DEVICE FOR ATTACHING WINDOW-SHADES TO ROLLERS.
SPECIFICATION forming part of Letters Patent NO. 766,257, dated August 2, 1904.
Application filed March 19, 1904:. Serial No. 198,953. (No model.)
To 1077/ 775 W come these defects, make the plate more easily 5 Be it known that I, \VILLIAu D. JANES, a applied to the roller, and to increase its holdcitizen of the United States, residing at Sagiing power, I have devised theimproved fastennaw, in the county of Saginaw and State of ing shown in the accompanying drawings, hlichigan, have invented certain new and useforming a part of this specification.
ful Improvements in Devices for Attaching Figure 1 is a side view of a grooved roller 55 lVindow-Shades to Rollers; and I do hereby with the shade in place, one end of the shade declare the following to he a full, clear, and being turned back to show the groove and my exact description of the invention, such as fastening device applied ready for driving. IO will enable others skilled in the art to which Fig. 2 is an end view of the same. Fig. 3 is it appertains to make and use the same. an end view showing the fastening device 60 This invention is a device for attaching winpressed in place ready to be flattened by drivdow-shades to rollers, and relates more paring. Fig. 1 is a side view of ashade fastened ticularly to that class of such devicesin which to its roller. Fig. 5 is an end view of the the roller is longitudinally grooved and the parts shown in Fig. 4. Fig. 6 is an enlarged end of the shade is fixed in the groove by perspective of the fastening device ready to 5 means of small bowed plates of sheet metal be driven. Fig. 7 is a similar view showing having teeth or prongs formed on their lonthe device forced into place. Fig. 8 is a pergitudinal edges engaging the walls of the spective of a modified form of my improve- 2o groove to fasten the shade in the groove by ment.

the bowed plate is flattened or its curvature provided with the groove (ar, to which the reduced by driving. It will be noted that this shade is attached by means of my improved class of fastening operates by flattening the fastening device, which consists, as above debowed plate, thus spreading its longitudinal scribed, in the usual bowed plate 1, having edges and forcing the teeth downwardly and outwardly-extending teeth or prongs 2 2, 75 outwardly in opposite directions. In flattenadapted to enter the walls of the groove Gr ing the plate it is of course necessary to bend when the plate 1 is flattened, as shown in Figs. the metal. During the flattening of the plate 5 and 7.
while the teeth are entering the opposite walls The main object of this invention is to inof the groove the resistance of the two walls sure that the oppositely-disposed prongs 2 2' 30 must be substantially equal, else the teeth will shall enter the walls equally. This is accomnot enter the opposite walls equally. plished by providing the bowed plate 1 near It is found in practice that unless considerits middle with one or more downwardly-exable care is taken to accurately adjust the tending prongs 3, adapted to drive straight prongs of the grooved plate relatively to the into the face of the groove (l, and thus guide 5 groove of the roller and unless the driving the middle part of the plate 1 straight down force is applied directly above the center of to the middle of the groove (1 so that the opthe plate the prongs on one side will go deeper posing prongs 2 2 as they straighten out un- 4 into the walls of the groove than those on the der the driving force will enter equally the other side, often resulting in failure to grip opposite walls of the groove G instead of en- 9 on one side and reducing or destroying the' tering them unequally, as was frequently the holding power of the plate. 1f driven over case before the prongs 3 were used. on the shade side too far, the full width of the The prongs 3 may be lixed to the concave plate cuts through the shade, and the shade is side of the plate 1 in any suitable manner; but
apt to tear out at that point. Also if driven when the prongs 3 are formed as shown in 9.5 7 over too far to one side the prongs go clear the drawings by slitting the plate 1 and bendthrough into the bore of the roller and intering the prongs 3 down, as shown in Figs. 6 fere with the action of the spring. To overand 8, an additional advantage is attained.
This is evident when it is remembered that the prongs 2 2 are forced outwardly by the act of straightening or flattening the plate 1. The greatest bending occurs in the middle of the plate, and if the plate is made of sheet metal having considerable elasticity it has a tendency to bow up or loosen after being driven and also by its resistance to straightening while being driven tends to tear the wood and make holes in the walls of the groove Gr larger than the prongs 2 2, thus reducing its grip on the roller.
' By forming the prongs 3 from the body of the plate 1, as shown in Figs. 6 and 8, the cross-section of middle portion of the plate is reduced, permitting the plate 1 to flatten easier while being driven and allowing the prongs 2 2 to follow their natural tendency to enter straight into the walls of the groove, thus making holes in the roller of the same size as the prongs and greatly increasing their holding power. The reduced weakened crosssection of the plate 1 can exert less tendency to bow up after being driven, and the prong 3 furthermore operates as a nail or spike to that the farm, number, and location of these prongs may be varied to some extent without departing from the spirit of my invention, which resides, essentially, in the guidingprong adapted to direct the body of the plate fair down upon the groove, while the prongs 2 2 spread out in opposite directions and enter the walls of the groove under the bending action of the plate 1 as it flattens while being forced down upon the shade.
What I claim as my invention, and desire to secure by Letters Patent, is as follows:
1. In combination with a bowed plate having opposite edges provided with outwardlyprojecting teeth adapted to enter the opposite walls of a longitudinal groove in a shaderoller when the plate is flattened; means for guiding the middle portion of the plate during the flattening action, comprising an inwardly-projecting prong fixed to the under side of said bowed plate, for the purposes set forth.
2. In combination with a bowed plate having opposite edges provided with outwardlyprojecting teeth adapted to enter the opposite walls of a longitudinal groove in a shade-roller when the plate is flattened; means for guiding the middle portion of the plate during the flattening action,comprising an inwardly-projecting member formed by slitting the plate to form a prong and bending in the prong so formed.
' In testimony whereof I affix my signature in presence of two witnesses. 1
