Y 1 1 I t r I SPECIFICATION forming part of Letters IPatent No. 605,330, dated June '7', 1898.

Application filed November 11, 1897. Serial No. 658,165. (No model.)

.To all whom it puny concern:

Be it known that I, PHILO NEWELL, a citizen of the United States, residing at Oakville, in the county of Litchfield and State of Con- 5 necticut,havc invented certain newand useful Improvements in Devices for Repairing Pneuinatic Tires; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable oth- IO ers skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a device of thischaracter which may be readily carried in a pocket in a mans or womans clothing or in a tool-bag and which will re pair any ordinary puncture in a bicycle-tire and will carrya sufficient number of plugs to repair a number. of punctures.

lVith this end in view I have devised the novel plug and means for carrying and inserting such plug which I will now describe, and then specifically point out in the claims.

In the accompanying drawings, forming part of thisspecification, the tool,wl1ich also comprises a magazine,and the plugsare shown on an enlarged scale.

Figure 1 is a longitudinal section of the two shells connected to the double-threaded hub, which is shown in elevation, the magazine containing a number of plugs,which are also shown in elevation; Fig. 2, an elevation of the device complete, showing the manner in which a puncture may be'enlarged by the circular cutter, a bicycle-tire being shown in section; Fig. 3, a similar view showing the manner in which the inner head and shank of a plug are placed in position in a puncture;

Fig. 4, a similar View showing the manner in" shell having at one end prongs 3, which are adapted to engage the outerhead of theplug, as will be more fully explained, and at the other end an internal thread 2, similar to the thread on shell A. Shell B serves as a maga- Inal threads'2 upon the shells.

which is threaded, as at 6, for a purpose presently to be explained. In the assembled position thread 2 upon shell A engages the thread on the end of, hub D,which carries the stem,the stem lying within the shell, as clearly shown in Fig. 1, and thread 2 upon shell B engages the thread upon the other end of hub ;D,'this shell serving as a magazine in which a number of plugs may be carried.

l -The construction of my novel plug will be clearly understood from Figs. 3 and 4 in conthe shank of a plug.

nection with Fig. 1. Each plug comprises a flattened inner head 7, which has formed integral therewith a central shank 8, which is internally and externally threaded.

9 denotes the outer head,which'is also flattened and is preferably rounded upon its 7 5 outer face and is provided with a central threaded opening 10 and upon its outer face with recesses 11,which are adapted to receive prongs 3 upon shell B.

The operation of repairing a puncture is as follows: The puncture may be enlarged, if necessary, by means of the cutter, as clearly shownin Fig 2. Shell B is removed from the hub and a plug taken out, after which the shell is replaced upon the hub, as clearly shown in Fig. 3. Shell A is removed from, the hub, and outer head 9 is removed from The outer head of the plug is then passed over stem 5, recesses v11 being toward the hub, as clearly shown in Fig. 3, in which said inner head is indicated in full lines at a raised position, it being un derstood, of course, that in use saidouter head would be held at the raised position by the hand of the user.

is then engaged with the internal thread in shank S and the inner head 7 is passed through the puncture or opening in the tire, which I have indicated by 12, by means of the stem, to which it is rigidly secured by the engage- I00 Thread 6 upon the stem i ment of thread 6 with the internal thread in shank 8.

It will of course be understood that when a tire has been punctured it may be pinched together, so as to place the opening in most convenient shape to receive the inner head. I find in practice that after using the cutter, as in Fig. 2, inner head 7 may be readily passed through the opening by means of the stem. Having placed the inner head of the plug within thetire, as in Fig. 3, the operator, still holding the inner head by means of the stem, retains the shank in the opening, draws the inner head against the inner side of the tire, and with the fingers turns the'outer head'down to place upon the shank, as shown in dotted lines in Fig. 3. Having turned the outer head down as far as possible by hand, the operator removes the stem from the shank, and by means of prongs 3 upon shell 13, which are placed in engagement with recesses 11, turns outer head 9 down closely upon the outer face of the tire, so that the tire will be clamped tightly between the inner and outer heads of the plug, the shank filling the opening in the tire, which may be the puncture itself or may be formed by the use of the cutter, as in Fig. 2.

Having thus described my invention, I claim 1. A device for repairing pneumatic tires comprising a hub threaded at each end and having at one end a stem threaded at its outer end, and a shell adapted to engage the other end of the hub and to serve as a magazine, substantially as shown, for the purpose specified.

2. A device for repairing pneumatic tires comprising a hub threaded at each end and having at one end a stem threaded at its outer end, a shell adapted to engage the hub and inclose the stem, and a shell adapted to engage the other end of the hub and to serve as a magazine, substantially as shown, for the purpose specified.

3. A device for repairing pneumatic tires comprising a hub having a circular rib and threaded at each end and having at one end a stem threaded at its outer end, a shell adapted to engage the hub and inclose the stem and having at its outer end a cutter and a shell adapted to engage the other end of the hub and to serve as a magazine substantially as shown, for the purpose specified.

4. A device for repairing pneumatic tires comprising a hub threaded at each end and having at one end a stem threaded to engage the shank of the plug, a shell adapted to engage the hub and inclose the stem and a shell adapted to engage the other end of the hub and to serve as a magazine for plugs and having at its outer end prongs adapted to engage the outer head of the plug.

5. The plug C comprising an inner head having a shank formed integral therewith and threaded internally and externally and an outer head threaded to engage the exter nal thread upon the shank.

6. A device for repairing pneumatic tires comprising a hub threaded at each end and having at one end a threaded stem, a shell adapted to engage the other end of the hub and serve as a magazine for plugs and having at its outer end prongs and a plug consisting of an inner head and a shank internally threaded to engage the stem and externally threaded to engage an outer head which is itself adapted to be engaged by the prongs.

In testimony whereof I affix my signature in presence of two witnesses.

PI-IILO N EWELL.
