1 Claim. 1

This invention relates to a trophy engraving machine.

It is an object of the present invention to provide with a trophy engraving machine a simple and practical means for retaining the trophy in a fixed and rigid manner which is adjustable easily and readily to receive the trophy and to release the same from the machine.

It is another object of the present invention to provide in a trophy engraving machine a convenient means for effecting the engraving out upon the trophy which has a tracer arm which can be conveniently located adjacent to the user and upon the patterns conveniently placed adjacent the base of the trophy and wherein the tracer arm can be adjusted upwardly and lifted to an out-of-use position and the engraving equipment readily swung away from the opening into which the trophy has been extended and retained by the holder and wherein the entire arrangement is a self-contained unit adapted to rest upon a table or flat surface in a position to be conveniently used.

Other objects of the present invention are to provide a trophy engraving machine which is of simple construction, compact, inexpensive to manufacture and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is a top plan view of the trophy engraving machine embodying the features of the present invention.

Fig. 2 is a longitudinal cross-sectional view in elevation, taken on line 2-2 of Fig. 1.

Fig. 3 is a front elevational view of the engraving machine.

Fig. 4 is an enlarged cross-sectional view taken through the operating linkage and generally on line 44 of Fig. 1.

Referring now to the figures, l3 represents a base of heavy construction which is open at the center as indicated at [I to receive a trophy l2. In the bottom of the base, there is an opening or recess |3 in which is adjustable a plate l4 having a cushion |5 therein serving to hold the trophy in place and provide a soft rest therefor. This plate has a depending threaded shank 5 which is adjustable through a portion ll of the base and which is locked by a nut l8.

At opposite sides of the base, there are extended into the space H to retain the trophy a similar holding element l9. This element l9 comprises a base 2| with a cushion 22 thereon adapted for engagement with the side of the trophy. Extending from the plate 2| is a slide portion 22 which is adjustable in a recess 23 when an adjusting screw 24 threadedly connected as indicated at 25 with the portion 22 is turned.

Extending from the rear of the base I0 is a bracket portion 21 on which is journalled or piv oted a driving motor 28. This driving motor has a pulley pinion 23 to which is connected a belt 3|. A projection 32 is provided on the opposite side of the pivot connection of the driving motor 23 with the bracket portion 21, and to the projection there is connected a tension spring 33, anchored to a lug 34, whereby to normally pivot the driving motor in a clockwise direction as viewed in Fig. 1 whereby to tighten the belt 3|. Extending upwardly from the top of the base II] are upright portions or bearing brackets 35 for receiving a shaft 36 to which is fixed a plate 31 on which a copying frame is carried and which is formed with a link 39 which is pivotally mounted on the plate by a pin 40. The opposite end of the link 39 is pivotally connected to an arm 4| by a pin 5 and the end of the arm 4| is pivotally connected to a link 38 by a pin 6. The link 4| has a bifurcated portion 42 in which is pivotally connected a tracer arm 43 having a tracer point 44 and a handle 45 thereon. The tracer arm 43 can be pivoted upwardly and rearwardly when out of use or it can be extended downwardly for engagementof the tracer pin 44 with patterns or indicia 45 conveniently carried on a bridge support 41 extending between the sides of the base In and upwardly therefrom.

Extending forwardly from a pivot point 48 at the end of the link 38 is an adjustable arm 49 which carries a pulley wheel 5| on which the belt BI is positioned and the pulley is carried on a shaft 52 which is journaled in the arm 49 and carries a tool 53 at its lower end. In order that the tool can be adjusted by means independently of the tracer arm 43, there is provided an extension 54 with a knob 55 thereon. This arm 49 serves as a follower for the movements of the tracer arm 43 and is adjustably connected to the link 39 by a pivot bolt 51 which is threaded in the arm 39 as indicated at 58. The arm 49 is provided with a slot 5i! through which the bolt '51 extends. The arm 43 is formed of relatively adjustable par ts so that the same can be extended to properly locate the tool 53 upon the work surface. Indicia 59 is provided on the arm part to assist in the adjustment of the relatively adjustable parts thereof. Similar indicia is provided for the adjustment of the cushions 22 engaging with the 3 sides of the trophy as indicated at 6| whereby to properly center the trophy within the space H of the base.

The patterns 46 are locked in place in a channel 52 on the top of the bridge 4! by adjustable lock plates 63 having locking screws 64 thereon.

As a further support for the trophy upon the cushion 15, there is provided at the inner end of the opening 1 I and upon the base a cleat or arm 65 which is retained in place on the base by a clamping device 66 and adapted so as to be adjusted to properly enter the top edge of the trophy and wherein a soft engaging pad 61 will engage the inner surface of the trophy at the top thereof.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

I claim:

In a work holder for an engraving pantograph, the combination which comprises a base having a work receiving opening in the upper surface with a side wall at one side of the opening for supporting scribing and engraving tools and end walls at the ends of the opening for supporting work positioning means, said base having a recess centrally positioned in the opening and extended. downwardly from the said opening, a vertically movable horizontally disposed plate positioned in the said recess, an adjusting screw upon which said plate is carried extended downwardly from the plate through the said recess, adjusting nuts on the said screw for adjusting the elevation of the said plate in relation to the upper surface of the base, vertically disposed plates positioned in the sides of the opening of the base, means ad justably mounting the said vertically positioned plates in the said end Walls of the base, cushions on the said vertically and horizontally disposed plates, an arm in the opening of the base positioned to extend into an opening in work positioned on the cushion of the said vertically movable horizontally disposed plate, a vertically disposed screw extended through said arm and threaded into the base, and an adjusting nut positioned on said vertically disposed screw for clamping the arm against the inner surface of work positioned on the cushion of the said horizontally disposed plate.
