This invention apapertains'ito novel -and useful inrprovements in carriers for boats.

object of th-is invention is to support -a'looat -or the like in an improved manner-andlhy improved means. This will enable the boat to be loaded or unloaded without lifting the boat manually from the boaL-ts loading position, Bin water or out, and the elimination of time in loading or unloading "the boat.

Another object of this -invention-is to :'support a boat at loothiront and rear ends thereof, :both of the means for-supporting the "boat being operable at the front end of the trailer.

Another object of th-is invention is toswingingly mount the rear clamping means for "the l boat 'i-n order -that the actual clamping portion of the olamping means may swing from thesides of the boat to 't'he undersuriaoethereof, renderingit possible to simply pull the trailer relieve the boat and actuate the -cla'miping means :in order-to engage the undersuriaoe 0f :saidiiboat.

"As is well, known in the art there is a gr'eat :number 'of devices, for transporting boats from one location to another. It' :is therefore, one 0f the-prime :purposesv of the pre'sent invention to limp-rove enerally on, the :structure of this class pf invention through :the medium 0f supplying independently operablewclamping means at the front and-rear end o;f--;ama-in:frame; this facilitates loading and unloading a boat in or out the Water, the a earsclazmpingrmeans engaging the under surface :of "a shoot after a swinging movement -of the rclam ping devices has been efected.

forks

30 and 32 respectively. Each of the forks carries a wheel 34 with suitable means for journalling the wheel within the forks. Thus, the frame is roadable and, splash guards 36 may be supplied in association with the forks to serve their usual and conventional function.

It is noted by an inspection of Figure 1 that the rear of the frame is substantially open in order that outboard motors and the like may be easily accommodated without interference. Also positioned at and adjacent this rear portion of the frame is means for clamping the under surface of an ordinary boat. This means is symmetrical and includes a small plate 40 rigidly secured to the said

cross members

24 and 26 thereby forming a platform. A sleeve 42 is positioned on the said platform 40 and is maintained in place through the use of a stud 44 which is anchored This stud also such as the nut 46 and a suitable lock washer.

By the above described structure it is appreciated that the sleeve 42 is mounted for rotation on the platform 40. A flat bar 48 is attached to the top portion of the said sleeve 42 and has

pitmans

50 and 52 respectively pivotally associated therewith. These pitman rods may be seen best in Figure 6 and are obviously tubular with an extensible member maintained in place through rocking arm 60 by welding, brazing or other suitable means. This sleeve type bearing 62 is journaled on the upper member of one of the frame sides thereby allowing the rocking rod or arm 60 to pivot about the side to which it is appurtenant.

Viewing Figure 4 it will be seen that the rocking arm or rod 80 is positioned in a non-perpendicular relation relative to the longitudinal axis of the upper frame or truss member thereby allowing the swinging or rocking rod 60 to describe an arcuate path in engaging the under surface of a boat. In order to prohibit movement a collar 64 may be welded, brazed or otherwise rigidly secured to the upper member of the frame for engagement with the sleeve 62. serves the purpose of a thrust bearing and the cross member 24 limits the travel of the sleeve This collar 64 62 in the opposite direction, also serving the purpose of a thrust bearing. Suitably positioned at the lowermost portion of the rocking rod 60 is a plate 68, it being padded, which operatively engages the under surface of the boat thereby maintaining it in the elevated or raised position. 'Means is provided for actuating the said rocking arm 60 and the complemental rocking arm (unnumbered) which is on the oppositeside (I0) of the frame. The preferred means includes a relatively long rod I2 which is pivotally secured to an arm I4. The said arm I4 is in turn rigidly associated with the said sleeve 42 as is seen in Fig- I ure 4.

A turnbuckle device I6 is interposed in the length of the rod I2 for the purposes of adjustability. At the opposite end of the said rod I2 there is an arcuate portion I8 which is connected with an operating lever 80 through the medium of a conventional pivot pin 82. .The said pivot-r .400 is pivoted to a bracket I02.

pin 82 also extends through one end of a pivotally mounted bracket 84. The said bracket 84 is attached to the substantially U-shaped cross member or platform I6 by means of the upstanding perches 86. Of course a suitable pivot pin which may be in the form of a bolt 88 extends through both perches and an end of the bracket 84.

The bracket 84 is an integral part of the operating lever or handle 80. For locking purposes a pin 90 is supplied in suitable aligned apertures in the bracket 84 and in the lever 80. Thus, by placing the pin within the aligned apertures mentioned above and in a suitable aperture in a bracket 92, which is attached rigidly to the platform I6, the rod I2 is maintained in a selected position thereby retaining the rocking rods 80 in selected position.

Positioned adjacent the forward end of the said frame is a second locking device which is adapted to engage and retain the forward end of a boat in position within the frame. On the front portion of the boat a bracket is bolted thereon and is used in this connection. A lever This bracket I02 is, in turn, associated with an angle plate I04 and the angle plate is attached directly at the forwardmost portion of the frame. The actuating lever I as disclosed in Figure 2 is in one pivoted position. In this position a pin I08 may be passed through apertures in a small bracket I06 which is attached to the draw bar I8 for the purpose of holding the lever I00 in the illustrated position. A chain H0 is supplied connecting the pin I08 to the bracket I06 in order that it will not be inadvertently lost. The operation is deemed readily apparent, as the lever is simply placed within the bracket I06 and the pin I08 clamps it firmly in place.

At the inner end of the said lever I00 there is a link I09 which is pivotally secured thereto. This link has a substantially V-shaped plate II2 welded or otherwise rigidly secured thereto which clampingly engages the bracket I I3 bolted to the boats front end. Thus, the boat is held at its forward end in the raised or elevated position.

While there has been described and illustrated but a preferred form of the invention, it is apframe and a draw bar attached at the forward end thereof, means swingingly mounted adjacent the rear of the frame for clampingly engaging the bottom portion of a boat, means for actuating said clamping means, said actuation means including a pivot mounted on said frame, pitman rods attached to said pivot, and means positioned at the forward end of same frame for rotatin said pivot, a lever pivotally mounted at the forward end of said frame, means for locking said lever in a predetermined position, a link pivotally mounted at one end of said lever and a plate secured to said link adapted to clampingly engage the forward end of a boat.

2. The combination of claim 1 and said locking means including a bracket associated with said frame and a pin detachably mounted on said bracket.

3. A boat trailer comprising a frame having a draw bar attached to the front end thereof and having'an open back and, rocking arms swingingly mounted adjacent the rear end of the frame and swingable laterally of the frame for clampingly engaging the bottom portion of a boat, a vertically disposed'pivot secured to said frame adjacent the rear open end, pitman rods secured to said rocking arms, a bar mounted on said pivot for pivotal movement in a horizontal plane and having said pitman rods secured thereto whereby upon movement of said bar, said rocking arms are swung inwardly and outwardly of said frame, means disposed at the forward end of said frame for operating said bar including a lever pivotally carried by said frame by means of a horizontally disposed pivot so that said lever is movable in a vertical plane, means operatively connected with said draw bar releasably retaining said lever in one position, means including a link connecting said lever with said bar so that pivotal movement of said lever is reflected in pivotal movement of said bar, and a locking assembly partially carried by said lever and by the forward end of a boat for releasably supporting the forward end of the boat.

4. The combination of claim 3 and said locking assembly consisting of a bracket, 9. link pivoted to said lever and a member carried by said link releasably retained in said bracket.
