Application August 24,1945, Serial No. 612,518

(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 7 Claims.

1.. This invention relates to an adjustable support or stanchion for temporary holding jobs.

One instance in which this support is particularly useful is in ship construction for temporarlly holding fittings, such as berthing sockets,

batten sockets, electric light receptacles, switch boxes, overhead wireway brackets, coamings, etc., in place while they are being welded or otherwise permanently secured. In large ships, as for example aircraft carriers, there are thousands of such fittings to be installed, and use of the device of this invention enables an invaluable saving to be made in time and labor.

An object of this invention is to provide an adjustable support for temporarily holding fittings until they are permanently secured.

Another object is to provide an adjustable support for temporarily holding, levelling and aligning fittings until they are permanently secured.

A further object is to provide an adjustable stanchion adapted to be used in installing fittings on a ship upon building ways.

Further objects and advantages of this invention, as well as its construction, arrangement and operation will be apparent from the following description and claims in connection with the accompanying drawing, in which Fig. 1 is a front elevation partly broken away of the adjustable support of this invention,

Fig. 2 is a front elevation partly in section of the inner member of the support shown in Fig. 1,

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2

Fig. 4 is a detailed plan view of the level attachment upon the support shown in'Figure 1,

Fig. 5 is a detailed side view of the level attachment shown in Fig. 4,

Fig. 6 is a side view partly in section of one type of top attachment adapted to be secured to the inner member shown in Fig. 2;

Fig. '7 is a side view of another type of top attachment adapted to besecured to the inner member shown in Fig. 2, and

Fig. '8 is a side View of one type of bottom attachment adapted to be secured to the bottom of the support shown in Fig. 1. r

Fig, 1 shows a sleeve :5, having a longitudinal slot H, which is provided with notches 12 at spaced intervals. An inner member, generally designated as i 3, telescopically engages the sleeve 19. The inner member l3, shown in detail in Fig. 2, comprises a base piece i4 having a connecting member i5 of smaller diameter fixedly secured thereto as atiii. The connecting member I5 telescopically engages a top member I6 and is prevented from becoming detached therefrom when extended by a head I! which engages a washer l8 fixed to the top member 15. A coil spring [9 bearing upon the base piece l4 and the washer IS on the top member it normally keeps the top member I6 and base piece l4 apart to the full limit allowed by the connecting member I5.

The base piece Id of the inner member I3 is provided with a lifting handle 20, shown in detail in Figure 3, which extends through the longitudinal slot II in the sleeve ID and is adapted to be placed in any one of the notches l2 (Fig. 1)

A levelling attachment, generally designated as 2| (Fig. 1) is provided at a convenient height on the sleeve l 0 of the support for enabling the work to be levelled or aligned simultaneously with being supported. This attachment 2|, shown in detail in Figs. 4 and 5, comprises a bracket 22 attached to the sleeve H] as at 23 and extending normally therefrom. A table 24 having a transverse level 25 and a longitudinal level 26 mounted thereon is hinged upon the bracket 22 as at 28. A groove 29 is provided at each side of the table 24 for slidably receiving a cover member 30, which i used for protecting the levels 25 and 26 when overhead work is being done. A wedge 3! (Fig. 1) ,having a sloping edge 32, of a declivity corres onding to the decliviti of a ship upon building ways, is provided for insertion between the bracket 22 and table 24 when the stanchion is to be used upon ships on ways.

The bottom of the sleeve i0 and the top of the inner member l3 are provided with attachments 34 and 35, respectively, which are shaped to hold the fittings to be installed or are designed to rest upon the deck or bulkhead as the case may be. The bottom 'attachmentt i is provided with 'a' shank 36 of suitable dimensions to enable it to be inserted within the sleeve I0, and the top attachment 35 is provided with a similar shank 36 of suitable dimensions to enable it .to be inserted within the inner member It. The attachments are secured by means of a' thumbscrew 37 extending through a hole in the sleeve H1, or in the inner member l3, and engaging a threaded matching hole in the shank 36.

If a support of greater length is desired an extension member can be provided with connections adapted to fit either the bottom of the sleeve H3 or the top of the inner member l3.

'A top attachment adapted to be used in installing overhead batten sockets, is shown in Fig. 6. This attachment comprises a cross member 40 secured to the shank 36, and having a spring clip 4| mounted upon each end, as by wing screw 42 and nut 43. The cross members 40 may be slotted at each end as at 40a to allow the spring clips M to be adjusted as desired. The batten sockets Mi to be installed are fitted over the spring clips 4! and are securely held thereby until permanently fixed to the overhead. When the batten sockets" i l are, permanently fixed, the stanchiorr is lowered and the spring. clips snap. loose.

Another top attachment, adapted to be used in installing overhead berthing hanger hks, is shown in Fig. '7. This attachment comprises a hook receptacle d5 of a width slightly larger. than the hook to be installed. A stop 46 is provided for receiving the end of the hook and for holding the hook in place.

Fig. 8 shows another type of bottom: attachment which is especially adapted to prevent the stanchion from sliding and is also particularly useful in lining up jobs from center punch works on a deck or bulkhead. This attachment comprises a. steel point ll secured to: the shank. portibn2361 Optionally, other types of: bottom and top attachments designed. for: the particular: job at can. be provided Without departing from the principles: of the invention as described and claimed herein,

In operation, the types of attachments are chosen according to'the: nature of the: fittings to be: installed and are placed. in. position upon: the ends or. the stanchion. If the. work is: to: be; done uporr a ship on buildingways, the: declivity wedge T13 is inserted between the; level table; E i; and bracket 22. This is not necessary if the. ship is in dryd'ock'. or otherwise.- resting upon a level keel, or if the stanchion is. to be; used in buildings or other stationary structures; The fittings to be installed? are then placed in or upon the attachments, as for. example the batten sockets 4d upon the spring clips M (Fig. 6).. The stanchion is then placed in approximately the correct position and is adjusted by lifting: on the handle Zil and placing it in the proper notch 52. If the fittin'gheld by the attachment is to be levelled, or if a top fitting is to be aligned with a center punch mark on the deck, the stanchion is levelled by using the levelling attachment iii. The cover member 3''!- is put in place on the level attachment it before overhead work is done. The stanchion supports the work and holds it in place under tension of the spring 19. The fitting can then be permanently secured as by welding or other means, the supporting stanchion allowing the operator the use of both hands in completing the job. The" fitting is thus easily installed in its proper position. The operator will not be subjected: to burningby welding sparks or otherwise inconvenienced due to having to hold the job with one hand.

Various modifications and changes can be made in the devices described above without departing from. the spirit and scope of this invention as set forth in the appended claims,

The invention described herein may be manuiactured and used by or for the Government of the United States for governmental. purposes without the payment of any royalties. thereon or therefor.
