GUARD FOR HAIR GLIPPERS.

appncanon fusa November 7, .1925. seriai No. 671,597.

'lliis invention relates to improvements in guards for hair clippers, and has particular reference to the provision of means for protecting the teeth of a hair clipper against damage while the instrument is out of use.

An important object of the invention is to provide a hair clipper guard which may be readily attached to or detached from a hair clipper to prolect the teeth thereof, and having nevel ineans for retaining it upon the ciipper.

Another object is to provid-e such a device which will interlock with the plates of the clipper to prevent its accidental displacenient while in use.

@ther objects and advantages will be apparent from the following description, taken in connection with the accompanying drawings, wherein a preferred form of the invention is illustrated.

In the drawings, Fig. 1 is a side elevation of a hair clipper with my improved guard applied thereto.

Fig. 2 is a 'fragmentary top plan View thereof, on an enlarged scale, and illustrating how the guard is locked upon the clipper.

Fig. 3 is a similar view illustrating the necessary movement of the upper clipper plate to facilitate application and removal of the guard.

Fig. e is a detail perspective view of the guard per se.

Referring now to the drawings in detail, the reference character designates generally a hair clipper of any ordinary or preferred forni, and comprising essentially a lower stationary plate 11, and an upper movable plate 12. Each of the plates 11 and 12 has its front edge serrated to forin teeth 13 and 11 respectively, which cooperate to cut hair coming between them when the plate 12 is reciprocated. The plates 11 and 12 are heldA in close surface engagement by a spring (not shown) contained within a housing 15 which is rigidly mounted on the stationary plate 11, and a handle member 16, having a thumb piece 1T, extends from the housing 15. In order to reciprocate the upper plate 12 of the clipper, a lever 18 is provided, pivoted on the stud 19, as is well known to those skilled in the art; and the plate 12 is guided iii its reciprocation by means of slots 20 and 21 in which are disposed posts 22 mounted on the stationary plate 11. The parts of the clipper normally occupy a position of ln order to protect the 'teeth 18 and of the clipper from being damaged while the instrument is not in use, l provide a guard which comprises a body portion or plate 24, having an upwardly tapering por-V tion :.5 adjacent its front edge, and bent upon itself to form an overhanging lip 26 divergiiig from the tapering portion 25. The plate 2l is adapted to be positioned close up under the lower plate 11 of the clippers, and the teeth 13 and 121 are disposed between the tapering portion and the overhanging lip 26. Edge-guiding means are provided, preferably in the form of

flanges

27 and 28 extending upwardly from the plate 211 and adapted to engage the side edges of the lower clipper plate 11 to prevent lateral displacenient of the guard. integrally formed with the

flanges

27 and 28, adjacent the rear end thereof, are a pair of inwardly extending

ears

29 and 30 which overlie the clipper plate 11 to prevent the guard from dropping downwardly, and the front edge V31 of the ear 29 is squared for engagementk with the rear edge 32 of the upper clipper plate 12. The width of the ear 29 is great-er than the distance between the adjacent side edges of the plates 11 and 12, as clearly shown in Fig.

2, and by virtue of this fact the guard may be securely locked in place, and held against accident al displacement in any direction.

l/Vhen it is desired to apply the guard to a pair of clippers, the lever 18 is operated' against the handle 16 to slide the upper nievable plate 12 transversely on the lower plate 11 to a position as shown in Fig. 3, whereupon the plate 211 and associated parts of the guard may lbe slipped into place. rlhe lever 18 may then. be released and the guard will be locked in position. To remove the guard, the lever 18 is similarly operated to disen.u gage the edge 32 of the plate 12 from the front edge 31 of ear 29, permitting the device to be slipped olf the clipper.

From the foregoing it will be evident that I have provided a hair clipper guard, of simple construction, particularly adapted for use in protecting the teeth of the clipper while being shipped or transported, or in other conditions while not being used. Ob vionsly, the invention susceptible of inodilication, and the right is herein reserved to malte such changes as fall Within the scope of the appended claims, without departing from the spirit oi the invention. p

`What I claim as my invention and desire to secure by Letters Patent is:

1. A hair clipper guard, comprising a plate provided with means on its front edge or guarding the teeth of a hair'elipper, edge-guarding means extending transversely of the guarding means, and a locking member overlying a port-ion of the lower clipperl plate and abutting the rear edge of the upper clipper plate when the latter is in its extreme positionot rest, said guard being capable of sliding movement in the direction 0i' said edge-guiding means when the upper clipper plate is moved to an intermediate position.

2. In combination with a hair clipper, a guard plate provided with guarding means engaging over the clipper teeth, edge-means projecting from the plate transversely of the guarding means and engaging the side edges inane/a1 of the lower cutter plate, and substantially parallel, guiding means on the guard plate, overlapping the side edges oi said lower cutter plate adjacent to the back portion thereof, and retaining the guard on the clipper, by virtue of the abutment of one of the guidingmeans with the rear edge of the upper clipper plate when in its extreme position of rest, and being capable of disengagement by partial movement of the upper clipper plate.

B. ln combination with a hair clipper, a plate having guarding means on its front edge Jfor receiving and protecting the clipper teeth, iangee extending from the plate in a direction transverse to the guarding means, said iianges engaging the side edges of the lower cutter plate, and inwardly extending ears integral with the flanges and overlying portions of the lower cutter plate, one of said ears engaging the upper cutter plate to maintain the guard in position on the clipper.

In testimony whereot'l aiiix my signature.
