D. FRANK'HARTFORD, OF BOSTON, MASSACHUSETTS.4 Leners Patent No. 72,632, and Dagmar 24, 1867.5
IMPROVEMENT-IN STRINGING BOW- DRILL STOCKS.
TO ALL WHOM IT MAY OONCERN:
Be it known that I, D. FRANK HARTFORD,`0` Boston, in theA county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in the Method of Stringing Bow-Drill Stocks; and I do hereby declare that the following is a full and exact description thereof, reference being had tothe accompanying drawings, and tbeletters of' reference marked thereon. y
l The nature of my invention consiste in a. peculiar method of Stringing a bow-drill stock, and applies particularly to the bow-drill stock ,patented by ine, August 27, 1867, Patent'NiL 68,071.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construetion and use, In thedrawings- Figure is a. perspective view of my bow-drill stock.
Figure 2 shows 'in elevation vthe stem D'and-the pulleys AB, with the four stringsH H H" H" a.ttnched Figure 3 is a section of one of the pulleys.
Figure 4 is "a plan of one ofthe pulleys.
YThe bow-drill stock isso arranged by means of the pulleys A B and their adjunct, that the reciprocating motion of the bow will produce a constant circular motion of the stem always in the same direction, as has been fully explained in the specific-ation of Letters Patent granted to me, August 27, 1867, and numbered 68,071.
The pulleys-A and B are each provided With two grooves, as shown in lig. 2. Each of' these grooves has string, one end of which is permanently attached to the pulley. I attach theend ofthe string, by passing it vthroughs. smallhole, z, figs. 1, 3, and 4, and making n. knot, Abut the end of the string Ina-y be attached to the pulley in a variety of ways. l
invention consists in using four strings, one end of' en ch of which is attached to the bow, while the other ends are attached to the pulleys.
The advantage of nay-method Yof' stringng'is that there can be no slip.
Having thus described my invention, I will noivrproceed to set forth my claim.
What I claim as my invention, and desire to secure by Letters Patent of the United States, is-
. Combining and arranging the four strings H H H H" 4with the pulleys A B, .when said pulleys Work substantially as4 described, and for the purpose set forth..
' D. FRANK HARTFORD.
