BER'I'I-I MOUNTING.

Application filed April 2, 1925.

To all whom it may concern:

Be it known that we, EMIL Nrsnol and EMIL NYMAN, citizens of Finland, residing at Hoquiam, in the county of Grays Harbor and State of IVashington, have invented certain new and useful Improvements in Berth Mountings, of which the following is a specification, reference being'had to the accompanying drawings.

This invention relates to mountings for ships7 beds or berths and more particularly to a mounting so constructed as to elminate strain of the bed and to maintain the bed at all times in horizont-al position.

A further and more specific object of the invention is the improvement of gimbal joint structure employed for supporting the bed enabling the production thereof at a moderate rate while at the same time increasing the rigidity of the structure.

These and other objects We attain by the construction shown in the accompanying drawings, Wherein for the purpose of illustration is shown a preferred embodiment` of our invention and whereiiu- Figure 1 is a perspective view of a berth supported in accordance with our invention;

Figure 2 is a vertical sectional view through the gimbal joint;

Figure 3 is a perspective of the cross bars of the gimbal joint; and

Figure 4- is detailed sectional view showing the mounting of the supports for the bed upon the gimbal joint.

Referring now more particularly to the drawings, the numeral 10 indicates a Ceiling attached support in the form of an inverted U, the central portion of which is rigidly secured to a hanger 11 which is in turn rigidly secured to the ceiling 12, as at 13.

The ends of the arms of the U-shaped support engage with pivots 111 formed by directing through a gimbal ring 15 a bar 16 which is circular in cross section and of sufficient length to project beyond the side faces of the ring. rI`his bar has its under surface notched, as at 17, for the passage of an oppositely notched similar bar 18, the ends of which likewise project beyond the ring 15 and are formed with pivots 19 for the reception of supports 20 for a bed 21. It Will be obviousv that the universal movement provided by the gimbal ring and its connection to the supports 10 and 20 will permit the bed at all times to rema-in in horizontal position regardless of the angle which is assumed by Serial Ne. 20,253.

the vessel in which the berth is arranged. Particular attention is directed to the construction of this gimbal ring.V The bars 16 and. 18 connected to: the uppor and lower supports respectively are notched upon theirl under and upper faces respectively to permit their passage and at the same time permit use of a straight bar.

It Will be obvious that strain of weight supported from the ring upon the ends 19 of the bar 18 will tend to flex the center of this bar upwardly and with the weight of the ring itself and of this load Which is applied to the outer ends or pivots 14 of the 'bar 16 will tend to fiex the center of the bar 16 downwardly. `I1`hese bars will, therefore, tend to flex in opposite directions with substantially equal forces, oifsetting the stress Which s placed thereon and thereby permitting the use of lighter bars 16, 18, that could otherwise be employed. Furthermore, the interengagement of these bars at the notches thereof Will elfectually prevent longitudinal Shifting of either of the bars and the pivots 14 and 19 Will, therefore, always be properly projected for engagement with their respecring and having notched engagement one` with the other, the ends of said bars projecting to provide pivots for engagement With the respective supports.

2. In a support for ships7 berths, a support adapted to be engaged With a ceiling and embodying spaced arms, a second support havinn" spaced arms secured to the berth and projecting upwardly therefrom, and a gimbal ring structure for connecting said supports comprising a` ring, bars extending at right angles an'd diametrically of said ring and having notched engagement one with the other, the ends of said bars projest-ing to provide pivots for engagement With the respective supports, the bar the ends of Which is engaged With the Ceiling attached support being notched upon its under surface, the bar engaged With the berth support being notched upon its upper surface Whereby strains applied to either of said bars tend to flex the bar from the other of the bars.

3. In a support for ships7 berths, a support adapted to be engaged with a Ceiling and elnbodying spaced arms, a second support having spaced arms secured to the berth and projettin: v rgwardiy therefroin, and a giinbai ring structure for connecting said supports eonoprisin;v a ring, crossed dainetricaily extending bars carried by said ring and With Which the ends of said arms are enoaged, said bars having engagenient one With the other Whereby each opposes flexure of the other upon the application of Weight to said supports through the ring.

In testlnony Whereof we hereunto affix our signatures.
