  • Suitable conduits 102 are connected to vibrator 100 for admitting and exhausting air under pressure to and from vibrator 100.
  • the purpose of vibrator 100 is to induce vibrations in strip inserting apparatus 20 to facilitate the insertion of strip S into the expansion joint slot and is particularly advantageous when inserting strips of relatively large diameter sizes. For smaller diameter strips, vibrator 100 is not necessary and can be removed from strip inserting apparatus 20.
  • Means are provided to actuate jaw members 22 and 24 alternately in a step-by-step manner axially along strip S.
  • Such means comprises a pneumatic actuator 104 comprising a cylinder 106 and a reciprocable piston (not shown) connected to a piston rod 108.

If desired, other types of actuators can be used within the purview of this invention.

  • FIG. 10 illustrates the arcuate movement of links 26 and 28 and the gripping surfaces 62 and 64 of jaw members 22 and 24. Since the movement of both links 26 and 28 are substantially identical, it is believed that a description of the movement of link 26 only will sufiice.
  • Letters A and B represent the pivot axes of pins 30 and 36 of link 26 as shown in FIG. 2. Arrows C and D indicate arcuate movement of these pivot axes and arrows E and F indicate arcuate movement of a given point on gripping surfaces 62 and 64.
  • pivot axis A of link 26 remains fixed while the pivot axis B of link 26 moves in an arcuate direction along arrow D to point B upon retraction of piston rod 108.
  • Link 26 carries jaw member 24 along with it in the same arcuate direction and gripping surface 64 moves along arrow F as shown in FIG. 10.
  • the pivot axis now represented by B remains fixed while pivot axis A moves along arrow C to point A.
  • Side wall 62 of jaw member 22 also follows a similar arcuate path along arrow E.
  • Elongated slots 34 and 42 permit further relative sliding movement between jaw members 22 and 24 when upper side walls 48 and 50 abut prior to completion of the jaw member movement. The above described cycle is repeated to effect a step-bystep movement of jaw members 22 and 24 in a walking fashion along strip S.
  • FIG. illustrates only the theoretical relative link and gripping surface movement and does not represent jaw member movement nor movement of strip S caused by inertia and compressive forces.
  • gripping surfaces 62 and 64 In operation, with gripping surfaces 62 and 64 in engagement with opposite sides of a strip, jaw members 22 and 24 move in opposite arcuate directions. However, the forward movement of one jaw member will exceed the rearward movement of the other jaw member to effect an overall forward advancement of the jaw members relative to strip S for the following reasons.
  • Strip S is in a compressed state between gripping surfaces 62 and 64 and tends to bulge laterally outwardly against such surfaces during their respective arcuate movement to substantially fill the now wider space.
  • jaw member 22 when jaw member 22 moves in an arcuate forward path, due to extension of piston rod 108, cammed surfaces 70 of indentations 66 enable these surfaces to slip relative to strip S allowing jaw member 22 to move forwardly. Simultaneously, jaw member 24 tends to move in an opposite rearward direction. However, portions of strip S will bulge into the spaces defined by indentations 66 and be compressed by shoulder 68 upon rearward movement of jaw member 24 until a reaction force is sufficiently induced in such portions of strip 5 to stop further reverse movement of jaw member 24. Jaw member 22 continues to move forwardly until it completes the end of its travel as shown in FIG. 4 while jaw member 24 remains substantially stationary.
  • jaw member 24 moves forwardly by reason of slippage of cammed surface 70 relative to strip S and jaw member 22 moves rearwardly until stopped by the reactive bearing pressure of compressed strip S on shoulders 68 of jaw member 22. law member 24 continues to move forwardly until it reaches the end of its stroke as shown in FIG. 5.
  • strip S is progressively inserted in expansion joint slot S by means of downwardly inclined surfaces 56 and 58 and finally inserted to the desired depth by wheel 86. Shoulders 90 bear against the top wall side portions of strip S to insure proper disposition of strip S within the slot.
  • FIG. 11 illustrates another form of the invention particularly adapted for accommodating varied diameter sizes of sealing strips.
  • This form of the invention is identical to the form previously described with the exception that adjusting means are provided for varying the spacing between the side walls 48 and 50 of jaw members 22 and 24.
