STOWING AND LOWERING BOATS.

Specification of Letters Patent.

Patented'Feb.4,1913.

Application filed June 1, 1912. Serial No. 701,054.

T 0 all whom it may concern:

Be it known that'l, HENRY ST. G. LIN.D'- SAY. a subject of the King of Great Britain, residing at Ottawsi,.in.the Province of Ontario, Canada, have invented certain new and useful Improvements in the Stow ng and Lowering of Boats, of which the following is a specification.

v invention relates to improvements in the stowing and lowering of boats on board ship as described in the present specitieation and illustrated by the accompanying drawings that. form part of the. same.

The invention consists essentially of a boat ehoek mounted through a swivel on a carrier provided with brake meehanisni and (amine rollers whereby said carrier is adapted to run on rails or launching ways suitably secured to the ship (leek; said rails being arranged transversely of said (leek whereby. in rombinat-ion with davits. boats can be lowered from one or both sides of a ship. The movement of the boats on the rails being eontrolled by said brake inertiauism. .\pertnres in said rails adapted to reeeive stops for firmly seem-hr; the boats when not in use.

The objeet of my invention is to provide a new. simple. etteetive. and inexpensive means for launrhing one or more boats from a ship under all eonditions oi weather.

further objet-t is to provide. means for slowing a number of boats on portions of the le kotherwise not used andin suth mailn-zu' that. when required. they will be easilv aeressible and readily lowered. it new essary irom both sides of the ship simub taneonslv.

'ith. these and ther objeets in view referenre now had to the aet-oiupanying drawings in \\'lll('ll like numerals of reter (nee indi ate eorrespondin; 'parts in eaeh figure. and in \\'lll('lt.

-l"i';{nre 1. is a plan view of a series of boats stowed side by side on rails extend 111;: transversely aeross the ship. Fig. 2. is a side elevation of a boat mounted on my deviee. Fig. l. is an end view partly in seetion of my invention. Fig. 4. is an enlarged front view showing relative. positions of roller and operating rain lever. Fig. 5. is a plan view of a rail with (-leats or stops in po ition.

. Referring to the drawings, 1 is the deck of the ship. 2 the boat and 3 (lavits.

4 are rails arranged transversely across thedeck 1 and secured fixedly thereto in any suitable manner. i

5 is the check formed with a step-bearing 5 adapted to engage with the supporting pin 6 on the earrier ti. Said supporting pin forming a swivel with the chock. The top of the former being threaded to receive a lock-bolt if necessary to more firmly se ure the latter. The carrier 6 is adapted to fit over, and on one side at 11, to overlap. the tread of the rail, traveling on same by means of the rollers 99 earriod in said earrier on the axle 10. The other side of the carrier 6, is formed at 6 to carry a lever 7 and the friction roller 8, on the axle 8'. forming a brake for said Farrier; whereby its travel on the rail is fully controlled and regulated.

12 -t2 are cleats or stops formed with pins lit-A3 adapted to engage with the apertures 14 in the rails. While here shown in Fig. 2-3 as one. on 011(11 side of the carrier (1. two each side may be used with advantage. The boat being thus held more set-urely in position whennot in use. These stops are provided with Ihant-lling means in the form of rings for pulling them up when the boats are about. to be lowered. The apertures H may he continued through the base ol the rail it neeessary.

'lo launeh the boat. thestops l2- ll' are first pulled out when the boat on its ehook will slide down the rails quiekly and smoothly by means of the, rollers 9-9'. The length of the davits with suspending taekle being arranged the sliding will be avt-oniplished without any jerky action. To cheek the boat in its travel or control its paee. so that. it will not pass out too quickly, it is only neeessary to' apply the brake nieehanism by Pt2ltlfl;j the lever 7, which in turn will operate the friction roller 8 against the under part of the rail. To replan the boats after being hoisted from the water, they are lowered on to the waiting ehoeks. eat-h pair of same on being loaded. being moved-up the rails and secured in their plaees hv replaeing the stops 1- \Vith my invention any number of boats that can be aeoommodated side. by side on the rails may be lowered on either side of the ship, as required.

The brakeaneehanism consists more partieularly of the lever 7 adapted to engage the square end of the axle 8. Said axle being adapted to the eccentrically mounted roller 8, fixedly secured thereto said axle being provided at 8 with a suitable bearing to work in freely.

The operating handle of the lever 7 can be made detachable for more convenient storage, and is provided with a friction pin 15 to more securely retain it in position.

What I claim for my invention is LA device of the class described comprising launching-rails, chocks, with swivels, mounted on carriers, rollers in said carriers adapted to travel on said rails; one side of thecarrier overlapping said rail, a friction brake supported by the extended other side of the carrier; operating means for said brake; apertures in said rails adapted to receive securing means for stops or cleats adapted to hold said chock-carrier securely in position.

2. In a device of the class described the combination with launching rails of a chock mounted through a swivel on a carrier adapted to travel on said rails provided with brake-mechanism whereby the travel of said chock is controlled.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses at the city of Ottawa, Province of Ontario, this 18th day of May,

H. ST. G. LINDSAY. Witnesses:

WV. T. CUFEE-QUIN, J. THOS. ROWAN.
