Y., a corporation of New York Application October 10, 1940, Serial No. 360,607
7 Claims. ((31. 91-12) n manufacture of caps on telephone transmitters and receivers and adds to the appearance of the articles. However, when the molding fin is removed in this manner, the color and finish of the surface of the article in the groove is difierent from the remainder of the article. This difference detracts from the appearance of the articles and it is, therefore, desirable to color the grooves to the approximate coloring on the molded surfaces. The use of air brushes and stationary wicks or wipers has proven uneconomical since, with the particular type of coating used and the portion of the article to be coated, it is diflicult to prevent the applicators from drying or clogging and thereby applying an uneven flow of stain to the portion of the article to be stained.
An object of the present invention is to provide a simple apparatus for quickly applying coloring composition to portions of articles.
In accordance with one embodiment, the present invention is designed particularly to provide means for economically applying stain to a groove formed in telephone handset transmitter and receiver caps. This is accomplished by drawing twine from a cop, through tanks containing stain, and directing it into the grooves in two transmitter or receiver caps while the caps are being rotated on a grooving machine turntable, which is operative to cut grooves in two caps at one time and then index two positions to carry two new caps into association with the grooving apparatus. A cam formed on the turntable controls part of the guiding mechanism for the stain applying twine and moves that portion of the guiding mechanism into position where the twine, guided thereby, will engage in the grooves in the caps during their rotation. The cam is effective to move the guiding means out of the path of the caps being stained upon indexing motion of the turntable which supports them.
A better understanding of the invention will be had by reference to the following detailed description when considered in conjunction .with the accompanying drawing, wherein Fig. l is a plan view of a portion of a milling or grinding machine for rotating transmitter or receiver caps to remove the molding flash from them, to which machine there has been attached mechanism embodying a preferred form of the present invention;
Fig. 2 is a side elevational view of the preferred form of means for applying stain to the grooves in receiver and transmitter caps, and
Fig. 3 is a vertical sectional view taken along line 3-3 of Fig. 1 in the direction of the arrows showing details of the mechanism for shifting the movable guides,
Referring to the drawing, wherein like reference characters designate the same parts throughout the several views, a turntable 5 is shown for carrying receiver caps 6 past a milling station (not shown) and into a staining station, as shown in the drawing. The turntable 5 is indexed by mechanism (not shown) to carry two receiver caps 6 into engagement with two grooving mechanisms (not shown), where the parts are rotated while the groove is formed in them by a grooving tool. Driving mechanism mounted within a housing I2 is provided for rotating the receiver cap 6 held on the turntable 5 between a clamping idler 9 and a cap driving member II. Each of the receiver caps 6 has a groove 3 formed in it by a suitable grinding or milling operation in a portion of the machine (not shown), and it is this groove that the present apparatus is designed to stain.
The circular housing I 2 has fixed to it a bracket I3, which supports the stain applying apparatus. Mounted on the undersurface of the bracket I3 is an arm i l, on which there is rotatably supported a cop iii of ordinary cotton twine. In preparing the apparatus for operation, the twine it is led from the cop l5 through a slot l6 formed in the bracket l3 and through a spring brake ll composed of a relatively stiff plate l8 and a spring l9, which is attached to the plate It by a bolt and thumb nut assembly 20, whereby the pressure of the spring 5 9 on the twine Ill may be adjusted to place a drag on the twine It. A container 21, in which there may be placed a suitable supply of staining composition, is mounted on the bracket [3 and has an aperture 28 formed in its front side. Within the container 21, there are suitably positioned three guide rollers 29, 39 and 3|, which direct the twine l0 through the staining composition in the container 2?. The twine is directed upwardly from the guide roller 3! through an aperture 32 formed in the top 26 of the container 27 to a guide roller 33 mounted on a bracket 34, which is, in turn, fixed to the top 25 of the container 21. The twine I is then directed to a guide roller 35, rotatable on an arm 25, mounted on the bracket I3, and thence to a guide member 36.
The guide member 36 and a second guide member 31 are formed on the upper surface of a plunger 38 slidable between a block 39, fixed to the bracket l3, and a plate 43. The plunger 38 has a pocket 4| formed in it to receive one end of a coiled spring 42, which urges the plunger toward the axis of the turntable 5, being interposed between the end of the pocket 41 and a plate 43. A block 45, fixed to the bracket 13, supports the plate 43 and is mounted below a notch 41 cut in the bracket l3 to permit movement of the plunger 38 almost into engagement with the plate 43.
Extending downwardly from the plunger 38 is a post 49, on which is rotatably mounted a cam roller designed to ride on a cam 53 mounted on and coaxial with the turntable 5. The cam 53 is so formed that the cam roller 51 will move radially toward the center of the turntable 5, between alternate caps 5, upon rotation of said turntable.
When the plunger 38 moves to the position shown, the twine IE] will be stretched and will be held between the guide roller and guide member 36 in position to enter the groove 8 in one of the caps 6 while the cap is being rotated by its driving member II. From the guide member 33, the twine I0 is directed to a guide roller 80 supported on a bracket 5|, which is, in turn, mounted on the top of a second container 62. The guide roller serves to direct the twine l5 downwardly through an aperture 63 in the top of the container 62 to guide rollers 34 and suitably supported in the container 82 below the level of the coating or staining composition. Also mounted upon the bracket BI is a second guide roller 65, which directs the twine ID to the guide member 31 and thence around a guide roller 52 and a guide roller 54 to a knurled driving member 55, which cooperates with a knurled idler 56 that is suitably pressed against the driving member 55. Power is supplied to the driving member 55 through a speed reducer 51 from a driving motor 58 to draw the twine In over the various rollers and guides through the two containers 21 and 62 and direct the twine Iii into a suitable receptacle 59, from which it may be periodically removed and discarded.
It should be noted that the guide rollers 35 and 52 and the guide members 36 and 31 are so positioned that the twine in the area between them will bear tightly in the grooves 8 in the caps 6 at two positions, when the plunger 38 is in the forward position, as shown, thereby to apply stain from the containers to the grooves in the caps during the rotation of the caps by the driving members ll. When the turntable 5 is indexed about its axis, the cam roller 5! will move the plunger 38 outwardly to carry the plunger and guide members 36 and 31 out of the path of the caps 6, and when the turntable has moved two positions, the cam roller 5!, following the contour of cam 53, will return the guide members 36 and 3'! to the position shown.
