Application filed March 15, 1915. Serial No. 14,607.

, invented certain new and useful Improvements in Canoe Motor-Frames; and I do hereby declare that the following is a full,

clear, and exact description of the invention,

In the drawings: Figure 1 is a perspective side view of the frame in operative'position; F 1g. 2 is the same raised; Flg. 3 1s a'stern view of' a canoe \vlth the frame applied, in

lowered position; Fig. 4: is a-detail of thesprlng suspension means for the outer frame;

and Fig. 5 is a section on line 5-5 of Fig. 1 looking in the direction of the arrows.

The main objects of the invention are, to provide efficient, durable, easily. attached, and easily constructed means for attaching motors to canoes and the like, such means being so arranged as to permit lifting of the motor in case it strikes an obstruction or enters shallow water, so as to prevent any possible damage to the canoe or the motor. Also, this supporting means can be so lifted as to entirely raise the propeller out of the water, when desired. I

Further objects are, to provide means for supporting the weight of the motor independently of the "canoe, and to provide means for preventing vibration from the motor and and for preventing possible injury to the canoe when the motor drops into its original position, after raising; being an improvement on my United States Patent Number 1,118,208, dated November 24, 1914.

Referringto the drawings in detail, the inner frame is -composed of side beams 1 connected at their inner ends by a cross iece 2 and at their outer ends by a bench 3.

his frame is secured to the canoe 1 by means of a cross bar 4; located beneath the piece 2, with its ends extending beneath the gunwalcs of the canoe, and securely bolted to the piece 2. By tightening the bolts connecting cross piece 2 and bar 4, these mem-. bers may be made to grip the gunwales tightly, so as to firmly secure the inner frame at its inner end. Bench 3 is provided, on its under face, with blocks 5 arranged in V shape to fit the contour of the sides of the canoe. These blocks fit the sides of the canoe snugly and serve to prevent any lateral or forward movement of the inner frame.

The outer frame is composed of two side beams 6 considerably longer than beams 1 of the inner frame and extending somewhat beyond the stern of the canoe, and braced by a bench 7. Near the outer end of the outer frame a suitablybraced motor attachi'ng block 8 is-mounted, at a slight outward angle, and adapted to receive the motor, of any suitable construction, which is attached thereto by the usual screw clamp or similar means. The inner ends of beams 6 are pivotally connected to the inner ends of beams 1 of the inner frame, soas to form a vertical swinging or hinged" joint. The beams and bench of the outer frame are so placed as to fit snugly over this inner frame, when the outer frame isin its normal lowered position, as in Fig. 2. By this means, the outer frame is securely braced and is normally held in a horizontal position, so that the propeller and rudder. are properly immersed in the water a slight distance'in back of the canoe. In case the propeller strikes an ohstacle, or the canoe runs into shallow water, the outer end of theouter frame will rise so as to permit the motor to rise, thus pre-' venting any possible damage to the canoe or the motor.

. To overcome the tendency of the motor to depress the stern of the canoe, due to its weight, air chambers or flues 9 are secured to each of the beams 6, of the outer frame, by means of suitable arms 10 and brackets 11. vThese air chambers are so placed as to rest on the surface of the water, when the motor is lowered into operative position, so

as to support its weight, and are pointed at their front ends so as to offer a minimum of resistance to the water. Also, they are, each, provided with a screw cap 12 to permit of their being tested to insure their being air tight.

Special means are provided to prevent vi bration from the motor, or possible injury to the canoe when the motor is forced out of the water by an obstruction and drops back into its original position. Headed pins 13 are slidably mounted through the 'top of bench 3 through the inner frames. These pins are held raised, as in Fig. 4, by coil springs mounted thereon, beneath the bench, and having their upper ends secured to the under face thereof and their lower ends secured to the lower ends of the pins. By this arrangement, when the outer frame is lowered, bench 7 thereof rests on the heads of pins 13 and puts springs 14 under tension, which thus act as a spring supporting means for the outer frame and absorb all shocks and vibration.

F or the purpose of lifting the outer frame, for repairs or the like, a hand screw 15 is threaded through a nut 16 secured on the under face of bench 7, and provided on its lower end with a head 17 pivotally connected thereto. This head 17 rests on plate 18 secured at the center of the upper face of bench 3. By operating screw 15 the outer frames can be raised or lowered, as desired. As there is no conne tion between head 17 and plate 18 this arrangement does not in anyway interfere with the ordinary opera tion of the frame. The frames are braced by suitablestrips and angle irons. and prcvided with suitable eyes through which are passed the lanyards for operating the rubher. The frame has been shown as applied .to a. canoe having inside gunwales only.

In the case of a canoe having outside gunwales certain obvious changes in the details of the attaching means will have to be made, and I wish to include all such changes in this application wherein a preferred form only is disclosed.

It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention without in any way departing fromthe field and scope of the same, and it is meant to include all such within this application wherein only a prean outer frame pivotally connected at its inner end to the inner end of the innerframe, spring supporting means therefor,- and moto' attaching means carried by the said outer frame.
