Aug. 21, 1951 B. D. S. BLAGDEN MOVABLE SHELTER FOR BOATS Filed Feb. 17, 1948 2 Sheets-Sheet 2 k 1' My Ben Um? [2 S. B/agden By his Attorneys Patented Aug. 21, 1951 I UNITED STATES PATENT OFFICE 12 Claims.
My invention relates to movable shelters for boats, and more particularly to shelters which are associated with marine railways.
It has 1011;; been a problem for small boat owners and amateur yachtsmen to find some suitable and inexpensive means for storing their craft during the winter months and for sheltering them while they are being used. Indeed, the expense and labor associated with providing shelter and storage for small boats are major factors in preventing many persons of average means from owning pleasure craft.
The present invention provides in one simple and inexpensive unit a means whereby a boat may be launched in spring, moored and sheltered during the pleasant months of summer and early fall and safely stored during the winter, free from the crushing, moving and lifting action of ice. This is accomplished through the agency of a novel marine railway upon which is mounted my movable boathouse. The boat is stored suspended within the boathouse during the winter months. When it is desired to launch the craft, my boathouse is run down the novel railway a suitable distance and the boat lowered into the water. My boathouse in this position serves as a convenient docking structure and protects the boat from the deteriorating effects of constant exposure to wind and rain. Further features and advantages will appear in the detailed description which follows.
In the drawings:
Figure 1 is a perspective view showing a portion of my novel marine railway and movable boathouse, partly cut away, as they appear in the preferred embodiment of my invention;
Figure 2 is a View in side elevation on a smaller scale of the preferred embodiment of my movable shelter when mounted on a gradually sloping shore, with the boathouse in the winter or storage position and the tracks raised clear of the ice, the side being partly broken away to show the interior;
Figure 3 is a view in side elevation similar to Fig. 2, showing the boathouse in the summer or docking position and the boat in the water;
Figure 4 is a view in side elevation of a slightly modified embodiment of my movable shelter when mounted on a more level shore, showing the boathouse in storage position, the side being partly broken away;
Figure 5 is a view similar to Fig. 4, showing the boathouse in position for summer use; While Figure 6 is a side elevation of the water line section of the marine railway of Fig. 1, showing the details of construction of this section.
The railway, as shown in the drawings, has a railed track with an under-water section I and a shore section 2 connected together by a pivoted connecting section 3. The under-water section is permanently fixed to the bottom of the lake, river or bay, at a depth greater than that to which ice usually forms. The tracks are on piles i, prefer ably made of concrete. The lower end of the underwater section is preferably curved upwardly to provide a stop 5 for the boathouse.
The railed track of the shore section is also laid on concrete piles 6. At the water end of this section is a hinge l to which is pivotally attached the connecting section 3. If desired, this connecting section may have guides 8 at its lower end which fit into sockets 9 of a special under-water base cross-tie I0, as shown in Fig. 6.
The movable boathouse has a frame I! covered by sheet metal or other suitable material. This forms roof and sides to enclose the house. The frame is supported on vertically extensible supports l2 upon which are located flanged wheels l3 designed to fit the rails. From the top of the frame depend adjustable suspensory members which are means to carry the boat. For this purpose I have shown screw jacks M (Fig. 1) These are provided with hooks I5 at their lower ends to engage suitable members such as eyebolts 16 on the boat [1. At the rear or land end of the boathouse is secured a main Windlass [8. Upon this is wound a flexible element such as a stout rope, chain or cable I9, one end of which may be secured to a tree 20 or other anchoring means. A door 2| and a platform 22 are preferably constructed on one side of the boathouse to provide access to the Windlass l8 and to the boat. Another Windlass 23, which I term the track windlass, is attached to one of the vertical water-side frame members, and a flexible element such as a rope, chain or cable 24 is run from it through a pulley 25 at the top of the frame to the last cross-tie 2B of the connecting section of the railway (Figs. 1 and 6).
To best describe the functions of the various members of my invention I will now describe the cycle of operations involved in launching, mooring and storing a boat in my novel boathouse.
Assume that the boathouse has been drawn up on the land and is in the position of Fig. 1, 2 or 4. The first step in launching is to lower the connecting section 3 of the railway by means of the track Windlass 23. The lower end of the connecting section on being lowered comes into correct alignment with the under-water section through the agency of the guide 8. Next, the house itself is lowered down along the rails by unwinding the main Windlass l8. As the boathouse descends into the water, adjustments are made on the extensible supports l2 to maintain the house horizontal. These supports also permit adjustment of the house to the desired distance above the water, and allow for changes in water level. When the rope has been payed out of the main Windlass the desired amount or the wheels I3 of the boathouse are in contact with the stops 5, the boat l'i may be lowered into the water by turning the screw jacks [4 until buoyancy relieves the tension on them, and then disconnecting the hooks [5 from the eyebolts 16. The boat is now launched and free to sail.
If desired, the boathouse may be left in a lowered position for the entire season, the extensible supports l2 being adjusted to conform with the depth of water. In this way a convenient mooring is provided. The boat may be left in the .water from day to day or easily removed and suspended from the screw jacks l4.
At the end of the season when it is desired to .store the craft, it is first raised out of the water on the screw jacks i i. If desired, the full weight of the boat need not be taken up by operation of the screw jacks l4, .and instead the raising of the boathouse by the main Windlass i8 can be used to lift the boat out.of the water. The boathouse is drawn up on the shore by reeling in on the main Windlass 18. If desired the boat may be lowered to rest on blocks or a cradle (not shown) for winter storage, thus removing the load from the frame. Finally, to prevent damage by ice to the railway itself, the connecting section 3 of the track is drawn up by winding in the cable 24 on the track Windlass 23.
Thus my invention provides in one simple, con- .venient unit, facilities for storing, mooring, sheltering and launching a small boat. The structure according to my invention lends itself very easily to prefabrication, in that it may be :packed in small cases for shipment and easily assembled by the average man, without any special skill ,or knowledge. It is an important advantage of my invention that, unlike permanent .boathouses, it can be made from relatively light materials because no part of the structure is left .exposed to the crushing, moving or lifting action of ice. Use of such light materials contributes heavily toward decreasing the cost of Construc- .tion.
