T0 aZZ whom it may concern:
Be it known that I, EDMUND F. HARTSHORN, a citizen of the United States of America, and a resident of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvementsin Spring Shade-Rollers, of which the following is a specification.
This invention relates to a novel method of attaching the coiled spring mounted on the spindle to the metal spindle tip or spear connected to the end of the spindle, the outer end of which enters the square or notched window-bracket and holds the spindle stationary as the roller turns around it under the manipulation of the shade. Heretofore the methods adopted for attaching the end of the spring to the spindle in this form of spring-' roller were either by thrusting the end of the spring through a hole formed in the end of the wooden spindle and a similar hole formed in the end of the spindle-tip inserted in the end of the spindle and bending the spring around the spindle or by thrusting the end of the spring through a hole cast or punched in the metal spindle-tip beyond the end of the wooden spindle and tying it by bending it at that point. In these methods of tying or fastening the end of the spring it is necessary to manipulate or bend the spring in such manner as to disarrange its natural cycloidal curves, preventing the best results in the operation of the roller and causing the construction to be less economical than by the method here described. In this improvement the spring-is attached to the spindle just as it comes from the mandrel around which it is coiled and is held between the forked ends of the spindle-tip, as described below, by which the latter is connected to the spindle and all manipulation or bending of the spring is avoided, and, furthermore, the desirable metallic bearing is furnished for the spring under all circumstances.
In the accompanying drawings, forming part of this specification, Figure l is a complete View of the spindle and spring and spindle-tip connected thereto, showing the improved method of attaching the end of the spring to the spindle and one of the usual methods of attaching the other end of the spring to the bore of the roller. Fig. 2 is a transverse section of Fig. 1 through the line 2 2. Fig. 3 is a View of the end of the coiled spring. Fig. 4 is a view of the end of the spindle and spindle-tip and spring, showing a modified construction of the spindle and attachmentof the spring. Fig. 5 is a transverse section of Fig. 4 through the line 5 5. Fig. 6 is the same as Fig. 4, showing afolded spindle-tip; and Fig. 7, is a detached view of the spindle and spindle-tip shown in Fig. 6.
1 is the spindle.
3 is the spring as it comes from the mandrel, having its outer end 4 bent across the plane of its coils, as shown in Fig. 4, and 5 is the spindle-tip.
In assembling the parts the spindle isinserted in the coiledspring atthe inner end of the latter or end opposite the bent end 4and pushed through until the bent end 4 rests on the end of the spindle or enters the cleft2 in the end of the spindle in the modified construction shown in Figs. 4and 6. The other or inner end 6 of the spring in the construction shown in the drawings is then attached to the metal bung 7, in which the spindle loosely rests,and which is fastened to the roller within the bore of the latter by the prongs S. To the outer end of the spindle is connected the spindle-tip 5, which in this improvement is provided with two forked projections 9,-
Which fit over the end of the spindle and serve to attach the tip to the latter. This forked spindle-tip may be cast ready for attaching to the spindle, as in Figs. 1 to 5, or folded from a sheet-metal blank, as in the constructions shown in Figs. 6 and 7. As the spindletip is connected to the spindle the forked projections 9 are placed over the end of the latter in such manner as to embrace the end 4 of the spring resting on the end of the spindle or cause it to lie between them, as shown in Figs. 1 and 2. The end of the spring is now held'between the forks of the spindle-tip, so as to impinge or bear against the forks under the operation of the spring, and the attachment of the spring to the spindle is complete. The operation of connecting the spin= dle-tip to the spindle thus fastens or ties the spring to the latter, and the attachment is effected without the necessity of manipulating the spring in any manner;
Where the spring is thus held by the forked projections on each sideof the cleft, the splitting of the spindle by the spring, which was apt to occur when the spring was held merely by the cleft in the previous construction, is
avoided. V t
In the folded spindle-tip shown in Figs. 6
and 7 the tip is attached to the spindle not only by the projectingends 9, but by the innor web 10 of the tip, which fits into the cleft 2 in the spindle. As will be seen from Fig.
6, the opposite edges 11 of the projecting ends,-
9 are so constructed that when the tip is in place on the end of the spindle, with the web 10 in the cleft in the latter, these edges 11 will lie along the edges of the cleft around which the spring curves and in such manner that the spring bears or impinges against their opposite edges. In this improvement the attachment of the spindle-tip furnishes the bearing for the'spring on the latter. The spring therefore can rest directly on the end of the Wooden spindle or in the cleft and the desirable metallic bearing for the spring be furnished by the spindle-tip when connected with the sp n e- While the construction above described is that which I deem preferable, the form of tip and connection of spring with the spindle may be variedfro n that shown without departing from the spirit of myinventionso long as the attachment of the spindle-tip with the spindle furnishes the bearing for the endof the spring or so long as the bearing is furnished by the spring impinging or resting against the diagonally-opposite edges of the forked projections of the spindle-tip.
What I claim is V 1. In a spring shade-roller, in combination,
a spindle; a metallic endmember attached thereto provided with forked projections by which it isjsecured to the end of the spindle; and a spring mounted on the spindle, one
end of which is adapted tobe secured to the roller, andthe other end of which is connected to the spindle, and held andrests between the forked ends of the end'member whereby the spring impinges and bears against the "diagonally-opposite edges of the forked projections, substantially as and for the purposes described. I
2. In a spring shade-roller, in combination,
a spindle 1; a spindle-tip 5 provided with the forked projections 9 whereby it is secured to the end of the spindle; and aspring 3 mounted on the spindle, the inner end of which is adapted to be secured-to the roller, and the outer end of which is connected to the spindle and held and rests between the forked projections9 of the spindle-tip, whereby the spring impingesand bears against the diagonally-0pposite edges of the forked projections, sub stantially as and for the purpose described. 3. Inaspring shade-roller, in combination, a spindle 1, having the cleft 2 in one end; an end memberattached thereto provided with forked projections 9 whereby it is secured to the end'of the spindle; and a spring mounted on the spindle, one end of which is adapted to be secured to therolle-r, and the other end of which rests in the cleft 2 in the spindle, and is held between the forked projections 9 of the end member, whereby theispringin the cleft impinges and bears against the diagonally-opposite edges of the forked projection substantially as and for the purpose described. 4. In aspring shade-roller, in combination, a spindle 1, having the cleft 2 in one end,an end member attached thereto, provided with forked project-ions 9 and inner web 10 adapted to engage with the cleft '2 in the spindle,
qwhereby the member is secured to the spin dle; and a spring mounted on the spindle, one end of which is adapted to be secured to the roller, and the other end of which rests in the cleft 2 in the spindle, and is held between the forked projections 9 of the end member, whereby the spring in the cleft impinges and bears againstthe diagonally-opposite edges of the forked projections, substantially'as and for thepurpose described.
