Abstract
Abstract A bow gun comprising a body having a channel disposed therein, the channel including a projectile discharge opening. A magazine chamber communicates with the channel for storing a plurality of projectiles for sequential discharge. A bow is mounted on the body, the bow carrying a bow string. An impulse slide is disposed for reciprocal movement within the channel and is operably connected to the bow string. A cocking slide is disposed for reciprocal movement in the channel to shift the impulse slide rearwardly in the channel. A manually actuable cocking lever is pivotally mounted to the gun body and is operably connected to the cocking slide. Actuation of the cocking lever effects rearward movement of the cocking slide to shift the impulse slide rearwardly toward a cocked position. A trigger is provided for retaining the impulse slide in a cocked position and for releasing the impulse slide for forward movement toward a projectile under the bias of the bow string. A portion of the impulse slide is disposed above the magazine chamber subsequent to discharge of one projectile to prevent premature entry of another projectile into the discharge bore. The gun body comprises a pair of housing sections releasably secured together. The housing sections are divided along a plane defined essentially by the central axis of the channel. An adaptor unit is provided for converting the gun into a ball-ejecting gun.

Claim 1
Independent Claim
204 words
A bow gun comprising: a body having a channel disposed therein, said channel including a projectile discharge bore and a cocking bore, said discharge bore having a projectile discharge opening at a forward end thereof; a magazine chamber communicating with said channel for storing a plurality of projectiles for sequential discharge; a bow mounted on said body at a forward end thereof, said bow carrying a bow string; impulse slide means disposed for reciprocal movement within said discharge bore and including a cocking head disposed in said cocking bore; said bow string being connected to said impulse slide means; cocking slide means disposed for reciprocal movement in said cocking bore relative to and ahead of said cocking head for shifting said impulse slide means rearwardly in said cocking bore; a manually actuable cocking lever means pivotally mounted to said gun body and connected to said cocking slide to effect rearward movement thereof toward said cocking head to shift said impulse slide means rearwardly toward a cocked position; and triggering means for retaining said impulse slide means in a cocked position and for releasing said impulse slide means for forward movement toward a projectile in said discharge bore under the bias of said bow string.
Claim 2
Dependent Claim
204 words
A bow gun comprising: a body having a channel disposed therein, said channel including a projectile discharge bore and a cocking bore, said discharge bore having a projectile discharge opening at a forward end thereof; a magazine chamber communicating with said channel for storing a plurality of projectiles for sequential discharge; a bow mounted on said body at a forward end thereof, said bow carrying a bow string; impulse slide means disposed for reciprocal movement within said discharge bore and including a cocking head disposed in said cocking bore; said bow string being connected to said impulse slide means; cocking slide means disposed for reciprocal movement in said cocking bore relative to and ahead of said cocking head for shifting said impulse slide means rearwardly in said cocking bore; a manually actuable cocking lever means pivotally mounted to said gun body and connected to said cocking slide to effect rearward movement thereof toward said cocking head to shift said impulse slide means rearwardly toward a cocked position; and triggering means for retaining said impulse slide means in a cocked position and for releasing said impulse slide means for forward movement toward a projectile in said discharge bore under the bias of said bow string.
Claim 3
Dependent Claim
35 words
Apparatus according to claim 1 wherein said gun body comprises a pair of housing sections releasably secured together; said housing sections being divided along a plane defined essentially by the central axis of said channel.
Claim 4
Dependent Claim
64 words
Apparatus according to claim 1 wherein said channel comprises a web slot interconnecting said discharge and cocking bores; said cocking bore being disposed above said discharge bore; said impulse slide means including an impact head slidable within said discharge bore and a web portion interconnecting said cocking head and impact head; said impact head being operable to contact and eject the projectiles being discharged.
Claim 5
Dependent Claim
43 words
Apparatus according to claim 1 wherein said impulse slide means includes a portion traveling in said discharge bore and which is disposed above said magazine chamber subsequent to discharge of one projectile to prevent premature entry of another projectile into said discharge bore.
Claim 6
Dependent Claim
33 words
Apparatus according to claim 1 wherein said impulse slide means includes a cam surface arranged to depress projectiles into said magazine chamber during retraction of said impulse slide means by said cocking lever.
Claim 7
Dependent Claim
46 words
Apparatus according to claim 1 and further including a link pivotally connected at one end to said cocking lever and pivotally connected at another end to said cocking slide to transmit force therebetween; and spring means for returning said cocking lever subsequent to a retracting operation.
Claim 8
Dependent Claim
23 words
Apparatus according to claim 1 and further including resilient buffer means operably interposed between said impulse slide means and said cocking slide means.
Claim 9
Dependent Claim
48 words
Apparatus according to claim 1 and further including a pair of sight elements disposed at the forward and rearward ends of said gun body; rail means interconnecting said sight elements and oriented in straddling relation thereto to define a carrying handle and support stand for the bow gun.
Claim 10
Dependent Claim
89 words
Apparatus according to claim 1 wherein said bow comprises a centerpiece and a pair of outer sections hingedly connected thereto, said outer sections being pivotal to a collapsed position generally parallel to the longitudinal axis of the gun body; and a pair of pins insertable between edges of said outer sections and said centerpiece to provide an orienting surface for said outer sections when the latter are positioned for operation; said pin means being constrained between said centerpiece and said outer sections by the tension of said bow string.
Claim 11
Dependent Claim
87 words
Apparatus according to claim 1 including a projectile loading tool securable in a storage compartment of said gun body; said tool including a rod; projectiles to be discharged including apertures for receiving said rod; said projectiles being aligned when installed onto said rod so as to be insertable as a unit into said magazine chamber with said gun body being in an upright position; said rod being removable from said projectiles with said gun body in an inverted position to deposit said projectiles in said magazine chamber.
Claim 12
Dependent Claim
47 words
Apparatus according to claim 10 wherein said magazine chamber is adapted to receive a charge of darts, spring means being provided to bias a charge of darts upwardly toward said discharge bore, and closable door means for retaining and compressing said spring means in said magazine chamber.
Claim 13
Dependent Claim
