HERMANN BAADER, OF GELTERKINDEN, SWITZERLAND.

LOOM SHUTTLE-MOTION,

ziois,eofi..

To UU e/:ioiib 'it may concern Be it known that l, HERMANN Baannn, a citizen of the Swiss Republic, residing at Gelterkinden. Basel, Switzerland, have invented certain new and useful Improvements in Loom Shuttle-Motions, ot which the Yfollowing; is a specitication.

This invention relates to looms and more particularly to the shuttle-operating mechanism and has :for its object the provision of a mechanism which is simpler' in construction than those heretofore used, which provides wider gaps 'tor the webs and greater travel 'tor a given length oit' shuttle.

Further objects are to provide a meehauism which is capable ot being' operated at higher speed than those heretofore used without injurious effect., whereby the output oli the loom may be largely increased.

The novel teatures o'l the invention will be apparent `from the following` description taken in connection with the drawings, in which,

Figure 1 is an elevation et a portion oit a loom embodying my invention; Figi'. Q is a transverse section on the line 2--2 oil Fig. 1; Fig. 3 a transverse section on the line l-B of Fig. 1; and Fig. Lit is a detail perspective view ot one of the actuating arms for the shuttle.

The invention' comprises the usual hatten l0, to the back ot which are secured the brackets 1l which support the shuttle races 1Q ttor the shuttles lil and the `guide 1st; :t'or the shuttle carrier 15. A recess 16 is formed in the rear side of the hatten 1 0 and receives the guide 17 for the shuttle carrier 1S, and also the plate 19. One end oitthe shuttle carrier 18 is provided with an outward projection 20 to which is connected one end of the bridge member 21, the opposite end of this bridge member beingsecured to the shuttle carrier 15. Any suitable mechanism for reciprocating the shuttle carriers, such as the

straps

22 and 28 which pass over

pulleys

24, 25 and Q6 and are secured to the shuttle carrier 1S, may be provided. It will be seen that the bridge member 21 causes the shuttle carriers to be actuated together.

The shuttle carriers are provided with pairs of arms 27 and Q8, these arms being pivoted to the shuttle carrier at the points 29 and provided with laterally projecting pins 30, provided with suitable anti-friction rollers which engage the cam tracks 31 and Specification of Letters Pateut.

Patented Feb. 27, 1912.

Application filed October 30, 1911. Serial No. 657,524.

l 32, arranged in pairs. lhese cam tracks are termed in the side ot the plates 19 and 33, which are secured respectively to the guides 'I7 and ll.

Referring to Fig. 1, it will be` seen that the shuttle at the lett hand side of the figure is engaged b v the arm 27, the arm passingthrough an eye tilt in the end of the shuttle. The arm 2S. it will be observed7 is out o1 engagnment with the eye at the opposite end ot the shuttle so that'. as the carriers are moved toward the right the shuttle referred to Ywill pass through the space A and into the shuttle race to the right thereo'l. The cam track 32 is provided with a curved portion 'lt' which is adapted to swing the arm "2S into engagement with the eye 35 as soon as the right hand end of the shuttle has passed over the space A. lt will also be observed that the cam track 32 to the right ot' the curve Sti is straight so that the arm will remain in engagement with the eye 35 as the shuttle continues to the end ol its movement in the racc to the right of the space lt will also be observed that Jthe cam track 31 has a curved portion 37 which will cause the arm Q7 to swing out oit engagement with the eye 3l as the shuttle leaves the shuttle race to the le'lt of the space A.

lVhen the shuttle carriers move to the left the operation ot the arms 2T and 2S will be the reverse of that 'j ust described and it will, therefore, be seen that the shuttles are at all timesl moved positively by the shuttle car riers. all oit the shuttles beine` moved by mechanisms similar to that just described. This construction `is very compact and the arms Q7 and 2S on the carrier 1 5 are readily accessible owing to the 'fact that the' plate may be readily removed. The arms 9.7 and 2S on the carrier 18 are also readily accessible. lt will be seen that each arm is swung into and out ol. engagement with the shuttle by an independent cam track and that the cam tracks which control the actuating arms :tor any shuttle are so overlapped as to produce a compact arrangement.

By employing my invention it is possible to weave a larger number of ribbons for a given length of loom, or the same number of wider ribbons, than can be made on looms as heretofore constructed. It is also possible to apply the invention to existing looms without nniking extensive alterations therein overlapping cam tracks carried by said frame and each pair Cooperating with a pair 15 of said arms whereby said arms are alternately moved into and out of engagement with the shuttle'as the carriers are reciproeated, for the purpose described.

In testimony whereof I aix my signature 20 A in presence of two Witnesses.
