JOHN COURTENAY, OF AVIEMORE, CAPE COLONY.

FLAT-IRON.

To all whom t may concern:

Be it known that I, JOHN COURTENAY, a subject of the King of Great Britain, residing at Aviemore, Elsies River Halt, Cape Colony, South Africa, farmer, haveinvented new and useful Improvements in Flat-Irons or Hand-Irons, of which the following a specification.

This invention relates to improvements in irons for smoothing in which a roller is combined with a flat iron; and consists in arranging' the roller resiliently, so that by changing the pressure upon the iron, the flat surface may be brought into contact with the material to be smoothed, or the iron may be allowed to run freely on its roller.

The invention is particularly applicable to hand irons, though it may be made on a large scale for such purposes as smoothing asphalt. If desired the roller may be so mounted as to be easily removable; and in some forms of construction it is convenient to employ also a removable handle as is often done with ordinary flat irons.

In the accompanying drawings-Figure l is a view in side elevation of my improved iron showing part of the mechanism in dotted lines; Fig. 2 is a transverse section of the same; Fig. 3 is a side view partly in elevation and partly in section of a modilied form of my invention; Fig. 4 is a side elevation of still another modification; Fig. 5 is a top plan view of the roller holding device shown in Fig. l; Fig. 6 is a side elevation of another modification; Fig'. 7 is a top plan view of the roller holding device shown in Fig. G, and Fig. S is a view of the spring pressed catch, 25.

The forni of construction shown in F igs. l and Q suilices to make clear the essence of the invention. As may be seen from those figures the flat iron proper a has an incomplete cylindrical recess b cut in it, and in this recess there is mounted a roller c. Preferably the recess should bc made more than semi-cylindrical, and if its lower opening is of less width than the diameter of the rollers c, it will naturally prevent the roller from being protruded too far. The recess may or may not be of such size as to divide the body a of the iron into two parts, but in the former case it is convenient to join the two parts of the iron by arches c.

Application filed July 17, 1909.

Patented Jan. 11, 1910. serial No. 508,135.

The roller c has projecting pivots e at each end and these engage in bearings formed in the lugs f upon the spring plate g. The ends of this spring plate are made straight as shown and are slotted at h to receive screws 7c which enter the arches cZ. These screws serve to guide the spring g in its upward and downward movement. The center of the spring g engages beneath a bridge piece m which in the example shown extends between the two uprights of the handle n of the iron.

If the handle is to be made detachable, recesses p, g are provided in the upper surface of the iron. One of these is just of a size to receive the upright r at one end of the handle a. The other recess g is made slightly larger and is rather more undercut. The upright s has pivoted at its lower end a catch t which is pressed by a spring so as to engage in the undercut portion of the recess Q. Upon the upright s there is further pivoted a lever o pressed by a spring fw, the upper end of this lever lying near the end of the handle n. It will readily be seen that by pressing the lever yv toward the handle a the small catch t is turned about its pivot and its foot is withdrawn from the undercut portion of the recess g. When this is done the handle can be lifted out from the recesses. As will be seen the removal of the handle immediately takes away the spring pressure from the roller. It should be noted that the screw passing through the bridge piece m and the spring g, may engage with the spring g so that it has to be unscrewed before the handle can be removed or it may be omitted altogether.

It will be understood that the invention may be employed with irons of any type whether they be simple solid flat irons, boX irons, spirit irons, gas irons or electric irons. Naturally in the case of the latter types of iron some modification will be necessary in the arrangement of the heating apparatus, but the necessary rearrangement will be, readily apparent to those acquainted with the art. The material of the roller may be varied according to the purpose for which the iron is to be used, and the price at which the iron is to be sold. It may be simply of iron, or it may be nickel plated, or it may be of copper and so forth. Moreover it may be constructed of solid metal or may instead be hollm It is sufficiently clear from the remaining examples illustrated th at many modications may be made in thc details of construction of the iron. In the forni shown in Fig. the roller c is secured to an arched plate g as before, but this plate now guided in slots formed at the sides of the iron7 though not extending quite to its base. The plate f/ need not in this case be itself springy but a spring '2 may be secured to some part of the handle7 for example, to the upright r in the manner indicated. One leg of this spring 2 rests upon the arched piece y while the other bears against the end of a screw 3 which can be moved in and out to adjust the pressure of the spring. Alternativel;7 a simple leaf spring such as a piece of fairly stiff clock spring could be employed. 1n this example the handle is shown as permanently secured to the iron proper7 but it may of course be detachable as in the previous example. The middle or grip part of the handle is surrounded as indicated, by a sheath of wood or other non-conductor of heat.

Though it is convenient to have the roller in the center of the iron, as in this position it more easily lifts the iron from the material which is being treated as soon as the pressure of the hand is released and so allows the iron to run back with ease. it may be desirable for some purposes to secure the roller at one end of the iron. and this is perhaps the better position where it is intended that the roller may be detached from the iron and the iron used alone. A construction of this kind is shown in Figs. 4 and r1`he roller is in this case mounted in a frame 5 which carries two screws t5, the ends of which enter recesses in the ends of the roller r,- and form its bearings. rShe frame 5 has an extension 'T at the end of which a perforated rib 8. This rib lies between two similar perforated ribs 9 formed upon the upper surface of the iron. and a pin 10 passes through all three ribs so as to forni a hinge and malte the frame a radius rod. The cylindrical recess 7; is now formed at the end of thc iron c. the upper surface of which is arched. as indicated. y

The handle n may be made detachable as before, one upright entering the recess p in the arch which projects through the opening` of the frame 5. and the other the recess j at the front of the iron. The fastening device is in this case slightly diti'erent as it consists of a single lever 1l pivoted to the upright .s of the handle and pressed ontwardly by a leaf spring tu so that its end engages beneath the undercut lug l2 upon the front of the iron. rl`he handle is therefore released in this case by pressing the thumb piece l?) away from the handle. The spring 2 is in this case pivotallfY attached to the upright r of the handle. and bears against the projection 19 on the extension T of the frame The object of this arrange ment is to allow of the spring pressure being 'released when the iron is pnt on the stove for heating. so that it will rest upon its tial' surface. lt will be seen that if the spring be lifted so as to be disengaged from the projection 127. it will no longer press down the roller.

ln Figs. (3 and T another form of iron having the roller at the back is illustrated. ln this case the recess is practically absent and the roller could be attached in substantially the manner here illustrated to an ordinary iron. The roller is mounted in bearings in a box shaped frame il. which has perforated lugs l5 forming the hinge with a single central lng in the upper surface of the iron 1.'. spiral spring 't3 is employed to apply pressure to the roller. and this extends between a projection 1T on the frame lsand a screw 18 passing through the handle snpport. VBy turning the screw the pressure of the spring may obviously be adjusted.

It will be clear that the invention is not limited to the forms of construction thus described by way of illustration. lt is only A intended that the constructions shown shall indicate some of the possible variations in the details of the iron. Naturally the method of mounting the spring in one of the constructions shown might be combined with the method of mounting the roller in another of the constructions and so forth. Such modifications will, however. be readily apparent to the expert and need not be further detailed.
