(Cl. 112-2l8) 7 Claims. l

This invention relates to a sewing machine and more particularly to a sewing machine of the portable type.

The invention has as a primary object to provide a carrying handle for a portable sewing machine which may be folded flush with a surface of the machine.

Another object of the invention is to provide a portable sewing machine with a pivoted lifting handle which may be easily gripped when in its folded position for raising it to the carrying position.

A further object of the invention is to provide a pivotal connection between a carrying handle and a portable sewing machine which connection is sturdy and easy to assemble.

A still further object of the invention is to provide a detent mechanism for a pivoted lifting handle which will hold the handle in any one of a plurality of positions.

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 drawings of a preferred embodiment of the invention, from which the several features oi' the invention and the advantages attained thereby will be readily understood by those skilled in the art.

In the drawings,

Fig. l is a rear elevational View of a portable sewing machine embodying the invention.

Fig. 2 is a top plan view of the sewing machine shown in Fig. 1.

Fig. 3 is a partial view taken on line 3--3 of Fig. l.

Fig. e is a partial sectional View of the handle hinge structure taken on line 4--4 of Fig. 2.

Fig. 5 is a partial sectional View of the handle hinge structure taken on line 5-5 of Fig. 4.

Referring specifically to the drawings, a portable sewing machine is shown having the usual bed II carrying a curved bracket-arm I2 which terminates in a head i3. The bracket-arm indicated generally at I2 comprises a body portion |4 fastened to the bed and a removable portion or cover-plate l5. A bed extension I6 is pivotally attached to the bed I. The bracket-arm coverplate l5 is attached to the body portion I4 by screws Il'. The top of the cover-plate I5 is formed with parallel slots I8 and I9 extending from slots 2|! and 2l, respectively, in one edge of the coverplate, substantially across its width. A U-shaped lifting handle 22 is provided with arms 23 and 24 positioned in the slots I8, and I9, 2|, respectively, which arms are contoured to be flush with the upper surface of the cover-plate I5 when the handle is in retracted position, shown in solid lines in Fig. 4. The grip portion of the handle 22 is formed with a U-shaped cross-section as shown in Fig. 4. A depression 25 is formed in the top and edge of the cover-plate I5 between the slots 2o and 2| to receive the grip portion of the handle I5. Bearing bosses 26 and 2l depend from the iower surface of the cover-plate and are located one on each side of the slot I8 at its inner or blind end. One end of the arm 23 extends between the bosses 2t and 21 and is engaged by a pivot pin 28 passing through a hole 29 in the arm i8. The bosses 25 and 21 are provided with bearing slots 3B and 3|, respectively, open at their lower ends to receive the pivot pin 28 after it is assembled in the handle arm. The end of the handle arm is formed as a cam having two flat faces 32 and 33 which are selectively engaged by a cantilever spring 34 fastened to the cover-plate i5 by a screw 35. As may be clearly seen in Fig. 4, the spring 34 presses against the end of the handle arm to hold the pivot pin 28 firmly seated in the bearing slots 3i) and 3l. Since the handle arm 2li is pivoted to the cover-plate in the same manner that the arm 23 is pivoted to said cover plate, a detailed description of the pivotal connection for the arm 24 is not believed to be necessary.

The handle is easily assembled to the coverplate by positioning the arms of the handle in the slots I8 and i9 and inserting the pivot pins 28 through the journal holes 29 in the arms. The pivot pins 2B are seated in the slots 3o and 3| and the cantilever springs 3d are then fastened to the cover-plate to hold the handle and pivot pins in position. This cover-plate and handle assembly is securely attached to the body portion I4 by the screws I'I.

When the sewing machine is not in use and is to be stored, the lifting handle 22 is pressed to the folded position shown in full lines in Figs. 1 and 4 of the drawings. In this position, the handle arms 23 and 2t are positioned in the slots |8, 2@ and IS, 2|, respectively, and the grip portion of the handle is positioned in the depression 25. Each cantilever spring 34 engages the flat face 32 of the cam on the end of a handle arm and retains the handle in the folded position, flush with the outer surface of the bracket-arm. Thus there is no protruding lifting handle which requires extra storage space. When it is desired to carry the machine, ones ngers may be easily engaged in the U-shaped grip portion of the -J handle 22 to raise the handle to the position shown in broken lines in Figs. 1 and 4. In this position, each cantilever spring engages the flat face 33 of a cani and retains the handle in the upright position.

From the foregoing description, it is apparent that I have provided a simple lifting handle for a sewing machine which may be folded ush with the outer surface of the machine for convenient storage in a limited space. Further, the novel hinge construction for the handle provides a pivotal connection which is easily assembled and which also functions as a detent means for retaining the handle in selected positions.

Having thus described our invention, what we claim herein is:

1. A sewing machine having a bed, a bracketarm carried by said bed and having a hollow horizontal portion terminating in a head, said bracket-arm having slots therein, a lifting handle g.

positioned in said slots flush with the outer surface of said bracket-arm, said lifting handle having a pivot portion disposed in said slots, and a pivotal connection between said pivot portion of said handle and said bracket-arm.

2. A sewing machine having a bed, a bracketarm carried by said bed, said bracket-arm comprising a hollow horizontal body portion and a removable cover-plate having a plurality of slots,
