NAP-RESTORING DEVICE.

Application filed December 19, 1924-.. Serial No. 757,023.

This invention relates to improvements in devices for restoring nap to cloth, the de vice herein being particularly adapted for domestic use. p An object is to provide a device in which perfect control of the cloth-engaging por* tions of the nap-producing or raising element can be obtained, and by which the working edge of this element can be brought toward, into or away from the cloth in micrometric degree, enabling the operator to produce nap of exactly the desired length or texture and, thus to accurately control the nap restoring operation.

Another object is to provide a nap restoring element, as a blade, which can be attached to an ordinary commercial type of safety razor handle or like mount, in lieu and manner of a razor blade, so that the mount acts as a movable rest or support to be drawn along the goods during the renapping operation, and as a fulcrum about which the mount may be rocked for bringing the working edge of the nap restoring r element toward, into or away from the goods.

Another object is to provide a mounting for the blade, which has a rounded working edge, and in which the nap restoring element, when attached to the plate, is slightly spaced away from the rounded working fulcrum edge or bears a tangent relation to the edge, and is therefore spaced outwardly therefrom.

A more specific object of the invention is to provide a reversible razor-like blade which may be attached to a razor handle of a commercial type, the blade having along each of two parallel sides a straight row of nap raising or producing teeth each of different iineness, whereby either edge of the blade may be used and the blade substituted for the ordinary razor blade to act as a cloth surface renishing tool, controlled and manipulated by the mounting and handle.

Another object is to provide a device for the above purpose which may be cheaply manufactured either providing ak bladefor attachment'to a safety razor of the ordinary type, or as a combination blade and holder constructed in accordance with the 1teachings of this invention.

Other objects and certain advantages will be disclosed in the description of the drawing forming part of this specification, in which:

Figure l is a side view of the device partly in section, shown in working position, and illustrating the manner of att-ach-v ment of the blade to a safety razor handle of a commercial type.

Figure 2 is a face view of the blade.

Figure 3 is a cross section of the blade on line 3 3 of Figure 2.

Figure flis a vertical longitudinal section of the assembled device on line 4-4 of Figure l.

The device comprises a curved plate 1, having a convex face 2, and also a concave face from which extends a handle 3. The plate is substantially rectangular, and its two longer parallel edges are provided with inwardly extending teeth or prongs 5. My improved blade is attached upon and against the convex face 2, is also rectangular, and is of slightly less width than that of the convex face between the longitudinal `rounded fulcrum edges 4. The blade has two rows of knife edge teeth 8, A9, each of different lineness or spacing, and when the blade is attached, the tips of the teeth lie parallel with respective or corresponding fulcrum edges d, with the teeth tangently related to the rounded edges 4, and preferably spaced inwardly therefrom as shown in Figure l. The relative sizes of plate and blade are such that when the blade is attached flatly against the concave face, the rows of teeth assume the tangent relation, thus causing the working points of the teeth to be slightly spaced away from the working edge. The teeth are, however, preferably beveled as at l() inthe manner of the edges of a safety razor blade, and the blade herein has generally the form of that type of blade, except, for the toothed edges. The blade is secured upon the plate preferably by a concavo-conveX retainer 11, which has centrally of its concave side, a threaded stern 12 passing through openings 17, 18, in

lill) blade and plate and engaged with correspending threads oi' the handle 3, so that when the parts are assembled, and the handle screwed to position, the retainer is drawn against the blade and said blade is iiexed and securely held. The extent of clamping actionxinay be 'varied' to flex the blade in the desired degree Vand therefore correspondingly vary the degree of tangency relative to the conve'xjface or rounded fulcruin edge. The retainer also has two projecting pins 13, spaced equidistantly ateacli side of the stein 12, and these pins traverse corresponding openings '14, 15, in

plate. and blade.

Any 'convenientnieans of'fastening the blade may be used as Vwell as otherfornis of Yfulcruin plate anfd"han`dles for operating the saine,`the important fea-ture beingthe relative disposition of the fulcruni Yedge of the lade, ywhereby adjustment of the plate v`plate and the toothed edge or edges of the labout its fulcrurnedge or side varies the Vextent of engagement between the teeth and cloth. y

The blade may be Aattached inany preferred manner sothatthe above relation l'between the fulcruin plate and the blade is obtained, and the plates maybe sold singly or in sets, either with 'or without holders land inodifiedlin shapeto conform to other types of safety razor holders or handles.

Having described iny invention, I claim: 1. In a device of the class described, a

platehavinga straight edge, and a blade holder, said blade having straight rows 'of teeth on respective opposite parallel edges.

5. In a device ofthe class described, a plate having a straight edge, anda blade having a straight row of teeth along one of said edges, said bladeattached to saidv plate with Vitsstrahght row of teeth adjacent the straightI edge of the plate yand spaced outwardly frein the face' of the plate.

6. In a device of the class described, aV

plate having va straight rounded edger anda y blade havinga straight row'of teeth along fone edge, 'said blade attached vto said `plate withthe row r'of teeth"overlying the 'curved `edge of they plate tangent thereto.

7. In a device of the class described, a plate having a straight rounded edge and a blade having two parallel straight edges and teeth along said edges with one row of teeth overlying the rounded edge of the plate tangent thereto.

8. A plate having a straight edge and a blade having a straight row of teeth, said blade attached to said plate with a row of teeth adjacent `and parallel with said straight edge and spaced outwardly therefrom.

9. In a device of the class described, a plate having a straight rounded edge, and a blade having a straight row of beveled teeth, saidplate flatly attached to said plate plate and spaced inwardlyfrom the edgev and outwardly from the convex surface,

whereby when the plate is i'ocledl about its straight edge as a fulcruin the teeth are adjusted to fard or away from the fabric.

11. In a device for restoringthe nap of fabric, a curved plate of substantially rectangular configuration providing opposite parallel rounded edgesas fu'lcrunisfor roelc ing'the plate when one of the edges is engaged with the fabric, a blade attachedto the convex side of the plate,`said blade having straight rows of teeth parallel with, `overlying and tangent to the rounded edges of the plate.

12. A flexible blade of substantially the dimensions of a safety razor blade, including spaced openings for attaching the blade,

said blade having straight rows of beveled teeth in lieu of razor edges, whereby the blade can be attached to the razor mounting or holder and manipulated for a nap restoring operation by placing Aone straight edge of the mounting against the goods as a fulcruni and rocking the device in varying degree to vary the engagement of the teeth with the goods. Y

13. In a device of the class described, a plate 'having a'straight working edge adapted to rest upon the goods and to actas a fulciuni, a blade' attached flatly against the plate, said blade having a straight rowy of i-loeveled teeth at one edge andspaced inwardly from said edge and outwardly from the face of the plate, whereby when rocking the plate 'about the working edge the 'degree of engagement of the teeth with the goods` can be varied and controlled While drawing the plate across the goods.

14:. In a device of the class described, a plate having a straight edge rounded 5 throughout its length, a blade attached to one face of said plate having a straight row of teeth along one edge, the tips of the teeth lying tangent to the rounded portion of tho straight edge, and spaced outwardly from the rounded surface, and means for rocking the plate about its yrounded straight edge as a fulcruin to adjust the teeth toward, into or away from a fabric.

In Witness whereof, I hereunto subscribe my name.
