HERMANN BUSCHER, or LANGERFELD, NEAR BARMEN, GERMANY, ASSIGNOR TO MAX HEnKnns, on NEW YORK, N. Y.

LACE-BRAIDING MACHINE.

Application filed January To all whom it may concern.

Be t known that I, HERMANN' BUsoHER, a

citizen of the German Empire, residing at Langerfeld, near Barmen, Germany, have invented certain'new and useful Improve;

ments in Lace-Braiding Machines, of which the following is a specification."

My invention relates to a lace-braiding machine in which the bobbin-carriersfeanbe arrested by being withdrawn from thecon stantly rotated drivers and looked in ienlargements of the bobbin-traclgjsaid enlargements being usually formed at the crossings of the bobbin-track by partly 'removingcertain points of thetrack-plate. It specially refers to a braiding machine of the type de scribed and claimed in my prior PatentNo. 1,034,688, in which a patterngear oontrolled rod is arranged, said rod being movablefup and down and projecting above the track plate. Belowv the track plate a so-called bobbin-withdrawer is mounted on the rod consisting of a guide-member adapted, when the rod is lifted, to guide a bobbin-carrier into an enlargement of the bobbin-track and to lock it there, whereas to the upper end of said rod a pawl-like member is linked which, on the descent of the rod moves out laterally .andpresses against the upper guidedisc of the bobbin-carrier, thus pushing the latter back into the bobbin-track within the reach ofthe drivers. In this known machine the guide' of bobbin-carriers which are intendedto passfthe crossings of the bobbin-track without being arrested is'a somewhat defective one because of; the missing, points of. the track-plate. The object of my present improvements is therefore to more perfectly guideithose bob bin:carriers by so constructing the aforesaid pawl-like. member that it performs the office of the missing track-plate point" when the pattern gear controlled rodfto which said memberand also the aforesaidIbobbin-with drawer are attached is lowered. According to my invention a substantially triangular plateis arranged on theupperside of the free end of thepawl-like member, said plate beinga'd'apte d tolco-act with the stem of a bobbin-carrierfand thus to guide the latter securely past the enlargement ofithe bobbin track. Other features of my invention appear from'thefollowing description setting forth more fully my improvements withreference to the annexed drawings, in Wh C 2,1923. Serial No. 610,472.

Figs. 1 and 3 are plan views of a part of a lace-braiding machine of the type referred to, V

' Fig. 2 is a sectional elevation on the line 2+2 of Fig. 1, and

Fig. 4 is a sectional elevation H. of Fig. ,3. r

The plates 5, b are as well known in the art laid out in a circle. They are positioned in recesses of the track-plate a, which forms thejouter curvature of the bobbin-track. The latter is,.as clearly shown in Figs.- 1 and 3, composed'of two undulary tracks crossing each other between two adjacent plates 6, b. Below the plates 6, b the drivers on the line rotated, the one to the left, the other to the right, impart motion to the bobbin-carriers ,g first in the one direction and then inthe other depending on the particular driver by which a bobbin-carrier is driven. Alternately 011 the inner side and outer' side of the bobbin-track there are provided at the crossings of the latter tongue-switches g, which serve, in a well-known manner for directing the bobbin-carriers according to the braid to be produced. Opposite each tongueswitch 9 the track-plate points normally projecting in between two adjacent plates 22, b is terminated so as to form an enlargement of the bobbin-track in which a bobbincarrier may be arrested. Below each blunt track-plate point a so called bobbin-withdrawer-d is provided. The latter possesses at its end facing the bobbin-track a guide rail fiwhich, when the withdrawer is in its lifted position, engagesthe downwardly projectingpin g of a bobbin carrier and leads the latter into the enlargement of the bobbin-track. In this way the bobbin-carrier is withdrawn from the drivers and arrested see rightkhand part'of Fig. 1 and left-hand part of Fig.2).

V Eachibobbin-withdrawer d is mounted on a vertical rod z'guided in co-aXia-l borings of the lower plate It and of the track-plate a. A coiled spring k surrounding the rodc' tends to hold said rod in its uppermost posi: tion in which an abutment-ring m. fastened to the rod bears against the underside of plate 72.. With the lower end of the rod 6 a tie rod of the pattern gear (not shown) is connected so that the rod, in a well 'known manner, may be pulled down by means of the pattern-gear, The upper end of the rod 2'- 0, care arranged, which, being continuously which projects above the track-plate a has an arm n attached to it, to. which is. pivoted a pawl-like member 0, resting with its free end 0 on the track-plate a just behind the upper guiderdisc 9 of a bobbin-carrier arrested at the corresponding track-plate point. On the descent of the rod 2' said pawl-like member 0 moves out laterally and, pressing against the guide disc 9 pushes the arrested bobbin-carrier back into the track within the reach of. the drivers 0, 0. See left-hand part of Fig. 1 and right-hand part of Fig. 3.

According to my invention a substantially triangular plate 7" is arranged onthe upper side of the free end 0 of the pawl-like member 0, said plate 1" being so shaped that it performs the oflice of the missing trackplate point when the rod 2' is lowered and the pawl-like member 0 moved out laterally (see Figs. 3 and 4;). It may thereby, as shown, be fastened to the pawl 0 by screws or the like or form an integral part of said pawl. The plate 1*, being adapted to" co-act with the stem g of a bobbin-carrier, serves to guide those bobbin-carriers which are intended to pass the crossings of the bobbintrack without being arrested. To this. end the rod '5 with the bobbin-withdrawer d is lowered before the downwardly projecting pin g of a bobbin-carrier can engage the guide-rail f of the withdrawer (Z. Thus, on

, the one hand, the arresting of the bobbincarrier approaching the crossing of the bob-- bin-track is avoided, while on they other hand, the bobbin-carrier is by means of the triangular plate 7" securely guided past the enlargement of the bobbin-track. In order that the upper guide-disc g of the bobbincarrier'may not run against the pawl-like member 0,. the free end of the latter is, on its underside, provided with two outwards ly and upwardly inclined faces 39 p so that the pawl 0 may be lifted by the guide disc 9 of the bobbin-carrier while said guide disc slides underneath the pawl -0. By this means I am not only enabled to provide for a sufficiently broad working face at. the free end a of the pawl 0, but I may, at the same time, somewhat shorten the triangular plate a so that, on pushing an arrested bobbin carrier again into the path of the drivers the point of said plate 1" does notcontact the stem g of the bobbin-carrier. Consequently the restoring of an arrested bobbin-carrier to the track is effected by the broadened free end 0 of the pawl 0 only, thus avoidng 1 1 16 Wear of the point of. the plate a". On guiding thosebobbinsintended topass the, crossing of, the bobbin-track without be,-

ing arrested, the shortening of the plate 1" is compensated by the lifting of the free end of the pawl 0 which causes a somewhat larger lateral movement of the latter.

restricted to the exact construction as shown on the drawings for many alterations or variations may suggest themselves to those skilled in the art without departing from the spirit of my invention. as pointed out in the'claims;
