SEWING-MACHINE TABLE.

Specification of Letters Patent.

Patented Nov. 8, 1910.

To all whom it may concern:

Be it known that we, THEODOR KUNDTZ, a citizen of the United States of America, residing at Lakewood, in the county of Cuyahoga and State of Ohio, and ALBERT SoHUs- TER, a citizen of the United States of America, and residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sewing-Machine Tables; and we do hereby declare the following to be a full, clear, and exact description of the invention,

. such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in sewingmachine tables.

One object of this invention is to provide the stationary portion of the sewingma chine table with a movable leg or stand for carrying the driving-wheel and treadle, which stand is in an upright position and rests on the floor or is raised off the floor according as the stand is at the one or the other extremity of its range of movement, and to provide such an arrangement of parts that the driving-wheel is in an operative position in the upright position of the stand, and the treadle of the stand when the latter has been raised off the floor is out of the way of a broom or other means employed in sweeping or cleaning below the table and no removal of the treadle from the stand nor any disconnection of the pitman from the treadle and driving-wheel are required preparatory to the actuation of the stand from its upright into its raised position.

Another object is to render the treadle capable of being swung toward the drivingwheel preparatory to the actuation of the driving-wheelbearing stand from its standing into its elevated position.

Another object is to not only provide the top of the table with an opening which is arranged to be occupied by the platform employed in carrying the sewing-machine head, which fplatform is supported to render it capable o lowering the sewing-machinehead below the table-top or raising the said head above the table-top, and to provide the table-top with a leaf which is supported to render it capable of swinging in a vertical plane and covers the aforesaid opening when the platform is lowered and forms a leftward extension of the table-top when the platform is in its opening-occupying position, but to operat-ively connect the driving wheel-bearing stand with the said leaf in such a manner that the said stand is in its upright position and rests on the floor or is in its raised position according as the leaf is in its opening-covering position or in its top-eXtension-forming position.

Another object is to provide the sewingmachine table with a driving-wheel-bearing stand which is pivotally supported at its upper end below the right-hand end of the platform-receiving opening in the table-top and arranged to render the said stand capable of being swung upwardly toward the platform.

Another object is to operatively connect the said platform with the driving-wheelbearing stand in such a manner that the platform is actuated from its lower position into its opening occupying position during the actuation of the said stand from its raised into its standing position.

Another object is to permit the lowering of the platform by gravity during the actuation of the drivingwheel-bearing stand from its standing into its raised position and to actuate the platform into its openingoccupying position by and during the move ment of the said stand from its elevated into its standing position.

Another object is to provide the stationary port-ion of the table with a laterally movable bracket which is in position under the left-hand end-portion of the table-top in the opening-covering position of the aforesaid leaf and held in the said position by means which are rendered inoperative during the shifting of the treadle from its elevated into its lower position, and to provide means acting to move the said bracket laterally and outwardly in under the said leaf when the latter has been actuated into its top-extension-forming position so as to support the said leaf in the last-mentioned position.

With these objects in view, and to the end of rendering the construction simple, convenient and reliable, and to realize other advantages hereinafter appearing, this invention consists in certain structural features, and combinations and arrangements of parts, hereinafter described, pointed out in the claims, and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a front view of a sewing-machine table embodying our invention, and shows the table ready for use as a sewing-machine table. Portions are broken away in this figure to reduce the size of the drawing and to more clearly show certain features of construction. Fig. 2 is a horizontal section on line 22, Fig. 1, looking downwardly. Fig. 8 is a top plan relative to Fig. 1. Fig. at is a vertical section on line H, Fig. 1, looking in the direction indicated by the arrow. Fig. 5 is a front view of the sewing-machinetable and shows the pivotally supported stand which bears the driving-wheel and treadle swung upwardly toward the platform. Fig. 6 is a vertical section on line 6-6, Fig. 5, looking in the direction indicated by the arrow, except that in Fig. 6 the lever-mechanism establishing operative connection between the driving-wheel-bearing stand and the leaf which covers the opening in the table-top in the elevated position of the said stand is shown in elevation. Fig. 7 is a horizontal section on line 7-'(', Fig. 5, looking downwardly. Fig. 8 is a vertical section on line 88, Fig. 1, looking in the direction indicated by the arrow. Fig. 9 is a section in detail illustrating the engagement by the treadle-bearing portion of the driving-wheelbearing stand, during the movement of the said frame from its upper into its lower and standing position, with the arm 14 of a latch which is rendered inoperative during the said movement. Fig. 10 is a section, in detail, on line 1010, Fig. 9. Figs. 9 and 10 are drawn on a larger scale than the preceding figures.

Referring to the drawings, A indicates the stationary top of our improved sewing-machine table, and B the legs of the table. The top A and legs B form members of the stationary portion of the table. The said stationary portion of the table also comprises a back C which extends between the upper portions of the rear legs of the table and is suitably attached to the said legs and to the table-top. The stationary portion of the table also comprises two front sections D and D which are arranged between the upper portions of the forward legs of the table. The sections D and D are arranged a suitable distance apart laterally of the table and attached to the last-mentioned legs and to the table-top. The table-top A is provided with an opening at extending vertically therethrough. The opening a is quadrangular.

G represents a pivotally supported loadcarrying platform which is arranged to swing in a vertical plane and occupies the opening a of the table-top, as shown in Figs. 1, 3 and 4, or depends below the table-top, as shown in Figs. 6 and 7 according as the said platform is at the one or the other extremity of its range of movement. The opening a is large enough in dimensions to accommodate a reception thereby of the platform G and a leaf R with which the platform is provided, which leaf is pivotally supported from the platform. Preferably the platform G is pivoted at its side edges, as at g, in suitable proximity to the forward wall of the opening a to the side walls of the said opening horizontally and laterally of the cabinet to render the platform capable of swinging downwardly from within the said opening or upwardly into the opening. The leaf R is pivotally secured at the ends by means of pivotal screws or members 1" to the platform G at the free end of the platform and arranged to swing upwardly independently of the platform during the lowering of the platform. into its depending position. The axes of the leaf R and platform G are parallel. The platform G is designed to bear the sewingmachine head E shown in Figs. 1, 3 and 6. The head E usually occupies more space than will permit it to swing through an opening which is not larger than the platform, and the platform if it were made large enough to occupy an opening of the size necessary to accommodate the passage of the sewing-machine head therethrough would in swinging from its horizontal and openingclosing position into its downwardly swung or depending position strike a member or members of the operating mechanism of the sewing-machine. Consequently the. opening a is made large enough to freely accommodate a swinging of the sewing-machine head therethrough, and the platform is adapted to only partially close the opening, and the leaf R is employed to substantially complete the closure of the opening in the opening-occupying posit-ion of the platform.

Means for actuating the platform G are provided and comprise a cover-forming leaf H which is hinged, as at h, to the table-top A at the left-hand end of the table. The leaf H is arranged with its axis at a right angle to the axis of the platform G and is employed in lifting the latter from its downwardly swung or depending position into its horizontal or opening-closing position. The cover-forming leaf H is operatively connected with the platform G as will hereinafter appear. The leaf H co vers the opening a in the table-top A, as shown in dotted lines Figs. 5 and 6, or projects laterally of the left-hand end and thereby forms a leftward extension of the said top, as shown in Figs. 1 and 3, according as the platform G is in its depending position or in its upwardly swung and opening-closing position.

The table-top A is provided at the top and at each side of the opening a with a horizontally arranged plate 12 which extends forwardly and rearwardly of and overhangs the rear portion of the opening a and form stops for preventing upward tiltting of the leaf R in its horizontal and opening-closing position. The leaf R is provided with an arm 13 which projects toward the axis of and under the platform in the opening-closing position of the platform. Ohviouslyduring the movement of the platform from its depending into its opening-closing position the leaf R comes into engagement with the lower sides of the plates or members 12 of the tabletop A, and is swung into line horizontally with the platform. It will be observed that the arm 13 of the leaf R engages the under side of the platform in the opening-closing position of the leaf and prevents the leaf from tilting downwardly independently of the platform in the opening-closing position of the platform and attached leaf.

The bandwheel e of the sewing-machine head is arranged in the usual manner over the right-hand end of the platform G and power is transmitted to the said wheel from the driving-wheel I of the sewing-machine through the medium of the usual belt J establishing operative connection between the said wheels. The driving-wheel I in its operative position is arranged therefore below the right-hand end of the opening a in the table-top but at the outer side of a movable leg or stand K supporting it. The stand K in the operative position of the drivingwheel is in a standing position and rests upon the floor (see Figs. 1 and 1). The stand K is shiftable from a standing posi tion into a position off the floor and in suitable proximity to the platform Gr.

Preferably the stand K is provided at its upper end and a suitable distance from the tabletop with two trunnions 15 and 15 which are spaced forwardly and rearwardly of the table and arranged horizontally and in line endwise. The rear trunnion is journaled in a bracket 16 which is suitably attached to the back 0 of the stationary portion of the table. The forward trunnion is journaled in a bracket 17 which is attached to the right-hand front-section D of the stationary portion of the table. It will be observed therefore that the stand K is capable of being swung laterally in vertical plane. The stand K when the sewingmachine is in use is in a standing position shown in Figs. 1, 2 and 4:, and in this position the driving-wheel, as already indicated, is in an operative position ready for use in transmitting power therefrom to the band-wheel of the sewing-machine head, and the said stand is swung inwardly and upwardly toward the platform while the platform G is being lowered, as will hereinafter appear, and in its upwardly swung or elevated position is arranged as near as possible to the opening a in the table-top without interfering with the platform in the depending or lower position of the platform.

Means for actuating the stand K are provided and preferably comprise the leaf H and an operative connection between the said leaf and the said stand. This operative connection preferably comprises a lever-arm I; which is formed on the upper end and projects upwardly from the stand K rearwardly of the opening a in the table-top and at the inner side of and in suitable proximity to the back C. The lever-arm 7c in the standing position of the stand K projects across the forward or inner side of the guide-bar Q. with which the back C is provided and in the direction of the hinged end of the leaf H. The guide-bar Q is arranged at the forward or inner side of and rigidly attached to the back C. The guide-bar Q is arranged therefore rearwardly of the opening a in the table-top and rearwardly of the lever-arm.k and extends from under the table-top at the left-hand end of the said opening in the direction of the right-hand end of the table. A rod m is pivoted at one end and horizontally and parallelly with the axis of the stand K to the lever-arm is at the outer end of the said arm. The rod m is arranged at the forward or inner side and longitudinally of the guide-bar Q. A pin 71 arranged horizontally and parallelly with the axis of the stand K pivots the rod m at its other end to a bar 0 in suitable proximity to one end of the said bar, which bar is arranged forward of the guide-bar Q and is pivoted at its other end, as at 20, horizontally and parallelly with the axis of the stand K and leaf H, to the said leaf a suitable distance from the axis of the leaf. The leaf H is slotted or recessed, as at 21, to accommodate the location and operation of the bar 0. The tabletop A is slotted, as at 22, to accommodate the location and operation of the bar 0. The pin 97. projects rearwardly of the bar 0 and connected rod m and bears a roller 23 which rests and is arranged to travel on and longitudinally of the guide-bar Q. which (see Fig. 1) has a horizontally arranged upper end portion 24: arranged to form a seat for the said roller when the leaf H is in its top-extension-forming position. The central portion of the guide-bar Q extends from the horizontally arranged upper end-portion 2a of the bar downwardly and in the direction of the right-hand side of the table, and the other and lower end-portion 25 of the said bar curves upwardly in the direction of the right-hand end of the table-top. The arrangement of the parts is therefore such that the roller 23 has bearing on the guide-bar Q during the actuation of the stand K. It will be observed that the lever-arm is, rod m and bar 0 constitute lever-mechanism establishing operative connection between the said stand and the leaf H, and that the roller 23 and guide-bar Q, constitute means for properly guiding the said lever-mechanism and thereby facilitating the operation of the said lever-mechanism.

Preferably the inner end of the bar Q has the shape and dimensions required to overlap and abut against the under side of the table'top, as at 26, (see Fig. 1) in the topextension-forming position of the leaf H, and the table-top is preferably provided with an antifriction roller 27 arranged to avoid friction between the said bar and the tabletop during the operation of the levermechanism comprising the said bar.

The relative arrangement of the parts is such that the stand K is in its standing position or in its upwardly swung or raised position according as the leaf H is in its topextension forming position or in its openingcovering position, that the said stand is actuated from its standing position into its raised position during the movement of the said leaf from its top-extension-forming position into its opening-covering position, and that during the movement of the said leaf from its opening-covering position into its top-extension-forming position the said stand moves from its raised position into its standing position. The stand K also carries the treadle of the sewing-machine, which treadle comprises a horizontally arranged bar T which is arranged at and extends transversely of the inner side of the said stand in suitable proximity to the free extremity of the stand.

To accommodate the location and operation of the treadle the bar T is provided with two pivot-forming members 2? arranged at opposite ends respectively of the bar and in line endwise, and the treadle also comprises a foot-operated plate U which is provided at its right-hand end with ears n which are journaled upon the pivotal members t of the bar T. The bar T is provided at its under side and centrally between its ends with an ear 30 which is journaled upon an axle 32 which projects laterally and inwardly from the stand K and is provided at its inner end with a member 33 having two feet 34 located at opposite sides respectively of the axle and arranged to rest upon the floor in the standing position of the aforesaid stand. The foot-plate U of the treadle is provided a suitable distance from the bar T of the treadle with a depending member 35 which embraces the upper portion and is thereby journaled on the axle. It will be observed therefore that the bar T and plate U constitute the treadle which is journaled on the axle 32, and the said bar is provided at its rear end with a rearwardly and laterally outwardly projecting arm 36 which is operatively connected by a pitman 37 with the driving-wheel I. By the construction hereinbefore described it will be observed that the treadle-plate U is adapted to be swung upwardly and toward the inner side of the stand K and that the said plate is thus swung into an inoperative position,

preparatory to the actuation of the said stand from its standing position into its raised position, and it will be observed therefore that in the upper position of the stand K and connected treadle and in the lower or depending position of the platform G the treadle-plate U is interposed between the said platformand the said treadle, as shown in Figs. 6 and 7. It will be observed therefore that in my improved sewing-machine table the treadle is shifted by and during the actuation of the leaf H through the medium of the stand K and lever-mechanism which constitutes the operative connection between the said stand and the said leaf, and that the treadle is in its upper position under and in close proximity to the range of movement of the platform G, as shown in Figs. 6 and 7, or in its lower position, as shown in Figs. 1 and 2, according as the said leaf is in its opening-covering or in its top-extension-forming position.

The stationary portion of the table is provided between the left-hand legs with a laterally movable bracket m which is in position under the left-hand end-portion of the table-top in the opening-covering position of the leaf H, as shown in Figs. 5, 6, 7 and 9, and is actuated laterally and outwardly during the actuation of the said leaf from its openingcovering position into its top -extension formin position. Preferably the said bracket 09 see Figs. 3 and 7) is hinged at its forward end, as at 40, to the stationary portion of the table and placed with its axis arranged vertically, and the said stationary portion of the table comprises a cross-bar 42 arranged horizontally and extending between and secured to the left-hand legs of the table, which bar is arranged at the inner side of the aforesaid swinging bracket in the inner and inoperative position of the bracket.

The swinging bracket 00 (see Fig. 9)- is held in its inner and inoperative position by a latch which is supported from the bar 42 and has arms 43 and 44 projecting laterally in opposite directions respectively and pivoted horizontally and longitudinally of the said bar, as at 45, (see also Fig. 10) to a bracket 46 which is rigid with the said bar. The latch-arm 43 is provided at its free end with a downwardly projecting member 47 which overhangs a laterally and inwardly projecting arm 48 of the bracket 00. That is, the bracket w is provided at its inner side with a laterally and inwardly projecting arm 48 which has an outwardly facing shoulder or surface 49 overlapped by the member 47 of the latch-arm 43 in the inner and inoperative position of the bracket 00 when the leaf H is in its openingcovering position.

The arm 44 of the latch is provided at its inner end (see Figs. 9 and 10) with a shoulder or projecting member 50 abutting against the under side of the latch-arm 43 in the operative position of the last-mentioned arm. A suitably applied torsional spring 5 which is coiled around the pivot 45 and attached at one end to the latch-arm 43 and at its other end to the latch-arm 44 acts to retain the 1atcharm 43 in its operative position and also acts to retain the latch-arm 44 in position holding its projecting member 50 in contact with the under side of the latcharm 43. The latch-arm 44 is arranged in the path of the member 33 of the axle 32 during the actuation of the drivingwheel-bearing stand K, but by the construction hereinbefore described it will be observed that the latch-arm 44 is tiltable upwardly independently of the latch-arm 43 and therefore the latch-arm 43 is not operated during the actuation of the stand K from its standing position into its raised position, but during the movement of the said stand from its raised into its standing position the axle-member 33 comes int-o engagement with the top of the latch-arm 44, as shown in Fig. 9, and thereby actuates the said latch-arm 44 and consequently the other latch-arm 43 in the direction required to render the last-mentioned latch-arm inoperative and permit the bracket 00 to be actuated laterally and outwardly (see Figs. 3, 4 and 7) by a. suitably applied spring 7 which is supported from the stationary portion of the table and engages the inner side of the said bracket, which spring constitutes means acting to retain the said bracket in its operative position under and supporting the leaf H when the said leaf has been actuated into its top-extension-forming position.

The platform G is preferably operatively connected with the leaf H through the medium of the driving-wheel-bearing stand K which is provided at a suitable point between its axis and the treadle with an arm 52 projecting laterally and inwardly from the said stand. A cable or flexible connection 53 is attached at one end to the outer end of the arm 52, thence leads upwardly to and over the rear and top of a guide-sheave 54 with which the table-top is provided rearwardly of the opening a, thence leads to and is attached to the free end of a rearwardly projecting arm 55 with which the platform G is provided at its under side centrally between the side edges of the platform. 'Ob

viously therefore the platform G is actuated from its lower position into its openingoccupying position during the movement of the stand K from its raised into its standing position, and the platform lowers by gravity during the actuation of the said stand from its standing into its raised position.

Preferably the stand K is provided with a guard 56 extending ciroumferentially of the lower portion of the driving-wheel I and arranged to prevent displacement of the belt J from the said wheel when the said stand is in its raised position and the platform is in its lower position, as shown in Fig. 6.

Between the front-sections D of the stationary portion of the table is arranged a leaf 57 for closing the opening between the said sections in the lower position of the platform G and actuated inwardly and out of the way during the movement of the platform into its upper position. The leaf 57 is hinged at its upper end, as at 58, to the table-top and arranged to swing in a vertical plane. A coil-spring 60 connects the leaf 57 at the inner side of the leaf with the arm 55 of the platform. The leaf 57 is provided at its inner side with an inwardly projecting member 59 engaged by the arm 55 of the platform. The spring 60 holds the leaf 57 yieldingly connected with the platform. Obviously the leaf 57 is swung inwardly during the actuation of the platform into its upper position and swung outwardly during the lowering of the platform.

We would here remark that the arm. 55 of the platform G depends downwardly between adjacent arms of the driving wheel I in the raised position of the stand K, and the treadle-plate U is provided with a slot 39 arranged to accommodate the location of the said arm during the actuation of the said stand into the said position. Also the stand K has such an openwork design that the movement of the said stand into its raised position is not interfered with by the said arm 55.

By the construction hereinbefore describedit will be observed that the stand K when in its upright position and resting on the floor is substantially as firm as it would be if it were rigid with the stationary portion of the table, and that the treadle does not have to be removed from the said standpreparatory to raising the stand off the floor, nor does the pitman 37 have to be detached from the treadle and driving-wheel to permit movement of the said stand from its upright position into its raised position. It will be observed also that the said stand K and the cable 53 which connects the stand with the platform Gr constitutes means for holding said platform in its upper position while the stand is in position. resting on the floor. That is, the stand K, because it rests on the floor in its upright or lower position,

is firm enough in the said position to hold the platform G in its upper position without necessitating the use of locking devices or special mechanism for holding the said platform in its upper position. However, the cable 53 may be disconnected from the stand K and the platform G supported in any well known manner without interfering with the utility of the stand K in shifting the treadle, driving-wheel and operative connection between the driving-wheel and the treadle out of the way when the sewingmachine is not in use, and the leaf H and mechanism establishing operative connection between the said leaf and the stand K constitutes means independent of the platform. G for positively actuating the stand K from the one to the other of its extreme positions.
