  • a cement applying mechanism comprising: a nozzle mounted for movement in a rearward direction in a cement applying stroke between an initial location and a final location and mounted for swinging movement about an upright axis; cement flow directing means in said nozzle, through which cement may be ex truded from said nozzle,extending radially from said axis; means for moving the nozzle through said cement applying stroke; means so constraining the nozzle that said cement flow directing means is directed laterally of said rearward direction and outwardly from said axis during movement of the nozzle in said cement applying stroke from said initial location to an intermediate location between said initial and final locations; and means operative when the nozzle has reached said intermediate location to so swing the nozzle rearwardly and inwardly about said axis that said cement flow directing means is directed generally rearwardly from said axis when the nozzle has arrived at said final location.
  • the mechanism of claim 1 further comprising: a forwardly facing stop surface; an operating member located forwardly of said stop surface; a beam, located forwardly of the stop surface in intersecting relationship with the stop surface, mounted for rearward movement with the nozzle, the engagement of the beam with the stop surface being determinative of said final nozzle location; an actuating member mounted to the beam for rearward movement therewith in intersecting relationship with the operating member, the intersection of the actuating member with the operating member being determinative of said intermediate nozzle location; and means responsive to the intersection of the actuating member with the operating member for swinging the nozzle as aforesaid.
  • the mechanism of claim 1 further comprising: a nozzle carrier; a nozzle mount, to which the nozzle is affixed, mounted to said carrier for swinging movement about said axis to thereby form said mounting of the nozzle for swinging movement about said axis; means mounting the carrier for rearward movement to thereby form said mounting of the nozzle for movement in said rearward direction; means for moving the carrier rearwardly to thereby form the means for moving the nozzle through said cement applying stroke; a motor mounted to the nozzle carrier; and connecting means extending between the motor and the nozzle mount; wherein said means for constraining the nozzle as aforesaid comprises means for causing the motor to enable said connecting means to so position the nozzle mount that said cement flow directing means is directed laterally of said rearward direction and out wardly from said axis; and wherein said means to swing the nozzle as aforesaid comprises means for actuating the motor to cause the connecting means to so swing the nozzle mount about said axis that the nozzle swings rearward
  • the mechanism of claim 1 further comprising: means mounting the nozzle for inward-outward movement; stop means limiting the extent of inward movement of the nozzle; means yieldably urging the nozzle outwardly at the beginning of the cement applying stroke; and means, effective when the nozzle is between said intermediate and final locations, to cease the outward urging of the nozzle and to cause the noz- 6.
  • the mechanism of claim further comprising: a forwardly facing stop surface; a first operating member and a second operating member located forwardly of said surface; a beam, located forwardly of the stop surface in intersecting relationship with the stop surface, mounted for rearward movement with the nozzle, the engagement of the beam with the stop surface being determinative of said final nozzle location; a first actuating member mounted to the beam for rearward movement therewith in intersecting relationship with the first operating member, the intersection of the first actuating member with the first operating member being determinative of said intermediate nozzle location; means responsive to the intersection of the first actuating member with the first operating member for swinging the nozzle as aforesaid; a second actuating member mounted to the beam for rearward movement therewith in intersecting relationship with the second operating member, the second operating member and the second actuating member being so constructed and arranged that their intersection takes place when the nozzle is between said intermediate and final locations; and means responsive to the intersection of the second actuating member with the second operating member to cause said cessation of the outward
  • the mechanism of claim 5 further comprising: a nozzle carrier; a nozzle mount, to which the nozzle is affixed, mounted to said carrier for swinging movement about said axis to thereby form said mounting of the nozzle for swinging movement about said axis; means mounting the carrier for rearward movement to thereby form said mounting of the nozzle for movement in said rearward direction; means for moving the carrier rearwardly to thereby form the means for moving the nozzle through said cement applying stroke; a motor mounted to the nozzle carrier; and connecting means extending between the motor and the nozzle mount; wherein said means for constraining the nozzle as aforesaid comprises means for causing the motor to enable said connecting means to so position the nozzle mount that said cement flow directing means is directed laterally of said rearward direction and outwardly from said axis; and wherein said means to swing the nozzle as aforesaid comprises means for actuating the motor to cause the connecting means to so swing the nozzle mount about said axis that the nozzle swings rearwardly
  • the mechanism of claim 7 further comprising: a forwardly facing stop surface; a first operating member and a second operating member located forwardly of said surface; a beam, located forwardly of the stop surface in intersecting relationship with the stop surface, mounted for rearward movement with the nozzle carrier, the engagement of the beam with the stop surface being determinative of said final nozzle location; a first actuating member mounted to the beam for rearward movement therewith in intersecting relationship with the first operating member, the intersection of the first actuating member with the first operating member being determinative of said intermediate nozzle location; means responsive to the intersection of the first actuating member with the first operating member for causing the motor to swing the nozzle mount as aforesaid; a second actuating member mounted to the beam for rearward movement therewith in intersecting rela tionship with the second operating member, the second operating member and the second actuating member being so constructed and arranged that their intersection takes place when the nozzle is between said intermediate and final locations; and means responsive to the intersection of the second actuating member with the second operating
