8 Claims. (01. 66-115) This invention relates to a knitting machine and more particularly to a construction of needle bed which may be used for guiding jacks as well as needles. 5 In the drawing:

Fig. 1 is a sectional view of a needle bed which may be in the form of a needle cylinder; Fig. 1a is a view similar to Fig. 1 but showing a modified construction of needle bed;

10 Fig. 2 shows side and end views of one of the needle walls which walls are adapted to be assembled in tricks or grooves provided in the needle bed or cylinder;

Fig. 3 shows views in side and end elevation 15 of a wire or other member which is adapted to be assembled in the .needle bed to provide a hardened support for a needle;

Fig. 4 is a view in section similar to Fig. 1

but showing the parts shown in Figs. 2 and 3 as- 20 sembled with the needle bed;

Fig. 5 15 a fragmentary view in front elevation of the elements disclosed in Figs. 2 and 3 in assembled position;

Fig. 6 is a detail view of an element for re- 25 taining the needle walls in position in the needle bed; and Fig. 7 is another view of the retaining means .shown in Fig. 6.

The needle bed indicated generally, by the 30 numeral I consists of two

parts

2 and 8 detachably secured together as by means of screws 4. The outer face of the portion 2 of the needle bed is provided with a series of tricks or grooves 5 defined by walls 6. Adjacent to the upper end 35 of the portion 2 there is a recess 1 undercut as at 8, within which recess readily removable walls 9 are insertable. When a wall is inserted as indicated in Fig. 4, a lateral projection l seats within the recess 1 the upper edge of which pro- 40 jection I0 is beveled as at H to fit the undercut portion 8. The walls are notched or recessed as at I 2, hardened wire or other metallic elements I! being assembled with the needle bed as indicated in Figs. 4 and 5. Such elements are 45 between adjacent walls 9, and serve when in position in the needle bed as shown in Figs. 4 and 5, to provide hardened surfaces to accommodate the sliding movements of the needles and/or jacks. The wires or other elements l3 are oil'- 5 set as at I, the offset portion of each element consisting of diverging arms so that, in assembling, such oiiset portions llof the elements I 3 may be sprung or snapped into the recesses I2, thus being frictionally retained therein.

55 Adjacent to the lower ends of the walls 8 and slots 5, plates such as l5'are inserted in a recess l6 and retained in position therein as by means of screws l'l. As will be noted from inspection of Fig. 4, the plates l5 have their opposite faces beveled so as to wedge into engage-' 5 ment with a wall of the needle bed and the lower faces or edges it of the needle walls, such engagement causing the projections ill of the needle walls to be maintained in firm engagement with the upper portion or face of the needle bed de- 10 fining the notch or groove 1.

Whereas in Fig. 1 the needle bed or cylinder is shown as consisting of two parts connected by means of a screw 4, in Fig. 1a the needle bed or cylinder l' is shown as being integral.

The needle beds l and I may be integral or may be made in sections connected together; furthermore, the needle beds may constitute a so-called fiat needle bed or a needle cylinder.

In the foregoing description needles and jacks have been referred to as being adapted to slide in the slots provided in the needle bed. Similar- 1y elements such as l3 may be utilized for supporting sinkers or other knitting instrumentalities which are slidable in sinker heads or like supports.

Whether the knitting instrumentalities are slidable in slots provided in a needle bed having integral or removable walls as shown in the drawing, or are slidable in other supports, the use of hardened elements such as I3 permits the use of a needle bed or other knitting instrumentality support made of, relatively soft material.

I claim:

1. An element adapted to be inserted in a knitting machine and act as a support for knitting instrumentalities, consisting of a wire-like member having a bent portion intermediate its ends by which it is adapted to be removably held in position in a knitting instrumentality bed.

2. An element adapted to be inserted in a knitting machine and act as a support for knitting instrumentalities, consisting of a strip-like ele-- ment such element being provided with an offset intermediate its ends for frictional and detachable engagement with a needle bed the parts being so constructed that the needle supporting element may be readily inserted in and removed from the knitting machine.

3. A needle bed for a knitting machine provided with needle walls between adjacent ones of which needles or jacks are adapted to slide, a

strip-like element offset between itsends, separate from the needle-bed, being frictionally held within a slot of the needle bed and between two mentioned walls thereof the parts being so constructed that the strip-like element may be readily inserted in and removed from the needle bed.

4. A needle bed for a knitting machine provided with removable needle walls between adjacent ones of which needles or jacks are adapted to slide; a strip-like element ofisetbetween its ends, separate from the needle bed, being frictionally held within 'a groove of the needle bed and between two mentioned walls thereof the parts being so constructed that the strip-like element may be readily inserted in and removed from between the two mentioned walls.

5. A bed for a knitting machine said bed having slots therein defining walls, elements seated on the outer edges of the said walls and beingfrictionally and removably retained therein and readily removable therefrom, needle walls removably seated within the mentioned slots and deflning, in conjunction with the mentioned elements, raceways for knitting instrumentalities.

6. A needle bed for a knitting machine having needle walls between which needles are adapted to slide longitudinally of the needle bed, a recess extending transversely of the needle bed and striplike elements offset intermediate their ends, such oifsets being received withinthe recess, the elements being retained in position in the needle bed by frictional engagement between the of!- sets and the walls of the recess, the said elements serving to support the knitting instrumentalities in their sliding movements the parts being so 5 constructed that the strip-like elements may be readily inserted in and removed from the needle bed.

7. A wire-like element adapted to be inserted ina knitting machine and act as a support for knitting instrumentalities, said element being offset between its ends to provide diverging arms for frictional engagement in a needle bed of a knitting machine.

8. A needle bed for knitting machines, said needle bed having needle walls between adjacent ones of which needles or jacks are adapted to slide, an element offset between its ends and separate from the needle bed said element being frictionally held within a slot of the needle bed and between two mentioned walls thereof, the parts being so constructed that the said element may be readily inserted in and removed from between the two mentioned walls, such construction of the parts including diverging arms defining the offset.
