The drawing depicts a horse in light harness. The four components of light harness for horses are: the bridle, the collar, the back pad and the breeching.
Number 1: throat latch - a narrow buckled strap, which is part of the bridle, and that fits loosely under the horse's throat securing the bridle in place.
Number 2: crown - the uppermost part of the bridle that fits over the horse's head directly behind the ears and supports the weight of the bridle.
Number 3: brow band - a semi-circular strap that attaches to the rest of the bridle through loop-ends. It fits below the ears and stops the bridle from slipping back onto the neck.
Number 4: blinkers or winkers - are a pair of blocked leather coverings over the eyes to confine the vision of a harness horse. They attach to the cheekpieces on the side of the bridle.
Number 5: cheekpiece - parts of the bridle that extend along the sides of the horse's head connecting the bit to the crown, brow band, blinker/winker and noseband.
Number 6: nose band - a broad strap that is loosely worn over the nose and buckles under the cheeks. It attaches to the rest of the bridle at the cheekpieces.
Number 7: bit - is the mouth piece. It attaches to the rest of the bridle at the bottom of the cheekpieces. Through the driver's lines (reins), the bit controls the speed and direction of the horse. Bits are made mainly of metal and come in different shapes and sizes. In this case, a Liverpool bit is illustrated.
Number 8: hames - part of the collar, consists of two metal or wooden arms attached top and bottom to each other. They are padded by the collar and attached to the traces. The hames take the full force of the pull.
Number 9: collar - padded item that fits around the horse's neck and cushions the shoulders against the full force of the pull. A correct fit is most important.
Number 10: terret(s) - are two metal loops on the back pad to guide the lines (reins).
Number 11: back pad - lies on the horse's back behind the withers and is held in place by the belly band. Straps extend down and carry the weight of the shafts of the vehicle.
Number 12: belly band - part of the back pad component, fits under the belly of the horse and holds the back pad in place.
Number 13: back strap - part of the breeching component, lies along the horse's back and connects the back pad, hip strap and crupper.
Number 14: hip strap - part of the breeching component, fits over the hips of the horse supporting the breeching and breeching straps.
Number 15: crupper - part of the breeching component. It is a soft padded loop fitting under the base of the tail and attaching to the hip strap with a buckle to keep the harness from slipping forward. The traditional crupper is a leather tube filled with flax seed to maintain its rounded shape and keep the leather supple.
Number 16: breeching - part of the breeching component, fits around the horse's haunches and is attached to the hip strap.
Number 17: breeching strap - part of the breeching component, attaches the hip strap and breeching to the shafts of the vehicle.
lines or reins - two leather straps running from either side of the bit to the driver, which allow the driver to communicate with the horse and control speed and direction.
traces - a pair of leather lines attaching the hames to the vehicle.
shafts - a pair of wooden or metal bars between which a horse is harnessed
to a single-horse vehicle.
