' The invention relatesto b'unch building on bobbins, as described in the present specification and illustrated in the accompanying drawings that form part of the same. The inventioniconsists essentially of the novel'features of construction pointed out broadly and'*specifically' in the claims for novelty following'a description containing an explanation indetail' of an acceptable form of the invention. j l
' The objects of the'i'nv'ention'are to build *upa small bunch of yarn at the'base of the bobbin for the purpose "of maintaining the operates the mechanism forjdischarging the empty bobbin to be replaced by a full bobbin from the battery or magazine and to do this by means of a cam mechanism forming an addition to the cam mechanism for operating thering rail of a ring spinning machine; "to eflect this precaution against misspiclrs without aifecting the'efliciency of such machines or adding c0mplications,'that will materially increase the cost of production and maintenance; and generally to provide amech'anism for'the purposes aforesaid of a simple and durable character and readily 'adaptableto modern machinery. I v *In' the drawings, Figure 1 is an elevational View of a section of a ring frame machine showing the tilting ring frame, operating lever and the centre of the bevel driving gear broken away 'to disclose the mechanism of this invention. 7
Figure 2 is an end elevational View of the driving gear and cam mounting and clutch member. r i Figure 3 is an enlarged elevational detail 4 of the cam mechanism showing a fragmenetary View of the lever in engagement with the bunch builder cam.
Figure 4 is an enlarged detail of the cam 7 showing it in clutchfor bobbin winding purmounting and clutchv .member.

Figure 8 is a detail of the bunch builder cam plate. I I
Figure 9 is an enlarged detail of a shuttle '55 containing the bobbin.
Figure 10 is a detail of a bobbin showing the feeler slot.
Figure 11 is a detail of the feeler.
Figure12is a vertical sectional view cor- 6O responding to Figure 2 and showing the cam shaft in longitudinal section and the'external cam in vertical section.
Like numerals of reference indicate corresponding parts in the Various figures.
Referring to the drawings,the heart shaped cam, indicated by the numeral 15 may be herein termed theexternal cam, which controls the traverse of the ring frame operating lever 16 which is pivoted at 17 and osci1- lates" in conformance with the rotation of said cam to accomplish its purpose, which contributes to the winding of the bobbin 18, and while certain parts are illustrated in connection with the windingof this bobbin, they all form part of the mechanism which is already in extensive use and may be called conventional or familiar in the trade. There fore in this invention by an initial revolution of the cam shaft without rotating the 30 cam 15 a reserve bunch of yarn is built up at the base of the bobbin prior to the actual winding thereof.
The external cam 15 is rigid with the hub 19 and is to receive the shaft head 29 and at 21 to receive the dog 35, the slot 23 extending inwardly through the rim of the cam and forming a receptacle for the loose cam plate 24, said cam plate 24 having the slots 25 and 26 through which the pins 27 and 28 extend in order to loosely-hold the cam plate 24 to the cam 15, that is to say, when the cam 15 is rotating and causing the traverse of the ring frame lever, the cam plate 24 maintains its inner position.
3. In bunch building on bobbins and operating mechanism, a pivoted lever, a cam shaft suitably journalled and driven, an internal cam and clutch member in fixed relations to said shaft, an intermediate cam plate forming the operating connection from said cam to said lever, an external cam carrying said cam plate and loosely mounted on said cam shaft, and a clutch member pivotally mounted on said external cam and springheld to the aforesaid clutch member.
4. In bunch building on bobbins and operating mechanism, a pivoted lever, a cam shaft suitably journalled and driven, an internal cam and a clutch member in fixed relations to said shaft, an external cam loosely mounted on said cam shaft and recessed and slotted, a push plate slidably mounted in the slotted external cam and forming a reach member from said internal cam to impart motion to said lever, a clutch member pivotally mounted on said external cam and engaging the aforesaid clutch member following the operating engagement of said push plate with said lever and bringing the external cam into operating engagement with said lever.
Signed at Montreal, Canada, this 16th day of February, 1929.
