Patented Nov. 14, 1916.

Application led'May 27, 1916. Serial No. 100,268.

To all whom it may concern:

Be it known that l, J AN BJnLIs, a subject of the King of Hungary, residing at East Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Collision-Preventers, of which the following is a specification.

This invention relates to new and useful improvements in collision preventers.

The primary obj ect of the invention is the provision of an attachment for boats whereby the motive power thereof will lbe automatically reversed in the event that the vessel approaches sufficiently near to any object to engage the projecting portion of the device therewith.

A further obj ect of the invention is to provide a bow carried fender upon a boat, any violent contacting of which automatically reverses the boat propelling means whereby the boat is reversed in its direction of travel preventing injurious collisions.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this application and in which like designating 'characters refer to corresponding parts throughout the several views: Figure 1 1s a side elevation of a Jforward portion of a vessel provided with the present device, the engine and its controlling means being illustrated by dotted lines. Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged side elevational view of the device, parts being broken away, and Fig. 4l is a lonvitudinal sectional view taken upon line 11F-IV of Fig. 3.

The present device is herein illustrated in connection with a boat 10 having a propelling engine or motor 11 'positioned therein, the` vertically arranged mast said boat having a 13 at the bow portion 12 upon the deck thereof.

A bracket 14 is secured to the prow 15 of the boat at a point adjacent the deck 13 and is provided with forwardly extending tubular shock absorber cylinders 16 pivoted to the said bracket as at 17 and containing buffeting coil springs 18 bearing against pistons 19 arranged within the said cylinders and provided with rods 20 pivotally connected to said pistons. j

Upright rectangular frames 21 provided with parallel vertical pickets 223in the form of fence sections are secured together at their forward edges in angular arrangement having their upper rear corners connected together by a brace 23. The piston rod 20 of the upper shock absorber is connected at its forward end to the brace 23 and also within the forward angular portion 24 of the frames 21, while the piston rod 20 of the lower shock absorber extends forwardly and is attached as at 25 to the angular connecting point at the bottom o-f the frames 21. The said lower shock absorber piston rod 20 is obliquely arranged while oblique struts 26 connect the said lower piston rod 20 with the lower rear corners of the frames 21.

A trip bar 27 extends inwardly of the boat 10 through the prow thereof as at 28 having its inner free end 29 slightly spaced from a reversing lever 30 of the motor 11 whereby upon an inward longitudinal shifting of the bar 27 the end 29 thereof engages the lever 30 for reversing the said motor thereby causing the boat 10 to stop its forlward travel and be propelled rearwardly.

The forward end of the bar 27 is secured to a lower brace 31 connecting the lower rear corners of the frames 21, the bar 27 extending transversely of the said brace 31 and secured to the lower forward meeting corners of the frames 21 at the aforementioned point 25 thereof. v

.From this detailed description of the device, at once apparent, it being understood that during the forward movement of the boat 10, the forwardly positioned buii'er formed by the frames 21 and pickets 22 will come in contact with any object in advance of the boat, which contact will be only slightly felt by the boat 10, the shock thereof being partially absorbed by the shock absorber springs 18. The rearward movement of the frames 21 longitudinally slides the bar 27 rearwardly eecting a reversal of the motor 11 as heretofore described producing a backing movement of the boat`10, thus preventing any collision object positioned forwardly thereof. .Guy

klines 32 connect the forward and rear cor- 21 with a point adjacent 12 as at 33 while a horiners of the frames the top of the mast the complete operation thereof will be' between the boat 10 and any l v zontal stay rope 34: may be provided for the said mast if found desirable.

While the form of the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction without departing from the spirit and scope of the invention as hereinafter claimed. Y

What I claim as new is r- In an automatic reversing device for ships, the combination with a ships engines reversing lever, of operating means for said reversing lever comprising a bracket attached to a ships bow, a pair of forwardly- .extending cylinders pivoted at their rear Copesof this patent may be obtained for ve cents each, byraddressing the Commissioner of Patents, Washington, D. C.
