SEWING-MACHINE TABLE.

SPECIFICATION forming part of Letters Patent No. 571,748, dated November 24, 1896.

Application filed August 17, 1896. Serial No. 602,938. {No model.

To rfi/"ZI H'lfo'nt it 71mg/ concern.:

le it known that I, JOHN COCHRAN, a citizen of the United States, residing at Ripley, in the county of Brown and State of Ohio, have invented certa-in new and useful lmprovenients in Seiving-3Iael1ine Tables; and l do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form a part ol' this speciiication.

My invention comprises a number ot' novel features in the construction of those tables or stands which have drop leaves or platforms for supporting sewingunachines, type-writin g machines, dc., the details ol:l said improvements being hereinafter more fully described and then pointed out in the claims.

ln the annexed drawings, Figure l is a front elevation of my improved drop-leaf table arranged for the support of a sewing-machine, the table being shown in its closed position. Fig. l is a rear elevation ol the same. Fig. 3 is a front elevation showing said table in its open position and the sewing-machine exe Fig. l is a horizontal section through the upper part of the closed table. Fig. 5 is a vertical section of the closed table, taken at the line Z Z of Fig. 7. Fig. G is a similar sec tion of said table, taken at the line Z Z ol' Fig. '7. Fig. 7 is a plan of the under side oi' the table, a false front thereof being omitted and portions of the framework sectioned. F i'. S is an enlarged vertical section of one D I n of a pair of adjustable keepers secured to the underside oi a lralne attached to the table. Fig. 9 is an enlarged horizontal section of one oi a pair ol recessed brackets secured to the table'front. Fig. l0 is a vertical section of said bracket. Fig. ll is a plan of a portion et' the above-mentioned frame, to which a peeulia rly-constructed tu rn-button is to be applied, the position of said button being indicated by dotted lines. Fig. l2 is a vertical section through said button.

My stand or table proper, A, is ol any de sired size, shape, and material and has an opening a, as seen in Figs. i, 5, and 6, to permit a free swing of a drop-leaf, and in addition to this opening said table has a pair of end `pieces or cabinets d' a for containing sliding d rawers or other similar con veniences. Secured to this table and rigidly connected to said end pieces o.' o" are brackets B l', having recesses h h' on their inner sides, as more clearly seen in Fig. 7 the recesses being eoncaved horizontally, as represented in Fig. 9. Furthermore, said recesses slope outwardly from bottom. to top, as shown in Fig. l0, tor a purpose that will soon appear.

B" is a transom-strip rigidly secured both to the. table A and brackets B B' and serving to conceal certain operative parts of the table as soon as it is opened.

C O are side wings hinged at c c to the end pieces o." a" and extending up slightly above the lower edge of transom B", as indicated by dotted lines in Fig. l.

D isa false front somewhat wider than the opening between the closed wings C C and reaching from the transom ll" down as far as may be necessary to conceal the drop-leaf and its attachments.

F. E are cleats secured to the ends of this front D, the foremost portions of said cleats being rigidly attached to the under side of a drop-leaf F, which leaf is hinged to the tablef rame at ff', as seen in Fig. 7, and is adapted to swing up and down through the opening dof said table.

c c are rods so connected to the cleats E E and drop-leal'l F as to cause the members D F of the table to preserve their proper angular position with reference to each other, the angle being more clearly seen in Fig. C.

The exact inclination at which the fronti) is rigidly applied to the hinged leaf F is immaterial, provided the angle is such as to render said 'front substantially vertical when said leal. is swung down far enough to conceal the head of a sewing-machine underneath the table-lid. (See Fig. 5.) Again, this inclination must be such as to cause said front to remain about at the angle seen in Fig. 0 when leaf F is swung up to a horizontal position.

Secured to the under side of drop-leaf F is a pan G to catch oil or other drippings from any machine carried by said leaf. In the present case, however, a sewing-machine head H is mounted upon said leaf and is driven by a band 7i, passing around a pulley of said head and communicating with a Hywheel housed within a guard or shield, a portion of which is shown atlin Figs. l, 2, and 3.

IOO

'y g in Fig. 7 are slots in the leaf F to permit a free passage of the drivingeband, and g in Fig. 5 is a bent wire loop that retains said band in the position shown when the yhead Il is dropped down out of sight. rThe ends of this loop are attached tothe cleat E. f

rPivoted at j to the under side of the leaf F is a lever J, from which a rod K extends rearward and engages with a catch L, pivoted to said leaf at 7,.

lll is a keeper (see Figs. 0 and S) secured to the under side of the table-frame P and adapted to have the catch L automatically engage therewith.

L is another catch pivoted to the leaf at Z and ycapable of automatic engagement Withar keeper M.

m is a pushin g-sprin g that insures a prompt and simultaneous engagement of said catches With their respective keepers, the peculiar construction of the latter being seen in Fig. S. f Reference to this illustration shows that the front end of the keeper is fastened to the table-f rame P at O, is perforated vertically at o, and has a screw o passed through another hole and then engaged with said frame.

o is an adjusting-screw in line With the perforation o and engaged with said frame. The head of this screw o is larger in diarneter than said perforation and bears against the upper side of the keeper. Consequently, by passing a small tool up through the hole o and then turning the sere1 o", the keeper M can be so adjusted with reference to the frame aste permit a ready engagement of the catch L with said keeper, and thereby bring the upper surface of the drop-leaf flush with the top of said frame. After this adjustment has been elfected the screw o is tightened, so as to retain the keeper in ils properposition, but enabling it to be reset at any time in case the Wear and tearof the machine should cause the upper surface of the leaf F to settle down below the level of the table frame. This frame P is secured upon the table and surrounds thc drop-leaf F When it is swung up to a horizontal position, one end of said frame having hinged to it at 2) an extension-top p', capable of being opened to the position seen in 3 previous to using any machine mounted upon said leaf.

Q. is a flexible screen whose upper edge is secured to the under side of the table A, while its lower margin is attached tothe rear of leaf F, the screen being sufficiently long to reach from one end piece a to the other piece a, and thus close the entire rear space bctw'een said pieces a' a, as seen in Fig.

R R' are rods projecting from the upper portions of wings C C/ and adapted to be operated by workers S S. These Wing-Workers a re usually made of double Wires having their fixed ends secured to the leaf F, as at s s', while their front or free ends are formed into loops s", as more clearly seen in Figs. 7, f), and lO.

T T are braces fastened to said leaf and capable of being so adjusted as to regulate the forward and backward movements of the Wings C C' and keep the Workers S S' in line with the rods R R of said Wings. Each brace is composed of a piece of Wire so bent as :o afford a slot through which is passed a screuv that fastens said Wire to the leaf, the ends or' the braces nearest the pieces a a" of the table being secured to the Wing-Workers S S'.

U in Figs. ll and 12 is a groove in the frame P, and V V are thefside Wires of a spring inserted Within said groove, the free end of said spring being formed into an u pward bend or arch c. The fixed ends of these wires are bentdown and driven into the frame P on opposite sides of a screw NV, that serves as a pivot for a turn-button X. rFhis button can be swung around, either to the right or left, and has on its under side a countersink ai, Wherewith is normally engaged the arch above referred to.

ct is a lip projecting ylaterally from said turn-button and adapted to engage over the bed-plate of any machine applied to the dronleaf F. (See Fig. 5.)

Y 'is part of a low-down metal frame forming the bottom portion of the support for the stand or table and its cabinets or other emi pieces. f

q is a slat extending from end to end of the screen Q for the purpose of distending it anu causing a snug fit against the innersides ir the end pieces or cabinet-frames CL d.

The normal positions of the various parts of my drop-leaf table are seen in Figs. l, J. and 5, reference to which illustrations shows that the extension-top P is now closed upon the frame P, and thus serves as a cover for concealing the machine-head ll and all attachments ofthe same. Again, thewiugs t' C' are now shut up snugly against the rear of brackets B B', which brackets stop and rigidly hold said Wings in the position seen in Fig. it. Consequently these Wings form a rigid stop or bearing for the false front D, drop-leaf F, and the machine carried nv said leaf, the front being vertical and closed against the Win gs on account of it being rigid iv secured to said leaf by the cleats E E and connecting-rods c c. In this position of the parts the weight of the machine ll is transferred to the front D by means of the rods c d, that connect said front to the drop-leaf. Furthermore, the free or effective ends of the Wing-workers S S are noiv run up to the top of recesses l) b', as seen in Fig. lO, the rods R R' being loosely. confined between the double Wires constituting each uorker and the screen Q being down, so as to close the entire rear space extending from one end piece, a', to the other piece, a. Consequently all the drop appliances and the drop attachments are now concealed and protected. and the table can be used as an ordinary stand; but when it is desired to operate the sewing-machine the extension-top P is first swung over to the left, as seen in Fig. 3.

The ope ators hand is then passed down through the frame P and opening a, and the arm of the machine is grasped and pulled up, the result being to swing the drop-leaf F on its hinges, and thus raise said leaf until its upper surface is flush with the top of said frame, at which moment the catches L L' automatically engage with their respective keepers lll lil'. Hence it is evident the leaf is stopped by the catches L L' and by them and their keepers is automatically locked in the horizontal position seen in Fig. G,

During the lirst part of the upward swing of the leaf F the looped ends s" of the wingworkers travel down theinclined sides ofthe recesses l) b', but do not operate the wings G C because the openings between the double wires S S are directly in line with the rods R R' of said wings; but as soon as the leaf has been raised high enough to bring `these loops s" in contact with the rods the pull against the latter becomes positive and throws the wings (l C wide open, as seen in Figs. 3 and G, and causes said wings to bear against the inner sides of the end pieces a' a of the table. (See dotted lines in Figs. 4: and 7.) lu this open position of the table unobstructed access is alliorded to the treadle and other parts of the driving mechanism of the sewingmachine because the front D is raised quite high and its lower edge is so far back as not to interfere with the knees of the operator. Again, the screen Q is now doubled back on itself and hangs but very limited distance below the rear edge of said front. Therefore my table or stand, is especially adapted for those sewing-machines which require access to their operative parts under a table while said machines are raised on their dropdeaves. To close the machine, the operators hand is placed under the table andlevor .l is grasped and pulled forward, as indicated by the arrow in Fig. 7, which act simultaneously disengages the catches L L' from their keepers M lil' and allows the leaf F to be lowered. rlhis lowering or drop movement restores the wings C C', iront D, and screen Q to their normal positions and again conceals the head l'I as soon as the extension-top P' is closed. Then leaf F commences its downward swing, the rods R R' occupy the bends s" of the wingworkers, as seen in Fig. 7, and on this account the wings C C partake of the closing movement of said leaf, as represented in Fig. Q; but as soon as said win are completely closed the continued swing of the leaf .brings the the workers S S in contact with the beveled sides of the recesses l) b', and thereby forces the bends s away from the rods R R', thereby stopping their action on the wings. As the leaf swings down still farther the free ends of `the workers run up within the recesses, and by the time said leaf has been lowered as far as it can go the loops s" of the said workers will be at the top oi said recesses, as seen in Fig. li).

From the above description it is evident the workers S S' grasp the rods R R' only so long as it is necessary to open and close the wings, and for this reason said wings travel but a very limited distance, while the swing of the drop-leaf is relatively much greater.

The turn-button (more clearly seen in Figs. ll and l2) is another advantage peculiar to my table, as it enables the ready and very secure attachment thereto of the head H or other piece of machinery and facilitates its convenient disengagement.

Normally the bend o of the double spring V V occupies the countersink .t of the button, thereby lookin g the latter and causing its lip .50' to engage over the edge of the bed-plate of the machine. To detach the machine, it is necessary only to exert a slight force against said lip, so as to turn the button either to the right or left, at which time the pressure against the bend c will wedge the spring down within the recess U. The button can then be turned with the greatest facility, but as soon as it is restored to its normal position the automatic upward spring of the wires V V causes their connecting bend n to again engage with the countersink cc and lock said button.

I claim as my inventionl. The combination of a table or frame 5 a leaf hinged thereto; a front secured angu larly to said leaf 5 end pieces projecting down from said table 3 wings hinged to said end pieces, and devices that communicate mo tion from said leaf to said wings, for the purpose stated.
