Definitions
- the present invention relates to engraving machines primarily for engraving concrete kerbstones or the like in situ.
- the present invention provides an engraving machine for use in engraving a generally upstanding concretious surface in situ; said machine comprising a main frame, means on the frame for receiving one or more stencils, a carriage, means supporting the carriage at the front of the frame 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 and a stencil guide which can be made to follow a pattern defined by a stencil by movement of the carriage in said plane.
- arms are fitted to the main frame to project outwardly therefrom during use, the arms serving to receive weighted objects to stabilize the machine during the engraving operation, and means are provided for supporting the arms or parts thereof on a supportive surface beneath the arms.
- the arms would usually project rearwardly from the main frame.
- the support means for the arms 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.
- Tubular guides or the like also known from GB 2138748 can define the directions of movement of the carriage.
- means is provided to compensate for the effects of gravity otherwise tending to move the carriage downwardly in its plane of movement.
- the invention provides thrust means for urging the frame towards the surface to be engraved.
- the thrust means can be embodied as piston and cylinder units or rams used in conjunction with the weighted arms which form a rear frame.
- the frame can be carried by a raisable and lowerable jib of a mobile vehicle so that the jib on the vehicle forms the thrust means, at least in part.
- Figure 1 is a perspective view of an engraving machine constructed in accordance with the invention
- Figure 2 is an end elevation of another modified form of engraving machine
- Figure 3 is a schematic part-sectional view of part of the machine showing another modification
- Figure 4 is a schematic part-sectional view of part of the machine showing a further modification
- Figure 5 is a perspective view of a further engraving machine constructed in accordance with the invention.
- Figure 6 depicts a vehicle equipped with an engraving machine in accordance with the invention.
- 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 kerb 30.
- the side members 28 of the frame 11 are linked to rearwardly projecting arms 39.
- arms 39 are separate but could be linked by additional frame members.
- the arms 39 would normally have the same shape but for simplicity 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
- suction devices 13 can serve to clamp the frame 11 to the kerb 30 and as shown in Figure 1, the suction devices 13 are supported 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 arras 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.
- thrust devices 80 such as hydraulic or pneumatic piston and cylinder units serve to urge the frame 11 against the surface to be engraved.
- the devices 80 react against a rigid structure 100 such as a beam or girder forming an abutment.
- Figure 2 depicts another alternative arrangement where the arm 39 is again composed of pivotably linked portions 39', 39" of which the rear portion 39" is inclined to rest on the ground while the portion -39' is supported by adjustable legs 48.
- the carriage 12 tends to move downardly on the guides 21 due to gravity and an operator needs to overcome this bias when raising the carriage 12.
- means is provided to compensate for this.
- a counterweight W is linked via a cable 46 engaged on a rotatable pulley 45 to the carriage 12.
- compression springs 42 can be mounted on the guides 21 between the blocks 22, 20 as shown in Figure 4, to compensate for the effects of gravity on the carriage 12.
- the frame 11 may be carried by a mobile vehicle capable of thrusting the frame 11 firmly against- the kerb 30 under hydraulic or pneumatic force.
- Figure 6 depicts a vehicle 59 which has a raisable and lowerable arm 60 supporting the frame 11 in a detachable manner.
- Thrust devices 61 such as hydraulic jacks, can be interposed between the frame 11 and the arm 60 and used to urge the frame 11 firmly in position against the kerbstone for example.
- the arm 60 or the vehicle can perform this function.
- the above description essentially relates to a product of manufacture which is moreover industrially usable in a useful manner to engrave or mark an existing concrete surface in its external environment in situ.

Abstract
Une machine de gravure adaptée pour graver une surface droite d'une pierre de parement d'un trottoir possède un châssis principal (11) avec une section en canal (27) destinée à recevoir des pochoirs (18) avec des symboles qui sont reproduits à l'aide d'un outil de gravure (29). L'outil (29) et un guide (15) d'engagement d'un pochoir complémentaire sont montés sur un chariot (12). Le chariot (12) peut se déplacer le long de guides tubulaires (21, 19) pour permettre à un opérateur de suivre les symboles définis par les pochoirs (18). Le châssis (11) est stabilisé par des bras (39) s'étendant vers l'arrière et formant des lits qui reçoivent des lests, et les bras (39) sont eux-mêmes supportés par une surface arrière d'ajustement pour faire varier la disposition angulaire du châssis principal (11). Des moyens de poussée (80, 60, 50) peuvent être prévus pour rapprocher le châssis de la surface à graver.An engraving machine adapted to engrave a straight surface of a pavement facing stone has a main frame (11) with a channel section (27) intended to receive stencils (18) with symbols which are reproduced at using an engraving tool (29). The tool (29) and a guide (15) for engaging a complementary stencil are mounted on a carriage (12). The carriage (12) can move along tubular guides (21, 19) to allow an operator to follow the symbols defined by the stencils (18). The frame (11) is stabilized by arms (39) extending rearward and forming beds which receive weights, and the arms (39) are themselves supported by a rear adjustment surface for varying the angular arrangement of the main chassis (11). Pushing means (80, 60, 50) can be provided to bring the chassis closer to the surface to be engraved.
