This invention relates to sewing'machine cabinets of the drophead type having-an apertured top through which the sewing machine headls lowered" when not in use. Cabinets of this type have-a leaf or closure which is adaptad tooverlie the top of. the cabinet and cover the aperture in thetop thereof. i a

One. of the objectsof this invention. is. to pro vide a closure leaf orcoverfor the table-top which is adapted'to slide along the topto an open .position,. and to. provide improved meansfor supporting the-;cover when it isin. open position. Another object of. the inventionlis torso construct the supporting means asto cause it tozautomatn cally become effective. when the cover is in open position, and to automatically. return to its. normal positionwhen the-cover: is moved to its closed position. i

With the above and. other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawing of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

In the drawing- Fig. 1 is a perspective sewing machine cabinet.

Fig. 2 is a top plan view showing the cabinet with the cover in closed position in full lines, and in open position in dotted lines.

Fig. 3 is a sectional view taken along the line 33 of Fig. 2.

Fig. 4 is a side elevation of the cover.

Fig. 5 is a sectional view taken along the line 55 of Fig.2.

Fig. 6 is a sectional view taken along the line 5-6 of Fig. 2 and showing the channel guide member for the cover.

In the embodiment of the invention selected for illustration the improved cabinet comprises the legs l0 and II connected at their lower ends and at the rear edge thereof by a transversely arranged foot-board l2. Supported at the upper ends of the legs is a top l3, apertured as at M, to receive the head of a sewing machine. Located below the top l3 and connecting the legs l0 and II are front and back side pieces 15 and I6, respectively, the front piece I5 being provided with a pivoted drawer II. The top portion of the legs I0 and H and the side pieces l5 and [6 form an enclosure which houses the sewing machine when it is lowered.

view of my improved Slidabl mounted. on the top I3: is. a. cover or lea! [shaving downtumed sida walls 9. andran end walli 20. Secured by screws to. the under side of the leaf [8 and to the side-walls l9; and located at each of the corners onthe right en of the leaf l8, as viewedinll'is; 2; is a u-shaped channel g ide member 2 l; with its lower limb underlyingthe marginal edge of. the tabla-top 3. Also located on the under side and at the o her twocorners of. the leaf l8. and secured by screws tO-the, side Walls lfltandi end wa1l.2n.are two L... shapedsheet metal guides 22 having their lower limbs underlying the lower margin l edge or the table-top 13. From the above it will boomer-void that the guide members 2| and 2 hold th lea on thetable top so that thaentiro tablermay' be lifted. by the leaf. Also the guide members 2| guide the leaf when it is being moved to open position, as shown-in Fig, 1. Further, when the leaf is in open position the guide members 2| serve to partially support the leaf. To stop the leaf in its proper position a screw 23 is placed on the under side of the top near the marginal edge and at the left-hand end of the top. When the leaf reaches its correct open position the lower limb of the guide 2| strikes the screw 23 and the leaf is thereby prevented from being pulled from the table-top.

.In order to assist in the support of the table leaf when it is in open position the leg I0 is provided with a cut-out 25 (Fig. 3) in which is located an arm 26 pivoted intermediate its end on a pin 21 having its lower end extending into the leg in and its upper end secured to the top [3 by means of a sheet metal plate 28. The arm 26 is provided at one end with a cylindrical upstanding portion 29 the top of which engages the lower face of the leaf I8. Near the other end of the arm there is secured one end of a tension spring 38, the other end of the spring being secured to the under side of the table-top I 3. The spring 30 biases the arm 26 so that it tends to swing about its pivot to its leaf-supporting position as shown in dotted lines in Fig. 2. To limit the movement of the arm 26 about its pivot a lip is struck from the sheet-metal plate 28 to form a stop 32 which is adapted to be engaged by the side of the arm 26 when the arm has reached its correct leaf-supporting position. In order to return the arm 26 to its normal position and to align it with the leg Hi the under side of the leaf I8 is provided with a rectangularly shaped block 33. When the leaf is pushed to closed position to cover the top of the table, the end Wall 20 initially engages the cylindrical end 29 of the supporting arm 26 and forces the arm 26 to swing about its pivot until the leaf near its closed position at which time the block 33 engages the side of the arm and pushes it to a position in which it is flush with the leg Ill. In this position the arm 26 is in contact with the metal strengthening members 34 and 35 which bridge the cut-out 25 and connect the leg Ill and top l3. To permit the block to force the arm 26 to a position in which it engages the members 34 and 35 the table-top I3 is formed with a cut-out 36 which is complemental to the block.

From the foregoing it will be observed that the leaf I8 is adapted to slide along the table-top tion what we claim herein is:

l. A sewing machine table of the drop-head type having legs and a rectangularly shaped top carried thereby, an extension leaf having side walls and an end-wall extending downwardly over the edges of said table-top, guide members secured to and located on the under side of and at the corners of said extension leaf, said guide members extending beneath the lower marginal edge of said top and adapted to slidably secure said extension leaf to said top, a leaf-supporting arm pivotally carried by said table, a spring for moving said arm to its leaf-supporting position when the extension leaf is moved to its open position and means carried by said arm and en-- gageable by the end wall of said extension leaf for moving said arm to its non-supporting position, in opposition to said spring, when the extension leaf is moved to its closed position.

2. A sewing machine table of the drop-head type having legs and a rectangularly shaped top carried thereby, an extension leaf having side walls and an end-wall extending downwardly over the edges of said table-top, sheet metal guide members secured to and located on the under side of and at the corners of said extension leaf, said guide members extending beneath the lower marginal edge of said top and adapted to slidably secure said extension leaf to said top, a leafsupporting arm pivotally carried by said table, a

' spring for swinging said arm about its pivot to its leaf-supporting position when the extension leaf is moved to open position, a stop for limiting the movement of said arm about its pivot, and means carried by said arm and engageable with said leaf for moving said arm to its normal position when the leaf is moved to its closed position. I i

-3. A sewing machine table of the drop-head type. having a rectangularly shaped top supported by legs located at each end of'the top, an extension leaf mounted for sliding movement on said top, a leaf-supporting arm located in a cut-out in one of the legs and pivotally secured to said 'leg,"a tension spring having one of its ends secured to said table top and its other end secured to said arm, said spring tending to move said arm about its pivot to a leaf supporting position when said leaf is extended, and a depending member carried by said, leaf for engaging said arm, returning it to non-supporting position when said leaf is retracted, and maintaining it in said outout against the action of said spring,
