Patented Oct. 27, 1931 i rAuL H. L-EHMANN, or mem taxes AIR nx'rcaAc'roe AND TUBE nmmme 'rooIl Application filed July 28,
This invention relates to pneumatic tires and tubes and it has partlcular reference to devices for repairing automobile inner-tubes and the principal object of the invention resides in the provision of a simple and inexpensive tool of such character and design that it may be inserted into a hole or rupture in the inner-tube to serve a dual purpose, that of extricating air and for marking the puncture.
Another object of the invention resides in the addition of a novel instrument with which surplus air may be extracted from the innertube without the necessity of removing the valve core and cap for this purpose.
Still another object of the invention resides in its peculiar construction, affording means for roughing or buffing the area about the puncture in order to insure positive adherence of the puncturerepair patch and further, the invention is provided with means by which surplus cement may be scraped ofi', preparatory to the application of the patch.
- With the foregoing objects as paramount, the invention has particular reference to its peculiar construction and other objects which will become manifest as the description proceeds, taken in connection with the accompanying drawings wherein;
Figure 1 is a perspective view of a device constructed according to the'present invention.
Figure 2 illustrates a section of an innertube, showing the invention inserted in the puncture.
Figure 3 shows the invention applied in buffing the tube immediately about the puncture.
Figure 4 illustrates the invention applied in scraping off the surplus cement preparatorv to the application of the patch,.and
Figure 5 is an end elevational view of the invention as shown in Figure 1.
Continuing more in detail with the drawings, it is pointed out that the invention is shaped from a single piece of material, the peculiarly formed body affording theseveral I utilitarian features hereinbefore mentioned, namely, the hollow pointed handle l which is 1930; Serial No. 471,173.
insertable into the rupture or puncture in the tube to be repaired.
The handlel extends obliq uely from the body of the tool, the said body'being comprised of the flattened surface 2iwith upturned edges 3. It will be observed'that thesurface 2 is perforated at a.
These perforations are punched downward to afford a gratlng surface such as shown in Figure 5 and shown in use in Figure 3. This opera- 160 tion is necessary usually in the application v of what 1s generally known as cold patch in order that the cement used in such application will quickly take hold toth surface of the rubber.
It is usually recommended that a considerable amount of cement be applied to the tube and after having rubbed the same'into the roughened part, the superfluous cement 1s removed. To conveniently remove thissuperfluous cement the upturned edges 3 are provided with which cement is scraped .from the tube, as shown in Figure l, preparatory to the application of. a patch of the desired 7 size.
Considerable difliculty has'been heretofore encountered in extracting the air contained within the tube in order to produce a flat surfacefor theapplication of the patch. Usu- I ally, the valve cap and core are removed- 0 from the valve stem or perhaps a match or. other article is inserted into thevalve stem to hold the valve open to enable the air to escape.
I tion is particularlyuseful through the medi um of its pointed handle 1, for extracting the air from the tube.
It is simply necessary to e. smooth force the pointed end of the handle into the.
puncture in the manner shown in Figure 21;
and after the air has been extracted the operations hereinbefore described may be proceeded with.
Manifestly, the construct pable of considerable modification, and such modification as is considered withinthe scope and meaning of the appended clalm, 1s also considered with invention;
in the spirit and intentof th ion shown is cae What is claimed is:
As a new article of manufacture, a tube repairing device including a flat body having a series of perforations therein to provide an abrading surface, the side edges of said body being turned abruptly upward, a handle for said body being formed from the'material of which said body is composed and extending at an angle from said body, said handle being shaped into tubular form by turning the sides of the material inwardly whereby the handle will be gradually reduced in diameter and terminate in a point.
In testimony whereof I afiix my signature.
PAUL H. LEHMANN.
