ATTORNEY United States Patent 3,406,728 PORTABLE SAW TABLE AND GUIDE Earl A. Rust, 4955 Fairfax, Fort Worth, Tex. 76116 Filed June 24, 1965, Ser. No. 466,620 2 Claims. (Cl. 143-132) ABSTRACT OF THE DISCLOSURE The invention comprises, in summary, a pair of elongated sections or Work-supporting members having planar surfaces, preferably of light guage sheet metal, such as aluminum, hingedly joined so that one member can be folded upon the other for portability, or storage. Each section of the invention has a frame composed of parallel side elements of square tubular material, and these elements are connected at each end, and at spaced intervals, by cross-members of the same material for proper rigidity. The sheet metal planar surfaces are attached by suitable means to the frames.
The invention is designed to be supported, in use, on a pair of conventional saw horses. Latching means is provided on each side of one of the sections adjacent to the hinge connection engageable by pins arranged on the opposite section to insure rigidity when these members are joined longitudinally. A guide rail is rigidly attached along one side of each section for axial alignment, when the invention is extended for use, against which the work is arranged for cutting. A sliding stop is adjustably attached to the work guide for predetermining the desired lengths of the work materials.
Across one end of the Work-supporting sections is arranged a pair of elements for slidably supporting a portable electric saw. These elements are spaced apart, and adjustable with respect to each other, to accommodate different types of saws.
This invention relates to a portable guide saw table for electric hand saws by which to cut lumber in suitable lengths and to perform mitering cuts.
Objects and purposes A prime object of the invention is that of providing a portable saw table or guide which is light and economical in structure and design, and capable of being operatively supported on common devices, such as conventional saw horses, whereby it is not necessary to provide a supporting frame which would increase the cost of construction and add to the weight of the device without enhancing its usefulness.
Broadly, the invention contemplates the provision of a device as described which advantageously may be formed of various materials and by different methods, as desired, and the structure of which may vary without departing from the invention, which is characterized generally by its sturdy, light weight construction, and is efiicient in operation and durable in use, and may be fabricated inexpensively.
While the foregoing objects are paramount, other and lesser objects will become apparent as the description proceeds, when considered in connection with the appended drawings wherein:
FIGURE 1 is a top plan view showing a device embodying the invention in its operative position, in which its opposite end portions are supported on a pair of conventional saw horses, and showing in broken lines an elongated piece of material, such as a board, supported on the device and adjustably positioned relative thereto preparatory to cutting it in a selected, predetermined length, and showing in broken lines a portable, hand operable 3,406,728 Patented Oct. 22, 1968 power saw slidably supported on the device for cutting engagement with said board.
FIGURE 2 is an elevational view showing the front side thereof.
FIGURE 3 is an end view.
FIGURE 4 is a perspective view showing the device as seen from the top, one side, and one end thereof.
FIGURE 5 is a perspective view on an enlarged scale showing the longitudinally adjustable, removable stop illustrated in FIGURES 1 and 2.
FIGURE 6 is a fragmentary longitudinal sectional view, on andenlarged scale, taken on the line 6-6 of FIGURE 1, an
FIGURE 7 is a longitudinal view showing the front side of the device in its folded position.
Referring to the drawing, the numeral 10 designates generally an elongated, substantially planar supporting device embodying the invention, which advantageously may be of any suitable sturdy, light weight construction.
As shown in FIGURES 1, 2, and 4, the supporting device 10 has its opposite end portions, indicated generally by the numerals 11 and 12, supported on a pair of conventional saw horses, indicated generally by the numerals 13 and 14.
The elongated, planar supporting device 10 has a hinge 15 intermediate its ends whereby it is adapted when not in use to be folded upon itself, about a transverse axis, intermediate its ends, as shown in FIGURE 7, for use in transporting and storing it.
A pair of hooks 16, which are rigidly secured to opposite sides of the end portion 11 and extend beyond its connected end, are engageable over corresponding pins 17 which extend laterally outwardly from opposite sides of the end portion 12, adjacent its connected end, as shown in FIGURES 1, 2, and 4, whereby said opposite end portions 11 and 12 are secured in their longitudinally aligned positions relative to each other.
As shown best in FIGURE 4, the elongated, planar supporting device 10 has a longitudinally extending guide rail 18 along the top side thereof, adjacent one of its longitudinal edges, and has a longitudinally adjustable stop, designated generally by the numeral 19, for abutting engagement with the adjacent side and end surfaces of a piece of material supported thereon, shown in broken lines and indicated by the numeral 20.
The numeral 21 designates generally another stop which is removably and adjustably connected to the guide rail 18. The stop 21 partially encircles and slidably engages the guide rail 18 and is secured in any desired position relative thereto by a set screw 22, and has an abutment 23 thereon for engagement with an adjacent end surface of a piece of material supported on the elongated, planar supporting device 10 such as the material 20.
As shown, the opposite end portions 11 and 12 of the elongated, planar supporting device 10 each have a tubular frame including a pair of longitudinally extending side rails 24 and a plurality of transverse members 25 having their ends connected to the side rails 24. A rectangular plate 26, which like the frames advantageously may be formed of light weight metal, for example, is connected to the top side of each of the frames and form therewith the respective end portions 11 and 12.
The elongated, planar supporting device 10 provides convenient means for supporting and adjustably positioning elongated pieces of various structural materials, as at 20, such material comprising lumber, boards, and the like, preparatory to cutting them in selected predetermined, relatively shorter lengths, as desired, by means of a portable, hand operable power saw, shown in broken lines in FIGURES l, 2 and 4 and indicated generally by the numeral 27.
A pair of elongated slide elements, indicated generally by the numerals 28 and 29, which are relatively shorter than the end portions 11 and 12, are arranged transversely of and above the end portion 11. The slide elements 28 and 29 are supported on two pairs of brackets 30, 31, in vertically spaced relation to the end portion 11 and in spaced apart relation to each other.
The slide elements 28, 29 provide between them a support for sliding engagement by a portable, hand operable power saw, such as the saw 27, adapted to support said saw for cutting engagement with a piece of material, such as the material 20, supported on the elongated, planar supporting member 10.
The slide elements 28, 29 advantageously may be formed of hard wood, for example, and are adjustably spaced relative to each other, by adjustment of the slide element 29 relative to its supporting bracket 31, for use with saws of different makes and models.
The invention may be modified within certain limitations, by persons skilled in the art, without departing from the spirit and intent thereof or the scope of the appended claims.
What is claimed is:
1.
