthe boat and with a clamping nut 18 on its upper end. On the upper end of the post is a rearwardly projecting arm 19 to which the tiller ropes 20 are connected.

Under the propeller, we arrange a flat shoe 21 which is provided with forwardly projecting arms 22 mounted on the journals 15 on the sides of the member 14 of the. steering post; I Y

The bearing 23 for the rear end of the shaft section 4 is supported by a bracket having arms 25 thereon, the arms being secured to the sides of the hearing by means of the screws 26. The bearing is connected by the links 27 to the journals 15 on the annular steering post member 14.

A chain 28 is provided by which the ropeller-may be adjustably suspended rom the arm 19. The lower end of the chain of the bolt 30 which may be engaged with any desired link thereof. v

To assist in supporting the steering post, we provide an arm 30 which pro ects through the rear end of the boat beneath the annular member 14 of the post and is secured thereto by the pivot 31.

With the parts thus arranged, the propeller rides over weeds and the like which are kept from fouling the propeller by means of the shoe 21 and the shoe also rides over the logs or other debris, serving as a guard for the propeller, and in shallow water it rides on the bottom preventing the propeller from en aging with the bottom. The pro eller can be easily swung to either side so t at it serves as a steering means.

We have'illustrated and described our improved propeller in detail in the form in which we have embodied the same. We are aware, however, that considerable variation in structural details are possible without departing from our invention. lVe have not attempted to illustrate such modifications as they will undoubtedly be-readily understood by those skilled in the art to which this invention relates.

Having thus described our invention, what we claim as new and desire to secure'by Letters Patent is:
