WORK-BENCH.

Specification of Letters Patent.

Application filed. December 8, 1916. Serial N 0. 135,895.

To all whom it may concern:

Be it known that I, ELIAS W. HOWELL, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Work-Benches, of which the following is a specification.

'My invention consists of an improved work bench or supporting structure. includ ing adjustable clamping means which renders it especially useful for carpenters and metal workers. However, it can be used advantageously for any purpose where it is desired to firmly clamp and support articles of various types. I

One object of my invention is to provide a supporting structure including clamping means which can be quickly and easily operated to positively secure pieces of wood, metal, or other articles so that they can be planed, sawed, or otherwise operated upon.

by one or more persons.

Another object is to so form my invention that it will be of simple construction and can be manufactured and sold at reasonably low cost.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a perspective view representing my invention constructed in the form of a carpenters or workmans bench.

Fig. 2 is a slightly enlarged section taken I on the line aa of Fig. 1.

Fig. 3 is a fragmentary section on a larger scale than shown in Fig. 2 and having a portion brokenaway in order to show in'detail certain of the elements shown in' the upper portion of Fig. 2. V v

Fig. a is an enlarged fragmentary section taken on the line Z/b of Fig. 1.

5'is an enlarged fragmentary section taken on the line 0 0 of Fig. 1.

Fig. 6 is an enlarged transverse 'sectlon taken on the line 0Zd of Fig. 1. r

Fig. 7 is an enlarged section takenon the the line ee of Fig. 1. 1 'Fig. 8 is a perspective view of a readily removable clampingvsection which I employ.

Fig. 9 is a perspective view of a toothed jawwhich I use in connection wlth a vise show'nin Fig. 1.

Fig. 10 is an enlarged sectionalview taken on the line ff of Fig. 1.

Fig. 11' is a fragmentary section showing a modified form ofadjusting means'which I may employ.

Referringto the drawings, 1=is a sup. portlng frame having legs 2, which are connected by longitudinal beams 3 and transverse beams 4 at the bottom, and longitudinal beams 5 and transverse beams 6 at the top. These legs and beams are preferably secured by bolts 7 so as to form a rigid sup porting frame. 1 7

To the outside of the legs 2 and upper Patented Aug. 7,1917;

beams 5 and6, are secured end boards 8 and side boards 9. One of the side boards 9,

which as illustrated represents the front of the bench, comprises a plurality of continuous strips 10 which are tongued and grooved in! the ordinary manner of floor boards.

These boards are secured to the frontlegs 2 and are spaced apart to receive two series of sliclable sections 11. the exception of clamp-carrying sections 12,

are tongued and grooved on opposite sides to I register with the tongue and grooves of the These sections, with 7 adjacent strips between which they slide, so 7 that the sections 11 will move longitudinally between the strips 10, but cannot be removed laterally. In other words,-in order to remove these sections it is necessary to slide them to one end of. the bench soas to pull them longitudinally out of the grooves.

The ends of the sections 11 are grooved as shown at 13in Fig. 10 to receive end tenons 14 which arelocated at the opposite ends of the sections 12. The sections 12 are provided with clamps 12 including a hinged clamping plate 15. Theseclamps when not 1 m use, are movable into recesses 16 by means of adjusting screws 17, so that their outer surface is flush with the outer surface of said sections.

Each of the plates 15 is movable outwardly by a spring 15* when the'adjusting screw 17 is loosened (see Fig.10). These sections-12are interchangeable with any of the sections 11 and are movable relatively toward each other between the strips 10 by clamp screws as will hereinafter be set forth.

The top' ofthe bench comprises a plurality of boards or strips 18 which' are secured to I the beams 6 by any suitable means and are,

spaced apart. These boards 18 are tongued;

ing block 29 through which passes a and, grooved in a manner similar to the strips 10, and have slidable between them, a plurality of series of slidable sections 19, said sections 11 above described.

Inter-posed between the ends of the sections 19, are sections 20 which are similar to the sections 12 and are provided with hinged clamping plates 21 which are designed when not in use to fit within recesses 22, each of said clamping plates being movable out-. 'wardly by a coiled spring 23 and movable inwardly by an adjusting screw 24.

The sections 11 and the sections 19 serve as filling pieces. Sections 25 and 26 are secured to the frame adjacent one end of the bench and act as thrust members to limit the sliding movement of said sections in one direction.

A section 27 is provided with a clamp 28 similar to the clamp 12 and has a dependplain portion 30 of a clamping screw 31. This screw is permitted to turn within said block, but longitudinal movement relative thereto is prevented by means of a head 32 on said clamping screw, and a pin 33 which is projected therethrough and engages the inner surface 34 of the block 29, said head 32 engaging the outer surface of said block.

A handle 35 slidably engages the head 32 and facilitates the turning of said screw 31.

A plate 36 constitute a nut and has a thread ed opening which is engaged by the screw 31. This plate 36 is secured within the end board as clearly shown in Fig. 5, and it will be understood that a turning of said screw effects a longitudinal sliding movement of the section 27 toward or from the other sections which are in line with said section 27.

It will be noted that there is a plate 36 5 directly below each of the spaces between the boards 18 and also there is a plate 36 directly adjacent the spaces between the strips 10 in the front of the bench, so that said section 27 may engage between any of the spaces provided by the boards 18 or the strips 10, and in each case the clamping screw 31 will engage the tapped opening of a respective plate 36.

Any of the sections 12 or 20 may be re moved by giving them an upward tilting will be noted that instead of providing the movement as shown in dot-and-dash lines in Fig. 6 after adjacent filling pieces have been moved longitudinally a sufficient distance to free the end tenons of said sections, since it regular groove on one of the edges of the sections 12 or 20, as is provided in the sec tions 11 or 19, said edge of either of the sections 12 and 20 merely has a flange 37 7 (see Fig. 6), so that it maybe raised and readily removed. This construction prevents the necessity of movlng all of the sections out of the spaces in orderjto remove 19 being similar to the sections oneof the clamp sections 12 or 20, since it will be noted that it'is often desirable to move said clamp sections to different positions in order to suit and bind different sized objects. V V

' The clamp section 27 has its hinged clamp plate pointing in a direction opposite to the hinged clamp plates of the sections 12 and 20 as illustrated, so that a piece of wood or other article -may be bound between the clamp on the section 27 and clamps on any of the sections 12 or 20.

All of said sections as above mentioned may be made of wood, but I have also illustrated two series of metallic sections 38 and 39 which are arranged respectively on the top and front side of the bench adjacent the edge 40 thereof. These series 38 and 39 comprise filling sections 41 and 42 respectively which are similar in all respects except size, with the sections 19 and 11 respectively.

I have also illustrated a clamping section 43 in said series 38 and have provided the same with clamps 44 and 45. The clamp 44 extends in the direction of said series, while the clamp 45 extends transversely.

The sections 41 and 42 are in tongue and groove connection with inserted tongue and grooved rails 46 which are spaced apart and secured to the top and front of the bench. An active slidable section 47 is provided with a clamp 48 which is substantially the same as the clamp 12 and has a. depending portion 49 designed to receive a plain portion 50 of a clamping screw 51. This depending portion 49 is confined between a head 52 and a pin 53 on said clamping screw. A plate 54 forms a nut and has a threaded opening in which the clamping screw 51 turns.

A handle 55 is slidably secured within the head 52 and serves to facilitate the turning of the screw 51. It will be noted that with this construction that the section 47 receives a longitudinal movement between the rails 46 to move its clamp toward or from the clamp 44. The threaded opening in the plate 54 is so located with respect to the two series 38 and 39 of movable sections that the section 47 may be moved to actuate either' of said series 38 or 39, so that said clamping screw 51 may always operate within the plate 54.

I also provide a vise 56 and a jaw 57 having a toothed edge 58, said jaw being substantially L-shape and having bolt slots 59 so as to permit it to be adjustably secured to the top of said vise 56. I also preferably provide a clamp 60 on the top of the bench opposite the aw 57 so that ma- R edge 62 of the bench have blocks 63" provided with lateral ribs 64 which slide within the grooves of said recesses 61.

Each of the blocks 63 carries aclamp of similar construction to the clamp 12 and has a depending nut 65 which is engaged by the threaded end 66 of atransversely extending bar 67, the latter extending entirely across the bench and having a winged head 68 which engages the outer surfaces of either of two recessed plates 69 which are set in the front of the bench as clearly shown in Figs. 1 and 3. a I

A pin 70 extends through the bar 67 and engages the rear surface of said plates 69 to prevent longitudinal movement of the bar 67 when turned; however, it will be noted that a turning movement of said bar causes a relative slidingmovement of the block 63 within either of the recesses 61, and I preferably mount clamps 71 on the upper surface of thetable in direct alinement with the path of movement of the block 63'within either of the recesses 61.

I have illustrated two recesses 61, but it will be noted that any number of these recesses and any number of plates 69 may be provided according to the length of the bench. With this construction it will be noted that apiece of'wood or other article may be clamped between the clamps 71 and the clamp which is carriedby the'block 63.

While I have described and illustrated a specific number of the slidable sections having pivoted clamping plates therein, it will be noted that a greater or smaller number of these sections may be employed and interchanged at will.

Furthermore, the specific form of section clamps which I have illustrated and described may be varied, but I prefer to use a clamp having a portion which may be movable beyond the surface of the bench when needed for use and which can be moved either flush or below the surface of the bench when not in use so as not to. injure or inter- V fere with the manipulation of articles over the bench.

It will be noted from Fig. 1 that the clamp 45 on the section 43 may also be used in connection with the clamp on the block 63 to secure an article to the supporting structure.

In Fig. 11, instead of having a flat plate as shown at 36 and 5A in the other figures of said drawing, I employ a nut 72 which has flanges or cars 7 3 which are secured in the recesses formed in the inner surface of the end board 8. This gives a long screwthreaded contact portion for the clamp screw and is desirable when my invention is used for heavy work. In all other respects the elements illustrated in Fig. 11 are similar to those illustrated in Fig. 5, and I have given the same reference numerals. V

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without'departing from the spirit thereof, and hence I do not limit my self. to the precise construction set forth, but consider that I am at liberty to make such changes and'alterations as fairly come, within the scope of the appended claims.
