Attorney-Young and V US. Cl 66/115 7 Int. Cl D04b 15/00 ABSTRACT: The needle bed of a domestic knitting machine Field 011' Search 66/114, has an upper plate that projects at the back and front to form 1 15, 60 flanges which constitute guides for the camslide,

L l O I 1 I6 26 26 I6 1 NEEDLE-BEDS FOR DOMESTIC KNITTING MACHINES This invention relates to domestic knitting machines having needle beds of box form for a series of needles or sinkers.

The beds of these machines are usually made of sheet metal with guiding means for needles or sinkers, consisting of a series of slots formed in the upper plate of the bed, which slidably receives the butts of the needles or sinkers.

The camslide which, as it is oscillated along the bed, projects and retracts the needles or sinkers, is usually engaged in guides on the upper plate, which are added to the plate and secured in position.

The object of the present invention is to provide a needle bed with which the camslide may be directly engaged and which is, therefore, simpler in construction than the usual arrangement.

According to the invention, the upper plate of the bed overhangs the bed at both back and front of the bed, and each overhang constitutes a guide for the camslide.

FIGS. l-5 show various cross-sectional views of the embodimens of the invention.

Various fonns of the invention are illustrated in the accompanying drawings. In FIG. I, the bed is a box composed of a trough-shaped base 10, which may be unitary or made up of different parts connected together, and an upper plate 12 secured inwardly turned flanges 14 on the sides 16 of the trough. The plate 12 projects beyond the trough to provide flanges 18 which are engaged by the camslide 20 which is formed with recesses 21 engaged over the flanges 18, to permit the camslide to be oscillated freely but without significant play.

ln FIG. 2, both flanges 14 are directly forwardly. ln FIG. 3, both flanges l4 are directed rearwardly. In FIG. 4, the flanges I4 are both turned outwardly. In FIG. 5, there is a double flange 22 at the top of each side, each secured to the plate 12.

All the constructions serve the same purpose, namely, to provide guides for the camslide without structure additional to the upper plate.

Needles 24 are slidably mounted in slots 26.

I claim:

I. A needle bed for a domestic knitting machine comprising a box section lower portion having upstanding parallel sidewalls, a slotted upper plate which is wider than and formed separately from the lower portion, resting on the sidewalls with the latter spaced from the edges of the upper plate so that laterally projecting flanges are formed at each side of the upper plate, and securing means securing the upper plate to the sidewalls.

2. A needle bed as claimed in claim 1 in which the lower portion walls have laterally projecting flanges and the securing means connects the upper plate to the flanges.

3. A needle bed as claimed in claim 2 in which the securing means are screws.

4. A domestic knitting machine comprising a needle bed as claimed in claim 1 and a camslide with parallel longitudinal recesses which slidable receive the flanges.

Claims (4)

1. A needle bed for a domestic knitting machine comprising a box section lower portion having upstanding parallel sidewalls, a slotted upper plate which is wider than and formed separately from the lower portion, resting on the sidewalls with the latter spaced from the edges of the upper plate so that laterally projecting flanges are formed at each side of the upper plate, and securing means securing the upper plate to the sidewalls.

2. A needle bed as claimed in claim 1 in which the lower portion walls have laterally projecting flanges and the securing means connects the upper plate to the flanges.

3. A needle bed as claimed in claim 2 in which the securing means are screws.

4. A domestic knitting machine comprising a needle bed as claimed in claim 1 and a camslide with parallel longitudinal recesses which slidable receive the flanges.
