Abstract
An engraving machine adapted to engrave an upstanding surface of a kerbstone has a main frame (11) with a channel section (27) for receiving stencils (18) with symbols to be replicated by an engraving tool (29). The tool (29) and a complementary stencil-engaging guide (15) are mounted on a carriage (12). The carriage (12) is displaceable along sets of tubular guides (21, 19) to enable an operator to follow the symbols defined by the stencils (18). The frame (11) is stabilized by rearwardly extending arms (39) which form beds for receiving weighted objects and the arms (39) are themselves supported on a rear suface for adjustment to vary the angular disposition of the main frame (11). Alternatively thrust means (80, 60, 50) can urge the frame towards the surface to be engraved.
Description
SPECIFICATION
Improvements in engraving machines
The present invention relates to engraving machines primarily for engraving concrete kerbstone or the like in situ.
A known engraving machine of the type with which the present invention is concerned is described in GB
Patent Publication No 2138748. A general object of the present invention is to improve the known form of machine.
The present invention provides an engraving machine for use in engraving a generally concretious surface in situ; said machine comprising a frame, means on the frame for receiving one or more stencils, a carriage, means for supporting the carriage for movement relative to the frame within a plane parallel to the surface to be engraved, an engraving tool or tool holder supported by the carriage for permitting the tool to engage the surface to be engraved, a stencil guide which can be made to follow a pattern defined by a stencil by movement of the carriage in said plane and means for compensating for the effects of gravity otherwise tending to move the carriage downwardly in said plane.
As is known from GB 2138748, suction devices may also be provided to clamp the main frame to the surface which is to be engraved, but as an alternative thrust devices can be used. Alternatively or additionally there can be provided arms fitted to the frame to project outwardly from the frame, and conveniently rearwardly beyond the surface to be engraved, means for adjustably supporting the arms on a support surface therebeneath and means on the arms for receiving weighted objects to stabilize the machine during the engraving operation. Conveniently the support means for the arms, which can constitute a rear frame, permits these arms to be adjusted in inclination thereby to bring the main frame into a desired orientation vis a vis the surface to be engraved, e.g. a face of a kerb. The support means can take the form of screw-threaded spindles on the arms or parts thereof.
The machine can also be mounted in an elevated position on an adjustable base frame.
As is also known from GB 2138748 elongate guides, such as tubular rails, can define the paths of movement of the carriage in orthogonal directions, side-to-side and up and down. The compensation means can take the form of a counter-weight linked to the carriage with a cable. In another construction springs are used to bias the carriage upwardly.
The invention may be understood more readily and various other aspects and features of the invention may become more apparent from consideration of the following description.
Embodiments of the invention will now be described, by way of examples only, with reference to the accompanying drawings, wherein:
Figure 1 is a perspective view of an engraving machine of the type with which the invention is concerned;
Figure 2 is a schematic part-sectional end view of part ofthe machine showing a modification in accordance with the invention;
Figure 3 is a schematic part-sectional end view of the machine showing a further modification in accordance with the invention; and
Figure 4 is an end elevation of the machine in combination with a mounting frame.
In the accompanying drawings, the reference numeral 10 denotes an engraving machine and as depicted in Figure 1 the machine 10 is composed of a frame 11 with side members 28 and a channel-like transverse structure 27 which receives cut-out stencils 18. Bearing blocks or collars 20 are mounted for sliding along a pair of tubular guides 19 disposed between the side members 20. A pair of tubular guides 21 interconnect the blocks 20 and a carriage 12 in turn slidably mounted on the tubular guides 21 with the aid of bearing blocks or collars 22. The guides 21 extend perpendicular to the guides 19. The carriage 12 has a handle 24 for displacing the carriage 12 along the guides 21 in the direction of arrows C-D. The guides 21 are additionally connected at their ends with a cross-piece serving as a handle 25 for displacing the carriage 12 along the guides 19 in the direction of arrows A-B.The carriage 12 supports a stencil-engaging guide 15 which an operator can displace by moving the carriage 12 as appropriate to follow the shape of the stencils 18. A rotary engraving tool 29 with a replaceable hardened bit is likewise supported by a holder on the carriage 12 and follows the path described by the guide 15 to permanently mark a generally upstanding surface of a kerb 30. Suction devices 13 serve to clamp the frame 11 to the kerb 30.
As shown in Figure 1, the suction devices 13 are suppoted by arms 31 which are linked to the side members 28 for pivoting universally or up and down as indicated by arrows S. This pivotal motion can be disabled by operating levers 32 or the like to lock the arms 31 to the side members 28. This permits the frame 11 to be positioned and clamped in an appropriate orientation depending on the depth of the kerb 30 and its angular rake. Instead of suction devices 13 thrust devices such as hydraulic rams in association with some other abutment-forming equipment can be used to urge the frame 11 against the kerb 13. Both thrust or suction devices can however be omitted since the frame 11 is subjected to additional stability and rigidity by means of an auxiliary rear frame or structure which can carry weighted objects.As shown, the side members 28 of the frame 11 are linked to rearwardly projecting arms 39. These arms 39 are separate but could be linked by additional frame members. The arm 39 at the right-hand side of the drawings is cranked and one-piece while that at the left hand-side is, as an alternative, composed of two pivotably-connected portions 39', 39". L-shaped cross pieces 40 on the arms 39 provide beds for weighted blocks 41 which can be stacked one on another. The arms 39 are supported by means of adjustable screw-threaded spindles 42 with pads 43 at their lower ends. By adjusting the spindles 42 up and down the disposition of the main frame 11 can be altered to adjust the angular disposition of the kerb 30.
The carriage 12 tends to move downwardly on the guides 21 due to gravity and an operator needs to overcome this bias when raising the carriage 12. In accordance with the invention means is provided to compensate for this. Thus, as shown in Figure 2, to assist in controlling the displacement of the carriage 12 a counterweight W is linked via a cable 46 engaged on a rotatable pulley 45 to the carriage 12. Alternatively compression springs 47 can be mounted on the guides 21 between the blocks 22, 20 as shown in
Figure 3 to compensate for the effects of gravity on the carriage 12.
Figure 4 depicts the machine 10 with the compensation means of Figure 2 or 3 mounted to a base frame 50 adjustable with screw devices 51 or the like to bring the machine 10 into an elevated disposition vis a vis an upstanding wall surface 30 to be engraved.
The main frame 11 of the machine 10 is supported on the frame 50 directly or by means of one or more rams 52.
