Claims.

This invention relates to tools of the character employed by linoleum layers and has for its primary object, the provision of a device for spreading paste, cement, glue or the like, upon surfaces over which a covering is to be placed.

One of the important aims of this invention is to provide a paste spreader for linoleum layers,

the character of which insures an even distribu tion of the paste; presents an easily handled holder for a specially molded live rubber strip; and makes it possible to spread paste along the corners of a room presented by the meeting of the floor and walls thereof, without marring, scratching or otherwise injuring the woodwork on vertical wall surfaces.

This invention has for an even further object, the provision of a spreader of the aforementioned character, the grip whereof is formed of a relatively light yet stiff material and combined with a serrated resilient strip in such fashion as to permit effective manipulation and replacement.

Other objects of the invention will appear during the course of the following specification, referring to the accompanying drawing, wherein:

Figure l is a side elevational View of a paste spreader made to embody the present invention.

Fig. 2 is an end elevational view thereof.

Fig. 3 is a vertical cross sectional view taken on line III-III of Fig. l; and

Fig. 4 is an enlarged detailed fragmentary elevational view of a portion of the resilient strip, illustrating the form of notches created therein.

In producing a tool for spreading paste or the like, in accordance with the present invention, the U-shaped holder generally designated by the numeral 6, is made of an originally flat piece of metal that has been formed to produce inturned lips 8 along each end thereof and arcuate faces l9 along the longitudinal edges thereof. When the originally fiat strip of material, such as aluminum is rebent upon itself, about a mandrel or other suitable instrument to produce grip [2, legs 14 are created to embrace strip l6. These legs l4 are in spaced relation throughout their areas and grip l2 projects laterally to each side of the outer faces of legs i4.

Strip I6 is made of live rubber and formed to present a number of small notches 18 extending inwardly from the free edge thereof. These notches may be molded but their size is such as to render molding inefiective for desirable results. It has been found therefore, that the use of hot wires is preferable, for notches 18 should be relatively shallow and narrow to insure the production of minute ridges along the face of the paste being spread.

The length of strip I6 is greater than the length of lips 8 and the legs I4 of holder 5. The projected portions 20 of strip I6 create buffers at each endof the spreader for engaging the vertical surfaces 22 of a wall.

Strip I6 is secured in place between legs M by bolts or analogous means 24 and inturned lips 8 grip strip l6, as shown in Figs. 2 and 3. If live rubber is not employed in making strip 16, results will not be satisfactory and a breaking Will occur along lips 8 after the spreader has been in use a short time.

The extended ends 29 of strip [6 are arched as at 26 to lend flexibility to buffers 20 and further, to permit that portion of the spreader to be introduced into cavities below the conventional type molding or quarter-round when linoleum or floor covering is being layed thereunder. With such form, the edges of grip 6 will not come into contact with the molding to mar or scratch the same.

Legs M are in spaced relation as aforesaid to permit cleaning the tool when desired. No cavities or openings capable of catching and holding paste are present in this tool when formed as illustrated and described, and washing is quickly accomplished when grip I2 is hollow and legs I4 are spaced apart.

In practice, pressure upon the holder will increase or decrease the effective depth of serrations or notches l8 and a greater or lesser amount of paste may be spread to suit conditions and the desires of the operator.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. A spreader of the character described comprising a resilient strip having a serrated edge; a U-shaped holder, formed of stifi material rebent upon itself along a medial transverse line, for the strip; and means for clamping the strip between the free edges of the legs of said holder with the serrated edge thereof projecting beyond the confinesof said holder.

2. A spreader of'the character described comprising a resilient strip having a serrated edge; a U-shaped holder, formed of stiff material rebent upon itself along a medial transverse line, for the strip; and means for clamping the strip between the free edges of the legs of said holder with the serrated edge thereof projecting beyond the confines of said holder, said holder having a grip formed along the bight thereof, said grip extending laterally to each side of the holder.

3. A spreader of the character described comprising a resilient strip having a serrated edge; a U-shaped holder, formed of stiff material rebent upon itself along a medial transverse line, for the strip; and means for clamping the strip between the free edges of the legs of said holder with the serrated edge thereof projecting beyond the confines of said holder, said resilient strip having a portion thereof extending beyond the holder along three sides thereof.

4. A spreader of the character described comprising a U-shaped holder formed of sheet metal rebent upon itself along a medial transverse line, said holder having opposed legs, and a grip at the bight thereof; a strip of resilient material, provided with serrations along one longitudinal edge, between the free marginal edges of the legs; and means for clamping the strip between the legs of the holder with the serrated edge thereof projecting beyond the confines of said holder, the ends of said strip being extended beyond the ends of the holder to form buffers, said holder progressively decreasing in length as the grip is approached from the free marginal edges of the legs.

5. A spreader of the character described comprising a U-shaped holder formed of sheet metal rebent upon itself along a medial transverse line, said holder having a grip at the bight thereof, and opposed legs, the free marginal edges of the legs being inturned to form lips; a strip of resilient material between the free marginal edges of the legs; and means for clamping the strip between the legs of the holder with the free longitudinal edge thereof projecting beyond the confines of the holder, whereby the said lips form indentations at their point of contact with the resilient strip.
