PORTABLE UNIVERSAL SAW TABLE
BACKGROUND OF THE INVENTION
This invention deals with a portable saw table which can be used for cross cutting lumber and other items. My U.S. Pat. No. 5.144.994 issued Sep. 8. 1992 entitled Portable Universal Saw Table, discloses a structure for a saw table which, although is very useful and is portable, cannot be folded up to reduce it to a more easily carried size. Since it is desirable to have tables of this sort and related tables available for easy movement. I have developed a different structure which provides for easy folding for carrying purposes.
SUMMARY OF THE INVENTION
The portable universal saw table of this application is used mainly for cross cutting lumber pieces such as boards, trim, moldings, siding and the like. The table includes two rails which can be mounted in parallel relationship and held there by cross pieces. The cross pieces are designed to be hinged to the rails so that the rails can be folded toward each other to provide a very neat portable package. As is done in my above referred to patent, wooden cross pieces are provided which are fit into notches in the rails. The rails themselves may be made of metal or wood, although metal is more preferred. The table is also provided with a wooden fence member which is used to locate the piece to be cut so that it can be precisely measured and severed at the point desirable for use. The rails also include extension members to increase the length of the table so as to accommodate longer pieces of lumber.
The table of this invention is also provided with removable material racks which can hold the pieces of lumber that are to be cut in an out of the way position, but readily available for use. These material racks are removable and can be placed along side the folded rail construction of the table so that they can also be easily carried.
The portable table is provided with leg sockets so that legs of the desired length can be cut on the job and inserted into the sockets to locate the table at the proper height for use. The cross pieces are generally 2x6 cross members which may be cut to the proper length and be fitted into the table.
A saw platform is also provided on the table so that a rotary saw may be positioned for cutting the various pieces of lumber.
Other advantages of the saw table of this invention will become apparent from the description thereof and the accompanying drawings.

DESCRIPTION OF THE PREFERRED
The portable universal saw table 1© is composed of the rails 12 which may be of metal or wood but preferably metal
5 which form the basis of the saw table. There are a pair of the rails 12 which are preferably tubular and of rectangular cross section and connected to each other by cross pieces 20 which are hingedly attached at 16 by bolts, rivets or the like. This construction allows the rails 12 to move parallel to each
10 other so that they may be folded into a compact package. The rails 12 include notches 18 in the top and facing sides of the tubular rails. These notches are designed to hold cross pieces 20 that keep the rails in an open spaced-apart condition. The cross pieces 20, as will be explained later, may
15 be cut from lumber on the job. The cross pieces or support pieces 20 are generally cut from 2x6 lumber to the desired length and then fitted into the notches 18. The support pieces 20 are supported on the notch defining portions of the rails and extend above the rails 12 so that the work pieces to be
20 cut travel along the top surface 20a of the support pieces. The ends of the support pieces abut other notch denning portions of the rails 12 and thus keep the rails in their fully spaced apart condition.
25 Sockets 30 are provided on the underside of the moveable pair of rails. These sockets 30 are designed to receive the legs for the portable table. Legs 24 may be and preferably are cut from lumber on the job to the desired height. They are fit into the sockets 30. They are held there by the set
„„ screws 26.
The pair of rails include extension rails 28 which telescope therein. These extension rails 28 are designed to be extended to enlarge the surface of the portable table. At the end of each of the rails is a socket 28a similar to the notches
35 18 in the rails 12. These opposing sockets 28a are designed to receive a support piece 20. and each of these end support pieces may be held in place in the sockets 28a of the extension rails by the set screws 282>. A saw platform 32 is provided for holding the portable
40 rotary saw to be used with the saw table of this invention. The saw platform 32 is held in place by brackets 34 and may be located at any desirable height by moving the brackets up or down on the support pieces 20. The brackets are held in place by screws not shown. A conventional rotary saw 36 is
45 located on the saw platform 32 so that it may be used to cut the lumber in front of it. The saw shown is a standard hand manipulated electrical circular saw. This could also be a table saw. in which case the saw platform 32 would be the table for the saw and this would be held in place by brackets
It may also be desired to have a suitable guide for the saw 36. Such a guide could be fashioned by having wooden pieces attached to the top of and spanning the space between the crosspieces 20 on either side of the saw and a pair of
55 angle bars extending parallel to the cross pieces and spaced to guide the movement of the saw.
Also, if desired, a pair of 2x4's could be attached to the opposite ends of the 2x6 cross pieces 20 above the rails 12, forming a sort of wooden ladder. A stop in the form of a
60 wooden piece or angle bar could then be attached across the 2x4 at a suitable location to form a guide for cutting large pieces of plywood, for example.
A fence member 38 is provided as a back stop for the lumber to be cut so that it can be held in place, measured
65 properly and cut at the proper point. The fence member 38 is secured to the tops of the support pieces 20 by L-brackets 38a and screws 38f> (see FIG. 6) and are cut at 38c (see FIG.
