BOATS.
Patented Oct. 21, 1919.
Application filed February 11, 1918. Serial No. 216,642.
To all whom it may concern Be it known that I, HARRY W BROADY, a citizen of the United States, and residing at Bayside, in the county of New York and State of New York, have invented a new and Improved Engaging and Disengaging Gear for Ships Boats, of which the following specification is a full disclosure.
This invention relates to improvements in engaging and disengaging gear for ships boats.
By the use of my invention, I am enabled to produce an engaging and disengaging gear which may be released under a load or when the boat is being water-borne or towed; and which will be so'arranged that all the parts of the device readjust themselves automatically for engaging so soon power is taken 0d the pull-chain and at the same time will lock the hook against movement when the gear reaches its engaging position so as to prevent releasing accidentally through any agency other than the pullchain. Furthermore, the said gear is so arranged that it will be impossible to lock or stick either in fully released position or in any other intermediate position.
Another feature of my invention enables the ring of the falls, when the device is in engaging position to be freely moved inwardly into engagement with the hook but will, without special manipulation, prevent outward movement of such ring to disengage the same while the hook is in such engaging position and said gear will furthermore automatioally free the ring from such restraint when the devicereaches'its releasing position.
To these ends I provide in combination with a pivoted and counterweighted tripping hook which is suitably supported, a power-multiplying device or system of levers, preferably pivotally mounted adjacent to the hook and connected thereto in such manner that when the counter weight swings the hook into engaging position it will also cause the lever parts of the device to be automatically moved into position to form a toggle joint and thus through their connection with the hook lock the same in such engaging position against movement by any other agency than through a suitable pullchain secured to such lever. Preferably the hook and counter weight are formed in two as the strain or parts and the counter weight is pivoted to the hook so that any movement thereof will cause the hook to be swung around its pivot from engaging to disengaging positions and vice versa. Furthermore, the lever parts are so arranged that one of them forms a continuation or shank of the hook and when such levers are actuated the hook will be caused to have a closing and opening move ment in relation to said shank part or lever so that the ring of the falls may be more readily freed when the parts are in releasing position. As illustrated, the pivoted tripping-hook has pivoted to it, what I shall term, a shank-lever provided with a suitable counter weight which shank lever forms a continuation Or shank of the hook and this shank lever furthermore has integrally formed therewith a rearward extension which has a pivotal connection with a link which is, in turn, pivoted to the supporting bracket adjacent to the hook pivot, the parts being arranged in such relationship that when the hook is in engaging position the pivotal connection first between the shank lever and hook and second, between the rear ward extension and the link, and, third, between link and supporting bracket, will be in alinemcnt and produce a toggle lockingjoint which will lock the hook against accidental movement in its engaging position and furthermore, these parts of the gear are so arranged that the said rearward extension will abut against the link pivot or a suitable hub thereon to limit its movement to engaging position and will abut against the hook pivot or a suitable hub thereon when it is moved to its extreme releasing position, in which position. the parts areprevented from looking.
When it is desired to provide an automatic ring-retaining device in combination with the gear. I preferably provide a pawl which is weighted with the counter weight and pivoted to the shank lever and so arranged as to move pivotally on the said shank lever a limited distance against the action of the said weight in one direction only so as to permit the ringto be moved through the mouth of the hook or through the space between the shank lever and the end of the hook in one direction but to prevent or stop any movement in the opposite direction so that when the ring is once in place it will be retained beneath the hook until the togglelever joint hereinabove described has been broken and the hook moved to releasing position, in which position the relative disposition of the hook and shank lever will be such as to completely free the mouth of the hook and to permit the exit of the ring therefrom.
Other objects will be in part obvious from the annexed drawing and in part indicated in connection therewith by the following analysis of this invention.
This invention accordingly also consists in the features .of construction, combination of part and in the unique relations of the members and in the relative proportioning and disposition thereof, all as more completely outlined herein and in said drawings.
To enable others skilled in the art so fully to comprehend the underlying features that they may embody the same by numerous modifications in structure and relationship of parts contemplated by this invention, drawings depicting a preferred form have been annexed as a part .of this disclosure, and in such drawings like characters of reference denote corresponding parts throughout all the views, of which:
Figure 1 is a lan view of a boat embodying an installation of my improved engaging and disengaging gear.
Fig. 2 is a large side elevation of one of the gears shown in Fig. 1;
Fig. 3 is a front elevation of the gear shown in Fig. :2;
Fig. 4 is a plan view of the gear shown in Figs. 1 to?) inclusive; r
Fig. 5 is a side elevation of a slightly modified installation of my said gear;
Fig. 6 is a planview of an installation shown in Fig. 5; I
F ig. 7 is a front elevation, partly in section, of the gear shown in Fig. 5,
Fig. 8 isanother side elevation of amodified form of my invention embodying a ringretaining pawl; V
Fig. 9 is a similar side elevation showing the gear in released position;
Fig. 10 is a section on the line 10-10 of Fig. 8; and
Fig. 11 is a'section on. the line 1111 of Fig. 8.
Referring nowto these drawings, 1 indicates a boat and 2 the, keel thereof. To the keel at opposite ends of the boat 1 are, as shown, mounted my improved disengaginggears, the gears at opposite ends being connected by pull-chains 3 to a common releasing handle 4. v
The engaging and disengaging gear which forms the subject matter of this invention, embodies, as shown, a hook 5 which is mounted on a fixed pivot 6 in a bracket 7 suitably secured by rivet or other fastening devices 8 to the keel 2 of the boat 1. To the rear end of the hook 5. is pivoted at 9*, what I Shall term, a shank lever 9 which, as shown in Figs. 1 to 7, is provided integrally with a counter weight 10 and has a rearwardly extending arm 11 which is pivoted at 12 to link 13 which, in turn, is pivoted at it to the bracket 7 The parts are so arranged that when the gear is in the engaging position shown in full lines in Figs. 2 and 5, the pivots at 9 12 and let will be in alinement with each other and a toggle-joint will be produced whereby the hook will be locked against movement except through the agency of the pull-chains 3 and the parts will automatically swing into position to form this toggle-joint through th action of the counter weight 10. As illustrated, the rearward extension 11 of the shank lever 9 is bifurcated, and when the gear isin engaging and locked position, the edge 11 of such eXten slOll will abut against the hub 13 ofthe link 14 so as to limit the rearward movement of the parts. lVhen the parts are, by a pull upon the chain 3, swung into releasing position as illustrated in dotted lines in Fig. 2, the said rearward extension, as shown particularly in Figs. 2 and 8, will abut against the hub 5? of the hook 5, as hown at 11 in Figs. 2 and 9, whereby the forward movement of the parts is limited and the device is prevented from locking in its disengaging position. In Figs. 5, 6 and 7 I have illustrated an installation of my gear supported by one of the thwarts 15 which is slotted as at 16 and provided with a supporting bracket 17, the installation being reinforced by reinforcing strips 18 which are mounted on the pivot'6 at one end and secured to double bracket 19 at the opposite end which is, in turn, connected to the keel 2 of the boat. These supporting strips have attached thereto, a rearward extension 20 in which the link 13 is pivoted. The supporting strips '19 also support a pulley-block 21, the pulleyblock 21 having a pulley 21 around which the chain 3 is adapted to be led. In other respects the installation is the same as that illustrated in Figs. 1 to 4.
In Figs. 8 to 11 I have illustrated a form of gear which is in all respects similar to the gear shown in Figs. 1 to i inclusive except that the shank lever instead of being pro vided with an integral counter weight is bifurcated at 9 and has pivoted thereto at 22.
a pawl 23 which has integrally formed therewith the counter weight 10. The pawl 23 is so arranged in relation to the shank lever '9 that it is free to move in one direction as illustrated in dotted lines in Fig. 8 against the action stopped from moving in the opposite direction by cotiperating abutinents 9 and 23 on the shank lever 9 and pawl 2-3, respectively. Obviously, a ring such as indicated in dotted of the weight 10 but is lines at 24 may be passed upwardly between the shank lever 9 and the end of the hook 5 by simply pressing the ringagainst the said pawl when thecounter weight 10 will be swung on its pivot to permit the entrance of such ring. So soon, however, as the ring passes the pawl the weight will automatically assume the position shown in full lines in Fig. 8 and the ring will thereupon be locked in position beneath the hook and above the pawl so that it will be impossible to release the same (without specially manipulating the weight) during the time the gear is in its engaging position. however, the shank lever and weight are swung forwardly by the pull-chain 3 the hook will be swung around on its pivot in such relationship to the said shank lever 9 as to free the mouth of the hook and permit the ring to move freely therefrom. So soon as the pull is relieved from chain 3, however, the weight 10 will cause the parts to resume the initial position shown in Fig. 8 and the pawl 23 will again assume its mouth-blocking position.
The operation of the device will be obvious from the foregoing description.
I claim:
1. The combination with a pivoted, counterweighted tripping hook and means for supporting the same, of power-increasing levers having a pivotal connection with the hook and a pivotal connection with a suitable support adjacent to the said hook, and means for actuating one of such levers to swing the hook 011 its pivot from engaging to disengaging position.
