专利汇可以提供Motorized archery sight and range finder专利检索，专利查询，专利分析的服务。并且A motorized sight and range finder for archers, consisting of an attachment having a vertical slide on which two sliders are vertically movable. The sliders have sight bars which enable the archer to sight the game between them. One sight bar also has a bull''s-eye sight, to zero-in on the body of the game. A pivoted drive member on the slide is connected to the sliders in a way to not only vertically adjust the latter but also to automatically vary the spacing between them. Game which is far away and appears small, requires close spacing of the sight bars which results in their being automatically positioned vertically to a lower level, together with the bull''s-eye sight, so as to provide for a higher trajectory of the arrow, and vice versa. A gear train connected with the drive member actuates the latter. The train is driven by an electric motor powered from a battery. A reversing switch in the motor circuit controls the forward and reverse rotation of the latter. The gear train, motor, switch and a portion of the drive member are enclosed in a small housing carried by the slide.，下面是Motorized archery sight and range finder专利的具体信息内容。

权利要求

1. An archery sight and range finder comprising, in combination: a. an elongate slide, b. means for mounting the slide vertically on a central portion of an archer''s bow, c. a pair of sliders carried by and vertically movable on the slide, d. a drive member pivotally carried by the slide and having an actuating arm, e. a pair of links pivotally connected to said actuating arm at spaced-apart points thereon, f. said links being respectively pivotally connected to the sliders whereby movement of the arm shifts the sliders at different rates along the slide to vary the spacing between them and simultaneously reposition them vertically, g. a pair of projecting sight bars disposed alongside each other respectively on said sliders and arranged to be located at the path of vision of an archer who is sighting game with the bow in shooting position, h. said sight bars thereby having a variable spacing and variable vertical positioning by virtue of their being carried by the respective sliders, whereby game can be visually located between the sight bars, i. a bull''s-eye type sight carried by one of said sliders and disposed between the sight bars, for alignment with the game being sighted, j. a gear train comprising a worm gear rigidly connected to the drive member to operate the latter at a reduced speed, comprising a worm engaged with the worm gear, a second worm gear rigid with said worm, and a second worm engaged with the second worm gear, k. an electric motor having its shaft rigid with the second worm of the gear train to drive the same, l. an electric battery, m. a reversing switch having forward, reverse, and open positions, n. circuit means connecting the battery to the motor through said reversing switch, o. a housing below and carried by said slide, in which the drive member, gear train, electric motor and reversing switch are all mounted, said housing including a depending portion of smaller girth in which the reversing switch is disposed, and p. a pair of spring-biased push buttons connected to the reversing switch and protruding from a wall of the depending portion of the housing in a location enabling them to be easily and quickly actuated for effecting adjustment of the sliders.

2. A device as in claim 1, wherein: a. the sight bars comprise luminescent material adapted to glow in darkness.

3. A device as in claim 2, wherein: a. the bull''s-eye sight comprises luminescent material.

4. An archery sight and range finder as in claim 1, and further including: a. adjustment means for changing the effective length of at least one of said links.

5. A device as in claim 1, wherein: a. the sliders have hubs projecting from them in directions opposite to the projecting directions of the sight bars, b. said links being connected to said hubs.

6. A device as in claim 1, wherein: a. said slide comprises a round rod, b. said sliders comprising bored blocks through which the slide rod extends, and comprising hubs pivotally attached to the blocks, c. said links comprising round bars secured in said hubs.

7. A device as in claim 6, and further including: a. releasable fastener devices for holding the links in adjusted positions in said hubs.

8. A device as in claim 1, wherein: a. the drive member comprises an arm pivoted at one end, and b. hubs pivotally carried by said arm and having respectively secured thereto the said links.

9. A device as in claim 1, wherein: a. the slide has a bracket to which the housing is attached, and has bearings for said first worm and second worm gear.
