This invention relates to means for reading patterns for manipulating the punches for cutting jacquard cards for lace and other weaving. a I I .v v 7 An apparatus of the type to which my 1n: vention relates is illustrated'in the accompanying drawings in, which Figure l is a front elevation, Y

Figure 2 is a side'elevation, v Figure 3 is awrear elevation, and v v ure, 4 is a pla w of ch ma hi e,

a preferred form of my improvements, which will be hereafter described being shown in Figures 2, 3 and l. 7

Figures 5 and 6 illustrate to a larger scale Figures 7 and 8 areappended to illustrate more clearly the operation ot the type of apparatusto which my invention relates and Figure 9 illustrates'an improved needle whichwill also be hereafter-described;

. Referrin to the drawin 's:

needleswill now be described.

and 2). Each of said depressed keys preferably move; twohorizontal pivoted arms 4; and 6 (Fig. 7) clear of driving bars 11 and 7 respectively.

7 By means of treadle or other mechanism, F said drivlng bars are moved so asto co-ac't with and, move forward the arms which have not been, depressed thereby moving vforward the vertical bars 2 (Fig 7) secured thereto. Those bars act on intermediate needles-(l which in turn act on the cross needles D (Fig. 8), each of which is string or draw needle E. i r I The movement or" he cross needles D bring the hooked ends of the corresponding string needle E in the way or clear of the gridG; (Fig. 8).

As shown in needles E to which the strings are secured,

the number of the strings depending on the number of repeats in the. pattern, pass through a slotted plate I against which the: right. angled extremities of the 3 string needles bear.

In one type 0t which have been omitted in order to simplify the drawings and description of invenmachine, certain details of Figure 8, the ends of the; L

tion, thisplatel (Fig.8) would be'moved to the left, thereby permitting the needles E, which are not caught in the grid G, to

move in a like direction and operate the selepting needles in the selecting needle boX. Those selecting needles operate on the punches which are caught ina hand plate and the cards thereafter punched in the usual manner, all as will be readily understood by those skilled in the art.

In another type of machine, the grid G (Fig. 8) 'would be moved to; theiright.

carrying With same the string needles caught therein. The strings attached to the latter move SllQfi Spindles clear of the punches of l the punching machine.;., The other punches retained bythe spindles make the necessary punches in the cardi Here aga c r ain c tr t na tail-s ave not been shown, whereby the general dc;

scription otmyinvention" may be :Eacilitated. I

It is then necessary "to return the cross needlesD to their inner or normal position in order that the intermediate needles 0 may again act on, same tomanipulate the punches for the next card tobe punched and my present invention consists of im-- proved means 101' so doing, all as w ll 'appear more fully hereinafter.

AQCording to invention, 'afsplashboard is mountedopposite the ends of the cross needles remote from] the needles. and by automatically.actuated trip mechanism hereinafter describedisaidboard I is pushed inwardlysoas toreturnthe cross needles 7 D to their normal position. KThe boardis thereafter returned to its outer or intermediate.

normal position so that the cross needles I) may be 'actuated by the intermediate needles C. v

Said trip mechanism is preferably actu ated by the means' by which the string or draw needles E are returned to their normal position. The preferred construction of trip mechanism will nowbe described with reference to Figures 2, 3, 4L and 5 of the annexed drawings.

A splash board 12 is slidably mounted on bolts 13 carried by the box 1 1 containing the cross needles D. Helical springs 13 encircle said bolts and alwaysjtend toforce the said splash board 12 outward. Carried by brackets 15 also secured to said box 1 1' is an upright spindle 16 to which are rigidly secured an outwardly projecting arm 17 and a numberof cam or like "members 18 the faces of which bear against thesplash board 12.

. Carried by a bracket 28 of the framecontaining the slotted plate I is a pivoted arm 21, notched as at 22 and held in engagement spring 23.

l with the end of the arm 17 by means of a 24 is a fixedpin secured to the machine frame A.

The machine illustrated in Figures 1 to 4 is of the type 'in'which the plate I is, by means of rods 27 (Fig. 1), moved to the left by treadle or like mechanism actuated by the operator in charge of the punching machine, thereby permitting the needles E which are not caught in the grid G to move in a like direction to operate. the selecting needles in thejselecting needle box. lVhen the punches heretofore mentioned have been caught in the hand plate, the plate I (Fig. 8) is moved to the right to itsnormal position. The action of the trip mechanism is as follows When the plate I is moved to the left the .hotched arm overrides the end of the arm 17,

being" held inv engagement therewith by means ofthe spring 23. On the return movement the notch 22 coming in contact with the arm 17 turns same and thereby also thespindle 16 and cam members 18 which latter, acting on the'splash board, moves same inwardly, thereby returning the cross needles .to their normal position. Before the end of the return stroke the arm 21 coacts with the pin 24 which results in the notch 22 being freed from the arm 17 This permits the splash board 12 to be moved outwards under the action of the springs 13 so thatthe cross needles can be again actu-- ated.

The chain dotted lines in Figure 5 indicate --the position of the trip mechanism just before the notch 22 is freed from the arm 17 and the full lines indicate the normal position of the mechanism. r

Preferably a hand lever 27 is also rigidly V secured to the spindle 16. By moving this lever as indicated'bythe arrow the operator can immediately return all cross needles to their normal position should he find an error has been committed in operating the keys 1.

The mechanism indicated in Figure 6 is substantially similar to that in Figure 5 with the exception that the notched arm 22 is carried by a bracket 29 secured to the connecting rod 26. This arrangement is suitable for use in the automatic type of punching machine in which the punches are normally prevented from moving by short spindles secured to the string needles.

Said connecting rod 26 is connected to the grid G and punching machine in such manncr that when it is moved to the left (the pivoted arm 21 then overriding the arm 17) the grid is moved to the right to operate the said short spindles.

After the card has been punched said rod is movedto the right returning the grid to its normal position and also causin'g the notch 22 to co-act with the arm 17 and thereby return the cross needles as herein before described. v

Also in such automatic machines of the type hereinabove set forth, I preferably provide means whereby, when a number of repeats are required to be punched, the grid Gr (Fig. 8) is kept in its outer position, i. e.,

' the position in which theselecting needles mentioned automatic type of machine, said shafts would slide in their bearings to actushafts are stationary but in'the previously ate the grid G. The said catches are actuy -ated by the operator, who, when the re quired number of repeats have been punched, Withdraw same and thereby permits the grid G and cross needles D to return to the nor mal position, when the cross'needles Dniay again be acted on by the intermediate needles O.

Instead of two catches as aforesaid a catch or catches engaging any part of the grid actuating gear may be employed.

The arm 17 is preferably provided with an extension 17*, see Figure 2, which pro jects below the arm 21. The latter always rests 011 and is guided by said extension-dun ing its reciprocatory movement.

Preferably the cross'needles D used in combination with the said trip mechanism are of an improved construction. I

As shown at Figure 9 said needles are bent backwards at their outer end, the bent back portion being provided with notches d.

In thein inner; or, normal position the, outer,

notch is .engagedv by the slotfied: plate J of th needle box, 14,. and. when moved out-i wardby the. intermediate needles, the second notch thereon, engages with saidplate.

Those; notches preventaccidental displacement ofthe needledue to, vibration or other cause. 1

In Figure 2 the lower cross needles are shown in the outer position and the upper needles in their inner position.

Preferably the other end of said cross needles are provided with ferrules d1 which the language thereof, when read in connection with the prior art, regardless of the details and functions mentioned-in'the description or illustrated in the drawings.
