Abstract
A fluid-driven tool for mechanically driving a spring-grip fastener onto a shaft or rod, which fasteners are automatically insertable within the tool and may be positioned at a predetermined depth upon the shaft by means of a stroke-adjusting device.
Claims21
A fluid-driven tool for applying fasteners onto a shaft, said tool comprising:
- a housing having a front end, a back end, and defining an enclosure;
- means affixed to said housing front end for holding a fastener at an application position;
- means for serially supplying a plurality of fasteners such that a lead fastener is held at said application position by said holding means;
- means for applying said lead fastener, held at said application position by said holding means, upon said shaft;
- means movably positioned within said enclosure and coupled to said applying means for driving said applying means in a fastener-applying direction;
- a source of fluid pressure;
- means for selectively communicating said source of fluid pressure to said enclosure so as to move said driving means and said applying means so as to contact and drive said lead fastener onto said shaft;
- and
- means adjustably mounted upon said housing for engaging said driving means as said driving means is moved in said fastener-applying direction so as to adjustably limit the stroke of said driving means and said fastener applying means so as to limit the distance said lead fastener is moved relative to said shaft as said lead fastener is being applied to said shaft.

A fluid-driven tool for applying fasteners as claimed in claim wherein said enclosure is a cylinder with a longitudinal axis.
A fluid driven tool for applying fasteners onto a shaft, comprising:
- a housing;
- axial bore means defined within said housing for holding a fastener at an application position and for receiving an end of said shaft upon which said fastener is to be mounted;
- means for serially supplying a plurality of fasteners, disposed within a strip of fasteners wherein successive fasteners are connected together by means of a bridging portion, such that a lead fastener is disposed at said application position within said axial bore means;
- means for engaging a rear surface, as considered with respect to a fastener-applying direction, of said lead fastener disposed at said application position within said axial bore means and for enveloping said end of said shaft upon which said lead fastener is to be mounted so as to mount said lead fastener at a predetermined axial position upon said shaft which is located a predetermined distance from an end surface portion of said shaft which si disposed transverse to a longitudinal axis of said shaft;
- means movably positioned within said housing and connected to said engaging and eveloping means for driving said engaging and enveloping means in said fastener-applying direction;
- a source of fluid pressure;
- means for selectively communicating said source of fluid pressure to said housing so as to move said driving means and said engaging and enveloping means so as to engage said lead fastener and envelop said end of said shaft so as to mount said lead fastener upon said shaft;
- and
- tab means defined within said housing at said application position for engaging only a front surface, as considered with respect to said fastener-applying direction, of a bridging portion of said fastener strip, defined between said lead fastener disposed at said application position and a successive fastener within said fastener strip, so as to cooperate with said engaging and enveloping means and therefore facilitate separation of said lead fastener from said successive fasteners disposed within said fastener strip as said engaging and enveloping means is moved in said fastener-applying direction during application of said lead fastener upon said shaft.
