J. G. SJOBERG. SHIP LAUNCHING CONTROL DEVICE. APPLICATION FILED JUNE 30, 1919.
Patented May 4, 1920.
UNITED sTAT s PATENT OFFICE.
JOHNG. SJO'BERG, or OAKLAND, GALIFORNIA.
SHIP-LAUNCHING CONTROL DEVICE.
Application filed June 30, 1919.
To all whom it may concern: 7
Be it known that I, JOHN G. SJoBnnG, a citizen of the United States, residing at Oakland in the county of Alameda and State of California, have invented certaln new and useful Improvements in Ship- Launching Control Devices, of which the following is a specification.
My invention is a ship launching control device.
In this specification and the annexed drawing I disclose my invention in the form which I consider the best, but I do not limit my invention to such form because it may be embodied in other forms and it is to be understood that in and by the claims following the description herein I intend to cover my invention in whatever form it may be embodied.
Referring to the drawing:
Figure 1 is a side view of my invention applied to a ship way.
Fig. 2 is an enlarged side view of my invention.
Fig. 3 is an end view of one of the shoes of the shore bar.
In the drawing 1 indicates a ship way including the stationary supporting frame 2 and the slide frame 3 slidable on frame 2, on which slide frame are the cradles 4 in which rest a ship 5. To the frame 2 is secured an abutment bar 6 and to the frame 3 is secured an abutment bar 7, between the ends of which are interposed a shore bar'8 which holds the slide 3 on the frame 2.
. Patented May 4, 1920'.
Serial No. 307,586.
' frame 2 and by a rope 29 to the swinging arm of trigger 22.
Before the ship is launched the lever 15 is held as shown in the. drawing by the engagement of trigger 22'with eye 21 with the latch 17 extended through slot 13 into notch 18,and the weight 27 is suspended from the frame 2 by rope 28. The engagement of latch 17 with notch 18 prevents the shore bar from being forced downward in any way and disengaged from the abutment bar 6 so as to launch the ship.
To launch the ship the rope 28 is cut, whereupon the weight 27 drops and disengages the trigger 22 from eye 21; the lever 15, under the influence of weight 20 is swung down, disengaging the latch 17 from notch 18 and causing the cam 19 to engage the bottom of shoe 9; and the weight 20, assisted by the cam 19 engaging shoe 9, withdraws the shore bar 11 downward out of engagement with abutment bars 6 and 7, lug 26 engaging the under surface of shoe 10 and preventing the upper end of the shore bar from flying up, thus releasing frame 3 and launching the ship.
Having described my invention, I claim:'
1. In combination, abutments on the sta tionary and sliding frames respectively of a ship way, a shore bar interposed between said abutments, locking means for one end of said shore bar, and means for preventing the other end of said bar from flying upward when the bar is disengaged at its looking end.
2. In combination, abutments on the stationary and sliding frames respectively of a ship way, a shore bar interposed between saidabutments, a lever 011 said shore bar, a latch on said lever for engaging one of said abutments to hold the bar against said abutment, and means for swinging said lever to disengage said latch from said abutment.
3. In combination, abutments on the stationary and sliding frames respectively of a ship way, a shore bar interposed between said abutments, a weighted lever pivoted on bar against said abutment, and a trigger for holding said lever with said latch in engagement with said abutment.
4. In combination, abutments on the sta tionary and sliding frames respectively of a ship way, a shore bar interposed between said abutments, a weighted lever pivoted on said shore bar, a latch on said lever for engaging one of said abutments to lock said bar against said abutment, a trigger 'for holding said lever with said latch in engagement with said abutment, and a weight connected to said trigger but suspended from, the ship way before launching the ship.
5. In combination, abutments on the stationary and sliding frames respectively of a "ship way, a shore bar interposed between said abutment's, locking means for one end of said shore bar, and a lug on the other end of said bar for engaging the adjacent abut-V ment to prevent said end of the bar from flying up when the bar is disengaged at its I locking end.
6. In combination, abutments on the stationary and sliding frames respectivelyvof a ship way, a shore bar interposed between said abutments,a Weighted lever pivoted on said shore bar, a latch on said lever for engagingvone of said abutments to hold the JOHN G. sJoBERe.
