UNITED smarts Parser. easier @JosEPH roncinn, or Bani/mama, wasrirneron- 1 LIFE-BOAT ATTACHMENT.

To all whom z't may concern? fBe it known that I, Josnrn FQRCIER, a 'c t1- zen of the United States,res1d1ng at Bremerton, in the county of Kitsap and State of Washington, have invented new and 11881 1111 Improvements in Life-BoatAtta'chments, of which the following is a specification.

V This invention relates to life saving apparatus and more particularly toapparatusfor raising, lowering and releasing life boats.

Oneof the principal objects of the inven tion is to provide a novel type of raising and lowering winch which may be shifted about over the deck of thevessel and wh ch w ll take care of both davit cables whereby simultaneous action of these cables is assured. Another object of the lnventlon is to provide a simple and efficient releasingi'mechanism whereby both davit cables may be simultaneously released from the boat when lowered and which mechanism is so 0011- structed that it may be operated by a single.

man.

Further objects of the invention will appear as the following specific description 1s read in connection with the accompany ng drawings which form a part of th s application and in which Figure 1 is a top plan view showing the arrangement of the raising andlower ng mechanism; Fig. 2 is a rear elevation of the raising and lowering mechanism on a somewhat enlarged scale; Fig. 3 is a detall sectional view taken on the line 3.3 of Fig. 1; Fig. 41 is a detail top plan view of the boat; Fig. 5 is a longitudinal section therethrough; Fig. 6 is a vertical sectional view taken on the line 66 of Fig. 5; Fig. 7 isa simllar view takenon the line 7-7ofFig. 5, and Fig. 8 is an enlarged top plan view of the winch.

Referring more particularly to the drawings 1 represents the deck of the vessel,in this instance shownprovided with a pair of bolt supporting bolsters 2 upon which the lift boat 3 of any suitable construction is adapted to rest when not in use. These bolsters have connected thereto lashing of any preferred type but preferably of the type shown and indicated at 4.

Mounted upon the deck for free-swinging movement are the usual clavits 5 carryingthe pulleys 6and 7 over which the cables 8 and 9 are adapted to pass, each cable being: provided at one terminal, withsuitable'hooks Specification of Letters latent. Patentedfeb; 15 1916;- Application filed may 14, 1915., seriai uo. 28,237. i I 7' i 10. The cables Sand .9 also pass over the v pulleys llsecured to the deck. I 1

Beforeproceeding to describe the winch construction, I shall first thoroughly---de vr scribe the construction of the releasing mech-- anism which is carried bythe boat, Secured to the bow and stem.p1eces are brackets 12 fee having pivotally mounted thereon the hook engaging pins 13 whose free ends are retainedin operative,position'loy the yoke members 14 and 15 also pivoted in the brackets. These yokemembers are arranged to engageover thev free ends of the pins so that thev are held in horizontal position and are operated in the following manner: EX-- tending longitudinally of the boat and mounted betweenjcertain of the thwarts or cross braces is a supporting beam '16 upon 7 l V which is pivoted arlever '17 the pivot bolt which extends between the thwarts and is mounted in suitable bearings carried thereby. The lever 17 is provided with a painteradapted to actuate the lever for releasing both yoke members 1 1 and 15 from the hook engaging pins or fingers 18 simultaneously."

This construction obviates the employment of a man at each end of the boat for releas ing the cable hooks fromv the usual eyeswhich project above the deck. V e To properly actuate the cables 8 and 9 in raising and lowering the boat there is provided a winch ofnovel type consisting of a base 20 mounted upon supporting wheels 21' so as to be readily moved about the deck.

Mounted upon the 'base are separate paths of bearing brackets or frames'22 and rota tably mounted in each bearing is a drum shaft 23 which is driven through a crank shaft 2% geared to the drum shaft as shown.

Both of the drum shafts 23 are connected to the'cables 8 and 9 in any suitable manner and these shaftsextend in a plane normal to the line of the cable and are connected together in their inner ends by a universal joint 25. Each drum :shaft has secured thereon a brake drum 26'over which extends a flexible brake band 27 secured atone end tothe base or platform 20 and at the 0pposite end toone leg of a \lrshapedbrake beam 28, thefree ends of which are pivoted to the character, as one boat is lowered the Winch may be readily moved to other boats on the deck or Where the boats arearranged in groups or-on skids the Winch may be anchored to the deck in any suitable manner.

What is claimed is: 1. In life saving apparatus, the combination With boat davits and cables therefor of means for operating the cables comprising a, portable base, cable drums mounted thereon and arranged at'an angle to each other, means for simultaneously operating said drums, brakes therefor and a common" con-,

trolling'means for the brakes.

2. In life savingapparatus, the combination with boat davits and cables therefor, of

Winding mechanism for the cables comprising a portable base, angularly positioned;

drum shafts, means for connecting the drum shafts for simultaneous operation, operating means for the drum shafts, separate brake bands for said shafts, a lever common to both bands and means for actuatingthe .7

lever.

3. In life saving apparatus, the combine-,

tion With boat davits and cables therefor,of means for Winding and unwindlng the cablescomprising angularly positioned shafts un1-- versally'connected together, a brake for each;

shaft, a V-shaped lever connected to the brakes and an operating device for the lever} c 4. In a life-saving apparatus, the combination with boat davits and cables therefor, of i means for Winding and unwinding the cables comprising angularly positioned shafts universally connected together, a brakefor each shaft, an operating lever common to both brakes and means for operating the lever to apply the brake. a In testimony whereof I affix my signature in presencelof tWo Witnesses.
