Specification of Letters Patent.

Patented June 8, 1909.

To all whom it muy concern:

Be it known that l, WALTER J. GARLIox, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and lmproved Loom, of which the following is a full, clear, and exact description.

The invention relates to box looms and its object is to provide a new and improved loom having a plurality of shuttles carrying different colored threads, and arranged to permit moving any one of the shuttles into active position desired number of picks according to a predetermined design.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of the improvement; Fig. 2 is a side elevation of the same Fig. 3 is an enlarged sectional side elevation of the improvement on the line 3-3 of Fig. 9, and showing more particularly a shuttle box, means for shifting the same, and part of the stop motion; Fig. 4 is a like view of the same showing the parts in a different position; Fig. 5 is an enlarged sectional elevation of the lay shaft and part of the shuttle box shifting mechanism; Fig. 6 is a cross section of the loom on the line 6-6 of Fig. shiittle boxes on the ends of the lay; Fig. 8 is an enlarged plan view of the shuttle box and the operating mechanism for the same on the right hand side of the lay; Fig. 9 is a front elevation of the same; Fig. 10 is an enlarged side elevation of the shifting mechanism for the shuttle boxes; Fig. 11 is a plan view of the same, and Fig. 12 is a cross section of the same on the line 12-12 of Fig. 10.

On the main frame A of the loom is mounted the usual crank shaft B connected by pitmen O with a lay D, and on the said crank shaft B is mounted to rotate loosely a pulley E connected by a belt E with other machinery for imparting a continuous rotary motion to the pulley E, the motion of which is transmitted to the crank shaft B by the usual clutch mechanism Ezjunder the control and working it for one or any 2 Fig. 7 is a sectional plan view of the of the operator and also automatically controlled by the stop `motion to stop the loom in case of accident, as hereinafter more Vfully explained.

The swords D of the lay D are attached to the lay shaft D2 journaled in the main frame A, and on the ends of the lay D are arranged longitudinally extending bearings D3 on which are mounted to slide the shuttle boxes E and F', each having a plurality of compartments or pockets; for instance, as shown in the drawings, the shuttle box E is provided with com artments F2, E3, and the shuttle box E with compartments F, F5. When the loom is constructed with the shuttle boxes F, E', having each two compartments or pockets, as shown and described, then three shuttles G, G', G? are employed, the shuttles carrying bobbins provided with different colored threads, and the shuttles are adapted to travel from one shuttle box tothe other over the usual shuttle race D4, mounted on the lay D, the shuttles being actuated by the usual picker sticks H, H. Now by the arrangement described one of the compartments in a shuttle box is em tied and is in register at the time with the s iuttle race D, and a shuttle in the other shuttle box is in register with the shuttle race D4, to permit of sending the shuttle over the race-way into the empty compartment. Thus, as illustrated for instance in Fig. 7, the compartment F4 is empty and in transverse alinement with the shuttle race D, and the shuttle G inthe compartment F2 is in alinement with the shuttle race and consequently with the empty compartment E, and when the icker stick H is actuated then the shutt e G s sent across the shuttle race D4 through the open shed into the empty compartment F4. Now according to the predetermined design, the shuttle G in the compartment F4 may be returned at the next pick, but if the pattern of the fabric should `require another color for the next ick, then the shuttle box F is shifted lateral y, so as to bring the compartment F5 and the shuttle G2 in register wit the race-way D4 and with the picker stick H', to allow the latter to send the shuttle G2 over into the empty compartment F2. Now this shuttle G2 may be returned back to the compartment F5 if a pattern calls for it, but, if not, this shuttle G2 may be kept in the compartment F2 and the shuttle box F shifted laterally, so as to bring the compartment F3 and the shuttle G in register with the shuttle race D4l and the picker stick H, to allow the latter' to send the shuttle G over the race-way DAl and through the open shed into the empty com artment F5. Thus from the foregoing it will that any one of the shuttles can be passed to the other side during one pick and another shuttle returned in the next following pick, or any one of the shuttles can be sent forward and backward as many times as desired and called for by the pattern.

By reference to Figs. '7 and S, it will be seen that the outer ends of the compartments F2, F3 in the shuttle box F, and the compartments F", F5 in the shuttle box F are connected with each other, that is, the outer ends of the shuttle boxes are open, to allow shifting of the shuttle boxes in a lateral direction, to bring the corresponding compartments in register with the picker sticks H, H and the shuttle race D4. In order to impart the desired 'sliding motion to the shuttle boxes F and F the following shifting mechanism I is provided and controlled by a dobby or jacquard J of any approved construction: he rear sides of the shuttle boxes F, F are pivotally connected with bell crank levers K, K fulcrumed on the lay D and pivotally connected with downward extending links K7, K3 connected at their lower ends with links K4, K5 mounted to slide in recesses in the lay shaft D2, as illustrated in Fig. 5. The lower ends of the links K4, K5 are pivotally connected with arms K, K7, of which the arm K7 is secured on a transversely extending shaft K8 ournaled in suitable bearings on the main frame A. The arm K6 is fulcrumed loosely on the shaft K8 and is provided with an upwardly extending arm K9, and a similar arm K10 is secured on the shaft K8 adjacent to the arm K9. The arms K and K10 are connected by links K11, Kl2 with the cross heads I, I2 of the shifting mechanism I, the cross heads I, I2 being mounted to slide longitudinally in suitable bearings arranged on a bracket A attached to the main frame A at the right hand side of the machine. The cross heads I, I2 receive a longitudinal intermittent sliding movement by the use of wheels L, L mounted to rotate loosely on a shaft L2 held on the bracket A, and the said wheels L, L are adapted t0 be turned intermittently and independently one of the other by hook levers N, N both fulcrumed on a bell crank lever O fulcrumed on the main frame A and engaged by a cam O secured on the crank shaft B, the said bell crank lever O being held in engagement with the peripheral surface of the cam O by a spring O2, as plainly illustrated in Fig. 2. The hook levers N and N are normally held out of engagement with the wheels L, L by springs N 2 which connect the hook arms N with the bell crank lever O, and the rear ends of the be seen hook levers N and N are connected by springs N3, N4 with arms N 5, N 6 fulcrumed on the main frame A and connected by chains I), F with arms I, P mounted to turn on a shaft P and connected in the usual manner with the dobby J, so that the chains l and IJ are pulled upward according to the pattern called for by the dobby J. N ow when a chain P or P is pulled upwardly then a like upward swinging motion is given to the corresponding arm N 5 or N which by the spring N3 or N 4 imparts a swinging motion to the hook lever N or N, so as to swing the saine with its hook end into engagement with the corresponding wheel L or L, to give the latter a quarter turn. Now when this takes place a corresponding sliding motion either in a forward or a backward direction is given to the cross head I or I2, which by the action above described shifts the shuttle box For F to bring the desired compartment into alinement with the shuttle race D4 on the lay D The shifting device I is constriu-.ted in detail as follows: Each of the wheels L, L is provided on one face with diagonally diss posed pins L3, L1 and on the opposite faro with correspondingly disposed pins L", L, and each of the cross heads I, IE is provided with a longitudinally extending top bar I" and a bottom bar I4, having notches l, I for engagement by the pins L5, L and L3 and respectively. Each of the wheels L, L is provided at the corners with projections L7 adapted to be engaged by the hook end of the corresponding hook lever N or N for giving a quarter turn to the corresponding wheel L or L. N ow when the several parts are in the position illustrated .in Fig. 1() and the hook lever N is caused to swing downnanwl by the action of the dobby J and a continuons bodily reciprocating movement is given to the said hook lever N by the action of the bell crank lever O and the cam wheel O, then the hook end of the hook lever N in engaging the forward projection .L7 of the wheel L turns the latter, on the rearward reciprocating movement of the hook lever N, so that a quarter turn is given to the wheel L. N ow as the pin L5 of the wheel L is in engagement with the corresponding notch of the up )er bar I3 of the cross head I, it is evident tlliat on the turning motion of the wheel L, a rearward sliding' movement is given to the cross head I in the direction of the arrow (1,. During this turning movement of the wheel L the pin L4 in engagement with the notch l in the bottom bar I4 moves out of the notch, to allow a free, sliding movement in a rearward direction of the cross head I. When the hook lever N reaches the end of the stroke then the pull on the hook lever N by the dobby is released, so that the spring N 7 returns the hook lever N to its normal position, and consequently when the hook lever N lll( moves bodily forward by the action ofthe bell crank lever O and the cam O', it is evident that the wheel L remains at a standstill. Now, presuming that the above-described operation is repeated, that is, another quarter turn is given to the wheel L by the hook lever N in the manner described, then the pin L5 of the wheel L on account of having previously moved in engagement with the notch I5 in the bottom bar I4 of the cross head I', shifts the latter in the inverse direction of the arrow a', that is, back to the position shown in Fig. 10. Thus from the foregoing it will be seen that by the hook lever N the cross head I' is reciprocated intermittently, and in a like manner the cross head I2 is intermittently reciprocated by its hook lever N' In order to lock either of the cross heads I', I2 in the end positions, a catch Q is provided, adapted to engage notches I7, I8, formed in the under side of the bottom bars I4 Vof the cross heads I' and I2. The catch Q is fulcrumed at Q' on the bracket A', and is provided with a downwardly extending arm Q2 ressed on by a spring Q2, to hold the catch 1Q in engagement with either of the notches I7 or I2, to lock the corresponding cross head I' or I2 in the end position. The catch Q is provided on its top with an offset Q1 adapted to be engaged by a rearward lower projection L7 of the wheel L or L', to move the catch Q out of engagement with the corresponding notch I7, I8 immediately previous to giving a reciprocating motion to the cross head I' or I2 by the wheel L or L', as above described. It is understood that when the cross head I' or I2 is shifted, a corresponding shifting motion is given to the shuttle box F or F' for the purpose previously mentioned.

The stop motion for shifting the clutch' mechanism E2 out of gear is of the usual construction, and is actuated from whatever shuttle compartment and corresponding shuttle may be in active position at the time. The actuating mechanisms for the stop motion are alike for both shuttle boxes F, F' and hence it sufli ces to describe but one in detail, special reference being had to Figs. 3, 8 and 9, which show the actuating mechanism in connection with the shuttle box F. Into the compartments F2, F3 (F2, F5) extend lengthwise the shuttle retainers R, R' in the form of arms pivoted on the shuttle box F (F') and pressed inward into the path of an incoming shuttle by springs R2. The free ends of the retainers R, R' are adapted to engage spring-pressed levers S, S' fulcrumed on the shuttle box F (F') and adapted to actuate bell crank levers S2, S3 fulcrumed on opposite sides of the lay D and connected with the forked upper ends of another set of bell crank levers S4, S5 likewise fulcrumed on theV lay and pivotally connected with an armT' projecting rearwardly from a shaft T extending transversely and journaled in suitable bearings on the front of the lay D, as plainly indicated in the drawings. The shaft T is pressed on by a spring T2 and is provided with forwardly extending arms T3 adapted to engage bars U' mounted to slide in the frame A of the loom below the breast beam A2, as plainly indicated in Figs. 1 and 2. The bars U are adapted to engage the hand levers U2 of the stop motion U and connect with arms U3 attached to the stop motion shaft U2 journaled on the front of the main frame A, so as to connect the two hand levers U2 on opposite sides of the main frame with each other. The hand lever U2 on the left hand side of the main frame A is connected at its lower end at U5 with the shifting arm U5 for the clutch mechanism E2, to move the clutch mechanism E2 in and out of gear with the pulley E. The arms Tx extend normally in the path of the bars U owing to the action of the springs T2 on the shaft T, but when a shuttle passes properly into a compartment F2, F2, F4 or F5 and the extending retainer R or R' is pressed outward by the incoming shuttle, then the spring-pressed lever S or S' receives a swinging motion by the said retainer R or R', and the lever S or S imparts a swinging motion to the corresponding bell'4 crank lever S2 or S2, which in turn imparts a swin ing motion to the corresponding bell crank ever S4 or S5, and as both bell crank levers S2 and S5 are connected with the arm T', it is evident that a swinging motion is given to the latter, to turn the shaft T, with a view to swing the arms T3 downward out of the path of the bars U', and hence when the lay D beats in, the arms T2' do not come in contact with the bars U', and consequently the stop motion U is not actuated. In case, however, a shuttle does not properly pass into the corresponding compartment F2, F2, F4 and F5, then itr necessarily does not actuate the spring-pressed retainer R or R' and the shaft T is not rocked, and consequently the arms T3 come in contact with the bars U' as soon as the lay beats in, and when this takes place the arms T3 push the bars U' outward, thus moving the hand levers U2, whereby the shifting lever U5 is actuated and the clutch mechanism E2 is thrown out of gear with the pulley E and the loom comes to a stop before serious damage can be done. From the foregoing it will be readily seen that whatever position a shuttle box F or F' takes, it is in position to actuate the stop motion in case a shuttle fails to pass from one shuttle box over the shuttle race D2 to the other shuttle box.

Now when the loom is running, the shuttle boxes F and F are automatically shifted by the mechanism described, according to the predetermined design to be woven in the fabric and translated by the dobby J. It will be seen that by the arrangement described, each and every one of the shuttles can make one, two, three, four, iive or any desired number of picks, that is, it is not necessary for a shuttle to make two picks before another1 shuttle can take its place, but each shuttle can make one or any desired number of picks.
