Peters, West Roxbury, Mass. Application September 10, 1936, Serial No. 100,189 . 3 Claims. (Cl. 41—35) This invention relates to a method of and means for ornamenting pipe bowls and other articles having curved or angular surfaces for receiving ornamentation. 5 Articles of the nature to which the present invention appertains, are usually formed of wood or ?bre, metal, bone, “Bakelite”, Celluloid, etc., and, in view of the fact that the exterior surfaces are generally curved, it has been prac lO tically impossible for any ornamentation to be added to them after the articles have left the factory. For example it has been desired to place monograms or initials on the curved 'sur faces of the bowls of smoking'pipes but neither 13 the wholesaler nor the retailer of pipes has had any facilities whereby letters or other ornamen tation could be applied to such surfaces. An object of the present invention is to pro vide an equipment for use by the wholesaler or retailer for the purpose of applying ‘letters ac curately and securely to the curved or other surfaces of a pipe bowl or the like whether the same be made of wood, ?bre or any other mate rial. A further object is to provide equipment which enables the letters or other ornamentation to, be applied by anyone with or without skill, the parts' used being simple, easily operated and inexpen sive. 30 A still further object is to provide certain new and novel steps in a method whereby the letters or other ornamentation can be applied and, after being so applied, will be held against accidental removal. 03 U1 With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in certain novel details of construction and combinations of parts and in certain new and novel steps in the method here inafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts and in the steps of the method without‘ departing from the spirit of the invention as 45 claimed. ' In the accompanying drawing the preferred forms of the equipment used in carrying out the method have been illustrated. In said drawing: _ 50 ' Figure 1 is an elevation of the bowl of a smok~ ing pipe showing a special form of jig applied thereto. - Figure 2 shows a boring tool in use for pro ducing recesses in the pipe bowl at the point 55 previously indicated by the jig. Figure 3 illustrates the third step of thread ing the recesses. Figure 4 is an elevation of the pipe bowl show ing the recesses in position ready to receive the studs for ‘holding the letters or other ornamental 5 portions to the bowl." ' Figure 5 is a horizontal section through the , bowl after the ornamental portionshave been applied. , Figure 6 is a section through a portion of the 10 bowl after the applied ornamentations have been burnished so as to lie flat against the curved surface of the bowl. I , Figure 7 shows a modi?ed form of jig. Figure 8 is a section through a portion of a pipe bowl showing recesses for'rec‘eiving ‘inlaid ornamentations. ' ' Figure 9 is an elevation of a slightly modi ?ed form of ornamentation prior to being bur nished onto the surface to which it‘is applied, a portion of the structure engaged by the orna mentation being shown in section. U ‘ In following out the invention the pipe bowl or other object to be ornamented and which can be of any preferred material having a curved. 2 Oi or other surface which is not flat, has applied to it a jig having openings properly located so as to permit marking of the surface‘ through the openings at those pointsadapted to receive the ornamentation to be applied. This jig can be‘ 0 of any desired material and shape. After the surface has been marked as stated, a suitable drill or boring tool is used for forming recesses at the indicated points, these recesses being of exactly the proper depth. Thereafter a tap is inserted in each recess for forming a thread therein. Following this threading operation, the threaded stem or stud projecting from each let ter or other article of ornamentation is forced into the threaded recess leaving the ?at head or ornamental portion bearing against the rounded or other surface of the article to be ornamented. Said head is then burnished so as to be bent back against and conform with the contour of the surface to which it has been applied and bymeans of this last step, the rota tion of the stud or screw extending from the head is prevented and the ornamentation cannot become accidently separated from the structure to which is has been applied. v‘Furthermore, if desired, the‘ stud ‘which is preferably in the nature of a screw,v can be provided with a cement coating so as to cause it to adhere to the wall of the recess in which it is seated. In ?nishing the recess by means of the threadedctap, it is 55 2. 2,133,209 the practice to leave the recess of the exact size of the threaded tap to be inserted thereinto so that no. displacement of the material of the pipe bowl or the like will be effected by the stud when inserted. In carrying out the method stated the jig, one form of which has been indicated at I, can be made of any desired material. ll) It can be a thin resilient plate having hooked arms 2 extending therefrom for engaging the edges of a pipe bowl B. Properly positioned holes 3 can be formed in the jig so that the surface‘ of the bowl can‘be marked accurately at points adapted to be drilled. After the jig has been forced tightly against the strapped about the bowl or other object to be or namented. One jig of this type has been illus trated in Figure 7 wherein hingedly connected plates l6 are carried by straps l1 adapted to be secured about the bowl or other object by means of a buckle I8 or the like. Each plate can be pro vided with an opening through which the location of the ornamentation can be marked. Or, if de sired, these openings, indicated at 19 in Figure 7, surface to be ornamented and said surface has been marked through the holes 3, the jig is re can be shaped like ornamentations which are to 10 be inlaid in the bowl and by means of these open ings l9, it is possible to use the jig as a guide for cutting the recesses 20 in which the ornamenta tions are to be inlaid. Under these conditions a suitable cement is applied for fastening each let ter or other ornamentation in the recess provided moved and there is then used a drill one form of‘ therefor. > which has been shown in Figure 2. This tool in Obviously many other designs of jigs could be used. The feature of prime importance in the present invention is found in the fact that the simple and efficient equipment herein described can be supplied to wholesalers and retailers who are thereby enabled readily to apply different kinds of initials, monograms, etc., to pipe bowls and other small articles sold by them and which 25 cludes a stem 4 having a handle 5 by means of which it can be rotated readily and seated in the stem is the shank 6 of a bit 1.. A stop 8 is mounted on the bit and against the end of stem 4 and serves to prevent the bit from boring a hole which is too deep. In other words that portion of the bit extending beyond the stop 8 will produce a recess of exactly the correct depth. Following the drilling operation which is ef fected at each point previously marked on the pipe bowl, a threading tap 9 is placed in engage have curved or angular surfaces which hereto can be the same as tool 4—5. The threading tap fore have prevented the ordinary dealer from ap plying any particular combination of letters or other ornamentations to meet special orders. Another modi?cation of the invention has been 30 disclosed in Figure 9 wherein the head 2| consti tuting the ornamentation to be applied and which is likewise provided with a stop I2 similar to stop 9, whereby the movement of the tap into the bowl is mounted on the stud or screw 22, is made con cave and is provided with asupplemental spur 23. is limited. The tap is so proportioned as to pro duce a thread in the recess [3 formed in the bowl. Thus after this device has been applied to the bowl B or other structure, the head 2| is burnished as hereto-fore explained and during this latter op ment with the shank [0 of a threading tool hav ing a handle H. Or, if desired, this tool Ill-ll The ornamentations used on the bowl or other structure can be in the form of thin metal letters, eration the spur 23 on the head will enter a small monograms, insignia, etc. In any case the orna each stud is of the same size as the recess adapted to receive it. Therefore each stud can be- screwed recess or‘notch 24, provided therefor. Therefore even though the ornamentation should be ap plied to a flat surface, it will be held in position. What is claimed is: 1., The method of applying ornamentation to the curved surface of an object which includes into the recess provided therefor without causing any displacement of the material of the bowl B. surface at the marked point, threading the recess, mentation, which has been indicated generally at I4, has one or’ more studs projecting therefrom. When a threaded recess l3 is provided in the bowl, Before inserting this stud or screw a coating of cement can be applied thereto so that after the stud has been properly seated, it will adhere to the wall of the recess. Following the insertion of the stud the head M will bear against the bowl but will not lie tightly against it. In order to complete the application of the ornamentation, it is desirable to burnish the 65 head l4 so that it will press back at all, points against the surface of the bowl as shown in Fig ure 6. Consequently this head, by its tight en gagement with the surface of the bowl, will act as a lock to prevent the stud or screw I5 of the head 60 from being unscrewed. Therefore danger of ac cidental displacement of the, ornamentation is avoided. While screw-shaped studs can be used on the applied ornaments, it is to. be understood that 65 many other types of lugs suitable for holding the ornamentation to the bowl might be employed following the formation and proper shaping of the recesses designed to. receive them. It is to be understood furthermore that instead 70 of providing ajig such as has been illustrated, the jig could bev in the form of a ?exible band to be the step of marking said surface, recessing the 46 inserting in. the recess a threaded stud extending from the head of the ornamentation and then burnishing the ornamentation to conform to the curved surface of the object and hold the stud 50 against rotation in the recess in which it is seated. ‘ 2. The method of applying ornamentation to the curved surface of a smoking. pipe or the like which includes the step of recessing said surface . to a predetermined depth, subsequently threading the recess, seating in the recess a cement coated stud having an ornamental head provided with a spur, and thereafterburnishing the head to. ?t it snugly against the curved surface and to force the spur thereinto. ‘ 3. The herein described method of applying or namentation to a substantially cylindrical or other surfacev which?is not flat, which includes the step of marking the surface, forming a recess in the surface at the marked point, placing an ornamentation in the recess, and thereafter bur nishing the ornamentation to conform to the contour of the surface in which it is seated.
