- My present invention relates to, improvements in needle bars for fullfashioned knittin machines.

object of the invention'is' the provision of a needle bar construction having improved strength and a simple, rugged, strucr ture.

Another object is to provide a needle bar having a needle heel receiving and supportv ing opening which will accurately determine the position of the needles.

A further object is the provision of a simple and efficient method of manufacture of said needle bar. A

7 Other objects will appear hereinafter.

The invention consists in the features, combination, and arrangement of parts hereinafter described and particularly pointed out in the claims.

Referring to the drawings: 7

Fig. 1 is an end viewpf the needle bar. Fig. 2 is a front elevation of the-needle bar with the'clamping plates removed and the bolts shown in section. 1'

Fig. 3 is a front view of the needle bar on a reduced scale showing the clamping plates in place.

Fig. 4 is a view of the needle bar of Fig. 1 as it is when removed from the: mold and before it is finished and slotted.

In the drawings, 1 represents the body of the needle bar through which bolts 2 pass at intervals to threadedly connect with clamping plates 3 arranged side by side along he bar. I

The needle bar 1 is provided with a vertically grooved needle spacing portion or bar 4 at its upper end. The vertical grooves for spacing the needles are indicated at 4a.

' Beneath the needle spacing member 4 and in the'vertical face of the body 1 is provided a longitudinal groove'5 for receiving the heels of the needles6. The uniform groove and accurately formed, as compared to the separate pin holes heretofore formed in needle bars for receiving the individual needle heels. The separately formed holes were difiicult to make with accuracy as they 5 contributes to accuracy in that it is readily body 1 is cast around it in the flask.

The molding process requires no finishing of contacting surfaces and a more strong and massive united product results than by the screw connected finished surfaces in needle bars heretofore made.

. Preferably the needle bar body 1 is cast of aluminum while the needle spacing member 4 is preferably of brass. The clamping plate may be of drawn steel and is preferably provided with a facing 8 of pasteboard.

The needle spacing member is simply a drawn shape, preferably of brass, cut oil to length requiring no machining before the casting in the mold.

In Fig. 4 is shown the casting as it appears when removed from the mold in unfinished condition with the aluminum of the needle bar body cast around the brass needle spacing member. The casting of Fig. 4 is then machined and finished and provided with the vertical grooves or slots 4a in the needle spacing member, the body member 1 be1ng cut back beneath themember 4 and provided with the longitudinal groove 5.

The needle spacing member 4, if desired, may be extended downwardly so tha t the longitudinal groove 5 may be cut in 1t mstead of in the body 1.

I do not desire to limit my invention to the specific materials mentioned nor to the exact construction shown as it will be apparent that modifications may be made w thout departing fromthe scope of the invention as set forth in the claims.

I claim:

1. A needle bar for full fashioned knitting 10 2 neeaae machines including a loody of aluminum hav ing a needle spaclng loar of brass interlock ingly molded thereto, said body having an.

longitudinally extending groove loeneath said needle spacing heels ofthe needles.

2. A needle bar for full -fashioned hitting machines having a needle spacing bar molded thereto, said spacing liar being vertically grooved to receive the needles the said bar having a longitudinal groove in its vertical face to receive the heels of the needles bolts passing through the needle bar, and a series of adjoining clamping plates connected with said bolts to? clamping against. said needle spacing loar and needle loa-r 3. A needle bar for full fashioned machines oomprisng a member to space the needlesmolded with the body oi the loan to present a double face including an upper portion of one metal and a lower portion of adifferent metal, said double face having vertical needle spacing grooves therein and a longitudinal groove loeneatli said vertical grooves to receive the heels oiithe needles,

4:. A needle barter full fashionedlrnitting machines having a vertical face provided with a series of vertical needle spacing grooves and a longitudinal groove beneath the vertical groove to'receive the heels of the needles, said face comprising an upper "portion c of brass and a lower portion of aluminum,

1 said metals being molded together and having intimate contact throughout their contiguous surfaces. 1
