J. G. BENTLEY CLOTH INSPECTOR Oct. 10, 1933.
2 Sheets-Sheet 1 Filed June 1, 1931 (Wi i n" [I HI JOHN G. BEA/nay INVENTOR.
A TTORNEY.
Patented Got. 10, 1933 UNITED STATES CLOTH INSPECTOR John G. Bentley,
Greensboro, N. 0.
Application June 1, 1931. Serial No. 541,425
3 Claims.
This invention relates to an improved cloth inspecting machine in which means are provided whereby a greater portion of the cloth is exposed to view, at any one time, than other machines heretofore employed, and also a series of lightsare provided for illuminating portions of the cloth as it passes thru the machine, there being two sets of lights, one for illuminating the overhead traveling portion of the cloth, primarily,
and also assisting in the illumination of the vertically traveling section of cloth, and another series of lights are mounted on each side of the machine for illuminating particularly the vertical traveling portion of the cloth both sets of lights assisting in the illumination of the angularly disposed lower traveling portion of the cloth so that means are provided whereby the cloth can be inspected at three different points during its travel thru the machine and this inspection may be carried out simultaneously as all three portions are exposed to use.
Another object of this invention is to provide a cloth inspecting machine primarily adapted to receive a source of supply from a truck as shown in my co-pending patent application, Serial No. 510,048, filed on the 20th day of January, 1931.
Another object of thisinvention is to provide an inspecting machine having a suitable framework and in one portion of this framework a source of illumination is provided, preferably the source of supply upwardly behind and over the head of the operator of the machine, and forwardly over the head of the operator and then downwardly in front of the operator and then toward the operator before leaving the inspecting area of the machine, from whence the cloth is wound onto a suitable mechanism into rolls, bolts, or any other suitable packages. By this arrangement, it is possible, not only to inspect the cloth by looking upward overhead, but also by looking straight forward as it travels vertically downward, and also by looking downward as the cloth travels over a suitable board toward the operator, and on account of the peculiar arrangement of the various sources of light, it is possible to detect certain filling irregularities in one section of the machine, whereas the lights are so arranged as to particularly show up the irregularities in the warp threads of the fabric as it passes thru another portion of the machine.
The invention is so designed that the mercury lights will cause defects in the filling of the fabric, to be easily detected, whereas the filament bulbs mounted in the reflector housings on the sides of the machine are particularly adapted to show defects in the warp strands in the fabric. lhe combined effect of the three sources of light, that the mercury tube housing, and the various mercury tubes therein, and the two filament housings with the plurality of filament bulbs thereinare designed to give a general lighting effect to aid in the inspection process as well as to particularly point out the; defects both in the warp and the filling structureof the fabric as it passesthru the machine.
The mechanism is made more efiicient by a provision of a suitable alcove, partially housing the inspecting machinewhich provides a back ground of a suitable color to aid in the inspecting operation: and to assist the electric lights in the inspecting machine to cause the operator to easily detect the imperfections in the fabric. Due to the great area of the fabric exposed to inspection atall times, it is possible to run the inspecting machine at a verymuch higher rate of speed than has theretofore been accomplished in anycloth inspecting machine. 4
Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure l is a side elevation of the cloth inspecting machine; I
Figure 2 is a front elevation;
Figure 3 is a view of one of the housings for the filament bulbs, taken along the line 3+-3 in Figure 1.
Referring more particularly to the drawings, the numerals 10 and 11 indicate suitable uprights for the framework of the machine, said uprights 10 and 11 having bases 12 and 13 integral with the lower ends thereof Secured to the upper end of upright 10 is angular cross piece 14 and to the upper end of upright 11 is a similar angular cross piece 15 for supporting the upper structure of the machine. Projecting upwardly from one end of cross-piece 14 is a vertically disposed member 16 and likewise a similar member 17 projects upwardly from the corresponding end of crosspiece 15.
A suitable member 18 is secured between the ends of members 14 and 15, and likewise, the op posite ends of'members l4 and 15 have the secur-.
ing means such as rods 19 and 20 spaced apart from each other and secured to the cross-pieces 14 and 15, forming a space therebetween thru which the cloth may pass in the inspecting operation. The upper end of members 16 and 17 have rotatably secured therein the rollers 21 and 22 over which the cloth passes in the inspecting operation, and a suitable angular member 23 is secured between the uprights 16 and 17 for the purpose or" providing a rigid framework.
Mounted in close proximity to the uprights 16, and 17 and resting on the cross pieces 14 and 15, is a housing 25 in which the mercury tube lights 26 and 27 are mounted having the wires 28 and 29 leading to tube 27, and the wires 30 ano 31 leading to tube 26 from suitable sources of energy for conveying electrical energy to these mercury tubes for providing a source of illumination. This housing is open on the side most removed from the uprights 16 and 17 to cause the rays of light emitted by the tubes 26 and 27 to be thrown against the cloth 35 which is led from suitable roll 36 mounted in a truck 3'7, the structure of which truck is specifically disclosed and claimed in my co-pending application, Serial Number 510,048 filed on the 20th day of January, 1931.
Adjustably mounted on suitable screws 40 and 41 is a table 42 over which the cloth passes during the latter part of the inspection process, and secured to this 'tableare two supports 43 which have a roller or rod 44 mounted thereon in suitable upstanding bearing portions 45 so as to allow the cloth to pass beneath the roller 44 or rod 44 as the case may be after it travels downwardly from between the rods 19 and 20, and after traveling under rod or roller 44 passes across table 42 onto the takeup roll which will be presently described.
Mounted on the uprights 10 and 11 are the housings 47 and 48, both of these housings being identical and being secured to the uprights by means of lugs 49 and 50 projecting from the housing and being adjustably secured to brackets 51 and 52 secured on the uprights, and adjustable connections being maintained by means of bolts 54. A suitable source of energy 55 leading thru wires 56 and 57 provides electrical energy for the filament bulbs 58 mounted in each of the housings so as to project rays of light particularly against the vertical portion 60 of the cloth 35 in its downward travel.
At the front edge of the table 42 is provided a roller 61 over which the cloth passes, and
. mounted in suitable bearings 62 secured to uprights 10 and 11, is a roller 63 which has a yardage counter 64 associated with one end thereof, and the cloth, after passing over roller 63, passes onto a suitable tube 65, releasably mounted on a shaft 66 which shaft is releasably secured on a stud 6'? at one end thereof, and has a female portion into which the male portion 68 is adapted to fit at the other end thereof, and the cloth is wound in the form of a roll 70, on the tubular member -65, or if desired, othersuitable holding means may be employed for receiving the cloth and winding it in suitable packages.
The member 68 is suitably driven by means of a train of gears in a housing 72 which housing 72 -is conventional and the mechanism thereof is driven by a suitable source of power such as an electric motor '73 secured in any suitable manner to the mechanism contained within housing 72.
The starting and stopping of the mechanism is controlled by a treadle 74 on rod 75 having a crank '76 on one end thereof with a connecting rod '77 leading to the mechanism contained within the housing for starting and stopping the mechanism as desired by the operator.
It is seen that I have provided a cloth inspecting machine in which the web supply is located behind the operator and the cloth passes upwardly and over the operators head and then downwardly in front of the operator, and then angularly toward the operator and thus providing three different points at which the inspection process can be carried out in quick succession without the operator deeming it necessary to turn around, and if desired, a second operator could be positioned behind the web supply and carry out an inspection process on the cloth in its first upward travel into the inspecting machine.
By the provision of the alcove surrounding the machine which alcove has a top portion and sidewalls 81 and 82 and a back portion 83 painted or finished in any suitable color, it is seen that a suitable background could be provided excluding all outside light except that which enters through the front of the machine and the mercury lights being of such great intensity will prevent any cross lights from interfering with the rays of light generated by the sources of light in the machine, and it is thus evident that not only are the lights so arranged to give a general lighting effect, but also they are peculiarly adapted to cause one source of energy to bring out the defects in the warp of the fabric and another set of lights are adapted to bring out the defects in the filling of the fabric.
Furthermore, due to the great speed at which the mechanism is capable of being run, the machine is therefore, capable of performing a service equal to several machines and for this reason the device is very economical in that it dispenses with the services of several operators for inspecting a. given yardage of cloth within any given time.
In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms are employed they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
I claim 1. In a cloth inspecting machine, a pair of spaced uprights, a forwardly projecting member secured to the upper end of each of said uprights, an upwardly projecting member secured to the outer ends of said forwardly projecting members, a roller mounted in the upper ends of said upwardly projecting members, a rearwardly opening housing having its ends secured to the forwardly projecting members and having illuminating means therein, a pair of rearwardly projecting members secured to the upper ends of said uprights and having a roller mounted therein, an angularly adjustable table mounted between said uprights and having a roller mounted on its upper rear edge and having a roller mounted in its forward edge, a take-up mechanism mounted below said table, a rearwardly and inwardly opening housing secured on each of the uprights and having illuminating means therein, the cloth being adapted to be passed above the first and second mentioned rollers and below the roller on the rear edge of the table and over the roller on the front edge of the table and onto thetake-up mechanism, whereby an operator standing in front of the table may inspect the cloth overhead, in front and below the eyes of the operator.
