M. DE LARBER PUTTY REMOVING TOOL Filed May 21, 1962 3,091,852. PUTTY REMOVIG TOOL Mathew De Larber, 1924 Pestalozzi St., St. Louis 18, Mo. Filed May 21, 1962, Ser. No. 196,205 1o Claims. (el. 30-172) This invention relates to hand tools and more particularly to a hand tool for removing hardened putty from Window panes and sashes.

Among the several objects of this invention may be noted the provision of a putty removing tool which is adapted eioiently and easily to remove hardened putty from window panes and sashes; the provision :of a putty removing tool of the class described which reduces the danger of scraping the hands against the Window sash and the possibility of receiving splinters or abrasions from the window sash; and the provision of a putty removing tool such as described Iwhich is simple and economical in construction. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope tof the invention being indicated in the following claims.

In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,

FIG. 1 is a plan view of the tool as applied against a window, the broken lines illustrating appropriate positions of an operators hands;

FIG. 2 is a right side elevation of the tool shown in FIG. l; and

IFIG. 3 is a section taken on line 3-3 of FIG. 1.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.

In the use of prior putty removing Scrapers or knives it is not uncommon for the users hands to receive abrasions or splinters from the sash. This is due in part to the force which must be :applied to the putty knife in order to remove the hardened putty. If the putty knife slips when the user is applying this force, his hands may strike or scrape the window sash, thereby receiving abrasions or splinters. By means of the present putty removing .tool the hardened putty is not only more completely removed by the application of substantially less force than formerly required, but the danger of obtaining abrasions or splinters is substantially eliminated.

Referring now to the drawings, the putty removing tool is generally indicated at 1. The tool 1 may be formed from steel for example, and has two more or less parallel arms or bars 3 and 5 joined -at their inner ends by an offsetting portion or web 7 extending generally transversely to the arms. The arms 3 and 5 and web 7 are of a generally rectangular configuration in cross section. The arms 3 yand 5 are thus offset from one another by .the web 7 and extend in opposite directions from the web.

Arm 3 is beveled or slanted to a point on its outer end as indicated at 9. The pane engaging surface of arm 3 is indicated at 11 and -is substantially at. A plurality of curved scraping ribs or teeth 13 extend outwardly from the sides 15 and 17 of arm 3. These ribs have substantially coplanar knife-like edges :and are curved so that the upper end of each rib is further from web 7 than the lower end of the respective rib. The planes of the outer edges of the ribs extend substantially perpendicular to surface 11. The purpose of the configuration of these n'bs will become apparent as hereinafter described. An elongate recess or depression 19 is provided in the outer surface 21 for receiving pressure from a thumb as will become apparent.

The outer end of arm is notched as indicated at 23 3,091,852 Patented June 4, 1963 rto provide two ears 25 and 27. The ears and notch may be utilized as a nail puller. 'Ihe beveled end 9 of arm 3 may be used :as a chisel, for example.

The tool is shown in FIG. 1 as being applied to a Window pane W and sash S. A triangular iillet of hardened putty is indicated at P, which is to be removed. To use the tool 1 for removing putty P in FIG. 1, the arm 5 is grasped by the left hand LH. The surface 11 of arm 3 is placed against the window W and the ribs 13 on the side 15 of arm 3 are pushed laterally against the putty. Right hand thumb RT is placed in the depression 19 and biasing pressure is applied toward the putty by the thumb. The tool is then pulled downwardly as viewed in FIG. 1. The ribs 13 on side 15 scrape and plow the putty out from the window glass 4and sash joint as the tool is pulled downwardly. The ribs also engage and tear or pull out the glaziers points, if any, from the sash S. The putty, as it is scraped from the window and sash, rides or is plowed outwardly bet-Ween the ribs 13. It will he `noted that the lower end portion of each rib digs into the putty at an :angle with respect to the direction of pull which is less than the angle of the upper end portion of the respective rib relative to the direction of pull for effectively plowing the putty out between the ribs. Upon reaching the surface 21, the putty is in a crumbled condition and falls away. The tool may be pulled falong the joint of the window and sash several times if desired to scrape all of the putty from the sash, thereby leaving a clean generally at surface substantially perpendicular to the window against which new putty may be applied. -By reciprocating the tool in the FIG. l position, the chisel point 9 will serve also to clean the glass of putty adjacent to sash S. It will be understood that the positions of fthe hands are changed in removing putty from the other sides of the window.

Accidental slippage of the tool is unlikely since the plurality of ribs dig into the hardened putty. However, should a slip occur, it is unlikely that the hand will come in contact with the sash, since the vleft hand LH, which is grasping arm 5, is located above the sash S.

It will be understood that in some cases less tenacious putty can be removed by using one hand :only on the arm 5, the use of a thumb in recess `19 being unnecessary.

AIn view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the labove construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the -accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
