Sept. 29, 1959 F. R. FERREIRA SQUEEGEE HOLDING CLAMP Filed Sept. 9. 1953 FIE E IN V EN TOR. FRED R FERPE/PA ATTORNEYS United States Patent SQUEEGEE HOLDING CLAMP Fred R. Ferreira, San Leandro, Calif., assignor to Morse- Starrett Products Company, Oakland, Calif., a corporation of California Application September 9, 1953, Serial No. 379,138

3 Claims. (Cl. 15-245) blade member within its supporting metal channel adjacent the ends of the channel. After squeegees having the rubber blades fastened in this manner were used a while, the rubber blade would tend to buckle at some point between the point at which it was fastened due to relaxing and elongation of the rubber blade.

It is the principal object of the present invention to provide a novel form of holding the rubber squeegee blade with relation to the channel brass member in which it is mounted wherein the rubber is held only at its central portion and is free at the ends, permitting it to extend and assume a straight line position without buckling.

Various other objects of the invention will become apparent in reading the following detailed specification in conjunction with the drawing wherein:

Fig. 1 is a plan view of a squeegee embodying principles of my invention, and showing a novel form of clip member engaging the squeegee blade.

Fig. 2 is a sectional view taken on lines 2--2 of Fig. 1.

Fig. 3 is a plan view of the novel clip member.

Fig. 4 is an end view of said clip member showing the teeth on the forward end thereof.

Fig. 5 is a side view of the clip shown in Figs. 3 and 4.

The squeegee consists primarily of a tapered cylindrical handle member adapted to receive therewithin a wooden handle. The forward end of said cylindrical handle is opened up to form a flat triangular shaped portion 2. Adjacent the forward end of the triangular shaped portion 2, there is located a transversely extending rib or indentation 3 in the surface of the sheet metal material, usually brass, of which the handle member is composed. The purpose of this depression or rib 3 will become apparent in conjunction with structure which Will be described later. Adjacent the depression 3 there are provided two holes 4 through which bolts are adapted to extend for securing together the handle member and a clip member to be described.

The squeegeeing portion of the device consists primarily of an elongated brass channel member generally indicated at 5 having an enlarged portion 6 at the lower end thereof and an upstanding flange portion 7 on one side and a longer flange portion 8 at the opposite side, the flange 8 being turned slightly outward with respect to the center line of the channel. Within the brass channel member is a rubber squeegee element 9 having ad jacent its inner end an enlarged portion 10 which is slidably received within the enlarged portion 6 of the brass channel member 5. The manner in which the rubber squeegee element 9 is retained within the brass channel member will be described later.

Cooperating with the handle member in order to re tain the rubber squeegee element in its proper relationship to the handle there is provided a clip member 11 generally triangular .in shape and having a transverse depression or rib 12 formed in the surface thereof adjacent one of its sides. This rib 12 is complementary to and adapted to cooperate with the rib 3 on the handle portion of the device. The forward edge of the clip member, the edge adjacent and parallel to the rib 12, is turned inwardly and is formed with a plurality of teeth 13. The end of the clip member opposite from the teeth 13 is bent downwardly as shown at 14. When the clip member is properly assembled with relation to the handle member, the portion 14 lies in the open portion 15 of the handle 1 and bears against the portion 2 of the handle member.

The device is assembled in the following manner: As best shown in Fig. 2, the rubber squeegee element 9 is slid longitudinally into the brass channel member 5. The brass channel member is then placed in the rib 3 on the handle surface 2 with the short side of the channel facing outwardly, and the clip member 11 is placed with the rib 12 adjacent the short side of the channel member. The bolts 18 are then inserted through the holes 4 in the handle member and the complementary holes 17 in the clip member and are fastened therein by means of the nuts 19. When so assembled, the rib portions 3 and 12 cooperate to grip the channel 5 and retain the channel in position with respect to the handle member. Similarly, the teeth 13 on the forward edge of the clip member 11 extending beyond the short flange 7 of the channel member 5 are forced into engagement with the rubber squeegee element 9, biting therein to retain said element 9 in position with respect to the channel member 5 and with the handle member 1.

From the foregoing specification it is evident that I have provided a novel means whereby the squeegee element is held at its central portion with its ends free to assume a straight line position within the channel regardless of changes in its length.

While I have shown and described the preferred form of my invention, it is to be understood that other forms of the invention are within the concepts disclosed herein, and that the invention is not to be limited to the specific form shown herein but rather is to be limited only by the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In combination, a handle member having a flat triangular shaped portion, a substantially U-shaped rigid channel member having walls defining an enlarged portion providing an elongated groove and a contracted portion defining a relatively reduced slot, a rubber squeegee blade having an enlarged portion received in said enlarged portion of the channel and a reduced portion projecting through said slot, a substantially triangular shaped clip member, an arcuate groove formed in the triangular shaped portion of said handle adjacent one edge thereof, a complemental arcuate groove formed in said triangular clip adjacent one edge thereof, means for fastening said clip to said handle portion with said arcuate grooves in opposed relation and containing therebetween the enlarged portion of said channel member, teeth on the edge of said clip member adjacent the arcuate groove thereof, said teeth extending at substantially right angles to the surface of said clip member beyond one of said walls of said U-shaped holder and biting into the rubber blade, said clip having a reduced edge opposite to said one edge turned inwardly toward elongated groove and a contracted portion defining a relatively reduced slot, a rubber squeegee blade having an enlarged portion received in said enlarged portion of the channel and a reduced portion projecting through said slot, a clip member, an arcuate groove formed in the flat portion of said handle adjacent one edge thereof, a complemental arcuate groove formed in said clip member adjacent .one edge thereof, means for fastening said clip member to said flat handle portion with said arcuate grooves in opposed relation and containing therebetween the enlarged portion of said channel member, means on the edge of said clip member adjacent the arcuate groove thereof, said means extending laterally trom said clip member and biting into the rubber blade, said clip memher having its edge opposite to said one edge turned inwardly toward and engaging said flat handle portion.

3. A device as set forth in claim 2 wherein said means on the edge of said clip member adjacent the arcuate groove thereof comprises a plurality of teeth extending laterally from said clip. member and biting into said blade.
