Specification of Letters Patent.
Patented Oct. 9, 1917.
Application filed November 22, 1916. Serial No. 132,762.
To all whom it may concern:
Be it known that I, MANDEL BLoox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Thread Outtmg Dies, of which the following is a specification.
My invention relates to thread cutting dies such as are used by plumbers, ters and others to cut threads upon pipes or rods. The object of the invention is to pro vide means for keeping the work clean during the process of cutting and to thereby enablethe die to produce a more perfect piece of work. I accomplish this briefly by furnishing the die with one or more brushes of proper type of a length preferably equal to the thickness of the die, said brush traveling in front of the chaser or cutting element and thereby keeping all of the threads and the surface of the work clean. The, principle of the invention is illustrated in the accompanying drawings, in which Figure 1 is a face view of a die provided with my invention. Fig. 2 is a sectlonal view on line 22 of Fig; 1. Fig. 3 is a sectional view on the line 3-3 of Fig. 1. Fig. 4: is a perspective view of a die furnished with a brush of somewhat modified construction.
Similar numerals refer to similar parts throughout the views.
The body of the die is of the ordinary type used in die stocks and it is furnished with a plurality of chasers or thread cutting elements 2, of any suitable construction. Ordinarily the chasers will extend from one face of the die body to the other but the cutting threads will not extend quite the entire length of the chaser, for reasons understood by those familiar with this art.
In the form shown in Figs. 1, 2 and 3 the brushes consist of wire bristles 3, ex-
tending from a base 4, the base being so rabbeted into the inside of the die body po sition that when the die is taking a cut the brush will be in advance of the chaser. The number of brushes may be varied, Fig. 1 showing a die with four chasers and two brushes and Fig. 4 showing one with four steam fitspread, as they will be when in tinuous row in which the bristles touch each In the form illustrated in other but they do extend over a considerable part of the thickness of the die and when action, the acting portions of the bristles come fairly closely together, at least for that portion of the work where the cut is actually being taken.
In operation the die is started upon the work, as suggestedyin Fig. 2, and is then rotated by a hand stock or otherwise. The
brushes traveling in front of the chasers I will continually brush the chips or cuttings from the surface of the work and thereby enable the chasers to take a clean and perfect out. It will'be understood by those familiar with thread cutting that it is the custom to pour oil or thick soapy water upon the surface of the work during the cutting operation to facilitate the cutting process. This oil or other lubricant, while it assists in the cutting operation, tends to make the chips stick to the work and these frequently get "between the chaser and the work and cause the production of imperfect threads. These chips are, of course, being formed at all points where the chasers are cutting into the work, but with this device the brushes cover all, or a large part of the surface of the work which is actually being cut and thereby keeps the surface clean and smooth. The brushes in the preferred designare arranged practically radially, with the result that as they are resilient they operate to flick the cuttings forcibly from the surface of the work. My device, therefore, is very effective in its action and produces a clean perfect cut, with no addimidway between two ohasers, the axial length of the brush being approximately as 0 great as the axial length of the chaser, the brushes having resilient bristles for contacting and sweeping the surface of the work;
In witness whereof, I have hereunto subscribed my name.
