Filed May 29, 1958, S81- NO. 738,757 7 2 Claims. (Cl. 30-348) The present invention relates to razor blade adapters for razors, and particularly to such a device formed for shaving above and around the ears.
The primary object of the invention is to provide a razor blade which has an extent suificient to permit ease of shaving the-hairline above and around the ears.
Another object of the invention is to'provide a razor blade adapter unit of the class described above in which the blade extends beyond the normal blade line and is supported to prevent undue flexing.
A further object of the invention is to provide a razor blade adapter unit of the class described above in which 14 extending oppositely of the threaded boss' 11 andthe} base plate 12 has a slot (not shown) to receive the guide:
bar 14. g The razor-blade adapter unit A includes a razor blade 15 which is of'generally rectangularfform and has the opposite side edges thereofcut out at 16; 17,' respectively,
as best seen in Figure 4. An elongated slot 18 is formed in the blade 15 parallel to the rear edge 19 thereof to engage over the elongated guide bar 14. The slot 18 is enlarged centrally at 20 to engage over the threaded boss 11 of the head 10. The blade 15 has a pair. of oppositely disposed bores 21', for reason tobe assigned.
Oppositely of the rear edge 19 of the blade 15 there extends a forward edge 22 having a large central cut-.
ting portions thereof concavely curved as at 23 to engage about the ears of the user when shaving the hairline overlying the. ears.
A generally rectangular base plate 24 is provided with an elongated slot ZSadjacent the rear edge 26 thereof and having an enlarged central portion 27 to engage over the guide bar 14 and threaded boss 11 respectively. The base the blade has an arcuate cutting edge to fit and trim around the ears.
A still further object of the invention is to provide a razor blade adapter unit of the class described above in which the razor blade is provided with an overlying and an underlying support fixedly secured thereto.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which: I

Figure 11 is an exploded perspective view of the device illustrated in Figure 10.
Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference character A indicates generally a razor blade adapter unit constructed in accordance with the invention.
The razor blade adapted unit A, as illustrated in Figures 1 through 5, is utilized with aconventional razor generally indicated at R and having a head 10 carrying a centrally positioned threaded boss 11 integrally thereon. A base plate 12 is engaged over the threaded boss 11 and a hollow handle 13 is threaded onto the threaded boss 11 to clamp the base plate 12 against the head 10.
The head 10 is provided with an elongated guide bar plate 24 has a pair of upstanding semi-spherical guide bosses 28 arranged to engage in the bores 21 to hold the blade 15 with the slot 18in alignment with the slot 25 of the base plate 24.
Oppositely of the rear edge 26, the base plate-24 is concavely curved at 29 and provided with a depending.
flange 30 to transversely reinforce the base plate 24. The flange 30 terminates slightly beyondthe cutting edge 23 so that the razor blade 15 will be guided thereby during shaving.
' A- generally rectangular top plate 31 is provided with a slot 32 extending parallel to the rear edge 33 thereof and the slot 32 has an enlarged central portion 34 to engage over the threaded boss 11. The top plate 31 has a forward' edge 35 concavely recessed at 36 to support the blade 15 from above. 7 The base plate 24, razor blade 15,. and the plate 31 are welded or otherwise fixedly secured.
together to form an integral unit for insertion in the razor R.
In Figures 6 and 7, a razor blade adapter unit B is illustrated wherein a generally rectangular razor blade 15b is provided with a slot 18b extending parallel to the rear edge 19b thereof. The slot 18b is enlarged as at 20b and functions the same as the slot 18 and enlargement 20 of the preferred form of the invention. The razor blade 15b is provided with a pair of spaced bores 21b, for reasons to be assigned. The razor blade 15b oppositely of the rear edge 1% thereof is provided with an elongated straight cutting edge 22b, as best seen in Figure 7.
A base plate 24b is constructed identical to that of the base plate 24 including the semi-spherical guide bosses 28b but having the flange 30b at the edge thereof opposite the rear edge 26b extending straight across the base plate 24b to correspond to the cutting edge 22b of the blade 15b.
A generally rectangular top plate 31b has an elongated slot 32b extending parallel to the rear edge 33b thereof and having an enlarged central portion 34b all identical to the top plate 31. The forward edge 35b of the top plate 31b extends straight across the blade 15b In Figures 8 and 9, another modified form of the V invention comprising an adapter unit C is shown to have a razor blade formed generally rectangular and sub stantially shorter than the razor blade 15. The razor blade 15c has a pair of spaced apart guide bores 21c positioned quite close to the rear edge 19c but spaced inwardly from the concave cutting edge 23c. A base plate 24c identical to the base plate 24 supports the razor blade 15c, and a top plate 31c identical to the top plate 31 engages over the razor blade 150. The top plate 31c, base plate 240, and razor blade 150 are welded or otherwise fixedly secured together with the cutting edge 23c projecting sufliciently to permit shaving therewith.
In Figures 10 and 11, a razor blade adapter unit D isillustrated as another modified form of the invention and consists of a generally rectangular razor blade d having an elongated slot 18d formed adjacent to and parallel with the rear edge 19d thereof. The slot 18d has an enlarged central portion 20d and the blade 15d has a pair of spaced apart bores 21d, for reasons to be assigned.
A forward edge 22d is arranged oppositely of the rear edge 19d and has a central concave cutting portion 23d similar to the concave portion 23 of the blade 15. A base plate 24d is formed with a pair of semi-spherical bosses 28d arranged in spaced apart relation thereon closely adjacent to the rear edge 26d thereof. The base plate 24d oppositely of the rear edge 26d thereof has a centrally concave forward edge 29d with a depending flange 30d integrally arranged thereon.
A generally rectangular top plate 31d is somewhat shorter than the top plate 31 and has a rear edge 33d extending straight thereacross. The top plate 31d has a forward edge 35d which is centrally recessed at 36d.
The razor blade 15d, base plate 24d, and top plate 31d are welded or otherwise fixedly secured together as a unit with the semi-spherical bosses 28d extending through the bores 21d and with the slot 18d of the blade 15d exposed for engagement with the guide bar 14 and threaded boss 11 to secure the razor blade adapter unit D to the razor R.
It should be understood that each of the razor blade adapter units A, B, C, and D can be utilized in conventional razor structures R.
It should be understood that while a pair of guide bosses cooperating with a pair of bores has been indicated in each form of the invention, either more or less of these elements may be employed.
Having thus described the preferred embodiments of the invention, it should be understood that numerous structural modifications and adaptations in addition to those illustrated may be resorted to without departing from the scope of the appended claims.
What is claimed is:
1. A razor blade assembly comprising a top plate having a slot therein and a concaved forward edge, a blade having a slot therein aligned with said first mentioned slot, and having a concaved cutting edge aligned with said first mentioned concaved edge and a bottom plate having a slot therein aligned with said first and second mentioned slots, and a concaved forward edge aligned with said concaved cutting edge, said bottom plate having a depending flange along said forward edge, said top plate, said blade plate and said bottom plate being integrally fixed together as a unit.
2. The structure of claim 1 wherein openings are provided in said blade plate, and detent means are provided on said bottom plate engaging in said opening for proper alignment of said concaved cutting edge.
