This invention relates to a combined dock-A ing stall and boat brake, and anobject of the invention is the provision of an improved construction whereby the speedl of a boat 'en-V tering a docking stall may be rapidly retarded, and whereby a boat may be iirmly engaged within the stall without the use of tying lines. The invention is particularly adapted to small power craitor other water craft where it is desirable or necessary to approach la landing pier at a relativelyhigh speed and to rapidly reduce the speed; and

the invention also provides improved means for maintaining a boat docked at a landing pier, which means is simple in construction and entirely under the control of the operator or pilot of the boat. Other objects will appear hereinafter. The invention consists in the combinations 2o and arrangements of parts hereinafter described and claimed. l

` The invention will be best understood by reference to the accompanying drawings,

forming apart of this specification and in which:

,Figa l is a plan .view of a boat equippedr Y with the present invention in docked position in a docking stall; l

Fig. 2 is a cross-sectional view, taken sub- 3o stantially on the line 2--2 oi" Fig. 1;

stantially on thevline 7-7 of Fig. 3; and

Fig. 8 isa perspective viewk of one of the 1f right lbraking or holding shoes.

' As illustrated in the drawings,`the preferred embodiment of the invention is shown in association with a landing pier 11 having a longitudinally extending beam `12`adapted 5o to cooperate with the'braking shoes mounted pedal control and release device, taken subupon one side of the boat.l A guide` bumper l 13 having a guide beam 14 is disposed opposite thebeam 12 and in spaced relation thereto to afford ay docking stall for the boatV 15.V Beams 12 and 14 extend in parallel relation and are spaced apart a slightly greater dis tance than the greatest width ofthe boat to be received. rlhe guide bumper may be supported by vertical'standards 15 suitably se* cured by braces 17 to a cross member 18, which in turn is connected to the bracing 18 of the landingpier 11. Y l Y Y The braking and dockingmechanism preferably comprises a pair of shoe members 19 and 2O mounted on the right side of the boat and a corresponding pair of shoey members 21 and 22 mounted on the left lside of the boat. Theseshoe members vmay be mountedV on the upper surface of ythe deck as shown, or in any suitable place so as to be capable of a` pivotalv mounting land lateral extension or kprogection to engage the respective beams 12 and 14. In the preferred methodv of mounting shown, each of the

slice members

19 and 20 is keyed to a-vertically extending pin 23 journaled ina vbearing plate V24 secured to the deck 25. Below the plate 24, a block 26 is pinned to the shaft or pin 28 and is disposed on the opposite side of pivot pin 23- ifrom the longitudinal center line of the boat. A cap 27 is varranged to ybesec'ured to block 26 by bolts 28, and block 26l and cap 27 are .r v

provided with complementaryL grooves tol re'- ceive the right cable29.

The pivot pin'of shoe 2O carries a block 30 identical with block 26 and securedV in the Y same manner to the cable 29. The rear eX- tremity'of cable ,29 is connected to one end ofl'a tension, spring 81,' the opposite 'end'.of

which is connected to the frame of the boat. The effect of this construction and arrange'- mentis normally to maint-ain'lthe cable 29 in such position that-the

right hand shoes

19 and 20 are retractedso as not to extend bef yond the side of the boat, or in the position oft shoe 22 in Fig. 3. Cab-le 29 extends forwardly to pass under

sheaves

32 and 38.

mounted in suitable lna'ckets,arid then eX-. tends downwardly over sheave 34.or connection to arm ot footv pedalV 36 which is pivotally mounted upon bracket 37 secured to the floor 38 adjacent the pilots sea Shoes 21 and 22 are identical in mounting and arrangement with shoes i9 and 2O except to be in reverse position and mounted on the opposite side ot the boat. Consequently, the blocks are likewise disposed outwardly from the pivot pins for connection to cable 39, the rear extremity ol which is connected to tension spring 4:0 secured to the boat frame. Cable 39 extends forwardly to pass under sheaves l1 and 42 and thence downwardly over sheave 43 for connection to arm Thus it will be seen that upon `depression of the foot pedal 36 for manual operation of the mechanism, the respective shoe members will be projected outwardly from the sides of the beat to engage' the adjacent beams ot the docking stall.Y For the purpose vot maintaining the shoes in extended position,the foot pedal 86 may 'be provided-Witha pivoted locking pawl lll `lor rengagen'ient with a toothed segment 45 on the upper surtace ot the bracket 37, locking pawi'et being provided with a releasing extension 46. it will be noted that' the engaging surfaces ot the respective shoe members areA curved so as to slidably engage the stall' beams and oder sufficient frictional contact to vbringA the boat to a stop and also to maintain the boat in position vwhile docked. lior disengagement, itis merely necessary to 'depress the releasing projection 46 with the foot, whereupon tension springs 3l and l0 cause retraction of the respective shoe members through

cables

29 and 39, and the boat is 'free to move out otV the stall. The entirejmechanism is always under the direct control of the 'pilot or operator by mere manipulation of the toot pedal 36 and releasing extension e6, with-out -the necessity of leaving the boat. lt will be apparent that any desired tension or stress 'may be exerted on the respective shoe members by means ot' the foot pedall. To vi'acilitate entry and exit into and trompa stall, the beams are preferably iiared at the ends, as shown. l j Y While I'have villustrated and described the preferred form of construction tot: carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. l, therefore, do not wish to be limited to' the precise details of construction set forth, but vdesire to avail myself of such variati-ons and modiieations as come within the scope of Vthe appended claims. Y
