LEWIS A. DOUGHERTY, OF ELKHART, INDIANA.

MARINE MOTOR.

Specification of Letters Patent.

Patented Jan. 4, 1916.

Application filed June 20, 1914. Serial No. 846,335.

To all 001mm if m (13 concern Be it known that I, LEWIS A. Douonnn'ry, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Marine Motors, of which the following is a specification.

This invention relates to improvements in marine motors.

The main objects of this invention are: First. to provide an improved marine motor adapted as an attachment for row boats, sail Second, to provlde an improved marine motor whlch 1s readily-atboats and the like.

tached to a row boat, sail boat or the like, and which is adjustable to swing the propeller out of the water or to inoperative position and also to permit the propeller to pass obstructions. Third, to provide an improved structure having these advantages which is comparatively simple and durable in structure and convenient to use.

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

I accomplish the objects of my invention by the devices and means described in the following specification.

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

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

Figure I is a detail side elevation of my improved marine motor attached to a boat, the boat being partially in longitudinal sections to better show the arrangement of parts, the arm 19 being indicated in its collapsed position by dotted lines.- Fig. 11 is a detail view with the motor supported in its inoperative position, the boat being shown in longitudinal section. Fig. III'is a detail horizontal section on a line corre-- spending to the broken line 33 of Fig. I. Fig. IV is an enlarged detail partially in vertical section on a line corresponding to line 4-f of Fig. III. Fig. Vis an enlarged detail section on a line corresponding to line 55 of Fig. 1, showing details of the mount-= ing for the engine in the supporting basket. Fig. VI is a sectional view of the propeller support taken on a line corresponding to line 6-6 of Fig. II. Fig. VII is an enlarged detail view of the tiller lock taken on a line corresponding to line 7-7 of Fig. VIII.-

Fig. VIII is a detail transverse section showing details of the tiller lock taken on a line corresponding to line 8-8 of Fig. I. Fig. IXas a detail perspective view of a modified form of tiller lock. Fig..X is a detail sect1on of a modified form" of engine supportmg ournals. Fig. XI is a detail side View of the link 28.

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

Referring to the drawing, Fig. I is a side View of a boat to which my improved motor I mechanism is secured as by means of the bracket 2, which is provided with a clamping screw 3 arranged through an arm 4 on the brackets The bracketis provided with a pair of upwardly projecting arms 5 havin bushing-like bearings 6 for the journals of the cylinder 8. The journals are integral wlth the arms 9 projecting laterally from the sides of the cvlinder 8. These arms are so disposed that the journals proper 7 are alined with the horizontal center of the cylinder. The crank case 12 is bolted to.the outer end of the cylinder as is well-known practice.

The journals 7 are tapered and the bearmgs 6 are tapered to receive them so that the parts can be nicely adjusted. The arms 5 of the brackets are split and the bushinglike bearings are threaded therein for adjustment, clamping bolts 13 being provided for claimping the bearings in their adjusted positions.

The crank shaft 14 has a fly wheel 15 on,

shoe 21which extends below and to the rear of the propeller 20. On the upper end of the housing 19 is a sleeve 22, the sleeve being split at 23 and provided with a clamping screw 24 by means of which the sleeve .is

clamped upon the housing so as to turn ment of the sleeve independent of the 001- I lar. On the lower end of the supporting bracket or frame are rearwardly projecting arms 27, the arms being curved or segmental in form. A support comprlsing a pair of links 28 being pivoted to the collar 26 at 30', while the link 29 is pivoted to the adjustable slide member 31 on the arms 27 by thescrews 32 which also secure the slide member, in its adjusted positions. The links are pivotally connected to each other by the pivot The links are preferaby channel-shaped in cross section so one closes into the other as 'shown in Fig. III. Friction springs 34 a re interposed between the links for applying frlction thereto so that the motor is relieved from shock as it is thrown to its inoperative position or as it swings to permit the propeller to pass over an obstructlon or returns to its operative position. The link 29 1s provided with a pin 35 which coaots wlth a segment shaped notch 36 on the link 28 which prevents the links collapsing when extended. The pivot 33 of the links when extended swings past a plane extending through the pivots 30 and 32 so that the links constitute a toggle lock and thelinks do not tend to collapse and the propeller is supported in its raised position. A chain 37 is connected to the links for breaking the toggle. The clamp member 31 is slidable upon the arm 27 so that adjustment may be had at this point. For locking the propeller in its vertical position I provide a catch 38 which is bifurcated and pivoted on the collar 22 at the points 39 and the arms of which are adapted'to engage the screws 32. The hand lever 40 is pivoted at 41- in convenient position to be reached by. the operator, The lever is connected by the link; 41 to the catch. See Fig. I. clamped upon the sleeve 22, has a section 43 pivoted at 45 and provided with a hand piece 44 so that the oscillating movement of the motor on its supporting journals does.

not interfere with the operation of the tiller. The rudder 46 is carried by the rod 47, the lower end of which is supported by the shoe 21 and the upper end ofv which is secured by the sleeve 48 to the arm 49 projecting from the rear end of the tiller. The arm 49 is connected to the tiller by the bolt 50 and to the sleeve 48 by the clamp 51 provided with a clamping bolt 52. The sleeve is clamped to the upper end of the rod 47 by the clamping bolt 53. This permits of the removal of the rudder and when removed The tiller 42, which is messes 1 the arm 49 isswungdown against the sleeve 22, as shown by dotted lines in Fig. 1, in which position it does not interfere with the normal operation of the motor, the propeller itself being used as the steering means. If it is desired to use only the rudder as a steering means the clamp 51 .is loosened so that it serves as a bearing and cables, not shown, are attached to the cross arm 61 on'the sleeve 48. I preferably, however, use the rudder as an addition to the propeller steering means. 1 i

28 and 29 is provided, the hnk It is sometimes desirzible to lock the tiller in a central position and to accomplish this I provide the tiller withajlock 54 which is secured in its adjusted position by means of the set screw 56 arranged ina longitudinal slot 57 in the tiller 42 to secure the lock in its adjusted position, see FigQjVIli. The

lock is adapted to engage the notch-like keeper 58 in the cylinder flan'e,xsee VII. stop pm 59 assists in: ooatimg'v the lock in its engaging and disengaging posiions.

When it is desired to adjust the lock 54 the set screw 56 Is loosene'dand the lock 'pushed longitudinally to or from engaging journals 10 are screwed into the arms 9 instead of being integral therewith as shown in the detail in Fig. V and the bearings 6 are secured in their adjusted position by the lock nuts .6?

.In the modification shown in Fig. TX, I provide a simple screw 60' for locking the tiller in a fixed position.

With the parts arranged as I have illustrated and described the motor may be quickly attached to or removed from a boat, such as a row boat or a sailboat. When using in shallow water or water in which there are logs or other debris the catch 38 is disengaged-so as to allow the propeller to swing as its shoe passesover an object. The friction springs prevent shocks as the motor swings, on its journals. When desired, the propeller maybeswung out of the water and is automatically locked in its elevated position by means of the support described. The joint of the support is broken to release the same by a pull on the chain 37. The rudder is also convenient to operate and the combined action of the propeller andrudder are secured. t v

.5 I have not attempted to maintain the proper proportions of the parts in the accompanying. drawing as they are only intended to be illustrative.
