- FALLER BAR FOR FIBRE PREPARATION MACHINE Filed May 31, 1966 .BY 7927M, M/a fimwu United States Patent 0 3,398,437 FALLER BAR FOR FIBRE PREPARATION MACHINE William Rennie Stewart, Strathmartine, by Dundee, and David Bruce Stewart, Newtyle, Scotland, assiguors to Wm. R. Stewart & Sons (Hackelmakers) Limited, Dundee, Scotland, a corporation of the United Kingdom Filed May 31, 1966, Ser. No. 554,157 Claims priority, application Great Britain, May 31, 1965, 23,070/ 65 3 Claims. (Cl.
- ABSTRACT OF THE DISCLOSURE A taller bar having pin holes of a length less than the depth of the taller bar extending from the upper surface of the bar and terminating in a longitudinal recess within the bar short of the underside thereof, and pins mounted in said holes and having shank end portions exposed by extending into the longitudinal recess.
- Each pin hole has a lower counterbore portion which registers with the longitudinal recess in the underside of the taller bar.
- This invention relates to fibre preparation machines by which the fibres are subjected to a combing action preparatory to spinning.
- taller bars which consist of steel bars and having upright pins that comb the sliver of fibre undergoing treatment in a taller gill machine, the taller bars at the end of their traverse falling down preparatory to starting a new traverse.
- the depth of the pin holes in a taller bar is less than the normal thickness of the bar, each hole merging with an enlarged bore or a longitudinal cut-away section or slot or recess in the bar so that part of the shank of the pin is exposed, or combination of the above.
- FIGURE 1 is an elevation, partly in section, of a taller bar in accordance with a preferred embodiment of the invention
- FIGURE 2 is a section on the line IIH of FIGURE 1,
- FIGURE 3 is an elevation
- FIGURE 4 is a transfer section, on the line IVIV ot FIGURE 3, of an alternative design of taller bar.
- B indicates the taller bar in which are pin holes to receive the pins P for combing the fibres undergoing treatment.
- the problem of repairing or replacing a damaged or worn pin is overcome by providing in the bar a pin hole 1 the depth of which is less than the normal thickness of the bar, the hole 1 merging with a counterbore 2 0t enlarged diameter through which the shank 3 of the pin projects.
- the counterbore 2 the operation of removing a damaged pin is facilitated since it is possible by means of a suitable punch tool to have access to the pin in order to dislodge the pin from the hole 1.
- the shank 3 has a cross-section less than that of the cylindrical portion or stem of the pin so that on removal of a pin it is sufiicient to advance the pin by a limited amount, i.e., until the stem is clear of the hole.
- a counterbore it enables a relatively large sized punch to be used on the end of the shank and the punch will not become burred.
- the counterbores 2 merge with a longitudinally extending slot 4 formed on the underside of the bar which provides further clearance and enables a number of pins to be removed at once by using a punch with an elongated rectangular head.
- the pin holes extend from the upper side to the underside of the taller bar B, each hole comprising an upper portion, such as a bore of relatively small cross-sectional size extending from the bar upper side toward the underside thereof but terminating within the bar short of the underside, and a lower portion such as a counterbore ot enlarged cross-sectional size extending downwardly from the lower terminus of the upper portion.
- Each pin P comprises a tapered upper or front portion, a central portion of uniform cross-section, and a rear or lower portion of reduced cross-section.
- FIGURES 3 and 4 there is shown a bar having two rows of holes 5 and 5 and corresponding countersunk holes 6. Instead of slotting the rear face of the bar the metal is cut away so as to leave a central web 7 providing edge recesses or slots giving tree access to the shanks 3 of the respective rows of pins as clearly shown in FIGURE 4.
- the taller or stave bar of this invention is more especially intended for use with pins comprising a cylindrical middle portion which is a friction fit within the hole in the bar and having a pointed front portion and a rear portion which becomes thinner towards its rear end which is blunt.
- pins comprising a cylindrical middle portion which is a friction fit within the hole in the bar and having a pointed front portion and a rear portion which becomes thinner towards its rear end which is blunt.
- One form of such pin is the subject of our prior Patent No. 3,123,866.
- a taller bar having pin holes of length less than the depth of the taller bar, said pin holes being counterbored and said taller bar having a longitudinal recess in its rear face registering with the counterbores; and pins mounted in said holes and having shank ends extending into said counterbores and recess.
- a taller bar having two rows of pin holes extending from the upper side to the underside of the bar, said holes respectively comprising an upper bore portion of relatively small cross-sectional size extending from the bar upper side toward the underside thereof but terminating within the bar short of said underside and a lower counterbore portion of enlarged cross-sectional size extending downwardly from the lower terminus of said upper portion, the underside of said bar having edge recesses into which the respective rows of hole counterbore portions extend; and pins respectively mounted in said hole upper bore portions and extending into said lower counterbore portions.
