My invention relates to improvements in r sewing machines and 18 more especially d1- rected" to that type of machine adapted for a childs use.

'5 The object ofmy invention is to provide a simple machine, onethat is easily operated and having very few parts to be adjusted. A further objectof my invention is to provide a feeding mechanism to move the mate- "lorial underthe usual presser foot.

Another object of my invention is to, provide a machine having the usual thread looper' and its operating shaft, the latter being provided, with means for regulating the v movement 'of'the material under the presser foot) o In the accompanyingdrawings,

' Figure 1 is a side elevation, of myimproved machine'showing the same as being clamped M Figure 2 is an enlarged detail view of the j. bed'plate of the machine, the same showing the under side ,thereofand to which is con nected the improved feeding mechanism, and

' f", Figure 3fisa'detail view' taken on the line" 33 of Figure 2. I

Referring tothe accompanying drawings v in detail, wherein like reference characters denote corresponding parts throughout the iao theyseveral views, the numeral 1 indicates the base of my improved machine, the same z being formed of; suitable material, prefer- {ably wood, and having hingedly connected thereto a bed plate ,2 formed of; sheet metal and provided withk downturned marginal ,fianges' 3. The base 1 is provided in its front wall with an opening 4 in which isre- I ceivable the free end ofa clamp 5, the same being'adapted to securely clamp the base 1 upon a suitable support 6.

Asdisclosed in the drawings, the upper face of the bed plate 2 is substantially flat v throughout its entire length and hassecured thereto at one end theusual goose-neck arm 7,.the same having mounted therein a driving I shaft8' which is adapted to be rotated by a handvwheel 9, or any suitable driving means.

- The other end of the drive shaft 8 has con c iprocatingv the needle bar 10.

I pulley 13 is positioned. The looper shaft 14 'noted that the arms 39 and are struck 9d 4 nected thereto the usual mechanism for, re

1926. Serial No. 113,882.

Secured to the drive shaft 8 is a belt pulley 11 around which passes a belt 12, preferably of a flexible nature, the same further engaging a belt pulley -18 secured toone end of a looper shaft 14: carried upon the under face of the bed plate 2.

As disclosed in Figure 2, it will be noted that the bed plate 2 has provided therein at one end an opening 15 under which the belt is mounted within an arm 16 formed integral with the bed plate 2 and bent downwardly at right angles therefrom, the lower end of which s bifurcated and has positioned therein a bearing 17 through which the shaft 14 passes. I The other end of the bed plate 2 is provided with a pair of spaced transversely extending slots 19 and 20in which the material feeder 21, hereinafter morefully described, is adapted to move. That portion of the bedplate 2 which lies between the slots 19 and'20 is provided with an opening 35 for the passage of the needle therethrough during its operating strokes.

As disclosed in Figure 2, it will be noted that the under face of the-bed plate 2 has detachably secured thereto a circular plate 22, the central portion of which is provided with a cutout portion 23. The plate 22 has formed integral therewith a downwardly extending arm 2%, the intermediate portion of Which'is provided with a horizontally arrangedslot 25 which receives therein one end of a feeding mechanism 21, the other end of 35 which is'retained against lateral movement by a pair of downwardly extending fingers 26 which are likewise formedintegral with the ring'22.

The feeding mechanism 21 is composed of a body portion 21 having ends 37 and 38 which are connected by spaced arms 39 and 40 which are receivable within the slots 19 and 20." As disclosed in Figure 3, it will be the slots 19 and 20, I have provided an arm 99 27 whichis formed integral with the body portion 21 of the feeder, the free end of which has provided therein an enlarged opening 28 which is adapted'to receive an eccentrio block 29, detachably secured tothe looper shaft 14 by the locking screw 30. To support the adjacent end of the shaft 14, the plate 22 has formed integral therewith'a downwardly extending arm 31 in which is positioned a bearing 32 for the reception of the shaft 14.

As'disclosed in Figure 3, the end of the looper shaft 14' is provided with a trans verse slot for the reception therein of the usual looper, not shown in the drawings, but clearly understood by those skilled in the art.

The bed plate 2, as previously mentioned, is hingedly connectedto the base 1 and to lock the same thereupon I have provided upon the under face of the bed plate 2 a pair. of downwardly extending resilient fingers 83, the lower ends of whichare pro-- vided with enlarged portions adapted to be received within a groove extending along theinner face of the base 1.' As further disclosed in Figure 2, it will be noted that one of the resilient fingers33 is positioned under vided in the bed plate, a depending. arm 2 formed integral with said feeder and eccenhaving one end supported for reciprocatory movement and the'otherfor vertical movetrically connected to said shaft, saidfeederment in elements formed integralwith said a the plate 22 and retained to the plate 2 by I the securing means for the plate 22.

fHaving thus briefly describedmy invention, I will now endeavor to explain its operation. r I a Upon the rotation of the hand wheel 9, rotary movement'will be imparted to the looper shaft 14 and upon therotation of the latter the feeding. mechanism will be moved back and forthfwithin'the slots 19 and 20 for the purpose of moving the material across the bed plate 2. This movement is accomplished through the shaft 1 1, theeccentric 29 and the arm 27, which is formed integral with the feeder 21.

From the foregoing, it is thought that the construction,operation and many advantages of the here-1n descrlbedinvention will be ap parent to-those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction. may be resorted to without departing fromthe combination of a bed plate having mounted thereon a needle operating means including a rotatable shaft, ,a plate detachablyfconnected to the under face of said bed plate and forming a support for a material'feeder,

said feeder including an elongated strip of metal having its intermediate portion slotted to provlde spaced arms, said arms being bent upwardly for: movement within slots pro-
