3' Glaims.

This invention'relates to engraving. block at taohments and has for an object to provide an attachment adapted tohold large pieces of hollow were such as-silver loving cups, pitchers,; candle- ;sticks,' and so forth.

A further object is toprovide an attachment of this type which may be adjusted vertically as well: as horizontallyto' receive large pieces of hollow ware of various shapes and sizes.

A further object is to provide a device of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a longitudinal sectional view of an engraving block attachment constructed in accordance with the invention.

Figure 2 is a top plan view of the parts shown in Figure 1.

Figure 3 is a bottom plan view of the device. Figure 4 is a cross sectional view taken on the line 44 of Figure 1.

Figure 5 is a cross sectional view taken on the line 55 of Figure 1.

Figure 6 is a longitudinal sectional view of a modified form of the invention taken on the line 66 of Figure '7.

Figure '7 is a top plan view of the parts shown in Figure 6.

Figure 8 is a cross sectional view taken on the line 8-8 of Figure 6.

Figure 9 is a cross sectional view taken on the line 99 of Figure 6.

Referring now to the drawings in which like 45 characters of reference designate similar parts in the various views, 8 designates the extensible jaws of a conventional engravers block. The novel attachment for large work, comprising the sub-. ject matter of this invention, includes a substan- 50 tially U-shaped wood base comprising longitudinal side members 9 and a cross member ID secured to the side members by screws H.

A pair of resilient metal Z-bars l2, best shown in Figure 5, are secured to the underneath faces 55 of the side members by screws I3, and these bars are of sufficientlength to; extend substantially the entire length of the base, as best shownlin Figure 3. The bars are resilient so as to readily be clamped, against the edges of the slide M: and hold the: slide stationary at adjusted positions longitudinally of the base to accommodate hollow ware of various lengths,

The slide Hi isformed of a; substantially rectangular piece of wood of substantially the same thickness as the base, and is slidably received in the Z-bars 42 below the base. The slide is provided with a longitudinal slot I 5 to receive projections of any kind on the hollow ware. The slide may be slid inwardly or outwardly relatively to the base to receive the particular article to be engraved, and the device may be then inserted between the extensible jaws 8 of the engravers block, as shown in Figure 4, tightening of the jaws forcing the Z-bars into tight frictional engagement with the edges of the slide and looking the slide in the adjusted position.

A jaw I6 is secured to the base by screws I! passed upwardly through the cross member H) of the base as shown in Figures 1 and 3. The jaw is provided with an arcuate working face 18 which provides an upper finger l9 and a lower finger 20 either of which may be engaged with the article to be engraved to hold one end of the article stationary on the base. I

The slide l4 is'provided with a jaw 2| which is secured to the slide by screws 22 passed upwardly through the slide on opposite sides of the slot I5 and into the bottom of the jaw, as best shown in'Figures 1 and 3. The jaw is provided with a concave working face 23 which confronts the working face of the jaw I6 and provides a single finger 24 and a shoulder 25 for engagement with one end of the work to be engraved to hold the same stationary.

A modified form of the invention illustrated in Figures 6 to 9 inclusive has the same identical parts as the form of the invention shown in Figures 1 to 4 and these parts consequently are designated by the same reference characters. By referring to Figures 6 to 9 it will be seen that jaws 26 and 21 are provided for holding flat work to be engraved, such as for example, platesl, platters, and the like.

, The jaw 26 is provided with a pair of spaced stems 28 which are frictionally engaged in openings 29 and 30 formed in the superposed fingers l9 and 2|] of the jaw l6, as best shown in Figure 9. The stems are screw threadedly engaged in the jaw so that the jaw may be reversed on the stems to dispose either of its longitudinal working faces 3| or 32 in engagement with the work. Both working faces are concave and are provided respectively with a plurality of slots 33 and 34 of different contours and depths for holding various large flat articles.

The jawZ'Iis a duplicate of the jaw26. The jaw is equipped with a pair of relatively long stems 35 which are engaged through openings 36 formed in the slide l4 on opposite sides of the slot l5 therein. The stems frictionally engage the walls of the openings so that the jaw may be supported at various vertically adjusted positions. The stems furthermore engage the finger 24 of the fixed jaw 2| on the slide l4 and this finger reinforces the stems to resist vibration.

By sliding the jaws 21 upwardly and downwardly flat artiles of various depths may be rigidly supported during the engraving operation.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

1. An engravers block attachment comprising a base, spaced resilient bars extending longitudinally of the base and adapted to be clamped between the jaws of an engravers'block, a slide disposed between the bars, pressure of the jaws of engravers block upon said resilient bars deforming the bars to clamp the slide at various adjusted positions longitudinally of the base, and work holding means on the base and on the slide.

2. An engravers block attachment comprising a base, spaced resilient bars extending longitudinally of the base and adapted to be clamped between the jaws of an engravers block, a slide disposedbetween the bars, pressure of the jaws of engravers block upon said resilient bars deforming the bars to clamp the slide at various adjusted positions longitudinally of the base, and work holding jaws on the base and on the slide having concave working faces provided with work engaging fingers.

3. An engravers block attachment comprising a base, spaced resilient bars extending longitudinally of the base and adapted to be clamped between the jaws of an engravers block, a slide disposed between the bars, pressure of the engravers block upon said resilient bars deforming the bars to clamp the slide at various adjusted positions longitudinally 01 the base, supports on the base and on the slide, stems mounted for vertical adjustment in said supports, and work holding jaws carried by said stems.
