RATCI-IET-NHEEL AND THE LIKE.
LMMLQGG.
To all whom it may concern:
Be it known that I, EDWARD E. HARRIs, a citizen of the United States, residing at Valliant, in the county of McCurtain and State of Oklahoma, have invented certain new and useful Improvements in Ratchet- Vheels and the like, of which the following is a specification.
This invention has particular reference to the ratchet wheels of curtain rollers and fixtures; its immediate object being to provide a-ratchet wheel-which can be readily attached to the roller, and which when properly applied will be fixedly attached to such roller and be incapable of rotation thereon, and will also act as a bond or tie for the end of the roller to prevent splitting or spread ing thereof; thus providing an extraordinarily serviceable ratcheted roller capable withstanding long and heavy use with safety, and enabling same to support more weight by virtue of the peculiar snug fitting of the ratchet wheel to the roller.
While the invention is especially adapted for use with rollers for shades, maps, and the like, it is not restricted to a ratchet wheel, as it is well adapted for securing pinions, or disks, to the ends of rollers, shafts and the like.
As shown in the accompanying drawingsFigure 1 is a perspective view showing the roller, ratchet and gudgeon pin in position for assembling. view of the ratchet fitted on the end of a roller. Fig. 3 is a similar view with the gudgeon pin in position. Fig. 4 is a side view of Fig. 3. Fig. 5 is a longitudinal section on line 55, Fig. 4. Fig. 6 illustrates a ratchet wheel embodying the invention and having ordinary ratchet teeth.
The ratchet wheel 1 may be of any desired diameter and is preferably flat; and may be stamped or cast. It is provided with an annular opening 1 substantially corresponding in internal diameter to the external diameter of the roller to which it is to be attached; or to a cylindric projection on the end of such roller. This ratchet wheel is provided with four inwardly projecting equi-distant radially disposed arms or spokes 1 which are preferably straight-sided; and
their inner ends preferably do not quite come into contact with each other, leaving a central opening 1 at the center of the wheel. The arms or spokes 1 are in the Specification 01 Letters Patent.
Application filed June 18, 1913.
Fig. 2 is an end Patented July 21, 1914.
Serial No. 774,455.
plane of the wheel, and are adapted to engage similarly disposed, intersecting chan nels 2" in the end of the roller gr shaft 2 to which the wheel is attached. These channels 2 may be formed by forcibly pressing the ratchet wheel into the end of the roller, if of wood, or can be previously cut in the end of the roller by a saw; the ribs 1 being practically as wide as the kerf of an ordinary saw.
The ratchet wheel may be secured in of the shaft or roller as shown, with the arms 1 seated in the notches or slots 2" and the outer end of the roller being flush with the outer surface of the ratchet wheel. The arms and notches effectively prevent relative rotation of the wheel and roller, and the end of the roller is confined within the rim of the wheel, which forms a band or collar around the end of the roller and effectively prevents spreading of the latter.
The ratchet wheel may be secured in position against endwise movement on the roller by means of an ordinary curtain roller gudgeon pin 8 which can be driven into the end of the roller, when of wood, in the usual manner through the central opening 1 in the ratchet wheel; and said stud has an annular collar 3, as usual, which projects over the inner ends of the arms 1* and holds the wheel in position against the end of the roller and also prevents any of these arms being bent outwardly, or projecting outwardly, so as to interfere with any object adjacent the end of the roller, or side of the ratchet wheel.
The ratchet wheel shown in Figs. 1 to 5 is preferably formed with double faced teeth 1; and such a ratchet wheel can be put on the roller either face outermost, and it does not matter which face of such ratchet wheel is outermost, as it will always be in position to operate efficiently and be properly engaged by the pawl (not shown).
In the form shown in Fig. 6 the ratchet wheel has ordinary ratchet teeth. and such wheel must be placed on the roller 2 with the teeth pointed in the proper direction, otherwise they would not properly engage the pawl. When the roller is of wood the ratchet wheel can be pressed onto the end of the roller and the arms bedded therein, thus establishing a rigid connection therebetween and having a smooth surface on the end of the roller. If the roller is of metal the kerfs or channels 2* must be out before the wheel is fitted thereto. If it is desired to apply the ratchet wheel to a roller or shaft of larger diameter than the opening 1 in the wheel, the end of the roller or shaft should be reduced to the diameter of this opening so that the wheel may be fitted thereon. When applied to a metal roller or shaft pin 3 might be substituted by a screw; and obviously a screw-threaded pin could be used in place of a nail pin; but the invention is especially designed and adapted for use with the ordinary gudgeon pin.
The ratchet wheel shown in Figs. 1 to 5 is reversible and operates equally well either face out or from either side, thereby eliminating the caution necessary in applying the ordinary ratchet wheels to rollers.
What I claim is: 1. In combination a roll having radially disposed recesses in its end, a flat disk-like member attached to the recessed end thereof having a circular opening to receive the end of the roll and provided with arms projecting into said opening and seated in said recesses in the end of the roll.
2. In combination a roller having radially disposed recesses in its end, a flat disk-like member on the recessed end thereof having a circular opening to receive the end of the roller and provided with radially disposed arms projecting into said opening and seated in the corresponding recesses in the end of the roller; and an axially disposed device passing through such member and engaging the end of the roller.
' 3. In combination a roller having radially disposed recesses in its end, a flat wheel having an opening fitted to the end of vthe roller, and radially disposed arms extending into said opening and seated in the corresponding recesses in the end of theroller; with a device extending axially through the wheel and engaging the roller.
4:. In combination with a shade roller having shallow radial channels in its end, a
flat ratchet wheel having an opening fitted to the end of the roller, and having radially disposed arms extending into said opening and seated in the corresponding channels in the end of the roller; with a gudgeon pin extendingaxially through the ratchet wheel and engaging the roller.
5. A reversible ratchet wheel for the pur pose specified comprising a flat disk-like member having squared or double faced teeth on its periphery,a large axial opening, and a series of radial arms extending-into said opening but connected at their inner ends to leave an axially disposed space for the passage of a retaining device.
6. In combination with a roller having shallowiradial channels in its end, a fiat ratchet Wheel having a circular opening fitted to the end of the roller, and having radially disposed arms projecting into the opening and seated in the corresponding radially disposed channels in the end of the roller, and a gudgeon-pin passing axially through the ratchet wheel and engaging the inner ends of the arms and the roller, substantially as described.
In testimony whereof I aliix my signature, in presence of two witnesses.
