LOUIS B. GIRARD, or Los ANGELES, CALIF oItNI'A, AssIGNoR, DY DIRECT AND MEsNE CALIFORNIA, A CORPORATION OF CALIFORNIA.
WINDOW-SHADE TACK.
To all 'whom it 'may concern: p
Be it known that I, LOUIS/B. GIRARD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and j State of California, have invented a new and useful Window-Shade Tack, of which the following is a specification.
Thisinvention relates to a tack adapted for attachin window shades to rollers, and the main' obJect of the invention is to pro'- duce a tack of the -character .described which may be stamped from a `strip of sheet metal without wastlng any of the material.
l Another objectl is to provide a tack of this character which is adapted tobe formed and driven automatically. by a machine.
"Referring to the drawings Figure -1 vis 'a perspective view of a portionof the strip of metai, showing the tack asformed onthe end thereof by the machine before the removal of the tack from the strip. Fig. 2 is a per- V spective view of the completed tack. F1 3 is a sectional view through a shade ro er and tack. Fig. 4 is a plan view showing a series of tacksv attened out and `laid together, the object of the view being' to show that a rear elevation of thejtack.
rllhe tack is formed from a strip of metal 1 and consists. of a head having a V-sliaped` notch 3, a'down-turned front 'prong 4 and two rear prongs 5. t front prong 4 are two shoulders 6 which act to grip the shade when the tack is driven. 0n each side `of the notch 4 adacent each rear prong 5 is a shoulder 7 an the shoulders also serve to when the. tack is driven. The notch 3 is produced as a result of forming 'the front prong 40 4 of another tack. Each slde` ofthe head 2 is beveled, asat 8, whichthe result' of forming the A specification of Letters ratent. Application ledtpctober 1 7, 1908.
there is no waste metal. Fig. 5 is portions each .side of the single prong.
. On each side of the` grip the shade roller beveled portion is Patented Dee. 7,1909. Serial No. 458,285.
4 another tack. All of the metal in the strip is utilized to the fullest extent. The notch 3V furnishes the metal for the front prong and yet does not weaken the tack unduly as plenty of metal is left in the head. The prongs are well distributed which leaves suiicient material in the window shade between the perforations to prevent the shade from easily tearingv at the points of fastening. 5
I am aware that' shade roller tacks have been constructed with two prongs at one side and one rprong at the other, but, so far as I am aware, I am the first to produce a shade roller tack such as Aereinshown which has a maximum gripping area, with its prongs lspread well apart and which does not leave any waste metalf in the sheet or strip from which it is cut, all of to the fullest extepta v`What'I claim is: l p 1. A window shade tack comprising a head formed of sheet metal with a prong on one sideand .having a notch in the opposite side said notch'being substantially the same size as said prong, and two prongs on the notched side, said head havingztwo beveled a2. A shadebroller tack comprisin a single piece of sheet metal formed with a ead having a notch 3, and a prong '4,- said notch and pron having the lrelative areas as shown', said ead having two prongs andtwo-cutaway portions 8 ofv substantially the comparative dimensions shown.
In testimony whereof; I have hereunto set my hand atl Los Angeles, California. this 10th day of OctobeiI 1908.
