Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
In a livestock headgate including a pair of upright support members and a pair of gate sections, each gate section pivotally mounted to one of the support members and having a substantially vertical, outer, animal engaging edge, whereby a confined animal''s neck may be secured between said edges when said gate sections are in a closed position, the improvement comprising: means cooperating with said gate sections for restraining the vertical movement of the confined animal''s head, and selftightening means for positioning said restraining means at different levels, said self-tightening means also including means for locking said restraining means at any one of said levels whereby said restraining means can only move into further restraining position to minimize the vertical movement of the confined animal''s head.
Claim 2
Dependent Claim
125 words
In a livestock headgate including a pair of upright support members and a pair of gate sections, each gate section pivotally mounted to one of the support members and having a substantially vertical, outer, animal engaging edge, whereby a confined animal''s neck may be secured between said edges when said gate sections are in a closed position, the improvement comprising: means cooperating with said gate sections for restraining the vertical movement of the confined animal''s head, and selftightening means for positioning said restraining means at different levels, said self-tightening means also including means for locking said restraining means at any one of said levels whereby said restraining means can only move into further restraining position to minimize the vertical movement of the confined animal''s head.
Claim 3
Dependent Claim
15 words
The improvement of claim 1 wherein said self-tightening means is a removably engagable ratchet means.
Claim 4
Dependent Claim
43 words
The improvement of claim 1 wherein said restraining means cooperates with one of said gate sections and is positioned therewith such that both said gate sections are freely movable to disengage the confined animal with said restraining means maintained in a restraining position.
Claim 5
Dependent Claim
176 words
A livestock headgate comprising a pair of upright support members; a pair of gate sections, each gate section being pivotally mounted to one support member and each section having a substantially vertical, outer, animal engaging edge, whereby an animal''s neck may be secured between said edges when said gate sections are in a closed positIon; a self-adjusting head restraining means including a carrier member slidably secured to one of the gate sections, a stop fixedly secured to said carrier member, said carrier member and said stop being vertically movable, with said stop adjacent to the engaging edge of the one gate section and disposed between both of said gate sections when said sections are in the closed position; and a ratchet means pivotally mounted to the one gate section and removably engageable with said carrier member to allow only downward movement of said carrier member and said stop while said ratchet is engaged; and said head restraining means also being positioned to allow the gate sections to freely pivot on their respective support members without restriction.
Claim 6
Dependent Claim
176 words
A livestock headgate comprising a pair of upright support members; a pair of gate sections, each gate section being pivotally mounted to one support member and each section having a substantially vertical, outer, animal engaging edge, whereby an animal''s neck may be secured between said edges when said gate sections are in a closed positIon; a self-adjusting head restraining means including a carrier member slidably secured to one of the gate sections, a stop fixedly secured to said carrier member, said carrier member and said stop being vertically movable, with said stop adjacent to the engaging edge of the one gate section and disposed between both of said gate sections when said sections are in the closed position; and a ratchet means pivotally mounted to the one gate section and removably engageable with said carrier member to allow only downward movement of said carrier member and said stop while said ratchet is engaged; and said head restraining means also being positioned to allow the gate sections to freely pivot on their respective support members without restriction.
Claim 7
Dependent Claim
131 words
An animal-engaging livestock headgate comprising a pair of upright support members; a pair of gate sections, each gate section being pivotally mounted to one of the support members and each gate section having an outer, animal-engaging edge, whereby an animal''s neck may be secured between said edges when said gate sections are in a closed position; and means for automatically tripping the pair of gate sections to the closed position, said tripping means cooperating with said animal engaging edges and engaging the chest and brisket portions of the animal as it enters the headgate, said tripping means also including an elongated triggering means for bridging the space between said engaging edges when said headgate is in a preset, open position, and means for adjusting the vertical placement of said triggering means.
Claim 8
Dependent Claim
131 words
An animal-engaging livestock headgate comprising a pair of upright support members; a pair of gate sections, each gate section being pivotally mounted to one of the support members and each gate section having an outer, animal-engaging edge, whereby an animal''s neck may be secured between said edges when said gate sections are in a closed position; and means for automatically tripping the pair of gate sections to the closed position, said tripping means cooperating with said animal engaging edges and engaging the chest and brisket portions of the animal as it enters the headgate, said tripping means also including an elongated triggering means for bridging the space between said engaging edges when said headgate is in a preset, open position, and means for adjusting the vertical placement of said triggering means.
Claim 9
Dependent Claim
35 words
The improved headgate set forth in claim 5 wherein said triggering means is secured at each end to said engaging edges, and with at least one of said ends detachably secured to said engaging edge.
Claim 10
Independent Claim
181 words
An apparatus for the handling of livestock comprising: a pair of upright support members; a pair of gate sections, each pivotally mounted to one of said support members and each having a substantially vertical, outer, animal engaging edge whereby an animal''s neck may be secured between said edges when said gate sections are in a closed position; a means for restraining the vertical head movement of an animal confined within the headgate, said restraining means cooperating with one of said gate sections and positioned thereon such that both said gate sections are freely movable to disengage a confined animal with said restraining means maintained in restraining position, said restraining means also including self-tightening means for multi-level positioning and means for locking said restraining means at each said level whereby said restraining means can only move into further restraining position; and means for automatically tripping said pair of gate sections to the closed position, said tripping means cooperating with a lower portion of said animal engaging edges and engaging the chest and brisket portions of the animal as it enters the headgate.
Claim 11
Independent Claim
181 words
An apparatus for the handling of livestock comprising: a pair of upright support members; a pair of gate sections, each pivotally mounted to one of said support members and each having a substantially vertical, outer, animal engaging edge whereby an animal''s neck may be secured between said edges when said gate sections are in a closed position; a means for restraining the vertical head movement of an animal confined within the headgate, said restraining means cooperating with one of said gate sections and positioned thereon such that both said gate sections are freely movable to disengage a confined animal with said restraining means maintained in restraining position, said restraining means also including self-tightening means for multi-level positioning and means for locking said restraining means at each said level whereby said restraining means can only move into further restraining position; and means for automatically tripping said pair of gate sections to the closed position, said tripping means cooperating with a lower portion of said animal engaging edges and engaging the chest and brisket portions of the animal as it enters the headgate.
