The width of the throat is sufficiently wide to accommodate the passage of the transverse strut or brace bar disposed in spanning relationship with, and between, the risers of a handlebar while the loop of the stem is advanced along the handlebar riser toward the central, knurled portion thereof.

Abstract: A continuous business form which includes a series of connected blanks adapted to be subsequently processed into multi-ply lottery tickets, envelopes or like articles, is produced from an endless web of sheet material. Each blank is developed from an odd number of continuous panels which span the width of the web wherein adjacent, non-abutting panels define the various plies of each article, and wherein one surface of certain of the nonabutting panels is provided with an adhesive which is not activated for adhering to other panels of the form until after original indicia has been applied to the non-abutting panels which are thereafter superposed in overlying relationship for producing the continuous series of multi-ply forms wherein each ply contains original, directly applied indicia.

Abstract: A pair of chains are secured in spaced relationship to an endless conveyor from which they depend for controlling the closing and opening of a slip loop defined by one of the chains. A flap of hide is retained in the slip loop during and after a hide pulling operation until the pulled hide has been fully elevated to a predetermined position, at which time it is released and dropped at a location adjacent but spaced from the locus of the hide-pulling operation. The closing and opening of the slip loop is a function of the relationship of the connection of the chains with the endless conveyor as it changes direction during its travel along a predetermined path.

Abstract: A hollow-cylindrical tube of dehydrated, regenerated cellulose sponge material is tightly compressed to provide an elongate member of minimal diameter having sufficient rigidity to be inserted endwise into a body opening where it will, when moistened, expand radially whereby to substantially engage the inner peripheral walls of the opening for securing it against accidental or unintentional dislodgement therefrom. When used in association with an ear canal an axial opening through the expanded member permits sound waves to reach the ear drum. The device can be used to apply medicament by expanding the compressed tube with a liquid medicament.

Abstract: A multi-ply lottery ticket or like article is formed from a single sheet of material transversely accordion folded into a set of three contiguous panels disposed in registered zig-zag relationship. The articles are formed from an endless web of sheet material transversely subdivided into a series of connected blanks each of which is transversely trisected into a set of three contiguous panels spanning the full width of the web, wherein portions of each surface of the web are provided with adhesive which is not activated for adhering to other panels until after original indicia has been applied to an upper surface of at least one panel of each blank. Thereafter, each set of panels is accordion folded into registered zig-zag relationship, abutting panels permanently bonded to one another, producing the continuous series of multi-ply tickets or like articles.

Abstract: A plurality of elongate, cylindrical articles are continuously, sequentially advanced toward and selectively introduced into the upper and lower compartments of one or the other of a pair of article-receptive chambers. A first finite number of articles are received and accumulated in the upper compartment of one chamber and then discharged and deposited, en masse, in the lower compartment of this chamber, during which a second finite number of articles are received by the lower chamber and are accumulated with the first finite number of articles deposited therein. All of the articles accumulated in the lower compartment of this chamber are then discharged, en masse, into a suitable receptacle. While the articles are being discharged from this chamber, advancing articles are automatically directed toward and likewise introduced into the upper and thereafter the lower compartments of the other chamber.

Abstract: The stepping conveyor comprises a walking beam which carries a plurality of trolley pushers or impellers adapted to advance, in one direction and in step by step fashion, a succession of trolleys that are movable along an overhead trolley rail; the walking beam incorporating structural improvements that minimize the cost of manufacture, of installation, and operation, and ensure a high degree of stability and resistance to wear in the walking beam system.

Abstract: A hide-puller includes a pair of transversely spaced, endless, flexible members which define a continuous, vertical path having a forward descending reach and a rearward ascending reach. A horizontal reaction member is secured to, carried by and spans the flexible members and is advanced therewith along the continuous path. A carcass to be stripped of hide is suspended, head-end down, from an overhead support forwardly of and adjacent the descending reach and a stationary anchor member is disposed intermediate of the reaches for securing a loosened, tail-end-adjacent flap of the hide, whereby the reaction member engages and imparts a downward, hide-pulling motion to the hide intermediate of the anchor and the carcass as the reaction member advances in the downward reach.

Abstract: A coin testing device includes one or more coin-receptive slots of specific depth, height and width for testing the flatness, thickness and diameter of like, "on-edge" coin-tokens which pass therethrough, and a rearwardly declining deck projecting from the slots for receiving and advancing acceptable coin-tokens, wherein a guide member is disposed upwardly from and substantially parallel to the deck for engaging the peripheral edge adjacent face of acceptable coin-tokens for testing the peripheral configuration thereof, wherein ultimately accepted coin-tokens are advanced across the deck and are guided by the guide member into coin-receptive discharge apertures which are disposed at substantially right angles to the slots.

Abstract: A continuous business form define a series of connected blanks adapted to be subsequently processed into multi-ply lottery tickets, envelopes or like articles, wherein each blank is developed from a plurality of contiguous longitudinal panels which collectively span the width of each blank, wherein at least one edge adjacent panel of each blank defines a cover panel including means for exposing a portion of another panel when disposed in direct overlying relationship therewith, and wherein one surface of certain of the contiguous panels is provided with an adhesive which is not activated for adhering to other panels of the blank until after original indicia has been applied to at least one panel other than said cover panel.
