BOAT CARRIER Filed May 28, 1951 2 Sheets-Sheet 2 Henry F. Proe/r/ INVENTOR.

Attorneys Patented Feb. 2, 1954 UNITED STATES PATENT OFFICE 6 Claims.

The present invention relates to improvements in boat carriers, and more particularly to a boat carrier which is of extensible form, whereby boats of varying lengths can be carried thereby, and wherein means is provided on the boat carrier for raising and lowering the boat relative thereto. The application is a continuation-in-part of my copending application, Serial No. 139,143, filed January 8, 1958, now abandoned.

An object of the present invention is to provide a boat carrier comprised of a frame supported on wheels, the longitudinal bars of the frame being of extensible form whereby the frame can be made to assume various lengths for accommodating various size boats.

Another object of the present invention "esides in the provision of means for supporting a boat within the frame, the means for supporting the stern of the boat including a strap resiliently carried by the hanger member of the frame which is disposed at the rear of the boat carrier.

A still further object of the present invention resides in the provision of winch means with means for efiecting winding of the same, the cable being windable on the winch means and disposed over pulleys whereby the free ends of the cable can be secured to a boat when it is desired to raise the boat into the boat carrier for positioning the stern of the boat over the strap.

Various other objects and advantages will become apparent from the detailed description to follow. The best form in which I have contemplated applying my invention is clearly illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the entire boat carrier of the present invention;

Figure 2 is a side elevational view of the boat carrier shown attached to the rear of a vehicle and with a boat supported within the boat carrier;

Figure 3 is a top plan view of the boat carrier;

Figure 4 is a vertical transverse sectional view taken substantially along the plane of line 6-4 of Figure 3;

Figure 5 is a horizontal sectional view taken substantially along the plane of line of Figure 4;

Figure 6 is a vertical sectional view taken substantially along the plane of line 6-6 of Figure 3;

Figure 7 is a vertical transverse sectional view taken substantially along the plane of line 1-: of Figure 6;

Figure 8 is a vertical longitudinal sectional view taken substantially on the plane of line 8-8 of Figure 1; and

Figure 9 is a detail perspective view of a modifled rear wheel arrangement for the trailer.

Referring more particularly to the drawings, wherein like numerals designate like parts throughout, the numeral It! designates generally the boat carrier of the present invention which is comprised of a frame having a center bar l2, a substantially U-shaped lower bar H, a vertical bar it provided by an extension of the center bar l2 which is angulated downwardly for connection to the bight portion of the U- shaped lower bar l4, and a substantially U- shaped hanger member designated generally by the numeral I8 for interconnecting the rear ends of the longitudinally extending bars of the frame.

Looking now at Figure 1, it will be seen that the center bar I2 is angulated at 2% to provide the vertically extending bar it. A, pair of brace struts 22 and 2d are fixedly secured to the vertex of the angularly extending bars [2 and I8 and have their free ends fixedly secured to opposing portions of the bar 14 for rigidifying the forward end of the frame. The lower end of the vertical bar i5 is provided with a forwardly extending bracket 25 having an aperture 28 formed therein whereby the boat carrier can be secured to a towing vehicle, such as the vehicle 30 provided with the towing bracket 32, as seen best in Figure 2.

The frame of the boat carrier is further provided with a bow supporting strut 34 which interconnects forward intermediate portions of the substantially U-shaped lower bar it, a central portion of the strut 35 having a dip 33 formed therein for engagement with the keel of the boat.

The hanger member it of the frame is of substantially U-shaped form and has a horizontally disposed bar 33 connected to vertically disposed bars 4% and 2 by means of the elbows M and 43. The lower portions of the bars 49 and 42 have T- fittings 48 and 58 secured thereto to the rear ends of the legs of the U-shaped bar M. A pair of wheels 52 and 54, of conventional form, are secured to the lower ends of the Gil and t2 for supporting the rear end of the boat carrier frame. Rigidifying struts and 53 are fixedly secured to the underside of the lower bar leg portions with their free ends connected to the fork-like wheel supporting elements B and Gil.

Central portions of the longitudinally extending bars I2 and I4 are maintained in fixed spaced parallel relation by means of the pair of angulated transverse bars 64 and 66. The angulated bars 64 and I56 are joined by means of the common sleeve 68 while the free ends of the bars 5 and 66 have sleeves I and I2 fixedly secured thereto. The sleeves 68, 70 and I2 are adapted to interconnect the sectional portions of the iongitudinally extending bars of the frame by means of the set screws I i provided in each of the sleeves.

When it is desired to extend the length of the frame, extension sections I5, 38 and 80 are provided, each of the extensions having a sleeve 82, 84, and 86, respectively, secured thereto. The sleeves 82, 84 and 30 are each provided with a set screw 80 whereby the extension can be fixedly secured to the rear sections of the longitudinally extending bars I2 and Hi, the forward ends of the extensions it, I8 and 80 being connected to the sleeves 68, 70 and I2 by means of the set screws in those sleeves.

Looking now at Figures 4, 5, 6 and 7, the means for supporting the stern of the boat will be more readily understood. The after end of the longitudinally extending center bar I2 is fixedly secured to the substantially rectangular hollow housing 90 which is fixedly carried by the transversely extending bar 38. A winch 92 is rotatably supported within the housing 90 and is comprised of two sections 94 and 86. Each of the sections 94 and 96 of the winch 02 has a cable 98 and I00, respectively, secured for winding thereon.

A shaft I02 has its rear end fixedly secured to the winch 92 for effecting rotation of the same. The shaft I02 is disposed in the hollow tubular bar I2 and extends outwardly of the forward end of the bar I2, as at I04. A handle of crank form is fixedly secured to the shaft at 104, the handle being designated by the numeral I06. A ratchet wheel I08 is fixedly secured to the shaft portion I04 and a pawl III] is pivotally carried by the upper forward end of the center bar I2 for engagement in the ratchet wheel I 08 whereby the shaft I06 can be maintained from rotation.

As seen best in Figure 8, the shaft I02 is of sectional form having forward and rear portions which can be connected by the inner sleeve H2 and pins H4. However, in the form shown in Figure 8, a sectional extension shaft IIB interconnects the forward and rear sections of the shaft I02 by means of the inner sleeves H2 and H2 with the pins 4 and H4.

Opposing end portions of the transverse bar 38 have strap holding means II secured thereto. The strap holding means is best disclosed in Figures 6 and 7 as including tubular elements IE8 having their ends fixedly secured to the U- shaped clamping elements I20. The U-shaped clamping elements I20 have lugs I22 extending through their leg portions with nuts I2 engaged thereon whereby the U-shaped elements I20 can be engaged over the bar 38 and clamped in preselected positions thereon. The bight portion I26 of the U-shaped element I20 is formed With a hanger loop whereby a resilient coil spring I28 can be supported within the tubular element I I 8. Each of the coil springs I28 terminates with a hook I30, the two hooks I30 providing means whereby the stern supporting strap I32 can be supported, the strap I32 having hooks I30 secured to its terminal portions.

U-shaped clamp elements I20 are each provided with outwardly extending pins I36 upon which a pulley sheave I38 is rotatably supported,

e a nut I40 retaining the pulley sheave I38 on the pin I 30.

As seen in Figure 3, the cables 98 and I00 are engaged over the pulley sheaves I38, their terminal hooks 99 being provided for engagement with the stern of a boat whereby the same can be lifted.

In view of the foregoing, it is believed that a boat carrier has been provided which. will accomplish all of the objects hereinabove set forth. Furthermore, in view of the simplicity of the structure of the present invention, it is believed that the manner in which the same is employed will be readily obvious to one skilled in the art.

When it is desired to support a boat by the carrier, the bow is engaged over the bow-supporting bar 34. The cables 98 and I00 are lowered so that the hooks 99 can be secured to the stern of the boat. The crank I06 is then rotated so that the winch sections 94 and respectively wind the cables 98 and I00 thereon. The stern of the boat will thereby be raised and can be maintained in raised positon until the strap I32 is disposed thereunder. The cables will, of course, be maintained in raised position by means of the ratchet and pawl arrangement at the forward end of the frame. It will thereby be seen that the boat will be resiliently supported by the boat carrier. Furthermore, should it be desired to accommodate a boat of greater length, the extensions can be inserted into the frame to provide an elongated frame.

In the embodiment preferred, the forward wheel I3 is of the crazy type, while the rear wheels 52 and 54% are of the caster type. After the trailer has been attached to the towing vehicle, the forward wheel of the trailer is removed.

The modified arrangement shown in Figure 9 includes the provision of elbows I50 joining tubular portions of the frame. The brake housings I52 of the wheels are fixedly secured to-each of the elbows I50, as by weld, conventional automobile size tires I58 being rotatably carried by the conventional spindle.
