NIKOLAUS THOLL, OF HOOSICK FALLS, NEW YORK.
THROAT FOR BRUSH-MAKING MACHINES.
Specification of Letters Patent.
Patented Aug. 27, 1918.
Application filed May 9, 1918. Serial No. 233,547.
To all whom it may concern:
Be it known that I, NIKOLAUS TrIoLL, a citizen of the United States, residing at Hoosick Falls, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Throats for Brush-Making Machines, of which the fol lowing is a specification.
Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.
This invention relates to a brush-making machine in the use of which small bunches of bristles or the like are doubled and driven, in connection with a wire staple, into a closefitting aperture in the brush-back or block. In such machines the bristles are embraced midway of their length by the staple and the staple and bristles are then together forced through a converging throat, causing the bristles to be doubled and to leave the contracted end of the throat in compact form.
The interior of such a bristle-feeding throat must be quite accurately formed; and in machines adapted for making the smaller brushes such as hair-brushes, the throat is of such small dimensions that it is found eX- tremely difficult to properly machine the interior of the throat so that the same shall be of accurate dimensions and shall be provided with the necessary grooves for guiding the bristles and the staple.
On account of this difiiculty it has been customary to make such a throat of comparativelv soft easilv workable metal, as a result of which the throat quickly becomes so worn that the form and size of the passage; way therethrough are materially changed and rendered inaccurate, and the stapleguiding grooves become enlarged by wear and fail to properly guide the staples.
The principal objects of'the present invention are to secure greater accuracy, and longer period of usefulness of such a throat and to facilitate the manufacture and repair of such throats.
Other objects will appear in connection with the following description.
Figure 1 of the drawings is a view in front elevation of a throat made in accordance with my invention.
Fig. 2 is a similar view of the two parts of the divided block slightly separated from each other with the face-plates removed.
Fig. 3 is a view in elevation of the inner side of one of the block-members.
Fig. 4 is a view in elevation of one of the face-plates.
Fig. 5 is a horizontal cross section of the throat taken on the broken line 5-5 in Fig. 1.
Referring to the drawings wherein the invention is shown in preferred form, the throat comprises a block divided on a plane extending from front to rear, into two parts or members, 1, 2, which members are later ally separable from each other as shown in Fig. 2.
The block-members, 1 and 2, are provided on their inner sides with complementary channels, 3, together forming a bristle-passageway down through the throat.
One of the block-members, as 1, is provided with dowel-pins, 4, which fit the respective oppositely disposed apertures, 6, in the complementary block-member, 2.
The block-members are detachably secured together by means of a screw, 7 extending through an aperture, 8, in the block-member, 2, into a similarly screw-threaded aperture, 9, in the block-member, 1, as shown in Fig. 5.
WVithin the block thus formed, I mount upon opposite sides of the bristle-passageway a pair of face-plates, 10, reducing the bristle-passageway through the throat to the proper width.
These face-plates, 10, extend across the line of division between the bloclemembers, 1 and 2, and each face-plate is secured in position by four screws, 11, inserted from the outer side of the block into each of said face-plates, two of said screws extending through the block-member, 1, and two through the block-member, 2, on each side of the block.
The block-members are thus connected together by the face-plates, 10, as well as by the screw, 7, and the dowel-pins, 4, so that the whole throat-structure is rigid in use.
Each face-plate, 10, is provided with a longitudinal groove, 12, said grooves being located opposite each other and forming a guide for the staples, not shown.
The block-members, 1 and 2, are provided at the contracted end of the throat with bristle-guiding grooves, 13.
By the use of the divided block and face plates, the manufacture of the throat is greatly simplified, and all of the surfaces which require accurate machining are readily accessible for the machining operation.
By employing the face-plates, 10, in combination with the divided block, I not only strengthen the connection between the blockmembers, but make it possible to greatly prolong the life of the throat by renewal of the face-plates, 10, from time to time as they become worn.
If desired, the face-plates, 10, may be made of hardened steel.
iVhat I claim as new and desire to secure by Letters Patent isl. A bristle-feeding threat for brush-male ing machines comprising a block divided into two members on a plane extending from front to rear, said members being provided with complementary channels forming a bristle-passageway through the block; a pair of face-plates detachably mounted within said block on opposite sides of said passageway extending across the line of division of the block; and detachable means for securing each block-members.
2. A bristle feeding throat for a brushfeeding machine comprising a block divided into two members on a plane extending from front to rear said members being provided with complementary channels forming a tapered bristle passageway through the block, said channel walls being formed with oppositely disposed bristle-guiding grooves in the smaller end of said passageway, a pair of face-plates detachably mounted within said block on opposite sides of said passageway extending across the line of division of the block, said face-plates being provided with oppositely disposed staple-guiding grooves; detachable means for securing said block-members directly together; and detachable means for securing each of said faceplates to both block-members.
In testimony whereof, I have hereunto set my hand this 4th day of May, 1918.
NIKOLAUS THOLL.
of said face-plates to both Copies of this patent be obtained for five cents each, by addressing the Commissioner of Patents, Waahingtcn, 83
