MEANS FOR MAMUFACTURING COMBS FOR GOMBER MACHINES Filed May 25, 1945 5 Sheets-Sheet 3 Patented July 27, 1948 UNITED STATES PATENT OF MEANS FOR MANUFACTURING COMBS FOR COMBER MACHINES Joseph P. Curry, New Bedford, Mass.

Application May 23, 1945, Serial No. 595,405

The present invention relates to a novel and improved means for expeditiously and economically manufacturing so-called half-laps or special metal combs for complemental use in parallelism in comber machines such as are employed in the textile industry to comb and straighten various kinds of fibers.

Secondly, the invention has to do with a special steel needle assembling, aligning, spacing and clamping vise, whereby to permit said needles to be adequately and satisfactorily soldered to the back or body of said comb in a manner to function as teeth.

In carrying out the principles of the invention, I utilize a reciprocatory shaking table, this have ing an inclined needle assembling and drifting trough at the needle discharge end, the needles being delivered by forces of gravity and agitation into pockets provided therefor in a special twin-block vise, the blocks being so constructed so as to expeditiously locate, uniformly space,

and orderly clamp and position the needles so.

that protruding shank portions thereof may be secured to the back of the comb and the comb quickly made up and finished for use.

Other features and advantages will become more readily apparent from the following description and. the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is a face elevational view of the aforementioned twin-block needle assembling and retaining vise constructed in accordancewith the adopted principles of the present invention.

Figure 2 is a side elevational view of the same, that is, a view observing either one side or one face, this View showing a plurality of the needles clamped in position for subsequent attachment to the comb body. I

Figure 3 is a transverse or cross-sectional view, this taken on the plane of the line 3-4 of Figure 2, looking in the direction of the arrows.

Figure 4 is an inside face and elevational view of one of the blocks or sections of the vise, this view being taken approximately on the plane of the longitudinal line 44 of Figure 1, looking in the direction of the arrows.

Figure 5 is a similar view of the companion block or section, this taken on the plane of the line 5-5 of Figure 1, also looking in the direction of the arrows. V

Figure 6 is a fragmentary perspective view 2 Claims. (01. 140-100) with the blocks separated to show the construetion of the meeting surfaces or faces thereof.

. Figure 7 is an end elevation of Figures 1 and 2, observing. same in a direction from right to left and showing the steps whereby the shank portions of the needles are soldered to the body so as to complete the comb, said needles serv ing as teeth. Figure 8 is a top plan view of a fragmentary type showing the reciprocatory shaking table,

the trough and the associated needle assembling and retaining vise.

Figure 9 is a perspective view of the same.

Referring now to Figures 1 to 7. of thedrawings bydistinguishing reference numerals, it will:

be observed that the special needle grouping, as-

sembling, spacing and clamping vise is denoted," as a unitary structure, by the numeral l0. 'It

comprises a pair of complemental or companion blocks or sections H and I2. These are of gen-, eral rectangular form and of approximately equal dimensions and shapes exteriorly visualized. Also, the blocks are preferably hollow to cutl down weight. The internal partitions make said blocks of cellular form, this being the, preferred mode of construction. The inner surfaces 13 and M are fiat and are adapted to be brought; into firm mating relationship (see Figs. 3 and 7). The surface [3 in the block J2 (Figs. 5 and 6) is provided with a longitudinal groovel5 form ing a keyway, and this opens through opposite transverse ends of said block. The narrow longitudinal area or region It is perfectly flat and plain and constitutes a straight edge. The surfaceof the face l4 opposed to the straight edge It, that is, in the block II, is provided with a multiplicity of uniform and properly spaced V-shaped notches I! which constitute the as sembling, spacing and subsequent clamping pockets for the shank ends of the needles l 8.. In addition, a horizontal or longitudinal strip is inserted into a groove formed in the block H;

gether and maintained in clamping relationship by bolts 20, latter clamped in place retaining nuts 2|.

I next call attention to the aforementioned agitating and shaking table, (see Figs. 8 and 9), this denoted generally by the numeral 22. The

table includes reciprocatory, spaced parallelside rails 23 mounted on an operating machine (not needles i6 011 the surface 2!! all have a tendency points first.

not shown, and then the step shown in Figure 7 is pursued. That is to say, the back or body ofthe comb 26 is put in position and the shank ends of the needles are soldered, welded or otherwise connected to. said part 26 and the comb is. finished.

]'l. hefinished comb, an allqnetal unit, is often referred to in the cotton textile trade as a halflap, and is used in a machine called a camber, which combs and straightens textile fibers. The expression,halflap is also used to designate a series of combs, parallel to one another, fixed to a; curved surface forming a part of the. comber machine.v

Thee, are three. highly important features in onnection withgthe vise and vise block which appearv to be'original and which. have resulted in an; appreciable saving of time, labor and materials. These, features are as follows:

No. 1. 'I hel permanent or built-in strip H1 in theblock l I with'a longitudinal edge portion pro- J'ecting serving 'as a leveling-up, straightaQifOSS ledge is distinctive and highly important. On. other blocks or clamps used inthe trade, the stright-edge is. subject to employment. in conjunction therewith of numerous ffgadgets for setting and. adjusting purposes. This painSt2tk-- ing; and, time-consuming method'is modifiedand improved through the use of. procedure and the, ledge-equipped" blockin the vise is highly important, obviously. There, is noloss of'time in ad usting or setting. When the needles drop into the pockets, the pointed ends rest on the flat surface. of the; ledgev and are. thus placed. nicely in positionfor clampingand subsequent attachment purposes. The V shaped notches. acting in con.- junction withthe strip serve and provide for thisreceiving and-assembling step and. are also worthy of consideration.

In other devices, known. to me and used in thetrade, along,- n'arrow, rectangular strip. of wood isoften used instead of the permanent metal straightedge "16.. These strips of wood are used in lar e numbers over the course. of a. year or so, and a, great, deal: of patience and time is. required to settthemin. the clamps for-user Al1 thisis eliminated in theinvention. and method herein; covered.

3M1 3.-. A lthough. it isL of incidental consideration and importance, it. is felt that the idea of employing the, hollow blocks constructed along the..lines shown and boltin these together is of. outstanding importance. That is, considering 4 the possibility of quickly separating and then firmly abutting the blocks by simple bolts and nuts is a contributing factor to gettin all of the needles quickly assembled and lined up right for subsequent attachment, anchorage and comb making purposes.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings willenable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

I claim: 1
