The parts just described are common to many well known looms and, by themselves, form no part of the present invention. In the simple forms of such looms it is common to employ eight heddle frames and the invention has been shown in these figures as applied to a loom having this number of heddle frames although it will be obvious from what follows that it is by no means restricted to any particular 'numbenof' "frames when used in a dobby or other like loom.

As shown in connection with the loom here illustrated a bracket ll of L-shape is supportedon top of the loom frame ID at the lefthand end thereof and is held braced by suitable braces l8. Solenoids l9, equal in number to. theframes H are butted against the vertical leg of the bracket,

and have shanks 20 which"e'xtend through this leg so that nuts 2| may be screwed-.on-these shanks to. secure these solenoids in place. Each of thesesolenoidsyis provided with a core 22 whereto' the harness cords Hot a; respective frame H are fastened and each core projects through a respective stem; the stems being tublrlar, and has an adjusting nut 23 screwed on its outer end so that the drop of the frames I I- when, the solenoids are de-energized may be regulated.

The roll' actuated circuit-closers are'shown in Figures 1 and 2m their general relation to the loom and are also shownin detail in FiguresBj land 5. In this part ofthe invention there" is provided a housing 24 having slots- 25 in its end walls to receive the journal ends 260i a roll 21. As here shown'this roll or cylinder 2T-is provided with a series of sets of circumferentially spaced holes adapted to, receive contact actuating pegs 29 selectively" and thereis providedat least one set of these" holes for each of, the frames H and its solenoid l9. One of the'jojur nals 26 has fixed thereona gear 38 which, when the roll'is dropped into place, meshes with a gear 3| wherewith, is associated a sprocket- 32 connected-by a chain 33* with a sprocket fixed on the main shaftJS; Thus the rollrotates in timed relation to the main shaft and", since the entire loom is actuated from this shaft, the roll rotates in timed relation "to the movementsof the shuttle so that, .as will" be presen-thyunderstood, the shed is opened just prior to the pick of the shuttle in throwing the weft; 1Journalled in the ends of the'housin'g isa bar 35 preferablyof insulating material." This bar is' arranged torotate in said housingends, and-i's held inf'ad justed position by-nuts36r-On top of this bar is fixed a series of spring contacts 31* preferably termed the movable contacts and equal in; number to the sets of holes 28.. Below-eachof these contacts is a second spring contact 3 8"whichare termed the fixed contacts." Each contact 31- has mounted on its free end a strikerfpiece' 36a wherewith a peg or pin 29 placed-in one'of the corresponding sets'of-holes 28' engages asthe roll is rotated. Thus the contacts 31-, are closed onfthe contacts 38 selectively. Each contact -31 is connected by a wire'39. with one terminal of a'respective solenoid 19 while the re'mainingterminals of the solenoids are connectedinmultipleto'a current supply line,4fl; Similarly; the contacts 36 are connected in'multiple to a secondsupply line 4!. By tilting the bar 3'5 to'a suitable angle-by loosening the nuts '36"the time *the contacts 31 remain closed on the contacts 38 may" be reg-u:- l'ated'since by this'm'eans the pins 2.9'will remain in engagement with and depress thev contacts-31- a greater or lesser'time.

Now, by properly positioning the pins 29 in the holes 28 the contacts may be closed in any desired order. As each contact is closed a circuit will be established through the solenoid controlled by that contact and the corresponding harness or heddle frame will be raised and the shed formed by lifting the desired group of warp threads controlled by that heddle frame. Thus any desired pattern capable of being worked on the particular loom may-be formed. J

At times it maybe desirable to' weave a pattern too long to be controlled by the number of holes in one set of the holes 28 extending circumferentially around the roll since, obviously,

" after the'roll has made a complete rotation there will'ibe. arepetition of the pattern pegged out on that rollin the arrangement above mentioned.

In order "to'provide for a greater number of -picks before a repeat than is possible under these maybe'used.

"As shown in Figure 8 several of the rolls 21 maybe mounted cnthe same shaft each'associated with its set of contacts 3'! and 38 maybe used. In this case one terminal of each-solenoid t9 has connection with corresponding contacts 31 of the several sets in multiple by wires 39a while the remaining terminals'of the solenoids are connected in multiple to the line wire'40 as before. The line -wire 4| in thiscase is connected to a wiping contact 42 which bears on a conductive disk 43 rotated from the shaft of the rolls '2'! by gearing 44. An insulating strip 43a extends aroundpart of the periphery and spaced around the periphery are wiping-contacts 45- each 01- which is connected to allof the contacts 31 of a respectiveset by a wire 46. The upper wiping contact 45 as shown in Figure 8 is engaged with the electrically charged disk 43 throughthe positive line' wire 4|. This position of the disk,- as will be observed, governs the positive side of the contact opposite the left hand cylinder 2l,-and assuming that the first pairof contacts 38 were depressed, positive current would be caused to fiow'from itssource through line wire 4| ,contact 42, upper wiping contact 45 and through the contact 38 to a solenoid l9 for'return over-the negative wire'40; When the disk 43 is rotated to place the lower wiping contact in electrical engagement'with the disk, positive current will be caused to flow from the source'throug'h line wire'4l, contact 42, disk 43;'lower brush 45-and wire 46' to furnish positive current to any one of the contacts which might'be closed on the right hand cylinder Z'Iand should any one of the contacts 38' be closed for engaging the contact 31, 'this'positive current wouldfiow through a coil I return over wire 40.to the negative side of the source of supply of. electrical energy.

In the form. shownin Figure 9 spiders 46 are mounted on a shaft 41 and, driven by Geneva gearing 48 suitably actuated by gearing (not shown) from the main shaft. The rolls 2'! are journalledin the ends of these spiders and the gears 30 of these rolls are thusbrought successively into mesh with the gear 3| and in position to actuate the contacts-31 to close on the contacts 38'.

ln-the-form shown in Figure 10 the rolls, are replaced by an endless chain of bars 49. having holes 50 and pins or pegs 5| .similar to the ,holes and pins'of the rolls and arranged torselectively conditions several devices now to be described The chain is supported on suitable toothed 52 driven by suitable gearing (not shown) from the main shaft of the loom.

With any one of these arrangements a pattern covering any practical number of weft picks may be arranged for before a repeat.

In Figure 11 is shown an arrangement of solenoid for a jacquard loom wherein the solenoid I90. is disposed vertically and heddle wires 53 are connected directly to the core 22a. Obviously, although but a single solenoid is here shown, a number of such solenoids will be employed nested as closely together as is practicable and the core of each solenoid will have a selected group of heddle wires carried thereby so that complicated patterns may be formed by this means just as with the well known cards of a jacquard loom.

It will be seen that, by means of this invention a much wider variety of patterns may be obtained from an ordinary dobby loom with mechanical head works. Furthermore, the head works and harness of a dobby loom may be replaced by solenoids and heddle wires as in Figure 11 and such a loom readily converted into a loom of the jacquard type.

There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

It is obvious that many minor changes may be made in the form and construction 01' the in- I vention without departing from the material principles therein involved. It is not, therefore, desired to confine the invention to the exact forms herein shown and described but it is desired to include all forms which properly come within the scope claimed.

What is claimed as new is:-

In a loom or the like, a series of heddle actuating solenoids, a circuit for each of said solenoids including a normally open circuit closer, said circuit closers each consisting of a fixed contact and a movable contact and being arranged in abank, a roll positioned parallel to the bank of circuit closers and provided with a series of sets of circumierentially spaced holes, each set being alined with a respective circuit closer, and pegs selectively positionable in said holes and engageable with the movable circuit closers to close them on the fixed circuit closers whereby to efiect selective energization of said solenoids, a second similar roll, said rolls being mounted to move bodily, into and out of position to actuate the circuit closers, means to effect movement of the rolls successively into circuit closer actuated position, and means to drive the roll in such position.
