4 Claims.
This invention relates to an improved Work table supporting structure and in one if its more specific aspects to such a ysupporting structure which is adapted to be advantageously employed with sewing machines.
One of the important objects of this invention is to provide a work table supportnig structure characterized by its light weight, simple design, sturdy construction and attractive appearance.
Another object of the present invention is to provide a work table supporting structure that may be easily and quickly assembled and subsequently dismantled and that may be readily moved from one location to another.
The invention has for another object the provision of a structure of the character indicated that comprises a plurality of certain basic part-s which may be identical and interchangeable and which are therefore capable of being fabricated on a low cost mass production basis.
Another object of this invention is to provide an upwardly extensible work table support that is capable of being readily adjusted in overall height.
A further object of the invention is to provide a support for a -sewing machine table so constructed and arranged as to permit of ready access to a power transmitting unit and other equipment associated with a sewing machine and disposed below the under surface of the table.
A still further object of the invention is to provide a work table leg in the form of an upright generally Z-shaped unit possessing requisite strength and being adjustable in overall height.
The foregoing, as well as other objects, together with the advantages attainable by the practice of this invention, will be readily comprehended by those skilled in the art by reference to the following detailed description taken in conjunction with the annexed drawings which respectively describe and illustrate a preferred embodiment of the invention.
In the drawings:
Figure l is an end elevation view of a work table supporting structure in accordance with the invention and carrying a sewing machine and a power transmitting unit therefor;
Figure 2 is an enlarged bottom View of one of the leg members of the support shown in Figure l;
Figure 3 is a View in perspective of the assembled supporting structure or stand of the invention;
Figure 4 is an enlarged detail view in section taken along line 4-4 of Figure 1; and
Figure 5 is a view in enlargement taken along line 5-5 of Figure 1.
Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, and more particularly to Figures 1 and 3 thereof, I have shown a pair of upright, generally Z-shaped legs L that are maintained in parallel spaced relation by a channel treadle bar IIJ and a channel brace II and that carry a sewing machine table top T which is secured thereto by means of bolts I2, nuts I3 and washers I4. Table top T may. if desired, be of the type disclosed in Fite et al. Patent 2,419,064, dated April 15, 1947, for Sewing ma.- chine table boards, and is provided with a through opening I5 having an oil drip pan I6 which is secured to the table top by screws I1.
A sewing machine frame, generally indicated by numeral I8 and having its base I9 disposed within opening I5, is provided with the usual combined handwheel and pulley at one end. A plate 22 is positioned contiguous the under surface of table top T by means of bolts 23 and nuts 24. Projecting downwardly of plate 22 are a pivotally mounted bolt 25 and a rigid bracket 2B which are respectively pivotally connected at 21 and 28 to frame portions 29 of a power transmitting unit 30. This includes a rotary drive shaft 3l having a drive pulley 32 secured thereto by a nut 33. Rotational movement of drive shaft 3| and drive pulley 32 is transmitted to combined handwheel and pulley 20 through the medium of an open V-belt 34 that extends through a belt slot (not shown), in the table top. The tension in belt 34 may be readily varied in any known manner, such as by adjusting the relative position of pivot 21 along pivot bolt 25 by the manipulation of nuts 35 and 36. It will be observed that by virtue of the Z configuration of leg L, ready access is had to various parts, including bolts 35 and 36 for adjusting the tension in. belt 34, and nut 33 for replacing or repairing drive pulley 32 from the end of the table. In fact, the f entire power transmitting unit is made accessible for repair and regulation. A control rod 31 is pivotally secured in the usual manner at opposite ends to power transmitter 30 and a treadle 38 that is tiltable about a shaft 39 which is carried by a U-bracket 40 adjustably secured to the web of channel treadle bar I 0 through slots 4I by bolts. (not shown).
Each leg L includes an upper member and a, lower member 45 which are preferably identical and which are relatively adjustable as will be more fully explained hereinafter. It is: rec- A'appended claims.
ommended that member 45 be formed of pressed steel to obtain the illustrated channel-like unit, closed at one end 46, open at its other end 41 and having a generally V-shaped web 48. The upper horizontal portion of member 45 is provided with openings 49 for the reception of the top attaching bolts I2. Web portion 48 is provided with a pair of elongated slots and a pair of openings 52. The corresponding parts of member 45 are designated by corresponding primed numerals.
As is best shown in Figures 1 and 3, mem-'- bers 45 and 45 are arranged in relatively inverted relation with their open ends 47 and 41', respectively, facing each other. Extending through open ends 41 and v4T' and telescopically positioned with respect to members 45 and 45 is a channel connector 53 having its outer web surface disposed in abutting relation to the inner surface of webs 48 and 48. The web of channel connector 53 is provided with a plurality of l:elongated slots A54 -so arranged as to register with openings 52 and 52 in webs 48 and'48' for con- 'nectingmembers 45 and 45' to channel 53 and for varying the overall height of leg L through vthe coaction of bolts 55,-and nuts 56. One side nfrthe channel of Veach, connector 53 carries an extension 58 (Figure 3) for connection by means of bolts torthe'opposite ends-of channel brace 'l :l through' suitable apertures not shown) Asa modication ofthe foregoing construction, the channel 'connectors 53 may, -if desired, befsecuredin' fixed and firm relation, as by weldingto either the upper members 45 or the lower members 45'. This provides a somewhat steadier construction". Adequate adjustability as to height may be obtained by the bolt and slot connections between the connectors and the other of the members 45 and 45'.
:As is best shown in Figure 4, each end of ,chan-v nelrtreadle bar I0 is cut out to form a notch 60 that accommodates an upwardly offset portion 6| inthe lower portion of member 45' and is lformed withV an upturned flange 62 appropriately apertured to Areceive bolts 63 which extend through slots 5|.-in the side'facesl of the mem-- bers'45"and carry retaining nuts 64. This arrangement results in asturdy, rigid construction vand permits of horizontal adjustment, l. e., from front to back', of channel treadle bar vI0 with respectto the legs L. The oifset portions 6I of l the lower members '45" andthe corresponding oifsets of the upper members 45 eliminate the full, flat surface engagement of the bottom and top surfaces of themembers with the iloor and :with the table top T, respectively,
Thus,'it will beseen that the construction herein shownand described is well adapted to accom- 'pllsh the objects of the present invention. It willbe understood, however, that the invention may .be embodied otherwise than here shown, and that in the form illustrated certain-changes in construction may be made. Therefore, I do not wishy to" be limited precisely to the construction lherein shown'except as may be required bythe 'Iclamzf l. Apparatus of thecharacter described comprising a' pair of substantially identical 'channellike members, each of said members having a generally V-shaped Web and at least one open end, and a channel extending through the open end of each member and having its outer` web surface disposed in abutting relation to the inner web surface of each member, means for adjustably connecting said channel to each of said members longitudinal of said channel, said members and channel being constructed and arranged to form a rigid upright generally Z-shaped hollow support.
2. In` apparatus of the character described, a pair of supports, each support comprising a pair of substantially identical channel-like members, each of said members having a generally V- shaped web and at least one open end, and a channel extending through the open end of each member and having its outer web surface disposed in abutting relation to the inner web surface of each member, means for ad- ,iustably'connecting said channel to each of `said members longitudinal of said channel, said members and channel being constructed and arranged to forma rigid upright. generally Zshaped hollow unit, and means for maintaining said supports in predetermined vsubstantially parallel spaced relation.
3. A work table comprising' a pair of upwardly extensible, channel-like supports of upright generally. Z.-shaped end configuration, one end of each support being Vclosed and the other end thereof being open, said ysupports being spaced apart horizontally with their open ends facing each other, and means secured to both supports for maintaining the same in said spaced apart relation.
4. In apparatus for supporting a table top above a floor, a pair of substantially horizontally spaced, upwardly extensible, channel-like supports of upright generally Z-shaped conguration, one'end of each support being closed and the other end thereof being open, said supports being arranged with their open ends facing each other, the upper and lower surfaces of said supports being substantially planar and apertured for attachment therethrough to the under surface of the table top and the surface of the door, respectively.
