Abstract
Abstract High-speed transfer apparatus for presses has spaced carrier bars with inward article receiving configurations. The carrier bars are mounted on carrier supports for longitudinal movement therewith and for relative transverse movement with respect thereto. The carrier bars are positively connected to the cam bars for lateral in and out movement therewith and for relative sliding. The carrier supports and cam bars are independently reciprocated in phase displaced relationship so the carrier bar moves forward after the cam bar has moved inward, and so the cam bar draws the carrier outward before the carrier is returned to its first position. The carrier and cam bar are reciprocated by separate rotating cams and followers. A cam flange extends radially outward from a cylindrical body and followers are mounted on opposite sides of the flange for continuous uniform direction rotation of the followers as the cam rotates, and the followers move slides which are connected to the cam bar and carrier bar.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
243 words
Article transfer apparatus comprising: a frame, a cam slide having a horizontal sliding surface fixed to the frame, an elongated cam bar mounted on the horizontal sliding surface of the slide for movement thereon, first and second cam means, the first cam means comprising cam apertures angularly disposed with respect to an elongated direction of the cam bar, and the second cam means comprising cam followers positioned in the apertures and having axles extending outward therefrom, one of the cam means being fixed in the cam bar, and the other of the cam means being fixed in the frame, an elongated carrier mounted on the frame parallel to the cam bar and connected to the cam bar for free relative sliding movement relative to the frame and for free longitudinal sliding movement relative to the cam bar and for lateral movement with the cam bar, the elongated carrier having article engaging means on one side thereof, first reciprocating means connected to the cam bar for moving the cam bar forward and rearward in a longitudinal direction thereof, thereby causing angular translational movement of the cam bar by interaction of the first and second cam means, second reciprocating means connected to the carrier for moving the carrier forward and rearward in a longitudinal direction thereof, timing means connected to the first and second reciprocating means for operating the reciprocating means in phase-displaced relation, whereby the cam bar and carrier move longitudinally at different times.
Claim 2
Dependent Claim
243 words
Article transfer apparatus comprising: a frame, a cam slide having a horizontal sliding surface fixed to the frame, an elongated cam bar mounted on the horizontal sliding surface of the slide for movement thereon, first and second cam means, the first cam means comprising cam apertures angularly disposed with respect to an elongated direction of the cam bar, and the second cam means comprising cam followers positioned in the apertures and having axles extending outward therefrom, one of the cam means being fixed in the cam bar, and the other of the cam means being fixed in the frame, an elongated carrier mounted on the frame parallel to the cam bar and connected to the cam bar for free relative sliding movement relative to the frame and for free longitudinal sliding movement relative to the cam bar and for lateral movement with the cam bar, the elongated carrier having article engaging means on one side thereof, first reciprocating means connected to the cam bar for moving the cam bar forward and rearward in a longitudinal direction thereof, thereby causing angular translational movement of the cam bar by interaction of the first and second cam means, second reciprocating means connected to the carrier for moving the carrier forward and rearward in a longitudinal direction thereof, timing means connected to the first and second reciprocating means for operating the reciprocating means in phase-displaced relation, whereby the cam bar and carrier move longitudinally at different times.
Claim 3
Dependent Claim
42 words
The tRansfer apparatus of claim 1 wherein the first cam means apertures are disposed in the cam bar and wherein the second cam means followers comprise wheels disposed within the apertures and axles extending outward therefrom and fixed in the cam slide.
Claim 4
Dependent Claim
80 words
The transfer apparatus of claim 1 wherein the carrier has at a second side thereof opposite the article engaging surface an outward and upward extending elongated portion having a hooklike cross section, and wherein the cam bar has at a lateral side thereof adjacent the carrier an elongated portion having a complementary hooklike cross section which is interconnected with the portion of the carrier, permitting relative longitudinal sliding between the carrier and cam bar, and preventing relative lateral movement therebetween.
Claim 5
Dependent Claim
160 words
The transfer apparatus of claim 1 wherein the carrier mounting comprises elongated shafts mounted on the frame parallel to the carrier and beneath the carrier, and antifriction bearings surrounding portions of the shafts, a carrier support fixed to upper portions of the bearings, the carrier support having an upper sliding surface, elongated carrier bars mounted on the sliding surface, groove and lug interconnection means on the sliding surface and the carrier bar and the interconnection means being oriented transverse to an elongated direction thereof for permitting lateral movement of a carrier bar with respect to the support and for preventing relative longitudinal motion therebetween, and wherein a cam bar engaging means is formed on a side of the carrier bar opposite the article engaging means, and wherein the second reciprocating means is connected to the carrier support for moving the support forward and rearward on the shafts and for driving the carrier bar forward and rearward with the carrier support.
Claim 6
Dependent Claim
205 words
The transfer apparatus of claim 1 wherein the timing means comprises a drive shaft mounted for rotation on the frame, and means for rotating the drive shaft, and wherein the first reciprocating means comprises a first cylindrical body keyed to the drive shaft and having a cam flange extending radially therefrom at a smoothly varying axial position with respect to the drive shaft, cam follower rollers mounted on opposite sides of the cam flange, and axles extending upward from the follower rollers, a slide connected to the axles and having a lower surface configured for sliding on the frame and a linkage interconnecting the slide and the cam bar, and wherein the second reciprocating means comprises a second cylindrical body keyed to the drive shaft and a second radially extending cam flange having smoothly varying axial position mounted on the second body, second cam follower rollers mounted on opposite sides of the second cam flange, axles extending upward from the follower rollers, and a second slide rigidly supporting the axles, the second slide having a lower surface configured for sliding along the frame in a movement controlled by the second cam flange and second follower rollers, and second linkage means interconnecting the second slide carrier.
Claim 7
Dependent Claim
81 words
The transfer apparatus of claim 5 wherein the first linkage comprises a first connecting rod extending from the first slide toward the cam bar, a crank having a vertical axis and having a lower radial flange connected at an outer end thereof to a second end of the first rod, the crank having a second flange extending radially outward with an outer end connected to a first end of a second rod having a second end connected to the cam bar.
Claim 8
Dependent Claim
86 words
The transfer apparatus of claim 1 further comprising a second cam slide mounted on the frame parallel to the first cam slide, a second cam bar mounted on the second cam slide parallel to the first cam bar, third and fourth cam means interconnecting the frame and the second cam bar, a second carrier slidably mounted on the frame parallel to the second cam bar and connected thereto for lateral movement therewith, wherein the first and second carriers define an article receiving and treating spaCe therebetween.
