E. PFENNINGER I ADJUSTMENT FOR EMBROIDERING MACHINE NEEDLES Filed Sept. 9, 1921 if? Z6 :15

"a? 12 I I! 2??? n L 10 1 1 135 I 29 "Q V 1Z fi/ imlmnmmm actual practice, is from thirty to forty-"five feet in length, it would be a laborious proc ess to shift the individual needles in or out, and to obviate this I provide the bar 31,

.which has a plurality of regularly spaced transversely therethe rail 10, are driven through the bar so that their unheaded ends will project from the corresponding face of. the bar. The bar is then appliedto the blocks 14:,with the said. projecting ends of the screws 32 within narrow grooves 34 of the blocks, and moved,

bodily, in a direction toward the outer edge of the rail 10, with the result that the de-' sired needles are projected from the rail, into operativeposition. -l 'he other screws 38 are properly adjusted, in the same man-- ner as the screws 32, but at different intervals, so that other groups, or needle blocks, at corresponding intervals, may be moved in; or out. By thisarrangement, it is possible to project the needles at the desired intervals for producing the stitching necessary for the embroidered. design. This is clearly shown in Figures 4 and 5, the former showing the bar in operative position, while the latter shows the bar in fragmentary perspective view. A

By this construction, when it is desired to use certain needles and discontinue the use of the remainder thereof, those which are not to be used are positively held in such position as to offer no interference.

3V hat is claimed is:

1. An embroidering machine needle device including a main block having a plurality of transverse grooves in one face,'

needle holding blocks slidable grooves and each havmg a groove in its upper face, "the main block having a longi tudinal groove in its upper face intersecting in said the transverse grooves, and a locking bar" slidable in the longitudinal groove and havmg projections "on its lower face for engagement in the grooves of-the needle blocks to hold the blocks against movement in the:

transverse grooves.

2. An embroidering machine needle" =de{ vice including a main block having a plurality of transverse grooves in one face and a longitudinal groove in its upper face ad jacent one edge thereof and a longitudinal opening ad acent the opposite edge',sa1'd longitudinal groove and-opening intersecting the transverse grooves, a needle block slidable in each of the transverse grooves and having transverse grooves in its upper and lower faces adjacent its opposite ends respectively andadapted for alignment with the longitudinal groove and opening respectively, a locking barslidable in'the lon gitudinal groove and having transverse pas sages in itslower face resulting in intermediate projections the. latter being ar ranged to enter the upper grooves of the needle blocks, and'a locking bar slid-able inrsaid opening and havingtransverse passages resulting in intermediate projections arranged to enter the, lower transverse grooves of the needle blocks.

In testimony whereof, I affix my signa-
