REPAIRING DEVICE.

Application filed February 12, 1926.l Serial No. 87,737. I

My invention relates to a repairing device, designed especially .for use in" applying patches on the inner tubes of pneumatic tires, and my invention has for its main object the provision of a novel tool of this character which will be simplein construction7 economical in manufacture, and highly efficient in use and which in addition may be conveniently employed in repairing all sizes of conventional tubes.

Another object of my invention is to provide a repairing tool of this kind which is characterized by having. means forstretching the tube, where it is to be repaired, vequally in all vdirectio-nsw Another object is to provide a tool in which the pressure for seatingv the patch. willl be exerted evenly thereon and in which the desired pressure may be exerted on the patch without danger of breaking'either the operating tool or the 2- or heat unit vulcanizing patches.

' tube being operated upon. Still a further object is to pro-vide a device that may be employed with equal facility and convenience in applying either wet cement patches Other objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings Vforming a part of this specification, and in .which,

l Fig. 1 represents a side elevational view of a repairing device made in accordance with the present invention, the device being shown as it appears when lholding the tube and when pressing a wet cement patch upon the tube; y

Fig. 3` represents a top plan View of the parts "shown in Fig. 1;

Fig. 4 is a longitudinalsectional view laken substantially on the line 4-21 of Fig. 5 is a sectional detail showing the presser shoe placed upon a heat Aunit vulcanizing patch to beapplied to the tube;

Fig. 6 is a top plan .view taken substantially on the line 6-6 of Fig. 5;

Fig. 7 is a vertical sectional view taken substantiallyon the line 7--7 of Fig. 4; and,

Fig. 8 is a vertical sectional view taken substantially on the line 8-8 of Fig. 4.

In the illustrative embodiment shown1 in the accompanying dra-wings, 9 designates vin general a base body having a substantially circular central portion 10 and contracted'portions 11 and 12 whichproject in opposite directions. By preference, this base body is made from pressed metal and with a depending flange 13 all around as shown. The projecting portions l1 and l12 are similarly made attheir free ends with elongated slots 14 and also with depending guide flanges 15 (Figs. 7 and 8.) Fixed in the flanges 13 and. 15 of cach of the projecting portions 11 and 12 is a pivot stud or pin 16 for pivotally carrying a swing arm presently to be described. .The central portion 10 of the base body is produced or furnished with a raised portion 17 of elliptical form which. as clearly shown in the drawings, extends transversely of thev base body midway between the swing arms 18 and 19 arranged on the end pivot studs 16 between the inner guide iianges 1-5.

The swing arm 18 curves upwardly and inwardly and carries at its extremity a pivot stud 20. This swing arm also has an up.-

wardly projecting branch arm 21 astride ot which is the yoked end 22 of a bridge bar .'23, the .said yoked end 22 being slottedat In the yoked end 26 are provided bayonet slots 28y for the reception of pivot stud or pin 29 which, is passed through the head 27', so that the bridge arm may be detachably connected with the swing arm 19, it being observed in this connection that the pro vision of the slots 211 in the yoked end 22 permits suitable adjustment of the bridge arm upon the pivot stud 25 for the ready engagement o r disengagement of the yoked end 26 with the pivot stud 29 on the headed extremity 27.

30 designates a shackle ring with may be produced in any suitable manner but which as herein shown consists of two lengths of spring wire 31 and 32 suitably bowed to be placed around the raised portion 17 and. having oppositely directed extremities 33 and 34- whieh are bound together by clip members 35. The extremities 33 are bent 'upwardly at an angle at 36 and curved y patch, and finally the about pivot stud 20 whereon the shackle ring is adapted to be swung as about a pivot. The extremities 34 are bent upwardly at 37 and have secured thereto a catch plate 38 which is adapted to be engaged behind an abutment or lug39 provided for the purpose on the headed extremity 27 so as to secure the shackle ring tightly upon an inner tube 40 upon the raised portion 17.

The bridge bar 23 is preferably made with an expanded central region 41 in which is fixed a bearing block 42. Tapped through the bearing block 42 is a hand operated presser screw 43 on the bottom end of which is swiveled a presser shoe 44 adapted to rest upon a suitable plate 45 which may be placed upon a wet cement patch 46, to be applied to the tube 40.

In the use of my improved repair device, the tube 4() to be repaired is laid lengthwise -upon the elliptical raised portion 17 with the punctured or torn area positioned centrally thereof. Thereupon the swing arms 18 and 19 are moved inwardly toward each other and the shackle ring 30 is pressed down around the raised portion stretching the rubber tube uniformly in all directions and thereby opening the pores of the rubber. The shackle ring is pressed down upon the rubber tube about the raised vportion 17 until the catch plate 38 snaps behind lug 39 whereby the shackle ring is held in shackling position. Having thus stretched and shackled the tube upon the raised portion, the next step is to cleanl and roughen the rubber in the usual way by means of any suitable abrasive or rasping tool. Following this operation the cement is applied, the patch 46 is placed upon the punctured or torn'area, the plate 45 is placed upon the bridge bar 23 is lowered and engaged with the swing arm 19 so that the desired pressure may be exerted upon the plate 15-through of the presser screw 43.

By making the raised portion 17 of elliptical form and by supporting the bridge arm and shackle ring by means of the inwardly and upwardly curved swing arms 18 and 19, my repair device is adapted to be employed in patching tional size from the small sized tube for the tire used in connection with vehicles of the Ford type, to the largest size of tubes for tires of the balloon type. In the drawings, where I have illustrated a conventional tube of the smallest size, it will be seen that by making the raised portion 17 elliptical in form, the margins 47 of\ the tube will properly engaged ing and clamping action. By making the swing arms 18 and 19 curved as shown, a

5 balloon type of inner tube may be patched with equal facility since there is abundant the manipulation tires of any Couven-- space between the raised portion and the swing arms to accommodate the marginal edges of the tube without curling or folding the same.

In Figs. 5 and 6, II illustrate my presser shoe as placed upon ya'heat unit vulcanizing patch 48 to be applied to the tube 40. The

s110644, for use in this connection, comprises an elongated plate with depending edge iianges 49 which are adapted to rest upon .a

metallic rim 50 ofthe heat unit vulcaniziri'gg` that the heating material 51 of the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
