PATENT? OFFICE HARRY o; WARNER, orjKeNsAs GITY, MISSOURI HAIR TRIIVIMING ATTACHMENT FOR SAFETY RAZORS fa ncauon filed July 13,

This invention relates to hair trimming attachments for use in combination with the ordinary safety razor'and the primary ob ject of the invention is to provide a simple, for the trimming of hair which includes means for progressively cutting the hair shorter as the end of the stroke is reached.

One of the objects of the invention is the contemplation of a new article of Imanufacture in the form of a hair trimming guide for safety razors, whlch guide mcludes a plurality of movable members each having a cam facethereon, whereby to allow the cut ting edge of the blade to progressively move toward or from the head as hair isbeing cut.

An even further object of theinvention is to provide a hair trimming attachment for safety razors which may be easily combined 80 bodied parts that are strong and durable,

with the well known double-edged safety razor and which may be manufactured and sold as an accessory, attachable to such safety razors without altering the same.

Besides the more specific objects of the invention which will appear during the course of the detailed specificatiomthe invention contemplates an attachment of the above mentioned character wherein is emcheap to manufacture bled. In the drawings:

Figure 1 illustrates and quickly assemthe use of a safety razor and hair cutting attachment which is made in accordance with the present invention.

2 is an enlarged front view of razor and attachment.

Fig. 3 is an enlarged perspective view of the hair trimming guide showing the same entirely removed from combination with a safety razor, and,

Fig. 4 is an enlarged vertical cross section through the completely assembled device, taken on lineIV-IV of Fig. 2. j

Like reference characters designate similar parts throughout the several views of the drawings and the numerals 6 and 8 indicate an upper and a lower plate respectively of the ordinary well known double-edge along: opposite sides 1931; Serial No. 550,381

safetyrazor, between which plates 6 and 8 is interposed blade 10, having cutting edges 12 thereof. As is the custom" in razors ofthis' character, a handle 14: is provided to engage a portion of the upper plate 6 and to bear against the lower plate 8, whereby blade 10 is drawn tothe suitable curve. In some instances a longitudinal rib .16 is formed'along the lower face of plate 8.

As illustrated in'F 3, the attachment proper is formed of a frame 18 having a longitudinal slot 20 formed therethrough for the passage'of depending neck 22, integral with plate 6. When a rib. 16 forms a part of lower plate 8 it enters slot '20 and the end-of-handle 14: bears against the lower face of frame 18 to hold the sameagainst the under side of plate 8 asillustrated in Fig. 4. A bearing 24is formed adjacent each end respectively of frame 18, through which passes connecting bar 26. This bar 26 is journaled in bearings 24 for pivotal movement and extends beyond the bearings Where it supportsthe guides 28. Guides 28 are rigidly mounted upon bar 26 and rotate therewith. Their bearing edges 30 are arcuate and serrated and when theattachmentis in place this edge 30 is concentric to the cutting edge 12 of blade 10, as shown in Fig. d.

A stop 32 carried by bar 26 engages the 0 under side of frame 18 and a spring 34. coiled about bar 26'yieldably urges guides 28 and bar 26 to the normal position where stop 32 is functioning. Guide finger 36 extends upwardly from frame 18 and terminates there-. above in a transverse plane intermediate movable guides 28. When the attachment is in actual use it is obvious that blade 10 is bedo not press down upon the hair to interfere with the cutting operation and their positioning beyond each end of blade 10 is a novel feature which contributes to the efficiency of the device.

As shown in Fig. 2, connecting bar 26 extends beneath the blade and plates of the razor and nothing interferes with the cutting action. The stabilizing guide member 36 contributes further toward a neat operation and the attachment greatly enlarges the possibilities of any safety razor.

Parts of the attachment proper are pref erably made of metal, but may be formed in any suitable fashion so long as the salient features herein are preserved in the structure.

It is understood that a large number of modifications might be practiced without departing from the spirit of the invention or scope of the appended claims.

hat is claimed as new and desired to be secured by Letters Patent is:

1. The combination with a safety. razor having a cutting blade interposed between an upper and a lower plate, of a hair trimming attachment including a pivotally mounted guide at each end respectively of said blade, the cutting edge of said blade moving between said guides as the attachment is operated.

2. The combination with a safety razor having a cutting blade interposed between an upper and a lower plate, of a hair trimming attachment including a pivotally mounted guide at each end respectively of said blade; a cam bearing face formed on each of said guides, the cutting edge of said blade being positioned between said guides, said cam faces being eccentric to said cutting edge whereby the same moves toward and from a line connecting said cam faces as the guides are moved about their pivotal mountings.

3. The combination with a safety razor having a cutting blade interposed between an upper and a lower plate, of a hair trimming attachment comprising a pivotally mounted guide at each end respectively of said blade and spaced therefrom; a cam bearing face formed on each of said guides; and means yieldably maintaining. said guides in predetermined position with respect to the cutting edge of said blade.

a. The combination with a safety razor having a cutting blade interposed between an upper and a lower plate, of a hair trimming attachment comprising a pivotally mounted guide at each end respectively of said'blade and spaced therefrom; a cam bearing face formed on each of said guides; and means yieldably maintaining said guides in predetermined position with respect to the cutting edge of said blade, said means including a connecting bar extendlng between said guides beneath said lower plate, a spring mounted upon said bar to impart yielding force thereto, and a movement limiting stop carried by said bar.

5. The combination with a safety razor having a cutting blade interposed between an upper and a lower plate, of a hair trimming attachment comprising a pivotally mounted guide extending transversely of said blade at each end thereof; a connecting bar joining said guides beneath said blade; a retrieving spring mounted upon said bar; and a movement limiting stop carried by said bar to limit rotary movement thereof.

6. As a new article of manufacture, a hair trimming guide for safety razors comprising a frame; a bearing at each end thereof; a connecting bar journaled in said bearings; a cam-shaped guide mounted upon said bar; and means yieldably maintaining said guides in predetermined position relative to said frame.

7. As a new article of manufacture, a hair trimming guide for safety razors comprising a frame; a longitudinal attaching slot formed in said frame; a movable guide at each end respectively of said frame; and a stationary guide finger terminating in spaced relation to said frame and between said movable guides.

8. As a new article of manufacture, a hair trimming guide for safety razors comprising a frame; an attaching slot formed by said frame; a rotatable guide at each end respectively of said frame, extending laterally from one side thereof; and a stationary guide finger projecting from'said frame at the oppo site side thereof and terminating in atrans verse plane intermediate said guides.

9. As a new article of manufacture, a hair trimming guide for safety razors comprising a frame; an attaching slot formed longitudinally of said frame; a depending bearing integral'with the said frame at each end respectively thereof; a connecting bar journaled in said'bearings for rotation; a guide having an arcuate bearing face mounted on said bar adjacent each of said bearings respectively; a spring coiled upon said bar intermediate said bearings; and a stationary guide finger integral with said frame.

In testimony whereof, I hereunto affix my signature.
