SPADING ATTACHMENT FOR CONCRETE-FINISHING MACHINES.
Application filed July 11,
The present invention relates to attachments for concrete paving finishing machines, and more particularly to an attachment arranged for operation with the machine and adapted to trim the rough edges of the con crete at the edge of the concrete form or mold at the side of the pavement.
A further object of. the invention is to provide an attachment of this character arranged for moving over the work, together with the finishing machine, and having a cutting blade for trimming the rough edges of the concrete at the side of the pavement and arranged for vertical adjustment so as to regulate the depth of the cut of the blade.
An additional object of the invention is to provide spring means for yieldably retaining the cutting blade for trimming the edge of the pavement at a predetermined depth and adapted to ride over any obstructions with which the blade may come into contact during the operation thereof.
A still further object is to provide an attachment of this character of a simple and practical construction, which is strong and durable, which may be quickly and easily installed in operative position upon the finishing machine without necessita tingany material changes in the construction thereof, and otherwise well adapted to the purpose for which the same is intended.
Other objects and advantages of the invention will reside in the special construction and combination of the various elements comprising the invention, reference being had to the accompanying drawings forming a part thereof, wherein:
Figure 1 is a side elevational view of the attachment shown in position at the front end of the frame of the finishing machine.
Figure 2 is a top plan view, and
Figure 3 is a rear elevational View.
Referring to the drawings in detail, for the purpose of illustration, I have disclosed a preferred embodiment of my invention, comprising a pair of attaching plates 5 secured at the opposite side edges of a concrete finishing machine frame 6, of a type well known in the art, for finishing the surface of concrete roads or pavements. The ends of the plates 5 yond the end of the rame 6, and has the material at its extremities formed into a hearing 7 for supporting a horizontally disposed hinge pin 8. The pins 8 at each side of the frame provide a pivotal mounting for the rotrude slightly be- 1828. Serial No. 291,889.
ends 9 of a cutter frame 10, preferably constructed of a pair of strips of strap iron having their ends adjacent the pivotal connection curved inwardly toward each other and with their free ends disposed in slightly spaced parallel relation as shown at 7, and extended in a rearwardly extending direction. A bolt 12 extends transversely to the ends of the frame member, upon which is rotatably mounted a disc 13, and disposed between the parallel ends 11 of the frame. The cutting edge of the disc is bevelled at one side as shown at 14. A vertically disposed supporting member 15 is suspended from the rear end of'the frame 6 of the finishing machine having an opening formed in its lower end, through which is threaded an adjusting bolt 16 secured in adjusted position with respect to the supporting member by a wing nut 17. The rear end of the bolt 16 is formed into a hook 18, to which one end of a coil spring 19 is attached having its opposite end attached to the cutter frame, intermediate its ends. The spring 19 thus serves to yieldably retain the outer end of the cutter frame downwardly in a position for engagement of the disc withthe ground. A supporting arm 20 extends rearwardly from the finishing machine frame in a slight ly downwardly inclined angle, said supporting arm preferably being composed of a pair of slightly spaced parallel strips of strap iron, indicated at 21,. having one end of each thereof, bent angularly as indicated at 22, for attachment to the rear of the frame 6. A vertically disposed quadrant 23 is attached to the supporting arm 20, having ratchet teeth 24 formed in its upper outer edge and with which is associated a ball 25, carried on a lever 26, pivoted at its lower end to a bolt 27, extending transversely of the supporting arm 20, at a point equi-distantly between the ends of the quadrant. A link 28 connects the lever with the cutter frame 10. A coil spring 29 is also attached at one end to the lever, with its opposite end attached to the rear end of'the supporting arm 20 and arranged to yieldably netain the lever in a position at one end of the quadrant and cooperating with the spring 19 to retain the cutting frame in a downwardly disposed position.
In the operation of the device, the parts of the attachment are arranged in the position shown by full lines in Figure 1 of the drawings, so that the disc 13 occupies a position at the edge of the concrete mold or form at the side of the pavement or roadway. It is to be understood that the device is placed in use while the concrete is in a plastic condition so as the cutter is moved over the work by the finishing machine, the edge of concrete will be trimmed by the cutter and thus serves to provide a neat finish for the work. WVhen the spading attachment is not designed for use, the lever 22 is moved upwardly and forwardly into a position as shown by dotted lines in Figure 1 of the drawings, whereby to raise the cutter and cutting frame out of engagement with the work. By adjusting the tension of the spring 19, through the adjusting bolt and wing nuts 16 and 17, respectively, the depth of the cut made by the disc may be regulated. It is obvious that the invention is susceptible of various changes and modifications, without departing from the spirit or i scope of the invention or sacrificing any of 1ts advantages, and I accordingly claim all such forms of the device to Wl11Cl1 I am en- 7 titled.
of the discs, and means sup iorted from the machine and operatively connected to said spade frame for the vertical ad ustment thereof,
2. A spading attachment for concrete finishing machines comprising a spade frame pivotally attached to the frame of the machine and including a pair of spaced parallel frame members, a cutting disc rotatably mounted on said spade frame and disposed between said frame members whereby to form 'a-guide for diametrically opposite edges of the discs, spring means yieldably maintainin g the cutter in engagement with the ground, adjusting means for said spring means, adjusting means for said spade frame supported by the machine and a link connecting said spade frame adjusting means to said frame.
'3. Bi spading zttachment for concrete finishing machines comprising a spade frame pivotally attached to the frame of the machine, a cutting disc rotatably mounted on said spade frame, spring means yieldably maintaining the cutter in engagement with the ground, adjusting means for said spring means, adjusting means for said spade frame supported by the machine, and a link connecting said spade frame adjusting means to said frame, said spade frame comprising a pair of frame membershaving one end pivota attached to the frame of the machine at opposite sides thereof and secured to each other at their free ends in slightly spaced relation and a shaft for the cutter carried at the free ends of said frame member, supporting the cutter for rotation. between the frame members, said members constituting a guide for the cutter.
