stances, such as metallic or other particles that become lodged in theeyes.
Further objects of the inventionare .to' provide, in a manner as hereinafter set forth, a removing device for the purpose set forth, which is simple in its construction and arrangement, strong, durable, compact, thoroughly eflicient and convenient in its use, and inexpensive to manufacture.
With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an elevation of a removing device, in accordance with this invention, with the cap removed.
- Figure 2 is an elevation of the device with the shifting elementand clamping sleeve for the latter removed.
Figure 3 is a vertical sectional View of the clamping sleeve.
Figure 4 is a top plan view of the device with the shifting element removed.
Figure 5 is a fragmentary view, in elevation, illustrating the protecting cap in position.
A removing device, in accordance with this invention, comp-rises a particle shifting element, a particle removing element of the attraction type, clamping means for the shifting element, a handle member, and a protecting cap. The removing element is formed of magnetized metallic material, preferably steel, to provide a magnet capable of loosening and removing foreign substances which become lodged in the eyes. The shifting element is formed from a flexible strand, preferably hair.
The handle member is indicated at 1 and may be of any suitable construction, preferably as shown, and which has secured to the, outer end thereof, in any suitable manner, the removing'elen 'ent referred to gen eral ly'by tl1e reference character 2, formed from a-length of magnetized metallic material and consisting of a'base 3 having pro jecting therefrom four arms iqpf equal length and each of which is quadrant-shaped in cross-section. Eachlof the arms a, in proximity to its outer end, is provided with peripheral threads 5, and thethreads 5'of one arm are sodispos'ed to provide a continuation of the threads 5 of an adjacent arm. The outer end of each of the arms 4 is rounded, as at 6, so that when the arms are secured in abutting engagement, through i a means to be presently referred to, the outer end of the element 2 will be semispherical in contour. The arms 4, in connection with a clamping sleeve to be presently referred to, form a clamp for fixedly 7 securing the shifting element in loop-like form. Normally the arms 4: are spaced from each other to provide passages 7 disposed at right angles with respect to each other, and two of said registering passages are adapted to receive the shifting element when the latter is arranged in loop-like form, as shown in Figure 1.
The shifting element is indicated at 8 and is of a length whereby loops 9 of varying lengths may be formed and extended from the end 6 of the element 2.
The removing element 8 is clamped between a pair of arms 4 by a sleeve 10 provided on its inner face with threads 11, which terminate at a point removed from the upper end of said inner face. That portion of the inner face of the sleeve 10, which is not provided 'With 'the' threads ?1 1, is smooth and curved, as at 12, so as to snugly fit the outer end of the element 2, and further to provide for a portion of the outer end of the element 2 to project therefrom, as shown'in Figure 1. A protecting cap 13 is provided for the element 2 when the del vice is not used.
When using the device the cap 13 is removed and if it is not desired to shift the particle in the eye through the medium of the element 8-, the said elementis not coni 7 ill) from the element 2 and the latter canbe employed to attract and remove the metallic particle. 'In, some instances the element 8 can be employed to remove'particles lodged in the eyes. The sleeve 10 engages with the threads 5 of the arms 4.
It is thought that the many advantages of a removing device, in accordance wlth this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it fis'to be understood that changesin the details of construction can be had which will fall Within the scope of the invention as claimed.
What we claim is A removing device for the purpose set attraction element provided with peripheral screw threads intermediate its ends, an adjustable flexible shifting element of loop-like form extending within and projecting from the outer.end and sides of said slitted portion, and means engagin with said threads i for clamping lengths 0 said shifting element Within'said slitted portion.
In testimony whereof, we aflix our signa-- tures hereto.
