THREAD CUTTER Filed April 27, 1929 3 Sheets-Sheet 3 Patented Apr. l, 1930 UNiTED sTATEs PATENT OFFICE THEODORE F. NAUMANN, OLT' DAWTUCKET, RHODE ISLAND, ASSIGNOR TO SEEKONK LACE COMPANY, A CORPORATION OF RHODE ISLAND THREAD CUTTER Application led April 27,
tate the propulsion andreciprocation of the machine; to provide means for elevating the blades and for maintaining the same in elevated position while the machine is inactive; and to attain the above ends in a structure of an extreme compactness and portability,
facile to operate, and simple and inexpensive to construct.
To the above ends, essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.
In the accompanying drawings which form a part of this specification,
Figure 1 is a top plan view of my thread cutting machine showing parts thereof brok-en away in various planes,
Figure 2, a partial section of the same on line 2-2 of Figure 1,
Figure 3, a side elevation of the same, partially fragmentary,
Figure 4, a fragmentary `section on line 44 of Figure 2,
Figure 5, a perspective view of one of the blades and its guard attachedto the end of a supporting arm,
Figure 6, a detailed viewA of one of the blades disassembled, and
Figures 7, 8 and 9, side elevations of the parts shown in Figure 5 indicating the positions shown assumed by the guard during the various stages of the thread cutting operation.
Like reference characters indicate' `like parts throughout the views.
The framework of my device includes substantially oblong side walls or plates 12 connected at their upper corners by cross bars 14; and at points below the latter, by cross bars 15. Journaled upon laterally projecting studs 19 in the .lower earners of 'the-side 192e. serial No. 358,655.
plates are wheels or rollers 20 extending slightly below the lower edges of the plates. The described frame is longitudinally reciprocated, in this instance manually, by a detachable handle pivotally engaging one or the other of the cross bars 14. The handle comprises a shaft 22, a handlebar 23 near vits outer end, and a fork comprising diverging flat metal arms 24 fixed to the inner end of the shaft and provided with open upwardly directed slots 26 near their inner-extremities to loosely receive the cross bar.
Pivoted to each of the rods 15 is a brush frame comprising two interspaced Vflat metallic arms 28. The pivoted end of each arm is formed by an open loop BO'closed by abolt 32 connecting the free end 34 of the loop with the rod through perforations not shown. The arms have downwardly bent end portions fixed by screws 36 to the outer face of a cross piece or brush back 37 in which are fixed downwardly directed tufts of bristles 38. The arms 28 are detachable, in cases where a brush is not required, by removing the bolts 82.
A pivot shaft 40 has its ends fixed in the side walls-12, midway their ends in a plane below the cross bars 15. It is provided at its ends ad'acent the walls with spacing collars 43 at oth sides of two oppo'sitely disposed series of depending downwardly inclined blade carrying arms 48 and 49 respectively, loosely pivoted upon thel shaft. The individual arms of one series alternatewith the individual arms ofthe other series, and the arms-of both series are alike in `detailed construction.
In detail each of arms 48 and-49 comprises an innersection 5() and outer section 5-1. At the inner end of each arm section 50 isan opening 53 through which loosely passes the shaft 40. Surrounding the opening, in Vthis instance, are spacing hubs 54 upon both sides of the section. Continuous withthe inner ends of the arm sections 50 are longitudinally directed extensions or lingers 56. The outer end of the section 50 -iscurved and, as shown in Figure 4, is provided `with a lateral circular recessed or countersunk 'pertion 58. The inner and 01E-enchanter man section 61 is also curved and provided with a lateral circularly recessed or countersunlr portion 60 abutting against the portion 58 of the arm section 50. The arm portions 58 and 60 are each provided with a central threaded perforation 62 registering with each other through which passes the threaded shank 6-1 of a clamping screw 65 having a head 66. By means of this screw the arm sections 50 and 51 may be angularly adjusted relatively to each other.
Carried by thn outer en-d of each arm 51 is a flat substantially acute angular blade 68 having a horizontally disposed blunt bearing edge 69 upon the lower margin with a slight upward bevel or inclination 70 at its free end or point. The upper margin of the blade has a cutting edge 71 upwardly inclined from the blade point to a notched portion 72, near its inner end, also provided with a cutting edge 78, and a shoulder portion 74 adjacent the notched portion provided with a vertical cutting edge 75 continuous with the other cutting edges. The blade has an upwardly inclined attaching lug 76 at its inner endV provided with an opening 77, and iits in an inclined lateral recess 7 8 in the outer end of the arm section 51, and is retained therein by a 'clamping screw 7 9 passing through the opening r r.
Cooperating with each blade is a forwardly directed resilient presser arm represented in a general way by the reference numeral 80 formed from a thin strip of resilient material. The inner end 81 of the strip constitutes an attaching portion resting upon the upper edge of the arm section 51, near its free end, and is fixed thereto by a screw 82 passing through a perforation, not shown. The remainder of the strip forms a horizontally disposed substantially elliptical arm comprising an arched upper portion 84, a curved end portion 85, and an arcuate lower portion 86 whose detached free end 87 is upwardly inclined and terminates adjacent the arm section 51. A central longitudinal slot 89 in the portions 85, 86 and 87 of the presser arm receives the cutting portion of the blade, so that the bifurcated portions of the presser arm slidably embrace the sides of the blade at points even below the cutting edge of the latter.
The blade carrying arms 48 and 49 are individually supported at their outer ends by the bearing edges 69 of the blades which slide, under the influence of gravity, in contact with the fabric 90 to be treated, which is clamped in any convenient manner to a floor, table, platform, or the like 91.
Means for maintaining the blades in elevated or inoperative position when the machine is not in operation consists of two similar oblong cooperating plates 93, extending across the machine transversely diverging from each other in a downward direction.
Each plate has inwardly directed rectangularly disposed attaching lugs upon its ends adjacent its upper lateral edge provided with holes 97 through which the shaft L10 loosely passes. In this case the plates are assisted in maintaining a normally transversely inclined or distended position by retractil@ springs 98 attached at their inner ends, as at 99, to portions oil' the plates adjacent their lower lateral edges, and attached at their opposite ends to the rods 14s. This form of spring means is not exclusive, and may be entirely dispensed with if desired. When the tensioning means are employed stop pins 100 in the end walls projecting into contact with the plates may be used. rfhe plates are compressible to parallel vertical positions, as shown in Figure 3, by a rigid clamping yoke 102 whose legs 103, as the yoke is depressed over the plates, cause the lower lateral edges of the latter to move in an are against the free end portions 5G of the arms 18 and 49 which tilt the latter and elevate the blades G8 into inoperative position.
To utilize the machine the operator applies the handle to either of the rods 14 and pushes or reciprocates the machine in any preferred direction over the fabric 90 supported with its superliuous threads exposed. The positions of the machine parts during operation 9 are as shown in Figures 1 and 2. The blades G8 slide upon their bearing edges 69 over the fabric 90 operating to sever the loops, binding threads, bridge threads, or floating threads previously elevated more or less by the brush elements 38 positioned in advance oi the blades. The cutting action of a blade upon a typical thread 104 is graphically shown in the last three figures of the drawinvs.
In Figure 7 the thread loop 104 has reached in its travel the presser arm portion 85 without severance, although often the severance has already occurred. In Figure 8 the unusually tough thread 104 has reached a point where it is increasingly pressed against the blade edge 71 by the presser arm portion 8G which has been forced upwardly by the thread. This pressure would naturally sever any thread. Assuming the latter to survive, however, it reaches finally the position shown in Figure 9 against the vertical cutting edge 75, where severance is invariable, and prevents tearing of the textile fabric 90 which otherwise would result.
