1 Claim. (Cl. 311.12)

:I-his invention `relatesrto support devices forsewing machines. More particularly, the invention has reference toasupport board in the natureof an insert, removably and ixedly connectable to the top of a ;sewing machine table or cabinet, to supporta selected ,makeVY or model vofsewing machine.

Heretofore, every make or model of sewing machines, differing in Sonie wespect from other machines, Vhas re- .quiredla cabinet ortablejtop specially eut to support Vthe same. Said table top or cabinet has, as a result, been incapable. of supporting any other machine except that florffwhich it has been particularly designed.

This is, as be appreciated, a somewhat undesirable situation. lt is clearly a matter of some expense to form differently shaped table tops according to the particular makes and sizesof sewing machine models. Accordingly, it isV the main` object of the present invention ,to provide an insert or support board fora sewingmachine which vvv,illr.be designed to receive a particular machine, and will vf urthrerrbe designed so as to beiremovably and iixedly Urn'ountable upon `a Vtable or cabinetgtop, nwithsaid table or cabinet top so designedas to receive anytiof a-substantial number or Yinserts differing from oneanother in respect tothe type of machine to be supported thereby.

A Vfurther ,object of importance is to so shape the insert Vvas ,to cause the ,outer conguration ofthe same torsubstantiallyrrnatchian insertfboard-receiving opening formed-,in `the table Or ,Cabinetten with-thatrrfi9nfthe insert Ihat'sshaped torreceiveihebese. of. the sewinsmahine w' be supperedbeins formdto thel speialhape and dimensions that' render the insertcapabgle fof supporting the particular machine.

Still anotherbect is to Providence@ Q11. the ,cabinet 0f ,fable tcp extending adjacent the insert-@wiring Opening -thereof soshaped as to support thepinsert in the provided opening, while at `the sametirnepermittingthe fixed connection of the insert to said meansghereby to prevent relative movement or vibration betweenbthe table top and insert.

Still another object is to so Adesign the above mentioned means as not to interfere in any way with l the passage of a drive belt from the sewing-machine through the table top and insert to a drive motorrmountable upon the underside ofthe table top.

AFor further comprehension of the inventiomandvofithe vobjects and advantages thereof, reference will'beA had to the followingdescription and accompanyingidrawings, and tothe appended claim in whieh'the various novel' features offtheinvention are more particularly set forth.

jln the accompanying drawings forming a material part ofqthis disclosure:

Fig. l is aside elevational View of asewingrinnachine table having mounted therein theinsertqfornied arcprding to the present invention, theV dotted-lines show inga vsewing machine, its associated ',drivernotor, and related Vparts.

V"lf'ig. 2 is a fragmentary top1 plan view ofqthetable-,gnd

insert, on an enlarged s'aleportions ofthe'insert being against the ,undersideflh bar atented Mar. 12, 1957 broken away, the sewing machine-beingshown in dotted The reference numerati@ has been applied` generally in the several iigures of the drawing to aseWingmachine table including cornerlegs 12 secured to 4and-supporting a horizontal, lapt, tabletopA 14. Althougha table is zilus- .trated, o'm/iouslythe` structure-can beof closed, cabinetlike construction if desired.

n anytevent, Ja drive motor 16 is mounted against lthe underside of the table top (Fig. l) in the u suaL manner, land by means of a beltvl passing Vfrom the moton to a .locationabove thertable top, drivesv a sewing machine havinga housing tland head 22,

Ordinarily, .the sewing` machine is mounted directlylin anopening providedV in the table top, Vwhich openingis shaped Vto Vreceive Va particular machine, and -is not adapted Vto receive anyY other machine differing from the intended machine inrespect fto location of its drivebelt, Athe size Vof its base, and the outer configuration of-said hase. Hou/ever, in accordance with the present invention, in the illustrated sewing4 machine table there is formeda large, rectangular Vopeningfl, 4opening -upon the front edge AVof thetable top as shown to particular advantage in'Figs. 2 and 6. flhe opening 24 is substantially vgreater than the usual opening formed ina sewing machine table top to receive the machine housing and head.

The insert plate structure member constituting the present ,invention has been illustrated per se-inFig. 45, and in the form or'l Figs. L5, vcon'iprises a rectangular, lflat board or plate structure member 26, thetbickness of whichpis equal tothe thickness of the table,top. 14, and the outerconguration of which corresponds rtoghe shape of opening 24. y As will be ,notedy in P ig. 2, in length and width theV support plateor boardlmois slightly smaller than the corresponding Ydimensions of thefopeningj24, by perhapsy Ms of an inch. YThis facilitates Athe seating of the support board 2,5 in the opening V24, without diiculty and without projection of the vfron'tvled'ge of the support boardV forwardly beyond the ,front edgeof the table top.

Formed in the support plate or board 2e is a series Aof openings located at the corners thereof, said openings including a pair of back or inside corner openings 2S, and a pair of outside corner or front openings 34B.

Extending longitudinally of opening 2e, at t eA open front thereof, is a rigid, relatively narrow, straightl front support bar 32. Bar V32 is` greater in length than opening 2l,'the ends of thebar underlying the table top vlhbeyond the ends of opening 2%, asbest `shown in Figs. l and 2. The support-bar 32,*aty locations spaced inwardly from the'ends thereof, hasl apertures Sai-that register with the openings 3G (seeFig. l)-whe n the-plate-Q is lfitted into .opening-24.' vThe bar 32,191 locations beyond the'ends of opening-24,1has Vother openings oraperturesl 36.

Bolts 38 extend through the registering .openings), 3,4, toconnect the front edgefportion or" the platezlto the bar,zZ, whenvtheplate 2,6 visV disposed in opening 2.4.vsith its front edge pertienssurnertedncn.thebara wing nuts sir-.equivale h .Connecting bolts 1.40 areext Ain s 36 en dt elevation with Yafrxslspssi connect the bar 32 to the table top in the position previously described herein.

At the back corners of the openings 24, there are provided back support bars'or brackets 42. These are also formed from strong, relatively narrow, metal bar or strap material, but as shown in Fig. 2, these are substantially Shorter in length than the front support bar 32, with Veach of the rear corner support bars extending diagonal- Y midlength portion of each corner support bar 42, which i is exposed in the corner of the Vopening 24, has an aperture receiving a bolt 46. The bolts 46 extend through the rear corner openings 2S of the plate 25, said openings 28 being in registration with the midlength open-Y ings of the rear corner support bars 42.

The corner bars 42 support the rear corners of the plate 26, as will be apparent, and through the medium of the bolts 46, which are fitted with wing nuts, the plate 26 is securely lixed at its rear corners to the table top.

It will be seen that in this way, the plate 26, though readily removable for use of any of a selected number of said plates diifering from one another with respect to the type of machine which they can support, is swiftly and easily attachable to or detachable from the table top, and when attached to the table top, will be held securely against vibrations relative to said top.

Means is provided in the plate 26 to facilitate extension of the drive belt to the supported sewing machine, and care is taken that said means does not interfere with movement or proper positioning of the drive belt 18. As shown in Fig. 2 and also in Fig. 4, a short support bracket 48 is spaced longitudinally of the rear edge of the opening 24 from one of the corner support bars 42. Bracket ing receiving a connecting bolt 50 which extends through the table top. The other or free end of the bracket 48 projects inwardly of the opening, to underlie the board i or plate 26 and aid in providing a support therefor.

The bracket 48 and the adjacent corner support bar,

42 are disposed in close proximity to and at opposite sides of a transverse slot 52 formed in the plate 26. Slot 52 extends adjacent one end of the plate 26, from the midwidth area of said plate 26 to the back edge thereof,

' 48, at one end, underlies the tabletop, and has an openand is in registration, at sai-d back edge, with a transverse slot 54 formed in the table top 14. The slots 52, 54 cooperate when the plate 26 is properly supported to define an elongated opening through which the drive belt 18 extends. Proper support at this particular location is provided by the bracket 48 and the corner support bar 42 adjacent thereto.

Assuming that it is desired to mount a particular sewthe usual fiat base 60, and said base is of la shape and dimensions corresponding to those of the opening 56. Base 60 is thus seated snugly in opening 56, with the corner portions of the base effectively supported upon the cushioned ledges 5S.

When the sewing machine is so supported, the drive' belt 18 can be extended through the registering slots 52, 54, and the structure is ready for use.

In Figs. 6 and 7, there is illustrated a different insert plate structure member 26a constructed to supporta different type of.sewing machine designated atr20a. Y'This illustration is for therpurpose of showing how different `inserts, supporting various types or sizes of machines,

4 can all be interchangeable in respectV to a single sewing machine table top such as that shown at 14 having the rectangular opening 24.

ln the modified form, the insert plate 26a has an outer configuration matching that of the insert 26. As a result, the insert plate 26arcan be supported upon the front support bar 32 and the rear corner support bars 42 as well as on bracket 48. In the modied form, however, the opening 56a is substantially different in respect to its 'dimensions `and shape from opening 56, since a different type of sewing machine 20a, having a baise 60 corresponding to opening 56ais to be supported. Opening 56a, in'this instance, is not provided with cornerY support ledges 53, but rather, has longitudinally extending front and rear ledges 58a (Fig. 7), merging into end ledges 59a, adapted to support the ends of the sewing machine. j

The ledges 58a, 59a are quite narrow as comparedto the area of the corner support ledges 58, and this is for the purpose of providing clearance for a sernicylindrical, depending portion 2 of the sewing machine housing 20a. The portion 62 has ears 64, capable of being bolted to the inner, vertical surfaces of the front and rear ledges 58a,

The belt-receiving slot of the insert plate 26a has been designated at 52a, and as in the first form of the invention, is aligned with the slot 54 of the table top 14.

Further, in the modified form, the corner openings 36a `are used, and as in the first form, register with the openings 34 of the bar 32, to receive theV connecting bolts 38. v

The rear corner openings of the modified adapter 26 will be disposed similarly to the rear corner openings 28 of t'he rst form of the invention, to permit extension of the bolts 46 therethrough.

it'will be seen from the above that a single table top 14 can be manufactured, adapted to receive all the different sewing machines of the particular manufacturer. Further, it will be noted that the table top 14 can even be adapted to receive the sewing machines of any manufacturer, simply by manufacture of the table top 14 with a plurality of inserts being also manufactured each of which is adapted to support a different make, model, or size of sewing machines. The structure is particularly useful in businesses in which, for example, there is a large operation in respect to the conversion or renewing of sewing machines, and the sale of traded-in equipment. In such an establishment, merely by manufacture of a single type of table and a plurality of inserts for receiving different machines, any machine can be mounted attractively upon a table, and when so mounted, will appear to have been designed particularly for installation on said table or cabinet.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, Yand desire to secure by United States Letters Patent is:

ln the combination of a power-table having atable top provided with a rectangular cutout therein opening outwardly of one side of theV table top and with openings adjacent the front and rear corners of the cutout portion, a sewing machine adapted to be received within said cutout, a power transmitting motor supported by said power-table and means operatively to connect said motor with said sewing machine; the improvement consisting in the provision of a unitary means for mounting said sewing machine within said table cutout, said unitary means comprising an insert adapted to'be remov- V ably mounted within said table cutout, means -for locking said insert to said table top, said insert having a rectangular shaped cutout formed therein of a size and shape to accommodate said sewing machine and having openings at the corners thereof, ledges formed in the insert at the corners of the cutout for removably supporting the sewing machine thereon and cushioning pads on said ledges, said locking means including an elongated at bar extending along the front long edge of the insert on its bottom surface and underlapping the adjacent edges of the table top, said bar having openings in line with the front corner openings of the insert, and in line with the front corner openings of the table top, bolts extending through said aligned openings, nuts on said bolts, at bar brackets extending diagonally across the rear corners of the insert on the bottom surface thereof, said brackets having openings in line with the corner openings in the insert and the rear corner openings in the table top, bolts extending through said latter aligned corner openings, and nuts on the ends of said bolts.
