EMBossING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 572,197, dated December 1, 1896.

i Application filed July 17, 1896. Serial No. 599.509. (No model.)

To LLZZ whom it may concer/1,:

Beit known that I, EDWARD S. DE TAM- BLE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Embossing-Machines, of which the following is a specifica tion.

The object of my said invention is to provide a means whereby an embossing-machine may be employed to ornament curved or circular wooden structures, such as bicyclewheel rims, mud-guards, &c.

An embossing-machine provided with attachments embodying my said invention will be first fully described and the novel features thereof then pointed out in the claims.

Referring to the accompanying drawings,V

which are made a part hereof and on which similar letters of reference indicate similar parts, Figure l is a perspective view of suchan embossing-machine; Fig. 2, a central vertical sectional view of the upper end thereof, and Fig. 3 a detail sectional view on the dotted line 3 3 in Fig. 2.

In said drawings the portions marked A represent the frame of the machine; B, the main roll-carrying shaft; C, the 'embossingroll or die-spindle; D, the burner therein, and E a guide-supporting shaft or rod.

The frame A is a strong, heavy frame suitably arranged to carry the mechanism, and is preferably mainly in the form of heavy castings, as shown. l

The shaft B is mounted in bearings in the heavy vertically-adjustable frame B', which is mounted in ways in the sides of the frame A, and at the upper end extends out into substantially the form `of a table, but with an open upper side. This vertically-adj ustable frame or table is adapted to be raised and lowered quickly to and from certain determinate positions by a rock-shaft 1, having cams 2 and operated by a hand-lever 3. Said cams 2 operate against the blocks 4, which are connected to the rods 5, the upper ends whereof are seated in sockets in the frame B. These rods 5 are screw-threaded and enter screw-threaded perforations in the blocks 4. They are provided with bevel-pinions 6,which engage with corresponding pinions '7 on J[he shaft 8. By this means these rods 5 may be simultaneously revolved and thus the distance between theblocks 4. andthe frame B adjusted. I have shown a sprocketfwheel 9, having a sprocket-chain l0, (running to a suitable hand-operated shaft, not showin) as a means for revolving this shaft; but obviously the sprocket-wheel. 9 might be a plain handwheel and the shaft 8 thus operated directly by hand or any other suitable means for the purpose employed. Said shaft B bears the various disks b, b', and h2, which serve to support the wooden pieces being embossed while the embossing operation is in progress. I have shown three of thevdisks h, three of the disks ZJ', and one disk h2; but obviously any desired number may be employed. These disks are shown as separated by washers and y held in place on the shaft I3 by suitable collars.

The spindle C is hollow and carries the embossing disks or dies c, c,and c2, which correspond to the companion disks b, h', and b2 and which are engraved on their peripheral surfaces with the figures desired to be embossed on the wood. Said disks are separated by washers and secured upon the spindle in the same manner that the corresponding disks are separated and secured upon the shaft B. This spindle is supported by heavy rollerbearings at each end and comes directly in contact with the rollers C', forming the operative part of said bearings.

The burner D is a tubular burner and eX- tends within the opening in the spindle C. Securely attached to the outer end of this burner is the cap D', which rests immediately within the extreme outer end of the spindle C and is adapted to support the burner, although it is not fastened to said spindle, and is consequently capable of remaining in its position while the spindle revolves. Said cap D has anumber of fine perforations surrounding the opening, by which the burner D is coupled thereto for the admission of air, and the spindle C is provided with perforations at the other end of the burner, as shown in Fig. 2, for the escape of I[he products of combustion. A neck or elbow D2 is connected to the cap D', and to this in turn is connected a flexible tube or hose D3, which leads to a IOC mixer D4, to which the gas-pipe D5 leads, whereby the fuel-gas, which I prefer to use with this maehinefis suppliedthereto.

The shaft or rod E is mounted in bearings e on standards E on the frame A. These standards are slotted and the bearings are thus rendered adjustable, as plainly shown, so as to accommodate the guides to Work of different size. Upon the outer end ofthis shaft or rod are the guide-rollers E2, which engage with and support the bicyclerims while being embossed.

In the machine as illustrated the provision is made for the embossing of three Wheelguards X, three Wheel-rims Y, and one chainguard Z. The Wheel-guards X, being in the form o f strips, although somewhat curved, may peras. Within the machine; between the bealnsS in. the freme'rhh efry'therolls' and/dies, Therilns Y being ann ular in form, if. i'S. lfeeessaiiy that' thefllls and, dies., by Which-'they et@ treated. Should be' 'outside the bearing in orderJ that they maybe removed and' replaced. It isfals'o rdesirable that the Cham-euere be Similarly olitsid'f the beelting, for, irhile noteofnipletely connected tof gether at the ends, vit is of such formY to render, itsintroduction inside of thefbearin gs very difficult. As the rims'Y extend a considerable distanceabove the point Where they areoperated L ipon, it is necessary that their upper and otherwise free portions, should be accurately supported in position, iny order that the Werl; may be' uniform, 'and' thefshaft E, with its"guiderolls E2, Vis provided accord ingly, said guide-rolls being held between collars e2, as shown, which prevent them from moving endwise of the shaft by which they are carried, although left free to revolve thereon.

'In order that the rims Y may bel removed and replacedy readilyvwithout uneoupling the fuel hoseor tube D3, said tube is bent around and condueted back', substantially parallell with thespindle C, to apoint outside of the rolls and dies by Which the rimsare treated.

By the machine shown I find that Iv am enabled to satisfactorily.emboss these thin Wooden parts, which have not heretofore been capable of being successfully provided with ornamentation of this character. Manifestly, from the nature of the structures to be so operated upon, ythe embossing must not be deep, and consequently the spindle and shaft may extend outside the bearings by which they are supported and still have sufficient strength and rigidity to perform'the Work.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in an embossing-ma chine, of a main framework, an adjustable frame or table, a main shaft carried thereby and having an end which projects to the outsideof the framework of the machine, and is there provided with supporting disks or roll- Iersl for the Work toy be treated, a spindle mounted inbearings in the main vframework and alsdertendin gtooutsfidethe frame of the machine, @11d the@ Provided, with.. embossing rolls 0r dies. a' burner Withe Said Spindle, a caploosely' monnted in the en d of said spindle' and adapted 'to remain stationaryvwhile the latter revolves: forcarrying theburn er at its outer end, a flexible coupling connected to said cap and extending back` substantially parallel with the spindle' toz alongside the frame and theneeto thega's-,fuel-supply pipe, and said pipe, Wherebyvvheel'frims and similar annular stru cturesmaybe embossed upon their interior sides, substantiallyas` shown and described.

2. AnV embossing 1 machine, the spindle whereof extends tov ontside the framework thereof and .carries embossing rolls or dies thereon, and av heat-supplying tube connected to the burner-cap in the outer end of the spin.-

dle and extending then ce back alongside the spindle, to'y near the framework, thus enabling annnlar structures to be placed over the spindle and` operated upon, substantially as and for the purposessetI forth.

In Witness ivhereof'I have hereunto set my hand and seal, at Indianapolis, Indiana, this lthday of July, A'. D. 1896. V
